title: How do I change Ionic 4's ion-range pin font and formatting?
body: <p>As an example, I tried this in my global.scss file:</p>
  
  <pre><code>.range-pin {
    color: white;
    font-family: sans-serif;
  
    &amp;after:{
      content: " %";
    }
  }
  </code></pre>
  
  <p>But this has no effect. I'm sure this has something to do with shadow root but I'm not sure what the right thing to do is here. Adding <code>ion-range .range-pin</code> to be more specific doesn't help either. How do I achieve this change?</p>
