title: Can StencilJS component use external theming?
body: <p>I'm trying out StencilJS for creating reusable web components for multiple projects that I'm working on. 
  But I'm having a hard time to inherit the color themes from my main applications to, let's say, my Stencil button component.
  Example: I want to use different primary and secondary coloring for my applications that applies on my Stencil components like a primary colored button. But how do I manage to do so? I'm using sass styling and have the primary variable locally set in my Stencil project with my theme. But I don't know how to import external sass/css files after compilation.</p>
  
  <pre><code>&lt;my-button color="primary"&gt;This is a primary button&lt;/my-button&gt;
  </code></pre>
