title: CSS "not" selector does not work
body: <p>I can not put two different rule in the "not" selector
  Example:</p>
  
  <p>This code works:</p>
  
  <pre><code>input:not([type=submit]) {
    // Styling here
  }
  </code></pre>
  
  <p>but this code does not work:</p>
  
  <pre><code>input:not([type=submit], [type=reset]) {
    // Styling here
  }
  </code></pre>
  
  <p>Why the second code does not work?</p>
