title: Is there a CSS selector for element without any class?
body: <p>Is there a CSS selector for element without any class? For example in HTML</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;section&gt;Section A&lt;/section&gt;
  &lt;section class="special"&gt;Section B&lt;/section&gt;
  &lt;section class=""&gt;Section C&lt;/section&gt;
  </code></pre>
  
  <p>I would like to select Section A (or maybe Section A and Section C, it does not matter that much), by saying something like</p>
  
  <pre><code>section:not(.*) { color: gray } 
  </code></pre>
  
  <p>I understand that I could define it to section and reset it back in all particular classes, like in </p>
  
  <pre><code>section { color: gray } 
  section.special { color: black } 
  </code></pre>
  
  <p>but this is not what I want, because it is not very manageable once the styles get complex and in some cases it is hard to do the "reset" properly (of course not in this simplified example).</p>
