Builder.com: Building for the 5.0 browsers

“Both Internet Explorer 5.0 and Navigator 5.0, currently known
as Gecko, are promised by the respective browsermakers to be stable
and well tested. More importantly, the alphabet soup of client-side
technologies has had time to mature into standards that both
companies have agreed to fully support.”

“… the fact that both companies are aiming at the same
standards is a good sign.”

“Nevertheless, for your site to get the most out of the new
browsers, you need to know which new features they share, as well
as each one’s proprietary extras.”
