Why seek to differentiate your own comments on your blog?
Because it will allow your visitors to identify and easier to follow the conversation. Some themes for WordPress offer this feature by default, but here’s a quick guide to differentiate the author’s comments.
Locate the style attributed to comments
Look in your stylesheet (usually style.css file) style applied to comments. It should look like this:
comment { background:#3F3F3F; margin:0 0 6px; padding:12px 12px 6px; }
Create a second style for the author’s comments
Now you’ll create a second class that applies to the author’s comments. The simplest is to use the same style with changing the background color. Your style will look like this:
comment-author { background:#3E3E3E; margin:0 0 6px; padding:12px 12px 6px; }
Locate the loop to display the comments
Then open the comments.php file and find the loop that allows the display of all comments:
Inside is the function that calls the class that stylized comments.
Insert a condition
Just  add a condition for the class how author-created earlier is called if the author of the commentary is also the author of the ticket:
<?php if($comment->user_id == $post->post_author) { $class = 'comment-author'; } else { $class = 'comment'; } ?> <div> <?php comment_text() ?> </div>
