Totally agree with David, on CSS needing a selector to know if a position: sticky; element is doing its sticky thing or not.
Ideally there would be a
:stuckCSS directive we could use, but instead the best we can do is applying a CSS class when the element becomes sticky using a CSS trick and some JavaScript magic
I love it when there is a solution that isn’t some massive polyfill or something. In this case, a few lines of IntersectionObserver JavaScript and tricky usage of top: -1px in the CSS.
