  <desc>Selects even elements, zero-indexed.  See also <a href="/Selectors/odd/">odd</a>.</desc>
  <longdesc>
    <p>In particular, note that the <em>0-based indexing</em> means that, counter-intuitively, <code>:even</code> selects the first element, third element, and so on within the matched set.</p>
