How to Set Borders in Product Listing

Hello,
I am trying to set the borders size and color in Display/css/Front-end Css file, but nothing change in my layout.
Anyone have an idea how can i make it?
Thanks

You can add CSS like this:

div.hikashop_products div.hikashop_subcontainer {
border: 1px solid;
}

thanks for your reply.

I`ve tried that before, indeed the borders in the product image are visibile, but as well as the rest of the tables "add to cart", "quant", "registration camps" and so on...

its got to be some other way...

Then like the new CSS I modified in my previous post

Yes,
