WYSIWYM (what you see is what you mean)

What is it?

WYSIWYM is not WYSIWYG. Well actually it is. But it is more geared toward using stylesheet than inline-css.

Currently I am struggling to master wymeditor.

I'll be using this for every site I made. Unless there's a higher authority that says otherwise.

The question is, how to make it works like LibreOffice.
