Scrollbars

CSS deep-dive: matrix3d() for a frame-perfect custom scrollbar

I haven’t checked how accessible this is, and I’m torn on the concept of custom scrollbars, but this is interesting at the very least:

Custom scrollbars are extremely rare and that’s mostly due to the fact that scrollbars are one of the remaining bits on the web that are pretty much unstylable (I’m looking at you, date picker). You can use JavaScript to build your own, but that’s expensive, low fidelity and can feel laggy. In this article we will leverage some unconventional CSS matrices to build a custom scroller that doesn’t require any JavaScript while scrolling, just some setup code.

TL;DR:

You don’t care about the nitty gritty? You just want to look at the Nyan cat demo and get the library? You can find the demo’s code in our GitHub repo.
