Implementation Example:

html
<form>
  <label for="name">Name:</label>
  <input type="text" id="name" name="name" required>
  <label for="email">Email:</label>
  <input type="email" id="email" name="email" required>
  <label for="payment">Payment Info:</label>
  <input type="text" id="payment" name="payment" required>
  <button type="submit">Checkout</button>
</form>
