This page contains some samples to check current browsers for up-to-date Internet technology, especially CSS properties.
All checks are valid within the HTML 4 and CSS 2 standards from 1997. The examples contain an XHTML 1.1 doctype, because IE7 implements better CSS-rendering within that. Beside that, they completely work with older doctypes the same.
Testing browsers:
Mozilla Firefox 1.5 (Windows und Linux)
Internet Explorer 6 (Windows)
Internet Explorer 7 beta 2 preview (Windows)
Konqueror 3.5.1 (Linux)
Opera 8.51 (Windows und Linux)
gtkhtml 2.6.3
