I just want to "report" that the new W3C's "CSS Validator" (i.e. with "new" I mean the updated interface and apparently also the code/algorithm) doesn't show warnings anymore in its results ... For instance, look at the results for my website's main.css stylesheet-file here: http://jigsaw.w3.org/.../main.css (or alternative link: http://jigsaw.w3.org/...main.css&warning=1&profile=css21&usermedium=all) or for the root.css stylesheet-file here: http://jigsaw.w3.org/.../root.css (or alternative link: http://jigsaw.w3.org/...root.css&warning=1&profile=css21&usermedium=all) Now look here how the results looked before this change: http://tadej-ivan.50webs.com/legal/css.html with warnings and all. tayiper
