How to comment-out a large section?

[Benjames]

How can I comment out a whole section of code?
Do I have to do this:
<!-- -->
to each line?
Thanks.

  <!--Begin Video Browser Container-->
  <!-- we need a fixed height here if done this way to stablize the ajax load -->
  <div class="container-wide">
    <div class="browse-videos" style="height: 332px;">
      <div id="videos-ajax">
        <div id="videoajax">
          <ul>
	      <li>
	        <a href="videos/[blkfeatured_videos.indexer;block=div]/[blkfeatured_videos.title_seo;block=div]"><div class="browse-videos-title"><!--[blkfeatured_videos.title;block=div;ope=max:14;comm]--></div></a>
	        <div class="browse-videos-member">By:&nbsp;&nbsp;<a href="members/[blkfeatured_videos.uploaded_by]"><b><!--[blkfeatured_videos.uploaded_by;block=div;ope=max:14;comm]--></b></a></div>
	        <a href="videos/[blkfeatured_videos.indexer;block=div]/[blkfeatured_videos.title_seo;block=div]"><img src="uploads/thumbs/[blkfeatured_videos.video_id;block=div].jpg" title="<!--[blkfeatured_videos.title;block=div;comm]-->" alt="video pic" /></a>
	        <div class="browse-videos-duration"><b><!--[blkfeatured_videos.video_length;block=div;ope=max:45;comm]--></b></div>
	        <div class="browse-videos-rating">

	        <div class="browse-videos-date">[var.lang_added]:&nbsp;<!--[blkfeatured_videos.date_uploaded;block=div;comm]--></div>
	      </li>
          </ul>
        </div>
      </div>
      <div class="clear-fix"></div>
    </div>
  </div>
  <!--End Video Browser Container-->
  <div class="container-wide-footer"></div>

No. To comment out blocks of PHP code you can use
/*
...
...
...
*/

To comment out blocks of HTML code
<!--
...
...
...
-->

As long as the comment "tags" (they're called something else) are well formed.
