jQuery and Mobile Devices

1. Touch Events Support

jQuery does not natively support mobile-specific touch events like touchstart, touchend, etc., but you can still bind them using standard jQuery syntax.

This is useful for handling mobile interactions such as swipes, taps, or touch gestures.

Example: Change text on touch

<div id="touch-area" style="padding:20px; background:#f0f0f0;">
  Touch me on mobile (or click on desktop)
</div>

<script>
$(document).ready(function(){
  $('#touch-area').on('touchstart click', function(){
    $(this).text('Touched or Clicked!');
  });
});
</script>

2. Responsive Design Helpers

While jQuery itself doesn't offer CSS media queries, you can use it to add or remove classes, adjust styles, or detect screen sizes for responsive behavior.

Example: Show different message based on screen width

<div id="screen-msg"></div>

<script>
$(document).ready(function(){
  if ($(window).width() < 600) {
    $('#screen-msg').text('Mobile screen detected');
  } else {
    $('#screen-msg').text('Desktop or tablet screen detected');
  }
});
</script>

3. jQuery Mobile (Optional Overview)

jQuery Mobile is a separate framework built on top of jQuery that offers touch-optimized UI widgets and navigation for mobile apps.

It is no longer actively maintained for modern projects, but it was once very popular for quick mobile site development.

Example: jQuery Mobile basic page (visual only — not functional here)

<!-- jQuery Mobile Page Structure -->
<div data-role="page" id="home">
  <div data-role="header">
    <h1>Welcome</h1>
  </div>

  <div data-role="content">
    <p>This is a jQuery Mobile page.</p>
    <a href="#next" data-role="button">Next Page</a>
  </div>

  <div data-role="footer">
    <h4>Footer</h4>
  </div>
</div>

<div data-role="page" id="next">
  <div data-role="header">
    <h1>Next Page</h1>
  </div>

  <div data-role="content">
    <p>You are now on the next page.</p>
    <a href="#home" data-role="button">Back</a>
  </div>
</div>

Note: For the above to work, you'd need to include jQuery Mobile CSS and JS files, which are not shown here due to project limitations.

Recommendation: For modern development, use CSS Flex/Grid and libraries like Bootstrap or Tailwind instead of jQuery Mobile.
