title: Should I use the same selector twice in CSS?
body: <p>Which of the following would be considered best (i.e. better) practice?</p>
  
  <pre><code>#anElement {
      font-size:1em;
      color:white;
  }
  
  /* other stuff */
  
  #anElement {
      width:100px;
      margin-bottom:10px;
  }
  </code></pre>
  
  <p>or</p>
  
  <pre><code>#anElement {
      background-color:black;
      color:white;
      font-size:1em;
      margin-bottom:10px;
  }
  </code></pre>
  
  <p>In other words: should I <em>dry</em> the CSS as much as possible or should I work on typography and general layout separately, maybe even in separate files?</p>
