Dynamically load stylesheets

You should look into asychronously loading assets, such as the famous google-analytics code. You can load external stylesheets using Javascript.

JavaScript

(function(){
  var styles = document.createElement('link');
  styles.rel = 'stylesheet';
  styles.type = 'text/css';
  styles.media = 'screen';
  styles.href = 'path/to/css/file';
  document.getElementsByTagName('head')[0].appendChild(styles);
})();

Lines 1 and 7 create a new scope for variables such that local variables do not collide or override with globally scoped variables. It isn't necessary just a best practice. This solution also assumes you have a <head> tag in your html.
