In downlevel-revealed conditional comments, the HTML content inside the conditional statements is revealed to browsers that don’t support conditional comments, because the conditional statements—and only the conditional statements—are ignored. If the statement evaluates to true (in a supporting browser), the content inside the conditional statements is also revealed.

<!--[if !IE]>-->
  <p>This is shown in downlevel browsers.</p>
