Showing Light Gray border in Category Blog

Hi,
I am using Ice template.
I´d like to make the articles in my website
showing with the light gray color like in the demo image uploaded .
That page was generated using the "Category Blog" Menu Item Type.
How can I accomplish that look and feel?

Thank You.

Hello,
these are not articles these are modules with icons at top-a.
Please read the template description how to setup the icons
demo.joomlaplates.com/jp_ice/docs/#top-a

Thank you.
I gonna read all the docs and install locally the demo to get better understanding of the template.
If any other doubt arrises I return to the forum.
