I've been grappling with this issue for quite some time.
On my webpage, there is an element with a style of position:fixed;. It's set to top:0; and left:0;. However, when you scroll down the page, it does not stay fixed in position. Interestingly, if you use the "inspect element" feature on Safari or Chrome, it still highlights the element as if it's in a fixed position.
Initially, I suspected that it might have something to do with the fact that the page uses ajax to fetch content from a database and then implements infinite scrolling to continuously load more content as you scroll.
You can take a look at the page here:
Any assistance would be greatly appreciated!
Thank you, David
