title: What CSP is safer - style-src 'none' or style-src 'unsafe-inline'
body: <p>I am struggling to fully understand <code>style-src 'none'</code>. Based on the naming, it sounds like it would be restrictive or does it mean that there are no rules and you can do whatever you want?</p>
  <p>Same question for <code>script-src 'none'</code> in the unlikely situation where it acts differently.</p>
  <p>Side-note - what is the best CSP if you are using the library <code>styled-components</code> (everything is injected as inline with this library)?</p>
  <p>EDIT:</p>
  <p>I have read before the description of <code>none</code> from mdn.</p>
  <pre><code>'none'
  Refers to the empty set; that is, no URLs match. The single quotes are required.
  </code></pre>
  <p>What does this mean? Does this mean that it does not block styles/scripts or the opposite?</p>
