Add a Cool Style to Blogger Threaded/Nested Comments

If you need a fresh style to the threaded comments of a standard Blogger template, here's a simple CSS that will help you to apply a different background, make your avatars rounded, add a border with rounded corners and a triangle which is actually an HTML entity to get that speech bubble look on your comments.

You can see a demo here.

To have this style in your comments, all you need to do is to paste the below code inside the CSS part of the template, which is between the <b:skin> and </b:skin> tags.
