wp-attention-boxes

I can’t count how many times I’ve had to open 3 new tabs in my chrome browser, to look up CSS reference information, to figure out how to create an attractive, attention-attracting box, to emphasize a sentence or paragraph in my blog. This is remarkably useful.

I can insert all the “div”s I want by clicking the area the plugin displays on the editing pages, but if there’s a way to customize their appearance, I don’t see how to get to it. The boxes appear without borders or background. Perhaps it’s a version incompatibility issue.
