I don\'t want to use styles from style.css, so I decided to remove style.css from DOM. This work just fine in Firefox and IE8, but not in IE6:
$(\"LINK[href=
Perhaps it's something strange IE6 does to URL in the href attribute? Try something like:
$("LINK[href*='style.css']").remove();
(i.e. check whether the href value contains "style.css")
It's just a guess, however. If that doesn't work, I recommend checking the JQuery documentation closely on the subject of attribute selectors and the remove method.
Also keep in mind that it's also not impossible that it's in fact a bug. (IE6 in general causes lots of issues involving JavaScript and DOM manipulation, among other things.)
