My favorite new CSS feature

Hello Reader,

It’s hard to pick one thing because there is so much to pick from right now, but I think my favorite new CSS feature is anchor positioning.

Check out this navigation that I’ve put together for a project I’m working on, where the underline and link highlight is all from a single pseudo-element.

That’s all done with something like 20 lines of CSS!

And, with a handful more, I created a decent fallback for browsers that don’t support it yet, that while not as fancy, I think it does a good enough job as a fallback.

If you’re curious on how I did it, I don’t have a breakdown of this one (yet), but it’s quite similar to what I looked at in this video a little while ago, with the big difference being a couple of delays in the transitions.

And it’s only getting better from here, with Chrome having recently shipped the ability to detect which fallback you are using (if you are using them), so you can make further adjustments, which is great for things like tooltips.

There’s a lot of other great things that are coming as well, but I think anchor positioning is going to be a bit like :has(), gaining a lot of usage quite quickly as it’s support increases, because it’s easy to use (though it definitely has it’s quirks!) and is useful for so many different things.

📺 3 Powerful nesting tricks

Following up from last week’s video where I looked at the basics of nesting, this week I take a look at what we can do when we get a little more creative with how it works.

⚡ Simplified modifier classes with this CSS trick

A quick look at how we can use attribute selectors for modifier classes. This has the potential to clash with other classes, so you do need to be careful with it 🙂.

In this episode, I talk about why being an expert still matters in a world of AI tools, and how those tools can sometimes make us think we know more than we do. I also touch on imposter syndrome and the importance of knowing what we don't know.

📝 Quiz time!

It's been a long time since I've done a quiz, so it's a bit tricky, but not too hard.

Which of these would NOT center a single child element both vertically and horizontally inside its parent?

.parent { display: grid; place-items: center; }
.parent { display: grid; place-content: center; }
.parent { align-content: center; justify-items: center; }
.parent { display: flex; place-items: center; }

As per usual, you'll have to head on over to YouTube to take a stab at the quiz, and once you answer, you'll see if you were right or not.

🏁

Have a fantastic week!
