title: Event for the load-end of dynamically added CSS files through innerHTML
body: <p>I use jQuery (which seems to use a glorified form of innerHTML document writing), to add a piece of HTML to the DOM:</p>
  
  <pre><code>    $newElem=$(HTML).appendTo($container);
  </code></pre>
  
  <p>The said HTML piece contains CSS links, which seem to load async. Images also load async.</p>
  
  <p>I need some form of <code>load</code> event similar to <code>window.load</code> when async content is done fetching AND done parsing (i.e. CSS), because based on that I trigger a container resize/rearrange function, and sizing obviously depends on CSS, async images (and even async fonts but this last point is not an immediate concern for me). So how to get a proper <code>load</code> event for the DOM-added HTML?</p>
