title: Is a <style> tag inside a .css include file tolerated?
body: <p>In a project, We have a <code>&lt;style&gt;</code> tag in the start of a CSS file (Because some editors don't show CSS highlighting otherwise):</p>
  
  <pre><code>&lt;style&gt;
  body {
    ...
  }
  ....
  </code></pre>
  
  <p>I know, this is <a href="http://imgur.com/a/GHjbp" rel="nofollow">wrong inside a CSS file</a>, because this would usually be the notation for inline CSS inside HTML but it seems also to be tolerated (at least by Firefox 49) if the <code>&lt;style&gt;</code> tag is set <strong>inside the CSS include  file</strong> right at the start.</p>
  
  <p>I Try to find out, If I have to correct this in our Project or leave it as it is, which I would prefer if it is largely tolerated (at least by Firefox since version 26)</p>
