How do we know if img is the html's img tag or something else? We could issue warnings only if we know that a CSS is linked from an HTML document» Fair question, although we do know that the main usage of CSS is to style HTML and SVG, and that could remain a decent assumption. Do we still have a list of html elements? 23421 2 ot 2009-02-03 20:04:25 +0000 I somewhat miraculously managed to add the warning for the general case, but have not yet found how/where I can determine which element selector is applicable. Any pointer? For reference, the code is in http://dev.w3.org/cvsweb/2002/css-validator/org/w3c/css/properties/css1/Css1Style.java (look for findConflicts ) 23450 3 624 ot 2009-02-04 14:50:21 +0000 Created attachment 624 test case 23451 4 ot 2009-02-04 15:05:36 +0000 http://lists.w3.org/Archives/Public/www-validator-cvs/2009Feb/0050.html seems to have done the trick - the test case validates with a single warning for the <p> but not the <img> selector, which has intrinsic width. 624 2009-02-04 14:50:21 +0000 2009-02-04 14:50:21 +0000 test case floatnowidth.css text/css 191 ot LyogZm9yIGZsb2F0ZWQgZWxlbWVudHMgd2l0aCBubyBpbnRyaW5zaWMgd2lkdGgsIGlzc3VlIGEg d2FybmluZyBpZiBubyB3aWR0aCBpcyBnaXZlbiAqLwovKiB0aGlzIHN0eWxlc2hlZXQgc2hvdWxk IHZhbGlkYXRlIHdpdGggb25lIHdhcm5pbmcgKi8KaW1nCnsKICBmbG9hdDogcmlnaHQ7Cn0KCnAK ewogIGZsb2F0OiByaWdodDsKfQo=
