Cross-Browser.com is the home of X - a cross-browser Javascript library, and many demos, applications, articles and documentation.
The X core is designed to work with all browsers, Object-detection instead of browser-detection is used exclusively. Currently, I'm testing with the following browsers. X has been tested by others on a wide variety of platforms.
Win7 (Home): IE 9.
WinXP (SP3): Chrome 3.0.195.38, Firefox 3.5.5, IE 7 & 8, Opera 10.60 and Safari 4.0.3.
Linux (Ubuntu 9.10): Chrome 4.0.249.43 and FireFox 3.5.7.
This site and all its javascript were developed with UltraEdit, a most excellent programmer's editor.
