1, CSS Comment Bug
In IE5.0 (Window && Mac) and previous versions, it cannot be identified for the following CSS comments.
# CommentImmediatelyAfterSelector / * * / {Color: # f00;
2, selector
IE does not support the syntax of most selectors in CSS2 (http://www.w3.org/tr/rec-css2/selector.html#attribute-selectors)
For example, use attribute selectors
P [Id] {color: # 0f0;}
Or child element selector
P> span {color: # 00f;}
