Shadow DOM

I’ve linked to articles about web components and shadow DOM before but I cannot help myself. It is awesome! For most teams it might not be something you can use today.

Anyway, this article from Monica, who is a member of the Polymer team, is a great article about shadow DOM and the benefits it gives.
