That was neat, eh? Of course, if you were using Internet Exploder, nothing much really happened. Another disadvantage is that you have to figure out how much space the texts are going to use. A final major disadvantage is that the previous example doesn't work in Netscape 4.76 (and perhaps other versions...).
Since Netscape 4 doesn't dynamically reflow content (except for layers etc.) little else can be done. Netscape 6 promises more, although I haven't checked it out yet, as of this writing.
