Blog Archive pages: Borders on top of borders in post grid widgets

Hello awesomes,

I am styling my site with Kleo, and trying to style the blog grid display on archive pages, but I get some strange borders on top of the original borders around the Posts widgets…

I know I might not be explaining my self very well, so I am attaching an image 🙂

I need to remove the “fat” ugly borders and keep the underlying ones (the thin ones)… I am pretty sure we’re talking about 2 layers of borders one on top another, but I’m not much of a dev. so maybe I’m wrong.

I don’t know if those remaining “ugly” borders are to display the color code of the category? the color code is nice, but not mandatory if it’s going to keep those borders….

Anyway, hope you can help me out solve that thing out.

Thanks a lot, cheers!
