title: edit css style of an element with a space in its class name
body: <p>I'm creating a tumblr them and I have to write an external CSS file but I am having trouble editing the css style of the post elements. </p>
  
  <p>This its structure:</p>
  
  <pre><code>&lt;li class="post quote"&gt;
      {other code}
  &lt;/li&gt;
  </code></pre>
  
  <p><br>
  The problem is that the class name has a space in it.<br><br>
  How would I create a CSS class to access this? And yes, I know I can just put a style attribute in the element tag but I was kind of hoping for another option.</p>
