Calling css file from javascript

bazcaz

I am writing some javascript for an extension to Thunderbird , and I need to change the font colour of some text to different colours depending on certain calculations made in the javascript.

What I am wondering is there a way of calling the css file that holds the code for changing the font colour directly from the javascript something like

if(priority==6)
{
//call css file that changes font colour to red
}

You may find this of use. It gives examples of changing css rules. This would do what you want to do.
Also look out for CSS objects.

You could also consider using the DOM to rewrite the HTML using getElementById methods

If you're building an extension, why not just manipulate the DOM?

I am not sure exactly how to manipulate the DOM I mean I have a Dom inspector extension installed in thunderbird but I am not sure exactly how to use it , I am trying to change the font colour of subject lines in inbox

The thing is I have a little bit of code in a css file that does exactly what I want I just want to know if there is anyway of just called my extension.css file if a certain condition is met in the javascript
