Is it possible to select the last n items with nth-child?

nth-last-child sounds like it was specifically designed to solve this problem, so I doubt whether there is a more compatible alternative. Support looks pretty decent, though.

This will select the last two iems of a list:

li:nth-last-child(-n+2) {color:red;}

<ul>
  <li>fred</li>
  <li>fred</li>
  <li>fred</li>
  <li>fred</li>
  <li>fred</li>
  <li>fred</li>
  <li>fred</li>
  <li>fred</li>
</ul>
