How do you add stylesheets to JSDOM

I am currently working on a project that requires me to have computed styles send to the browser via JSDOM. I am currently looking for a way to inject some basic CSS into JSDOM so that it could compute the correct inline style (Yes I know that's bad).

From what I have found out I can use JSDOM Level 2, but from there I can't find any documentation on how to inject the styles.

This is what I have so far;

    var document = jsdom.jsdom('<!DOCTYPE html><html><head></head><body id="abody" ></body></html>', jsdom.level(2, 'style'), {
        features : {
            FetchExternalResources : ['script', 'css'],
            QuerySelector : true
        }
    });

I have been inserting the css into the head tag but to no avail. And I know I could be doing the above code wrong as well.

Any help would be great.

Well, this is going to sounds kinda dumb but this is what I did:

    var path = require('path');
    var fs = require('fs');
    var mainCss = fs.readFileSync(path.normalize(__dirname + "web_main.css"), 'utf8');
    var document = jsdom.jsdom('<!DOCTYPE html><html><meta http-equiv="content-type" content="text/html; charset=utf-8"><head></head><body id="abody" ></body></html>', jsdom.level(3, 'index'), {
        features : {
            FetchExternalResources : ['script', 'css'],
            QuerySelector : true
        }
    });     
    var window = document.createWindow();
    var head = document.getElementsByTagName('head')[0];
    style = document.createElement("style");
    style.type = 'text/css';
    style.innerHTML = mainCss;
    head.appendChild(style);

So basically all I changed was moving the level to 3 index, and instead of directly having it in the starting html, I appended it afterwards.

Its pretty simple and I hope it helps someone else out.
