Today I learned that the default CSS stylesheets of browser engines are nicely available for reading.
Default `html.css` implementations on different browser engines:
- Chromium https://source.chromium.org/chromium/chromium/src/+/main:third_party/blink/renderer/core/html/resources/html.css;bpv=1
- Firefox https://searchfox.org/mozilla-central/source/layout/style/res/html.css
- WebKit https://trac.webkit.org/browser/trunk/Source/WebCore/css/html.css
Found via Thomas Steiner‘s blog post: https://web.dev/color-scheme/
(Edited 2023-09-11 with a much more up-to-date link to Chromium stylesheet.)
@autiomaa I keep seeing people link to this 8-year old "Chromium" version from back when Blink was a separate repository. The actual Chromium one is in https://source.chromium.org/chromium/chromium/src/+/main:third_party/blink/renderer/core/html/resources/html.css .
@domenic Updated the post. Thank you again for the up-to-date URL. 😊
Old was truly ancient...
@domenic Thanks, I need to update that post. Kind of odd, since I found those originally from a Chrome developer's blog post. Apparently mistakes happen.
