title: Material Design Typography and Metric Rules in Polymer
body: <p>My question is rather simple: What is the recommended way to implement the typographic and metric rules of Material Design (<a href="http://www.google.com/design/spec/material-design/introduction.html">http://www.google.com/design/spec/material-design/introduction.html</a>) in a Polymer application? For example, how to implement the units sp and dp in CSS?</p>
  
  <p>Is there an official CSS file I could include? I am also not sure whether the Core and the Paper Elements of Polymer all conform to the general rules of Material Design. It says that the Topeka application bundled with Polymer is an example of Material Design. However, I haven't understood this by reading its source and in particular its style sheets. For example, the profile screen (<a href="https://github.com/Polymer/topeka-elements/blob/master/topeka-profile.html">https://github.com/Polymer/topeka-elements/blob/master/topeka-profile.html</a>) does not follow all the metric rules, does it? (Or am I completely mistaken?)</p>
