I need to share styles across multiple Polymer elements. Is it acceptable to create a \"styles.html\" file and then import that into my different elements or would this star
As of Polymer 1.1, the polymer project authors recommend creating and importing a style module to address this issue.
To share style declarations between elements, you can package a set of style declarations inside a element. In this section, a holding styles is called a style module for convenience.
A style module declares a named set of style rules that can be imported into an element definition, or into a custom-style element.
