I'm using adapt.js for the first time on a project. I have a range 0 to 720, I want to load a mobile.css file as well as a second css file, we'll call it style.css. Is this possible? Are there any work arounds? I tried this but it didn't work, as expected.

```
var ADAPT_CONFIG = {
    path: 'css/',

    dynamic: true,

    range: [
        '0px    to 720px  = style.css',
        '0px    to 720px  = mobile.css',
        '720px            = 720.css'
    ]
};

```
