YES, Dark Mode Toggles _should_ be a browser feature.

I wrote about this before: https://brm.us/dark-mode-override

If you liked Jelle's talk and want to revisit, I have a small section on value processing on my blog (as part of a post on IACVT): https://brm.us/value-processing

Dropped my stuff off at the #cssday venue. Like you do. Totally normal.

A PSA for the #cssday attendees:

It is perfectly safe to attend this year. Left my CSS Flamethrower at home. Apparently they don’t want me to burn the venue down.

But no worries. I am only bringing an oscilloscope - it been repaired since it exploded last year - and lasers. Perfectly safe.

Anyway... the talk is done. Rehearsed a couple of times. Happy with the pace and I still have 10 - 15 minutes left for the demos that I have planned and Q&A.

Panic over.

Every time I decide to write a talk I underestimate the time I need. I do have a rough idea, but there is this whole period of me just making random slides. Sometimes weeks.

Then suddenly I am happy. Build the rest of the talk in a day or two. Way too long. Cut in half. And it just fits together.

I haven't yet made plans for speaking at conferences this fall – limited time and writing another talk kind of felt too much...

Now that the CSS Day talk is ready, I really think the CSS DOOM chapter would work really well as a standalone talk.

Hit me up in my DMs – love to talk about CSS DOOM

This weekend was full-panic mode for #cssday as I had not a single slide or even an outline. And the conference is next week.

It took a couple of days, but last night I finished it and thought I could relax again.

Did a full run-through today and I’m about 15 minutes long. Back to panic mode.
