How to Design and Build Modern Homepage Hero Sections [2025]

Your homepage hero section is essentially a handshake with visitors. In the first three seconds, you're communicating what your product does, why it matters, and whether they should stick around. Most companies get this wrong. They cram features into a hero, add stock photography that looks generic, and wonder why bounce rates stay high.

Here's the reality: a well-designed hero section can increase conversion rates by 30 to 50 percent. But it's not about making things flashy. It's about clarity, intentionality, and pairing smart design with bulletproof engineering.

When a major SaaS platform recently redesigned its homepage hero, the team faced a specific challenge: how do you communicate that your product supports 11 different social platforms without making it look like a feature checklist? The solution wasn't more copy or bigger buttons. It was rethinking the entire visual approach.

In this guide, we'll break down everything you need to know about designing and building homepage hero sections that work. We're talking about the design philosophy, the technical implementation, the accessibility considerations that most teams skip, and the real-world patterns that actually move the needle.

Whether you're redesigning an existing hero or building one from scratch, you'll walk away with a complete framework for thinking about this critical piece of your website.

TL; DR

Hero sections need a clear value prop: Communicate your core benefit in 5 seconds or less, with visual storytelling that supports the message
Designer-engineering pairing accelerates results: Collaborating in real-time produces better work faster than traditional handoff workflows
Accessibility isn't optional: Proper ARIA attributes, motion detection, and keyboard navigation make your hero usable for everyone
Responsive grids require deliberate thinking: CSS Grid with mirrored containers and auto-sizing adapts elegantly to all screen sizes
Animation should enhance, not distract: Motion should respect user preferences (prefers-reduced-motion) and serve a purpose
Bottom line: A hero section is only effective if it's beautiful, functional, and accessible

The Problem With Traditional Homepage Heroes

Let's start with why most homepage heroes don't work.

The typical approach goes like this: a company decides it needs a new hero. The marketing team drafts a headline that's either too clever ("Revolutionize your workflow" tells you nothing) or too literal ("We support Facebook, Instagram, Tik Tok..."). The design team creates a static mockup with a stock photo of smiling people in business casual. Engineering gets a Figma file, squints at it for a while, and tries to recreate it in code.

The result? A hero that technically checks the boxes but doesn't create any emotional connection. It looks professional in the way that a PowerPoint presentation looks professional. Safe, but forgettable.

The old approach at many companies featured a rotating headline that cycled through platform names. "Buffer supports Facebook. Buffer supports Instagram. Buffer supports Tik Tok." From a technical standpoint, it worked. Every platform got mentioned. But from a human perspective? It felt robotic. Corporate. Like a feature list wearing a suit.

There's also the practical problem: when you try to show everything, you emphasize nothing. A hero section has maybe 5 seconds of attention before someone scrolls or leaves. Using that time to list features is like giving a toast at a wedding by reading a grocery list.

Establishing the Core Design Philosophy

Before you sketch, code, or prototype anything, you need to answer one question: What is this hero section trying to accomplish?

This sounds obvious, but most teams skip it. They jump straight to "we need it to look modern" or "we want more visual interest." Those aren't goals. Those are directions without a destination.

For a product platform, the hero typically needs to do three things simultaneously: communicate your core value prop, reduce friction to signup, and establish credibility. You need to do all three in one screen, without making the page feel crowded.

The design challenge becomes: how do you show that a platform supports multiple social networks (which establishes credibility and scope) without resorting to a boring checklist?

One approach is using visual metaphor. Instead of listing platforms, you could show them as interactive elements that feel native to the product experience. For a social media management platform, floating tiles arranged in a grid make intuitive sense. A grid is what social media feels like to users—a collection of small, equal boxes. It's a visual language they already understand.

This metaphor-first approach has a secondary benefit: it's more memorable. You're not asking someone to read "We support 11 platforms." You're showing them a visual representation that communicates the same idea faster and more effectively.

The design philosophy should also establish constraints. What's your color palette? How much animation is appropriate? Should the hero feel playful or professional? These aren't decorative decisions—they directly impact how users perceive your brand in their first few seconds.

For a social media platform, "playful but professional" makes sense. Social media is inherently fun, but if you're managing a business account, you need to know the tool is serious. So the design should feel modern and dynamic without being frivolous or over-the-top.

Moving From Design Concept to Reality: Designer-Engineering Pairing

Here's where most projects fall apart: the handoff between design and engineering.

Traditional workflow looks like this: Designer creates high-fidelity mocks in Figma. Passes them to engineering with a document explaining specs. Engineering builds it. Back-and-forth comments on small details. Timeline extends. Quality suffers. Everyone's frustrated.

A better approach is designer-engineering pairing, where a designer and engineer work together in real-time. Not just at the beginning to plan, but throughout the entire development process.

This means spending time on video calls while engineering writes code. The designer is looking at a live preview of the website. The engineer is talking through implementation approaches. They're making decisions together instead of separately.

Why does this work better? Because the final medium—the actual webpage—becomes the single source of truth. Not a Figma mockup. Not a specification document. The real thing, in the browser, where it actually matters.

This eliminates the gap between design intent and engineering reality. When an engineer says, "We can't make the animation smooth on mobile with that approach," the designer can immediately pivot and say, "Okay, what if we reduce the number of animated elements?" You're problem-solving together instead of playing telephone.

It also surfaces issues earlier. If the responsive behavior doesn't make sense, you figure it out when the code is 10% done, not 90% done. The cost of pivoting is way lower.

Practically, this requires: a shared development environment with a live preview URL that updates on every code change. The designer bookmarks that URL and has it open throughout the project. The engineer doesn't need to send screenshots. The designer sees the actual thing.

This approach reduces temporary design artifacts (all those Figma files that become obsolete) and handoff overhead. It's faster. The work quality is higher. And both the designer and engineer feel more ownership over the final product.

Breaking Down the Grid Layout System

Now we're getting into the actual mechanics.

The hero design uses a grid layout with floating tiles at various depths. Some tiles are large and clear (representing social media platform icons). Others are small, translucent, and blurred (representing emoji and decorative elements). The visual depth created by these layers gives the hero dimension and sophistication.

The challenge: this layout needs to be responsive. On a 1920px desktop screen, you have space to arrange tiles in a certain pattern. On a 375px mobile screen, that same pattern doesn't work. The grid needs to adapt intelligently based on available space.

Traditional approaches would involve creating multiple different layouts (one for mobile, one for tablet, one for desktop) and switching between them. That's maintenance overhead and often results in awkward layouts at intermediate sizes.

A better approach uses CSS Grid's responsive capabilities: create a single grid system that automatically adjusts based on available space. The trick is using auto-fit or auto-fill with minmax() values.

Here's the conceptual formula:

\text{Grid Layout} = \text{auto columns with minmax(tile-size, 1fr)}

Where tile-size is a CSS custom property (variable) that represents the size of each grid cell. By setting this to something like 3rem, you're saying, "Each grid cell should be at least 3rem wide, and if there's extra space, distribute it evenly."

But there's a complication: the hero design features horizontal symmetry. The tiles need to mirror from the center of the hero section. You can't achieve this with a single grid container.

The solution: create two separate CSS Grid containers, one for the left half of the hero (the "leading" container) and one for the right half (the "trailing" container). Each container has its own grid, with tiles positioned using CSS Grid placement properties.

The leading container positions tiles from the center outward to the left. The trailing container positions them from the center outward to the right. By using the same grid structure and tile positioning logic on both sides, you create visual symmetry without needing to hardcode x, y coordinates for every element.

This approach has real benefits:

It's responsive by default. As the screen shrinks, the grid automatically adjusts how many tiles fit per row.
It's maintainable. If you need to add a new platform or change the tile size, you update the CSS custom property, and both sides adjust automatically.
It's predictable. Every tile behaves the same way based on grid rules, not individual positioning rules.

Accessibility-First Design and Engineering

Here's a hard truth: most hero sections, including ones designed by major companies, are inaccessible. People using screen readers navigate into a visual mess. People with motion sensitivity get physically sick from animations. Keyboard-only users can't access interactive elements.

Accessibility isn't an afterthought. It's foundational. And the best way to ensure it's truly integrated is through accessibility-first design and engineering, meaning you start with an accessible foundation and preserve it throughout the design and build process.

For this hero section, that starts with understanding what's decorative and what's functional. The visual grid and tiles? Decorative. They don't need to be interactive or announced to someone using a screen reader. The headline? Functional. The signup form? Absolutely functional.

You hide decorative content from assistive technology using aria-hidden="true". This tells screen readers, "Don't announce this content. It's just visual styling." This is not the same as display: none, which removes elements from the layout. ARIA-hidden elements stay visually present but are invisible to assistive technology.

This is crucial because without it, someone using a screen reader navigates into a forest of floating tiles, each one announced individually. "Tile, tile, tile, tile..." Meanwhile, they're trying to find the actual headline and signup button. You've buried the useful content under noise.

Next challenge: animation and motion. For people with vestibular disorders (inner ear issues affecting balance and spatial orientation), certain animations can cause dizziness, disorientation, or nausea. Parallax scrolling, rapid motion, spinning elements—these can trigger physical discomfort.

The solution is the CSS media query prefers-reduced-motion. This detects whether a user has enabled "Reduce Motion" in their OS accessibility settings (available on all major operating systems now).

You respect this preference like this:

css
@media (prefers-reduced-motion: no-preference) {
  .tile {
    animation: float 3s ease-in-out infinite;
  }
}

This says: "Only apply the floating animation if the user has NOT requested reduced motion." By default, the tiles are static. If the user explicitly allows motion, then you add the animation.

Keyboard navigation is another critical piece. Anyone using a keyboard to navigate (whether through choice or necessity) needs to be able to tab through the hero and reach the signup button. Interactive elements need visible focus states. The tab order needs to make sense.

A visible focus outline isn't a bug—it's a feature. It tells keyboard users where they are on the page.

The accessibility-first mindset also influences design decisions upstream. If you're considering an interaction that's fundamentally inaccessible (like a hover-only menu), you reconsider it. Not because the designer is forced to, but because everyone on the team understands that accessibility constraints often lead to better design overall.

Handling Responsive Behavior Across Devices

Responsiveness is harder than it looks. Everyone thinks they understand it—make things smaller on mobile, larger on desktop. But achieving elegance across 10+ different screen sizes requires thoughtful architecture.

The hero section needs to work beautifully on a 320px phone, a 768px tablet, a 1024px laptop, and a 2560px ultra-wide monitor. That's not just scaling. That's architectural adaptation.

The grid system we discussed handles some of this automatically through auto-fit. But there are additional layers to consider: typography, spacing, and layout direction.

On mobile, a two-column layout might make sense (the grid on one side, headline on the other). On desktop, you might want a centered layout with the grid surrounding the headline. On ultra-wide screens, you might want the grid larger and more prominent.

One approach is using CSS container queries, which allow you to style elements based on their container's size rather than the viewport size. This is more granular and powerful than media queries.

But browser support for container queries is still rolling out. In the meantime, media queries work fine.

The key is testing at actual device sizes, not just resizing your browser window. Viewport width ≠ device width. A phone viewport is narrower than a desktop browser with dev tools open.

Responsive images are another consideration. If you're using photographs or complex graphics in the hero, you need to serve different image sizes at different breakpoints. This is where the HTML picture element and srcset attribute come in.

This serves the right image size based on the device, which matters for both visual quality and page load performance.

Finally, there's the matter of interactive elements. On desktop, an interaction might be triggered on hover. On mobile, there's no hover—you have tap. So you need to design interactions that work for both input types.

A common mistake: designing an interaction that requires hover, then bolting on a tap behavior as an afterthought. Better approach: design for tap first (more universal), then enhance with hover effects on devices that support it.

Animation Strategy and Performance

Animation is tempting. It's shiny. It catches attention. But poorly implemented animation can make a website feel slow, janky, or distracting.

For this hero, the tiles have a floating animation. They drift subtly up and down, creating a sense of liveliness and motion. But here's the thing: you can't just animate properties arbitrarily. Some properties trigger expensive repaints and reflows. Others are cheap.

The best properties to animate are transform and opacity. These don't trigger layout recalculations. The browser can optimize them at the GPU level.

Timing function matters too. Linear motion looks robotic. Easing functions (cubic-bezier, ease-in-out) look natural. The curve should match the intended feeling. For a floating effect, something with a gentle ease-in-out is appropriate. For a snappy micro-interaction, a sharp ease-out works better.

Staggering is another technique: if you're animating multiple elements (multiple tiles), start them at slightly different times. Instead of all tiles moving in sync, they move in a wave pattern. This looks more organic.

Performance monitoring matters. If your animation is running at 30fps on a modern phone, users will notice. Use your browser's dev tools to check the frame rate. Chrome Dev Tools has a Performance tab that shows rendering performance.

Target 60fps for smooth motion on most devices. 120fps on high-refresh displays. Lower than 30fps and people start seeing it as janky.

One more thing: animation duration. The floating animation is 3 seconds. That's a deliberate choice. A 1-second loop feels frenetic. A 5-second loop feels sluggish. Three seconds is in the sweet spot—long enough to feel natural, short enough to grab attention without overstaying its welcome.

Color, Typography, and Visual Hierarchy

The visual hierarchy of your hero section determines what visitors focus on first, second, and third.

Nearly always, that should be:

Headline (the core value prop)
Subheadline or supporting text (clarification or detail)
CTA button (the action you want them to take)
Everything else (visual elements, decorative elements)

Typeface choice affects how professional vs. playful the hero feels. A sans-serif font (Helvetica, Inter, Roboto) feels modern and clean. A serif font (Georgia, Garamond) feels more traditional. A rounded sans-serif (Nunito, Raleway) feels friendly.

For a social media platform, a clean sans-serif makes sense. You want to feel trustworthy but not stuffy.

Typeface hierarchy is about size, weight, and spacing. Your headline should be noticeably larger than your subheadline. The differences should be deliberate.

A common mistake: making all text only slightly different sizes, so nothing stands out. Better to have clear jumps: headline at 48px, subheadline at 18px, body text at 14px. The ratios matter more than the absolute sizes.

Color serves multiple purposes: brand identity, visual interest, and functional signaling (like making buttons stand out).

Your primary brand color should appear in your CTA button. This draws the eye to the action. Your accent colors can appear in decorative elements (like the tile backgrounds).

Be cautious with color contrast. Text needs sufficient contrast against its background to be readable. The WCAG standard is a contrast ratio of at least 4.5:1 for normal text, 3:1 for large text.

You can check contrast using tools like Web AIM Contrast Checker. Text that looks good to you might be illegible to someone with low vision or color blindness.

Spacing (whitespace) is often underestimated. The hero needs breathing room. If your headline is jammed up against the top of the screen with tiles cluttering around it, it feels cramped. Generous spacing makes the hero feel premium and intentional.

Performance Optimization and Loading

A beautiful hero section that takes 5 seconds to load is a disaster. Users will bounce before they ever see it.

Performance optimization starts with understanding what's actually expensive. Images, animations, and scripts are the usual culprits.

Images need to be optimized: right format (WebP for most cases, JPEG for older browsers), right size (mobile gets smaller files), right compression (balance quality and file size).

For decorative elements in the hero (like backgrounds or pattern overlays), SVG is often better than PNG or JPEG. SVG files are typically smaller and scale perfectly at any resolution.

SVG also allows for animation and dynamic styling with CSS, giving you lots of flexibility.

JavaScript should be minimized. If you're detecting prefers-reduced-motion or setting CSS variables, you need JavaScript. But the script should be small and fast. Lazy-load additional scripts if they're not needed immediately.

Critical rendering path optimization means deferring non-essential resources. Your hero CSS should be inlined or critical. Non-critical CSS can load asynchronously. The same goes for JavaScript.

Images can be lazy-loaded if they're below the fold:

But be careful: don't lazy-load the hero image if it's above the fold (visible on page load). That defeats the purpose.

Font loading affects performance too. If you're using web fonts, they might block text rendering while loading. Use font-display to control this behavior:

With font-display: swap, the browser uses a fallback font immediately and swaps to your custom font when it loads. This ensures text is readable right away.

Core Web Vitals are metrics Google uses to measure page experience. They're important for SEO. The three main vitals are:

Largest Contentful Paint (LCP): How quickly the hero section renders. Target: under 2.5 seconds.
Cumulative Layout Shift (CLS): How much content moves around while loading. Target: less than 0.1.
Interaction to Next Paint (INP): How quickly the page responds to interactions. Target: under 200ms.

Optimizing your hero helps with all three. A fast-loading image improves LCP. Reserved space for elements prevents layout shifts (CLS). Efficient JavaScript keeps INP low.

You can measure these with tools like PageSpeed Insights or Web Vitals.

Testing and Validation Strategy

Before shipping a hero section, you need to test it across browsers, devices, and user scenarios.

Browser compatibility: Test on Chrome, Firefox, Safari, and Edge. Some CSS features aren't supported universally. Use caniuse.com to check support.

Devices: Test on actual devices if possible. Emulation is helpful, but the real thing is better. At minimum, test on a modern flagship phone, an older budget phone, a tablet, and a desktop at various viewport widths.

Accessibility testing: Use automated tools like Axe or WAVE to catch obvious issues. But automated testing catches maybe 30% of accessibility problems. Manual testing with screen readers is essential.

Performance testing: Use Lighthouse (built into Chrome Dev Tools) to get a performance score and specific recommendations. Also use WebPageTest for detailed waterfall charts.

User testing: Show the hero to real users (or at least representative users). Ask them what they think the product does. Ask if they'd click the CTA. Observe whether they instinctively know where to click.

A/B testing: Deploy the new hero to some users and keep the old version for others. Measure conversion rate differences. If the new hero is better, gradually roll it out to everyone.

Analytics: Track which users click the CTA, how far down the page they scroll, and bounce rate. These metrics tell you if the hero is working.

Monitoring in production is crucial. Set up real user monitoring (RUM) to catch performance issues or errors that didn't appear in testing.

Tools like Sentry track JavaScript errors. Tools like DataDog or New Relic track performance metrics. These give you visibility into real-world behavior.

Common Mistakes and How to Avoid Them

Let's talk about what goes wrong with hero sections.

Mistake 1: Too Much Text

A hero paragraph that's 3-4 sentences long is competing with itself. Pick the one sentence that's most compelling. Cut the rest. If it's important, it belongs in the section below the hero, not in the hero itself.

Mistake 2: Weak Value Prop

"The leading platform for social media" tells me nothing. What does it actually do? Why should I care? Better: "Publish, schedule, and analyze all your social media from one place." Now I understand immediately.

Mistake 3: No Clear CTA

If the button text is ambiguous ("Click here," "Submit"), users don't know what happens. Be specific: "Start free trial," "Sign up for free," "Schedule a demo."

Mistake 4: Inaccessible Interactions

If something requires a hover, keyboard users can't access it. Design for keyboard first.

Mistake 5: Poorly Optimized Images

A 5MB image in your hero kills performance on mobile. Compress ruthlessly. Use the right format.

Mistake 6: Animations That Distract

Animations should support your message. If they're just there because animations are cool, remove them.

Mistake 7: Inconsistent Branding

Your hero should feel like it's part of your product. If the colors, fonts, or tone don't match the rest of your website, something's off.

Mistake 8: No Mobile Testing

Your desktop design might look perfect. On mobile, it might be unreadable or require massive scrolling. Test on actual mobile devices.

Mistake 9: Low Contrast Text

Yellow text on white background might look cool. It's also illegible. Check contrast ratios.

Mistake 10: Complex Interactions That Aren't Obvious

If your hero has interactive elements, users need to intuitively know they're interactive. Use visual cues: hover states, cursor changes, clear buttons.

Advanced Techniques: Building Interactive Heroes

Once you understand the basics, you can layer in more sophisticated interactions.

Parallax Scrolling: Background elements move slower than foreground elements as the user scrolls, creating depth. This can be beautiful, but it can also trigger motion sensitivity issues. Only use it if you're respecting prefers-reduced-motion.

Scroll-Triggered Animations: Elements animate when they come into view. This is more engaging than static elements.

Hover States: On desktop, hover over an element to reveal more information. This can make the hero feel responsive and interactive.

Form Interactions: If your CTA has a form, you can provide real-time feedback. Validate email as the user types. Show password strength. These interactions feel modern and reduce friction.

Video Backgrounds: Instead of a static image, play a short looping video in the background. This grabs attention but make sure it's optimized and doesn't impact performance.

Interactive 3D Elements: Using libraries like Three.js, you can embed 3D models in your hero. This can be eye-catching but adds significant complexity and can hurt performance.

With any advanced technique, ask yourself: does this add value or just complexity? If it looks cool but doesn't serve the user, cut it.

Future Trends in Hero Design

The web evolves. Here are patterns emerging.

AI-Generated Visuals: Rather than static images, some companies are using AI to generate unique visuals for each user. This personalization can increase engagement.

Generative Animation: Animations that are procedurally generated rather than keyframed. These can feel organic and unique.

Voice-Activated Interactions: Voice queries becoming more common. Some hero sections might include voice input.

VR and WebXR: As virtual reality becomes more accessible, some experiences might include VR elements accessible through the browser.

Progressive Enhancement: Building features that work without JavaScript, then enhancing with JavaScript if available. This ensures the hero is robust even if something breaks.

Micro-interactions: Small, subtle feedback for every interaction. Buttons that provide haptic feedback. Forms that react to input. These feel premium.

Accessibility as Baseline: Accessibility requirements are becoming law in more jurisdictions. Hero sections designed with accessibility from the start are table stakes, not nice-to-have.

The underlying principle: hero sections should evolve as technology evolves, but the core job stays the same. Communicate value clearly. Make it easy to take the next step. Make everyone feel welcome.

Measuring Hero Section Success

You've built a beautiful hero. Now, did it actually work?

Key metrics to track:

Click-Through Rate (CTR): Percentage of visitors who click the CTA. Benchmarks vary by industry, but 2-5% is typical for hero CTAs. If yours is lower, the headline or CTA text might need work.

Conversion Rate: Percentage of visitors who actually sign up or take your desired action (not just click). This accounts for dropoff between page and signup completion.

Bounce Rate: Percentage of visitors who leave without taking any action. A high bounce rate suggests the hero didn't grab attention.

Time on Page: How long visitors spend on the page. Short time suggests they left quickly (bad). Long time suggests they're engaged (good).

Scroll Depth: How far down the page visitors scroll. If most people don't scroll past the hero, the hero might not be compelling enough for them to want to learn more.

Device/Browser Breakdown: Are certain devices or browsers underperforming? This might indicate a technical issue or poor responsive design.

Set up analytics to track these metrics. Most analytics platforms (Google Analytics, Mixpanel, Amplitude) can help.

A/B testing is powerful: deploy a new hero to 50% of users, keep the old one for 50%, and measure which converts better. If the new one wins by a statistically significant margin, roll it out fully.

Measurement loops back to design. If metrics show users aren't clicking the CTA, test a different button color or text. If bounce rate is high, maybe the headline isn't clear.

Hero sections are living things. They should evolve based on data.

Integrating Runable for Content and Workflow Automation

When managing a website redesign like this—coordinating design, engineering, content, and testing—coordination becomes challenging. This is where workflow automation tools become valuable.

Runable offers an AI-powered platform that helps teams automate documentation, presentation generation, and report creation. For a project like a homepage redesign, you can use Runable to automatically generate design systems documentation, create stakeholder reports on testing results, and produce presentations summarizing design decisions.

The workflow might look like: designer and engineer pair on the implementation, generate a design documentation report with Runable, run A/B tests, then use Runable to create a performance report showing the results. Starting at just $9/month, it's an efficient way to keep stakeholders informed without manual document creation.

Bringing It All Together: The Complete Process

Let's summarize the full workflow for designing and building a hero section:

Phase 1: Discovery and Strategy

Define your core value prop in one clear sentence
Identify what you want users to do (click CTA, scroll to learn more, etc.)
Establish design principles (playful? professional? minimalist?)
Research competitors to identify gaps

Phase 2: Design and Pairing

FAQ

What is a hero section in web design?

A hero section is the large banner area at the top of a webpage, typically containing a headline, supporting text, visual elements, and a call-to-action button. It's called a "hero" because it should be the hero of the page—the most important, most prominent element that captures attention immediately.

How do I make my hero section mobile-friendly?

Mobile-friendly hero sections require responsive typography (larger font sizes scale down gracefully), flexible layouts that adapt to narrow viewports (CSS Grid with auto-fit works well), and optimized images served at appropriate sizes. Test at actual mobile device dimensions, not just browser resizing, and ensure tap targets (buttons) are at least 44x44 pixels for easy interaction.

What are the best practices for hero section copy?

Keep your headline to one clear sentence that communicates your core value proposition. Support it with a brief subheadline (2-3 sentences max) that adds context or addresses a common question. Make your CTA button text specific and action-oriented ("Start free trial" rather than "Click here"). Remember: users scan headlines in 2-3 seconds, so clarity beats cleverness.

How do I ensure my hero section is accessible?

Mark decorative elements with aria-hidden="true" to hide them from screen readers, use semantic HTML (real buttons for buttons, headings with proper hierarchy), ensure sufficient color contrast (4.5:1 ratio for normal text), respect the prefers-reduced-motion preference for animations, and make all interactive elements accessible via keyboard. Test with actual screen readers and keyboard-only navigation before launching.

What animation techniques work best for hero sections?

Animate using transform and opacity properties rather than positional changes (top, left) for better performance. Keep animations purposeful—they should enhance the message, not distract from it. Use gentle easing functions (cubic-bezier) rather than linear motion. Respect prefers-reduced-motion by only enabling animations if explicitly allowed. Stagger animations across multiple elements for organic motion. Aim for 60fps on modern devices.

How do I measure if my hero section is working?

Track click-through rate on the CTA, conversion rate (percentage completing signup), bounce rate, scroll depth, and time on page. Use A/B testing to compare different hero designs and let metrics decide which wins. Monitor Core Web Vitals (LCP, CLS, INP) to ensure performance is strong. Most analytics platforms (Google Analytics, Mixpanel) provide these metrics out of the box.

What's the optimal height for a hero section?

A hero section should be at least 100vh (one full viewport height) on desktop, allowing the entire hero to be visible without scrolling. On mobile, you might use 80-100vh to leave a hint of the content below. Avoid making it so tall that users have to scroll significantly before reaching the main content. The goal is balance: prominent but not excessive.

Should I use video or images in my hero section?

Both can work, but images load faster than video. If using video, ensure it's optimized (compressed, short duration), muted by default (for autoplay), and includes a fallback image. Video is more engaging but riskier from a performance perspective. Test performance on slower devices and connections before committing to video.

How do I handle multiple CTA options in a hero?

Limit yourself to one primary CTA (the main action you want) and optionally one secondary CTA. Too many options create choice paralysis. If you have multiple audience segments (existing users vs. new users), use personalization to show different CTAs, not multiple buttons on the same hero. Secondary CTAs can link to signup, demo requests, or documentation, but they should be visually de-emphasized compared to the primary action.

Conclusion

Your homepage hero section is your first impression with visitors. In three seconds, you communicate what you do, why it matters, and whether they should stick around. Everything on that page—the headline, the visuals, the interactions, the spacing—should work in concert toward that single goal.

The old approach—listing features, using generic imagery, creating an animated carousel of platform names—doesn't work. It's boring. It doesn't differentiate. It doesn't move the needle.

The modern approach is different. You start with clear strategy: what's the core value prop? You design with metaphor and visual storytelling: how can you show, not tell? You build with both eyes on performance and accessibility: who are you leaving behind? You measure everything: is this working? You iterate based on data: what can we improve?

You pair designer and engineer to move fast and catch problems early. You respect accessibility preferences so everyone can use the website. You optimize for performance so it loads quickly everywhere. You test with real users to validate assumptions.

The result is a hero section that doesn't just look beautiful, but actually works. It communicates. It converts. It sets the tone for the entire experience.

If you're redesigning your homepage, start here. Spend time on the hero. Get it right. The rest of the page benefits from a strong foundation.

And if you find yourself coordinating across teams—getting stakeholder buy-in, generating reports, creating documentation—remember that tools like Runable can streamline that overhead, letting you focus on design and engineering rather than manual document creation.

The hero section isn't just part of your website. It's the part that makes the first impression. Make it count.
