How to make syntax/editor highlight for textarea in Chrome?

Question

Google Chrome

There is an urgent need for syntax highlighting and simple sort-editing features for arbitrary textarea.
I explain the situation:

Here is such a hell (forgive me if someone recognized Joomla 1.5 and mod_html in this). Considering that there are about a dozen such modules (well, there is no such need and opportunity to do it differently in the foreseeable future), and html / css / js are mixed in them, it’s, frankly, not easy to understand the text without highlighting. Often, I just copy the code to NPP, and then return it back.
In this regard, the thought has been haunting me for a long time: is there (I didn’t find it myself) an extension for Chrome that would implement a simple editor, at least with highlighting and search replacement?

Answer 2

swoop I understand that in textarea it is impossible to shine syntax and other delights of the editor. this is done by divs and javascript (editor emulation or something like that)

Answer 3

There is codemirror.net but it has extensions for browsers, in my opinion. So you have to "collective farm", or do, for example, a user script.
