Hi Team, While looking into Blink source and then comparing it WebKit, I noticed that we don't have 'direction' (of HTML Marquee - I know I know) as case sensitive selector. I was not able to find Web-spec reference, so I went to 'Anne' (HTML Champion), if he can help and he did. Web-Spec: https://html.spec.whatwg.org/#case-sensitivity-of-selectors WebKit Source: https://github.com/WebKit/WebKit/blob/b10105f3d6b7e01e12f1c141a0aebc023f2324c9/Source/WebCore/html/HTMLDocument.cpp#L184 We need to add direction (&directionAttr,) in alphabetical order. Failing Test (again thanks to Anne) - data:text/html,<style>marquee[direction=left]{background:lime}</style><marquee%20direction=LEFT>BLAH</marquee> ^ We don't get 'lime' color but Blink does. Just raising so we can fix it. @Anne - Thanks for your help as always. Appreciate it. Thanks!
Probably it would be good to add a WPT test for it too. Maybe in https://wpt.fyi/results/css/selectors/attribute-selectors/attribute-case/syntax.html
