I looked over several options/tutorials for this, and ended up with the following, which retains the odd/even styling as well as adding a style for author comment:
<div class="
<?php
if ($comment->comment_author_email == "[email protected]")
echo "authorcomment";
else
if ($oddcomment)
echo "odd-comment";
else
echo "even-comment";
?>" id="comment-<?php comment_ID() ?>">
I then tooled around with .authorcomment { } in CSS to make it appear the way I wanted. (sample)
I know next to nothing about PHP, so if anyone can point out how to add the equivalent of “and $comment->comment_author == ‘name'”, I’d appreciate it. The programmer in me also suggests there should be some “endif” statements in there, but when I tried to add them, I broke the page.
