# CSS Shadow Parts

The first major update to the Shadow DOM API, it will (finally) allow you to expose certain parts of the shadow root to make them "styleable" from the main DOM.

<!-- PSEUDO CODE -->
<my-element>
  #shadow-root
    <div part="header">...</div>
    <div>...</div> /* not styleable
</my-element>

Now we have access to some new pseudo-selectors...
