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

Howdy—Robin Rendle here. I started this side project back in May because I wanted a dedicated place to learn-out-loud about all the exciting things that’s happening in the world of CSS.

And so many exciting things are happening!

Right now we’re living through a golden age: what was once a language that was easy to make fun of has transformed into a serious and expressive toolkit for building visual interfaces. Although making fun of CSS was always lame, today, in 2024, it shows a deep lack of curiosity. The train has left the station. CSS rules. Get with the program.

But this didn’t happen randomly. Thousands of dedicated, smart folks have worked tirelessly over decades to get us to this point where CSS is—in this humble blogger’s opinion—the best design tool ever made. Every day some new super power is unlocked for us in browsers and with each new power the web becomes a better place, thanks to them.

So this blog exists to keep me in the loop and somewhat up to date with everything that’s possible with CSS but also it’s a reminder to celebrate the people doing the hard work building these tools for us.

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:

Javascript free navigation

Thanks to Andy Bell’s ever-so-good newsletter, The Index, I found myself ooo-ing and aaa-ing at Michelle Barker’s excellent post from back in May about creating a JavaScript-free menu with the latest bells and whistles like anchor-positioning and the Popover API:

Anchor positioning in CSS enables us to position an element relative to an anchor element anywhere on the page. Prior to this we could only position an element relative to its closest positioned ancestor, which sometimes meant doing some HTML and CSS gymnastics or, more often than not, resorting to Javascript for positioning elements like tooltips or nested submenus.

There’s a lot of good examples in that post that are worth checking out but one thing that stuck out to me was the <menu> HTML element which we can use like this for a series of interactive actions:

</menu> have I never used this before!?
