    🎉 Chrome now supports SVG favicons! https://chromium-review.googlesource.com/c/chromium/src/+/1541185 … Pro tip: you don’t need any HTML to declare a favicon. Host your SVG file at /favicon.ico and serve it with the correct MIME type (image/svg+xml). https://mathiasbynens.be/notes/rel-shortcut-icon … 🤯

        Since you can put CSS in an SVG, would a `prefers-color-scheme: dark` media query be enough for dark mode support?

        Test case: https://numerous-sulfur.glitch.me  The media query is ignored. @jaffathecake had an interesting write-up on how media queries behave in SVG across browsers: https://jakearchibald.com/2016/svg-media-queries/ … This behavior seems to follow from that.

        Genuine question: Pro tip or a hack that happens to work? Doesn’t seem like a best practice to me(?)

        Which part exactly? All browsers request /favicon.ico by default (see link in tweet for my old write-up). And file extensions don’t matter on the web; MIME types do. I see nothing wrong with this.

        I didn't even realise Chrome didn't support it. It was a no-brainer when I implemented support for them in @polypane.

        The lack of support bothered me everytime I browsed to a @WHATWG spec. Well, not anymore! 👍

        Is the recommendation to use server-side browser sniffing to know when SVG is supported, or is there a clean way to statically return ICO/PNG/SVG in a way that lets the browser choose?

        The static solution is to use <link rel="icon" type="…">. For a server-side solution, browser sniffing seems overkill for this purpose. If we could tweak the Accept header Chrome sends for such requests, it might be easier: https://bugs.chromium.org/p/chromium/issues/detail?id=294179#c73 …

        What I dislike is that ICO file format is originally a container for BMP and PNG. So having a favicon.ico served with mime-type image/svg+xml sounds semantically wrong to me ^^

        Both URLs in my tweet don't have any extensions at all. The same goes for the Twitter URL of this very tweet. Is that semantically wrong too? It's just a URL. Extensions don't matter on the web; MIME types do.
