JavaScript doesn’t get executed on very old browsers when native syntax for new language features is encountered. However, thanks to GitHub being built following the principle of progressive enhancement, users of older browsers still get to interact with basic features of GitHub, while users with more capable browsers get a faster experience.
That’s the way to do it!
Concepts like progressive enhancement allow us to deliver the best experience possible to the majority of customers, while delivering a useful experience to those using older browsers.

And by LLMS I mean: (L)ots of (L)ittle ht(M)l page(S).
I really like this approach: using separate pages instead of in-page interactions. I remember Simon talking about how great this works, and that was a few years back, before we had view transitions.
I build separate, small HTML pages for each “interaction” I want, then I let CSS transitions take over and I get something that feels better than its JS counterpart for way less work.
A handy one-pager for front-end web developers:
Here are ways to keep track of what you can use, of what’s new in web browsers, and ways you can influence the development of the platform by making your voice heard.
- Springy easing with
linear()- Typed custom properties
- View transitions for page navigation
- Transition animation for
dialogandpopover- Transition animation for
details- Animated adaptive gradient text
I really like the way that the thinking here is tied back to Bert Bos’s original design principles for CSS.
This is a deep dive into the future of CSS layout—make a cup of tea and settle in for some good nerdiness!
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).
Technically, websites can do just about anything that native apps can do. And yet the actual experience of using the web on mobile is worse than ever.
It’s almost as though humans prefer to use post-hoc justifications rather than being rational actors.
A genuinely inspiring event.
Browser are user agents, not developer agents.
Mobile Safari doesn’t support the min and max attributes on date inputs.
