Good day. Is it possible to use custom pseudo classes, that would adjust size and look of elements inside sticky header so that I will not need to use custom css?
My idea is to be able defined own pseudo class, eg. :scrolling, which would resolve to custom selector, eg. header.sticky.scrolling, and while having the pseudo class active, I can define custom look of selected elements. I have tried but nothing seems to work so maybe writing extra CSS is the only way?
