It has been awhile. This time, I'm going to show you a quick and easy way to make your comments (author comments) look different. In a thread full of comments, one might feel the need to isolate the author's comments from readers' comments, probably by highlighting it or making it look different.
This tweak works with both Layout (Minima, Harbor, Denim, Rounders, etc) and Designer (Simple, Picture Window, Awesome Inc, etc) templates. Basically, it'll work with all Blogger 'built-in' templates, probably third party templates as well. Consider this my Christmas gift.
