Why is Position: Fixed Not Working in Older Mobile Browsers?

Position Fixed Not Working in Mobile Browser

Problem:

Making an element fixed in position using CSS's position: fixed may not work in older versions of iOS and Android mobile browsers. The element scrolls with the page, ignoring the fixed positioning.

Cause:

older browsers like iOS < 5 and Android < 4 do not fully support the position: fixed property.

Solution:

Use -webkit-backface-visibility: hidden;

This CSS property forces the browser to treat the element as a 3D element, which enables the fixed positioning.

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

Sample Code:

Hi I m Position Fixed
