title: What does !default in a css property value mean?
body: <p>The twitter bootstrap code has a lot of CSS properties with a <code>!default</code> at the end.</p>
  
  <p>E.g.</p>
  
  <pre><code>p {
    color: white !default;
  }
  </code></pre>
  
  <p>What does <code>!default</code> do?</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>My bad for not being clear. I am using the SASS part of Bootstrap.</p>
