I would like to create an editable "textarea" with text highlighting (e.g. different colours, bold) and I am not interested in backward compatibility with old (and meybe current) browsers.
It isn't a code editor, but something similar. So it is really different from CkEditor, because the content should appear formatted to the user, but I don't want to add HTML tags to the text. I only need to change the appearances, not to modify the text!
I read that Bespin uses canvas. Is that the right and most effective solution?
