Hello Reader,

First up, make sure you update your browser, because there is a zero-day CSS vulnerability.

In other news, one of the joys of being over forty is managing to throw out your back while you sleep. Luckily I already had a physio appointment lined up this week for another injury… so yeah, things are going great over here!

Other than that, things are going well, though. I’ve made some good progress on my big update of CSS Demystified. I’m behind schedule as usual, but less so than normal 😆.

I’ve also started putting some time into creating a new version of my slide deck for my upcoming talk at Smashing Conf Amsterdam.

This is the third time I’ve remade it, and the second time I’m using Astro to do it, because yes, I’d rather use HTML/CSS to make slides than some slide deck options. It leaves a lot more doors open, including adding interactive examples in the slides, really easily.

I won't get into why I'm remaking them for the third time, but more importantly, I’m also making them better for sharing. The old versions were hard-coded for 1920x1080. This time, I’m making them responsive and easier to navigate, so I won’t feel embarrassed to share them now.

Once I get them working a bit better and clean up the code, I’ll probably open up the code so anyone can use them 🙂.

🙋‍♂️ What I’ve been up to this week

📺 5 CSS fouls that I see way too often

A look at five CSS fouls that I see seasoned developers make, including myself!

(also, don’t blame me for the thumbnail 😅)

⚡ cqi to the rescue

A look at using cqi for the background size of a gradient on a progress bar.

I also recorded this at a 1:1 ratio, instead of the typical 9:16 for Shorts. It gives me more space to show the code, works better on anything other than phones, and I think it works fine on them too, with a few people commenting that it works better since the icons don't cover as much, so I'll probably stick with it for a bit.

Hello Reader, Back in October, I travelled to Minneapolis to create a course with Frontend Masters, and while I was there, I recorded my experience so that I could share a behind-the-scenes look at what it was like. The first two videos in that series are now up on my second channel. This is something I’ve never done before, so there are some rough edges here and there, but I’m pretty happy with how they turned out! The final two episodes will come out this week. 🙋♂️ What I’ve been up to this...

Hello Reader, When I first started teaching CSS, I quickly realized that while I could muck around and get a layout to come together, I didn't actually understand much about CSS. Students would ask questions about why something worked the way it did, and I wouldn't have an answer. I started looking for resources that explained why things behaved the way they did, so I could understand them better and, in turn, teach them better, but I struggled to find any that did. Everything would teach you...

Hello Reader, First off, I completely forgot to send this newsletter last week, so this week’s has all my content from the past two weeks. As for the main topic of this week, after eight years, I’ve finally redesigned my homepage. For someone who talks about CSS all the time, I was a little embarrassed that I hadn’t redesigned it sooner. I think the old design was fine, and aged pretty well, but it wasn’t really anything great either. The new one is a bit more of a minimal approach, but where...
