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

text-decoration:blink is optional due to W3C. text-shadow has been removed in CSS 2.1, but is valid due to CSS 2.0.

All examples are valid W3C HTML/XHTML and CSS.
Valid HTML 4.01! Valid CSS!
