title: Dynamically add css to page via javascript
body: <p>I'm making a widget that will be added to external websites, and I have made a page that generates css for them to style it (text color, background color, font size, etc). I end up with a textarea filled with css for them to copy/paste to their website.</p>
  
  <p>Is there a way to add this css to the current page in order to have a live preview?</p>
