title: Using nth-child to style item 4 and onwards
body: <p>I have a list item where I'd like the 4th item and onwards to have a different <code>background-color</code>.</p>
  
  <p>I've tried the following:</p>
  
  <pre><code>li:nth-child(4) { background-color:blue; }
  </code></pre>
  
  <p>This styles only the 4th item. I then tried the following in the hope that it would style 4th item and onwards, but it didn't work:</p>
  
  <pre><code>li:nth-child(4+) { background-color:blue; }
  </code></pre>
  
  <p>How can I get this to work without having to specify 4th, 5th, 6th, 7th etc...?</p>
