How to Highlight Author Comments in WordPress using CSS

Many blogs highlight the author’s comment in the comments section. I’m talking about how to highlight comments posted by the author of the article. You can use many plugins to get this effect (For eg., the Highlight Author Comments Plugin) – but you don’t have to. You can get the get the same effect by adding a small bit of CSS code to your theme.

Most snippets will target and try to find author’s email or user id, but that actually slows your site down. Why not using CSS selector and find author’s comment and change the background color so it is easily pointed out. Pretty smart. After that, it was a simple matter of times to see the result.
My default comments loop in comments.php
<?php wp_list_comments('type=comment&avatar_size=48'); ?>
View the HTML code:

<li class="comment byuser comment-author-Narga bypostauthor even thread-even depth-1" id="comment-1013">
	<div id="div-comment-1013" class="comment-body">
		<div class="comment-author vcard"><img alt='' src='http://www.gravatar.com/avatar/18d31a42990f0421bf83bf9c72bcd1b5?s=48&amp;d=http%3A%2F%2Fwww.gravatar.com%2Favatar%2Fad516503a11cd5ca435acc9bb6523536%3Fs%3D48&amp;r=G' class='avatar avatar-48 photo' height='48' width='48' />		<cite class="fn"><a href='https://www.narga.net' rel='external nofollow' class='url'>Narga</a></cite> <span class="says">says:</span></div>

		<div class="comment-meta commentmetadata"><a href="https://www.narga.net/subscribe-then-get-1-month-free-rapidshare-premium-account/comment-page-1/#comment-1013">October 16, 2009 at 20:35</a>&nbsp;&nbsp;<a class="comment-edit-link" href="https://www.narga.net/wordpress/wp-admin/comment.php?action=editcomment&amp;c=1013" title="Edit comment">(Edit)</a></div>

	</div>
</li>

Open the “style.css” and near the bottom added these lines:

.authcomment {  
       background-color: #B3FFCC !important;  
}

And, that’s it! We hope that you find it useful!
