Cross-Browser Rich Text Editor (RTE)

This code is licensed under a Creative Commons License (as of 5/15/2006).

The Cross-Browser Rich Text Editor (RTE) is based on the designMode() functionality introduced in Internet Explorer 5, and implemented in Mozilla 1.3+ using the Mozilla Rich Text Editing API.
Features

The Cross-Browser Rich Text Editor now includes table support (as of 2/10/2005) as well as an option to generate xhtml-compliant code (as of 2/24/2005).

Requires: IE5.5+/Mozilla 1.3+/Firefox 0.6.1+/Netscape 7.1+/Mac Safari 1.3+/Opera 9+, or any other browser that fully supports designMode() for rich-text features. All other browsers will display a standard textarea box instead.
