Made in Cincy


wysihtml5x is an extended and less strict approach on xing/wysihtml5 open source rich text editor based on HTML5 technology. The code is completely library agnostic: No jQuery, Prototype or similar is required.

This project was initiated and is supported by the XING AG. Thanks!


Extended features not present in xing/wysihtml5:

The rich text editing interface is supported in IE8+, FF 3.5+, Safari 4+, Safari on iOS 5+, Opera 11+ and Chrome. Graceful Degradation: Users with other browsers will see the textarea and are still able to write plain HTML by themselves.
