Making single color SVG icons work in dark mode

In a project I work on, we had a couple of buttons that consisted of just icons (with visually hidden help text). The awesome QA engineer I worked with, found some of those did not show up in dark mode, which rendered the buttons unusable for users of that mode. Using inline SVGs with currentColor fixed the issue.

This is neat. I’m not yet convinced of how wise it is for an operating system preference (dark mode) to be exposed via its browser, but I can see the logic. And I approve of the fact that CSS can be used to interrogate it. But really what I like about this article is the demonstration of how currentColor propogates even into inline SVGs: that’s neat, and a good observation by the author of the linked article.
