title: Error GET http://localhost:4200/styles.css but I'm able to use these styles. Whats the deal?
body: <p>I'm receiving an error in my angular 2 project where in the chrome developer tools console there is a message saying GET <a href="http://localhost:4200/styles.css" rel="noreferrer">http://localhost:4200/styles.css</a> with a red x to the left of it. I'm able to use these styles though so what's the deal?</p>
  
  <p>This is my index.html file:</p>
  
  <pre><code>&lt;!doctype html&gt;
  &lt;html&gt;
  &lt;head&gt;
    &lt;meta charset="utf-8"&gt;
    &lt;title&gt;Scorekeeper&lt;/title&gt;
