Why this works

Using the backdrop-filter property allows us to apply a smooth blur effect behind a semi-transparent form, creating a modern frosted glass look that enhances focus without distracting from the content.

Source Code

<div style="background: rgba(255, 255, 255, 0.2); backdrop-filter: blur(10px); padding: 2rem; border-radius: 20px; box-shadow: 0 8px 32px rgba(0, 0, 0, 0.2); width:100%; max-width: 400px;">
  <form>
    <div class="mb-3">
      <input type="text" class="form-control" placeholder="Your Name" required>
    </div>
    <div class="mb-3">
      <input type="email" class="form-control" placeholder="Your Email" required>
    </div>
    <div class="mb-3">
      <textarea class="form-control" rows="4" placeholder="Your Message" required></textarea>
    </div>
    <button type="submit" class="btn btn-primary w-100">Send Message</button>
  </form>
</div>
