Why Does Position: Fixed Break with CSS Transforms in WebKit Browsers?

Position Fixed Inability in WebKit Browsers with CSS Transforms

In web development, integrating position fixed with CSS transforms can often lead to unexpected behavior in WebKit-based browsers. This article explores the underlying cause and provides a solution to ensure position fixed functionality is maintained.

When applying -webkit-transform to a div element, the element's position becomes relative to its parent container. This means that any child elements with position fixed will inherit this relative positioning, effectively breaking their "fixed" behavior.

The CSS Transforms specification outlines this behavior explicitly. Elements with transforms act as a containing block for fixed-position descendants, causing their fixed positioning to cease functioning.

To resolve this issue, ensure that CSS transforms are only applied to the element that should be transformed. This will maintain fixed behavior for any child elements.
