QQ about Dark Mode Toggles on websites

How many options do you show to users?

- Three values: System, Light, Dark
- Two values: Light, Dark (with one of them mapping to “System” behind the scenes).

Why the one or the other?

(I have an opinion about it, but I’m looking for external input)

One of the things that we at Chrome have been thinking about for a while now is a way to do declarative route and navigation matching in CSS. Together with Noam Rosenthal and David Baron I’ve been working on it for the past few months.

After an initial introduction at the CSS Working Group back in January, and a quick feedback session at CSS Day in June, we think we have something that is ready for further discussion.

At next week’s CSS Working Group F2F (face-to-face) meeting in Berlin, we’ll be presenting our current line of thinking. This post is a quick intro to the concepts we’ll be covering.

“Implement at-rule function for use with @supports”

See https://brm.us/at-rule for the details on this one.

We already did an initial pitch of this at @cssday back in June, and a quick read of the room confirmed we were on to something.

More feedback can’t hurt of course, so please reach out (or leave a comment at the CSSWG issue) if you have _any_ feedback 😊

In https://brm.us/styling-the-navigation I jotted down a quick intro to the concepts that we’ll be introducing:

1. Define Routes with @route
2. Query the navigation with @navigation
3. Select the navigation trigger with :nav-source
4. Advanced link selection with :link-to()

(And url-pattern() woven throughout)

One of the things that we at Chrome have been thinking about is a way to do declarative route and navigation matching **in CSS**.

Together with @nomster and @dbaron I’ve been working on it for the past few months, and next week we’ll be presenting our work at the CSSWG F2F meeting.

I built a thing this week (with the help of Antigravity): a CSS Typed OM polyfill.

It currently passes 12588 of WPT's 12942 CSS Typed OM test, which is more than any browser!

Mid May, at this year’s Google I/O, Una and I gave a talk “What’s new in Web UI” live at Shoreline in the Chrome tent.

New in Chrome DevTools in Chrome 151 (which goes stable mid July):

The specificity bubble can now show you a breakdown of how the specificity was calculated.

Big thank you and congrats to januschka.com for contributing this to Chromium 👏

@marcthiele “I love the shape of Bramus’ talk. […] It goes looking for the edge on purpose, shows you the failures along the way, and comes back with both a real tool and a grin. That is about as beyond tellerrand as a talk about a CSS specification can get. ;)”

Thank you, Marc.

I am moved by the kind words Marc had to say about my talk. It proves, again, that he is one of the kindest and warmest persons I have ever met.

It’s video release week!

After the recording from All Day Hey and CSS Day before, the recording from Beyond Tellerrand is now available too.

While the talk is technically the same, the flow of it as well as its contents are quite different from those other renditions, so you might want to give this one a watch as well.

With #GoogleIOConnect Berlin just last week, my pre-summer conference season has come to a close.

In 2 months I did 4 Meetups, 5 Conferences, and 1 Team Summit … while doing some _actual work_ in between 🫨

This week I’m tying up some loose ends, and after that I’ll be taking some time off 🏝️

#ChromeDevRel

In May I spoke at the 10th (and final 😔) edition All Day Hey! in Leeds, UK. I opened the conference with a talk on View Transitions.

Back in April I went to Beyond Tellerrand in Düsseldorf. I initially planned on going as an attendee, but when organizer Marc asked me to speak I couldn’t say no …
