A simple trick to make comments from the original post author stand out a bit more in the comment listing - useful for seeing replies to comments.
First you need to create a style to apply to highlighted comments on your blog. To do this, either in the admin editor or via SSH/FTP edit the file style.css.
Add a line that applies a style to a class called authorstyle:
:::css
.authorstyle { background-color: #fffddf !important; }
Here we've set the background to a nice yellow.
Next find the comments.php file in your theme folder and look for the following line:
:::php
<li <?php echo $oddcomment; ?>id="comment-<?php comment_ID() ?>"></li>
And replace it with:
:::php
<li class="<?php if ($comment->user_id == 1) $oddcomment = "authorstyle"; echo $oddcomment; ?>"></li>
What this is doing is checking whether the user_id of the comment poster equals 1 (the admin user - who set up the blog) and if so showing the comment as highlighted. This will only work on a single-user blog (i.e. if you have more than one author their posts will not be highlighted).
