title: How can I select an element with multiple classes in CSS?
body: <p>What would be the proper CSS selector to target the following tag:</p>
  
  <pre><code>&lt;nav class="twelve-col col main-menu"&gt;
  </code></pre>
  
  <p>Would the proper selector just be:</p>
  
  <pre class="lang-css prettyprint-override"><code>.twelve-col col main-menu {
  }
  </code></pre>
