Note, that Brian Wilson use different references. I marked to some NN 3.x series supported elements the NN 4.x series as the last browser series, which support them, because Netscape tries today more than before support official recommendations. Microsoft brings to the next version of MS Internet Explorer much new proprietary features. I appreciate very much MS in developing new web technology, but I resist the way, how Microsoft accomplishes new implementations in new browsers, for example in MS IE 5.5 . Note 1 .
Some proprietary elements have extremely limited support.
Note 2 . Also colors value keywords are a partially proprietary. Read the page about Color value keywords . I recommend to use standard features. CSS-implementations are however more or less buggy.
