title: What is the third value in CSS padding?
body: <p>I am playing around with the <a href="http://lessframework.com/" rel="noreferrer">Less Framework 3</a> and I saw this line in the css:</p>
  
  <pre><code>body {
      padding: 60px 42px 0;
      width: 396px;
  }
  </code></pre>
  
  <p>what does <code>padding: 0</code> do?</p>
  
  <p>This does not look like  normal css shorthand,  and <code>top-right-bottom</code> seems weird.</p>
