How to Fix the \'Position Fixed\' Issue in Mobile Browsers?

Fixing Position Fixed Issue in Mobile Browsers

Problem:
Position fixed does not work on older versions of iOS and certain Blackberry browsers, causing elements to scroll along with the page.

Solution:
To address this issue, add the -webkit-backface-visibility: hidden property to the fixed element.

<code class="css">.fixed {
  position: fixed;
  top: 0;
  left: 0;
  width: 320px;
  height: 50px;
  background: red;
  -webkit-backface-visibility: hidden; /* This is the fix */
}</code>

Explanation:
The -webkit-backface-visibility property controls how an element appears when it turns away from the user and is not visible by default. Setting it to hidden forces the browser to maintain the same rendering context for the element, preventing it from being affected by scrolling.

Example:

<code class="html"><div class="fixed">
  Hi I'm Position Fixed
</div>
<div>
  <!-- Sample text -->
</div></code>

By applying the -webkit-backface-visibility: hidden property to the fixed element, you can ensure that the element stays in the same position on the screen, even in iOS and Blackberry browsers where position fixed is not fully supported.
