How to load up CSS files using Javascript?

Question

Is it possible to import css stylesheets into a html page using Javascript? If so, how can it be done?

P.S the javascript will be hosted on my site, but I want users

Here's a way with jQuery's element creation method (my preference) and with callback onLoad:

var css = $("", {
  "rel" : "stylesheet",
  "type" :  "text/css",
  "href" : "style.css"
})[0];

css.onload = function(){
  console.log("CSS IN IFRAME LOADED");
};

document
  .getElementsByTagName("head")[0]
  .appendChild(css);
