Twelve years ago, I started a draft for an article. I never published it: there were a few cross-browser issues, and the idea was raw and unpolished. I have many drafts like this in my archives. Sometimes, something new interacts with one of these older ideas and leads to something interesting. This article is about one such case: a hacky technique that allows us to pass some data from CSS to SVG and use it to adjust colors or almost anything else.
For me, 2025 was a much less productive year than 2024. A mix of industry and world frustrations, personal issues, and just certain people being mean — all of that made me live on borrowed spoons for most of the year. This post won’t have any of that, of course, but will contain a roundup of everything I wrote about CSS, so if you missed something — it is a good way to catch up!
Chrome currently has an experimental implementation of custom CSS functions in its Canary version. In a small series of blog posts, I’ll write about a few things I found interesting in the current prototype implementations of functions and conditions. This post is about one feature of custom functions that I will likely use all the time, but which might not be obvious at the first glance.
