Why is `position: fixed` not working properly in mobile browsers and how can I fix it?

Position fixed not working in mobile browser

While the position: fixed property should keep an element fixed on the screen as the page scrolls, it may not work as expected in older versions of mobile browsers like iOS and Android. To overcome this issue, we can utilize the -webkit-backface-visibility: hidden property.

The -webkit-backface-visibility property is used to optimize the rendering performance of an element by determining whether to render the back face of the element. By setting it to hidden, the browser is instructed to hide the back face of the element, which addresses the problem with position: fixed not working correctly.

Here's an example that demonstrates how to use this property:

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

<code class="html"><div class="fixed">
  Hi I m Position Fixed
</div>
<div>
  sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />sample text<br />
</div></code>

By adding -webkit-backface-visibility: hidden; to the CSS, the element with the fixed class will remain fixed on the screen even in older versions of iOS and Android browsers.
