Styling help

Hi again, I've grabbed some code to create a little plugin to display recently viewed products, placing the short code in a block hook that inserts on the woo single product page at woocommerce_share. I'm lost as to how to style the list. I added a class to the block (wrvp) but I can't work out how to get anything to apply.

I managed to get the list style to none, but creating the boxes and floating it left and inline is lost on me.

I would like to style it the same as the default woocommerce blocks on the category archive pages. Is there an easy way to use those styles on this block?

To see the Related Products list you'll need to click around on some products.

Thank you.
Andrew
