Hello to recent new followers!
I guess I should give a brief introduction. I'm Josh and I've been working on the BBC's Design System team for over five years. My passion is CSS and I recently had the privilege of joining the CSSWG in the summer.
I hope to serve you all well. 🫡

A bit of a vulnerable post by me but we need your help to get us through what has been a more difficult period than 2020.

It’s been a very hard year - Andy Bell
Unlike a lot of places in tech, my company, Set Studio/Piccalilli has no outside funding. Bootstrapped is what the LinkedIn people say, I think. It’s been a hard year this year. A very hard year...

Note to self: when minuting for the CSSWG call, make sure the room is warm enough that your fingers aren't too cold to type. 😅

There's a new #CSS Working Group poll to get feedback on different names for the infamous 'Pinterest' layout.
- Since it uses many of the grid-* properties, `grid` will be in the name somewhere
- We don't use metaphors in CSS names, so `masonry` is not listed here

See https://github.com/w3c/csswg-drafts/issues/12022 for context.

If I seemed a bit quiet the last month, it's because I lost my grandma. We had the funeral on Wednesday.
I don't have a dad and it was both my mum and grandparents who I lived with and who raised me, growing up.
How I'd love to be that little boy again giving her a hug.

As an experiment, we (the Firefox team) wanted to try a new way to get feedback on which Interop proposals matter most.
So, here's a web app where you can rank the proposals you care about, giving us data we can use when reviewing which ones to champion.

A double focus ring is really useful in general but especially so with complex, themed systems. Eric Bailey shows us how to develop a really smart system, using modern CSS.

I got to speak at our internal BBC conference, today, about what I've been involved with in the CSSWG: the new meta tag for websites to opt-in to respecting the text size accessibility settings in iOS and Android.

I got to speak at our internal BBC conference, today, about what I've been involved with in the CSSWG: the new meta tag for websites to opt-in to respecting the text size accessibility settings in iOS and Android.
I've created a proposal for a new CSS style query or pseudo-class that gets the current 'used color scheme'.
"But don't we already have @media (prefers-color-scheme)?"
Yes, but authors can override the color scheme and the media query can't know that.

And the start of the talk was slightly delayed because he was taking a photo of us and somehow incorporating it into the talk. #FrontEndNorth

Here's an example of a website. The lengths of the columns are seemingly random. But they roughly correspond to ratios. With CSS grid, we can very nicely recreate the layout, combining with fluid typography. And it's nicely responsive. #FrontEndNorth
