Browser support

There was a discussion at Clearleft recently about browser support. Rich has more details but the gist of it is that, even though we were confident that we had a good approach to browser support, we hadn’t written it down anywhere. Time to fix that.

This is something I had been thinking about recently anyway—see my post about Baseline and progressive enhancement—so it didn’t take too long to put together a document explaining our approach.

You can find it at browsersupport.clearleft.com

We’re not just making it public. We’re releasing it under a Creative Commons attribution license. You can copy this browser-support policy verbatim, you can tweak it, you can change it, you can do what you like. As long you include a credit to Clearleft, you’re all set.

I think this browser-support policy makes a lot of sense. It certainly beats trying to browser support to specific browsers or version numbers:

We don’t base our browser support on specific browser names and numbers. Instead, our support policy is based on the capabilities of those browsers.

The more organisations adopt this approach, the better it is for everyone. Hence the liberal licensing.

So next time your boss or your client is asking what your official browser-support policy is, feel free to use browsersupport.clearleft.com

New Web Development. Or, why Copilots and chatbots are particularly bad for modern web dev – Baldur Bjarnason

The paradigm shift that web development is entering hinges on the fact that while React was a key enabler of the Single-Page-App and Component era of the web, in practice it normally tends to result in extremely poor products. Built-in browser APIs are now much more capable than they were when React was first invented.

An origin trial for a new HTML <permission> element  |  Blog  |  Chrome for Developers

This looks interesting. On the hand, it’s yet another proprietary creation by one browser vendor (boo!), but on the other hand it’s a declarative API with no JavaScript required (yay!).

Even if this particular feature doesn’t work out, I hope that this is the start of a trend for declarative access to browser features.

With great power, comes great creativity: thoughts from CSS Day 2024 · Paul Robert Lloyd

Here’s Paul’s take on this year’s CSS Day. He’s not an easy man to please, but the event managed to impress even him.

As CSS Day celebrates its milestone anniversary, I was reminded how lucky we are to have events that bring together two constituent parties of the web: implementors and authors (with Sara Soueidan’s talk about the relationship between CSS and accessibility reminding us of the users we ultimately build for). My only complaint is that there are not more events like this; single track, tight subject focus (and amazing catering).

Intent to Ship: View Transitions Same-Origin Navigation

Finally! View transitions for multi-page apps (AKA websites) will be landing in Chrome soon—here’s hoping other browsers follow suit. Mozilla are up for it. Apple are, as usual, silent on their intentions.

Nice to see a blog post of mine referenced to show that this is a highly-requested feature. Blogging gets results, folks!

An alternative proposal for CSS masonry  |  Blog  |  Chrome for Developers

Rachel responds to Jen’s recent post with the counter-argument; why masonry should be separate from grid.

I’m not entirely convinced. We heard performance issues as a reason why we could never have container queries or :has, but here we are. And the syntax for a separate masonry spec borrows so heavily from grid that it smells of redundancy.
