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
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*/ }</code>
Sample 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>sample text <br>sample text <br>sample text <br>sample text </div></code>
This solution has been tested and works smoothly in most mobile browsers, including older versions of iOS and Android.
