Nada Rifki demonstrates the scroll-snap-type and scroll-snap-alignCSS properties. I like that the demo shows that the items in the scrolling container can be different sizes. It is the edges of those children that matter, not some fixed snapping distance.

I like Max Kohler’s coverage as well, which includes a demo where the snapping can happen in multiple directions.

This is one of those things where, if you didn’t know about it, it’s worth a solid golf clap … Read article “How to use CSS Scroll Snap”

But it kinda is!

:nth-child(2 of .bar) { }

Ben Myers covers some clear examples of where CSS totally changes what some screen readers announce. For example, some screenreader will see text-transform: uppercase; on a button label that says “Add” and read it like an abbreviation, “A.D.D.”

These cases of CSS messing with our screenreader announcements are initially shocking, perplexing, and maybe even appalling. After all, they seem to conflict with our mental model of CSS, one that’s likely been instilled in us since we started learning web development:
