      🎉 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 … 🤯

      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.

          But how would you handle the fallback for browsers that don't support SVG favicon?🤔

          If you need a fallback, then definitely use <link rel=icon>. I just won’t be doing that:https://twitter.com/mathias/status/1196820845915705344 …

          IMHO, a favicon is non-essential and falls under progressive enhancement. Once all major browsers I care about support SVG favicons (January 15, 2020), I’ll happily go SVG-favicon-only.

          OK. Personally, I’d avoid it, because you’d need a custom setup for your server (e.g. npx serve doesn’t work out of the box). And working locally with the file (via SVG editors etc.) becomes more complicated.

          But avoiding one request is indeed a nice benefit.

          "file extensions don't matter on the web" How exactly does YOUR server determine the MIME type of a file when serving it?
