CSS can coexist with Netscape 4!
Recently, a reader posted www.realworldstyle.com on my comments section, informing me that you can do 3 column layouts, with footers, in XHTML and CSS that work with NN4. I was skeptical. But indeed, it works. I don’t understand exactly why, but this is a God send to those who have to make things compatible in NN4. (thanks: Roger Waggoner)
