The Cascade is a blog about the past, present, and future of CSS.

Howdy—Robin Rendle here.

This blog keeps me in the loop with everything that’s possible with CSS lately but it’s also a reminder to celebrate the people doing the hard work building stuff for the web.

You can subscribe to The Cascade via RSS, shoot me an email if you absolutely must, or follow the feed. This project is directly supported by readers and the membership program.

Right now the newsletter is taking a bit of a break whilst I figure out a healthy publishing cadence, but you can subscribe below:

:nth-child(of)

I’m not sure how I fell of the bandwagon of Manuel Matuzović’s excellent 100 days of CSS...

It’s time to get me up to speed with modern CSS. There’s so much new in CSS that I know too little about. To change that I’ve started #100DaysOfMoreOrLessModernCSS. Why more or less modern CSS? Because some topics will be about cutting-edge features, while other stuff has been around for quite a while already, but I just have little to no experience with it.

That’s from the latest post all about this syntax I’d never seen before:

li:nth-child(even of :not([hidden])) {
  background-color: aqua;
}

The idea is to filter all of the even list elements that aren’t hidden. That is extremely useful and good to know!
