How can the use of divs in PHP contact forms impact the overall responsiveness and user experience of a website?

Using divs in PHP contact forms can impact the overall responsiveness and user experience of a website by potentially causing layout issues, especially on different screen sizes. To improve responsiveness, it's recommended to use CSS frameworks like Bootstrap to create responsive contact forms that adjust to different screen sizes.

<div class="container">
  <form action="submit_form.php" method="post">
    <div class="form-group">
      <label for="name">Name:</label>
      <input type="text" id="name" name="name" class="form-control">
    </div>
    <div class="form-group">
      <label for="email">Email:</label>
      <input type="email" id="email" name="email" class="form-control">
    </div>
    <div class="form-group">
      <label for="message">Message:</label>
      <textarea id="message" name="message" class="form-control"></textarea>
    </div>
    <button type="submit" class="btn btn-primary">Submit</button>
  </form>
</div>
