Minimalist WYSIWYG Rich Text Editor – SlimWhizzy

SlimWhizzy is a super small (less than 1kb) JavaScript library which makes use of execCommand() to create a minimal, clean WYSIWYG Rich Text Editor for a content editable element.

How to use it:

Use an iconic font of your choice for the editor icons.
