With IE9 in development and Opera 10.5 released, CSS3 is a few steps away from being supported by all modern browsers. But users may take a while to upgrade, and responsible developers will support legacy browsers for years to come.
For some, cross-browser development means making websites that look exactly the same in all browsers. But if developers continue to cater websites to inadequate browsers such as IE6, then they’re just holding back modern browsers from performing to their potential.
Graceful degradation is not about allowing websites to look bad in older browsers, but about making them look great in modern ones. It means taking advantage of CSS3’s useful features to progressively enhance web pages for the vast majority of users.
