title: How to disable text selection highlighting
body: <p>For anchors that act like buttons (for example, the buttons on the sidebar of this Stack Overflow page titled <em>Questions</em>, <em>Tags</em>, and <em>Users</em>) or tabs, is there a CSS standard way to disable the highlighting effect if the user accidentally selects the text?</p>
  <p>I realize that this could be done with JavaScript and a little googling yielded the Mozilla-only <code>-moz-user-select</code> option.</p>
  <p>Is there a standard-compliant way to accomplish this with CSS, and if not, what is the &quot;best practice&quot; approach?</p>
