How to Set the Width of a Fixed-Positioned Div Relative to Its Parent Div?

Expanding the Width of a Fixed-Positioned Div Relative to Its Parent Div

In web development, it can be challenging to accurately determine the width of a "position: fixed" div relative to its parent div. This problem arises when the div's width is set to 100%, resulting in the div taking up the entire width of the browser window instead of respecting the parent div's width.

To solve this issue, one solution involves applying "width: inherit" to all inner divs within the parent div. By inheriting the width from their parent, these inner divs will correctly adjust their width based on the parent div's width.

For browsers that do not support "width: inherit," a JavaScript solution may be necessary. This solution would dynamically adjust the width of the fixed div based on the parent div's width, ensuring a more accurate width determination.
