title: (S)CSS React element selector
body: <p>I'm looking for a simple way to select an existing react element in my css. I've tried searching it but only found confusing answers about tons of libraries I can use, and none seemed to fit what I'm trying to do.</p>
  
  <p>I want to have a regular <code>.scss</code> file, where if I have the react element called <code>Foo</code>, I can do something like this:</p>
  
  <pre><code>Foo {
      color: red;
  }
  </code></pre>
  
  <p>This would be great because I could continue with <code>.scss</code> files which I like, and could select components. How can I do this (or achieve similar behaviour)?</p>
  
  <p><em>Notice that I'm not the one creating the element so I can't just apply a class to all of them.</em></p>
