title: Multiple dots/periods in CSS
body: <p>Can one of you CSS experts explain this designator (if that's even what you'd call it) to me? I understand the contents, just not the a.button.gold.  Two dots?</p>
  
  <pre><code>a.button.gold{
  background-color: #b9972f;
  }
  </code></pre>
  
  <p>I am trying to modify a couple of styles on a Wordpress theme and would have a lot more success with it, if I could figure out what is currently happening.
  Thanks </p>
