In this column we discussed text rollovers, made possible by Internet Explorer 4.0 (and Navigator 4.0x) innovations. Such rollovers are already being used by the Web's most popular sites, including CNET. We showed you how to apply these effects to an entire page, and even to an entire site, without much pain and maintenance.
