DevTools for Beginners

@kevinpowell.co and I just released a brand new (and totally free!) email course all about DevTools and how to use them in ways that actually help you debug and improve your CSS.

Inspired by Temani’s brilliant work, where he created a box using only `border-radius` and `corner-shape`, I built on his code, played with different angles, and came up with this dynamic demo.

✨ New article ✨

Are we at the start of a new era?

Chrome 140 introduced CSS Typed Arithmetic. It might seem like a minor change, but I believe it's huge as it opens the door to countless new possibilities and a whole new era of Computational CSS.

What do you think?

You know how we can’t calc() numbers with mixed data types? Well, that's changing (Chrome 140) and it might be a bigger deal that @amitsheen.bsky.social describes as "self-aware” CSS.

Starting in Chrome 140, we'll be able to calculate numeric values with mixed data types. Sounds small, but Amit demonstrates how big a deal this is, calling it Computational CSS.

I was inspired by another amazing animation from Jon Kantner, so I made a pure CSS version. 400 squares, using sibling-index() and sibling-count(), a bunch of trig functions, and some typed arithmetic. (Currently works in Chrome 140+ only)

🚀The new CSS sibling-index() and sibling-count() functions let us create staggered animations, dynamic color palettes, and even complex circular layouts with ease.
I wrote about my first experiments with these fantastic new CSS additions. So much fun! ♥️ ✨

A couple of days ago I came across Jon Kantner’s excellent color palette generator, and it reminded me that a few years back I built something quite similar (great minds and all that) back when HSL was the hot new thing.

✨ The `-path` of Least Resistance (part 2) ✨

From shapes that define boundaries to paths that drive motion. We shift to `offset-path`, where elements no longer get clipped but flow along custom routes. 🤩

The `-path` of Least Resistance (Part 2)

This time we're looking at offset-path (and friends), which can be used to create movement when animated and benefits from all the same fancy functions that we learned about with clip-path.

24 layers on the cannon, 64 balls, and not a single inline variable. All powered by sibling-index() and sibling-count().

Working with multiple elements just got way easier! 🤩

** This animation is 100% linear! **

Sure, there are spheres, curvy lines, and circular motion. Made with a few #CSS animations and some tricky keyframes. But the timing functions? Pure linear easing across the board.

This is the simplest complex animation I’ve ever made (with #CSS). It uses only two animations: a single keyframe to rotate on the Y axis, and another with a simple Y-axis translate. That's it.

The trick is knowing how to combine them in a clever way. 😉
