re: CSS Quickies: position VIEW POST


position: sticky has like 90% browser support, and it fails quite gracefully, and it's better than using scroll-based JS positioning, so all in all using it might be a great example of progressive enhancement. That said, it does have some quirks, eg when having a parent with explicitly set overflow property.

As for position: relative, what might be the most popular use case for it is creating a new containing block for absolutely positioned elements. Basically, if you want an element with position: absolute to have 0,0 coordinates somewhere other than top left corner of the page - put position: relative on its parent to use parent's top left corner as a start.


Yeah, the problem here is the mobile browsers! The quirks here can be a big problem to make it work as you want it to work.
