Trying to format - need help

Hi, I placed the CodeMirror like this:

var myCodeMirror = CodeMirror.fromTextArea(document.getElementById(‘txt1’), {
mode : ‘mixedMode’
, lineNumbers : true
, readOnly : true })

and you can see it here:

How do I format it, like green bars, width, height, and formating?
It just shows all black.

Help plz. I read the docs 2x.
Cheers,
Vic

There is no mode called mixedMode in the distribution, and it looks like you’re not loading any modes at all on that page.

What mode should I use for html?
The list of modes is all caps, is that the format?
What do you mean - ‘load’?

How do I size height and width?
And how do I add greenbar?

cheers,
Vic
