title: Targeting an element with only one class value
body: <p>If I have two elements like this</p>
  
  <pre><code>&lt;div class="one two three"&gt;&lt;/div&gt;
  &lt;div class="one"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>And I want to grab the div that has only the <code>"one"</code> classname.</p>
  
  <p>I know I can do this like this:</p>
  
  <pre><code>div[class="one"] 
  </code></pre>
  
  <p>because if I do <code>div.one</code> it applies to both, </p>
  
  <p>is there any other way to get the element with just the specified classname?  </p>
  
  <p>edit - the goal being to shorten the selector character count</p>
