Pull page styles into Polymer custom elements.
Add eee-c/apply-author-styles to Bower dependencies:
$ bower install --save eee-c/apply-author-styles
Then import and use the <apply-author-styles> tag:
<link rel="import"
href="../bower_components/apply-author-styles/apply-author-styles.html">
<polymer-element name="x-pizza">
<template>
<apply-author-styles></apply-author-styles>
<!-- ... -->
</template>
<script src="x_pizza.js"></script>
</polymer-element>That's all there is to it. Styles defined in the <head> of the containing document will now be applied to the Polymer element. Yay!
