Make an IE CSS hack pass W3C CSS validator Authored by aklapper on Mar 24 2025, 11:11.
Details
The W3C CSS validator throws Value Error : margin-top Too many values or values are not recognized : 1px \9. It does not complain about 1px\9. See https://stackoverflow.com/questions/8004765/what-is-the-meaning-of-9-in-this-width-property-value-declaration, https://stackoverflow.com/questions/18907131/detecting-ie-version-using-css-capability-feature-detection, https://www.w3.org/TR/CSS2/syndata.html#characters Paste core.pkg.css into https://jigsaw.w3.org/css-validator/. Optionally, find some ancient Internet Explorer version and run it (I did not).

Event TimelineComment Actions Thanks for this patch! Kind reminder: if you touched CSS or JavaScript, please remember to also run this: ./bin/celerity map ⚙️ Thanks! Bip bop I'm a bot - helping for T15209 Comment Actions I've tested in my console: body { margin-top: 100px \9; } And: body { margin-top: 100px\9; } And both are completely ignored in my browser webs Firefox and Chromium. So this is not supposed to cause regressions there. |
