Payment method and description on separate lines

[broc93]

Hello. Here's the cart page of my website http://www.prodotti-herblife-vendita-online.it/carrello
I'd like to have the description of the payment methods on a new line instead of having them beginning right after the name of the payment method. How can I do that? Thank you in advance.

  display: block;
  font-size: 10.5px;
  line-height: 25px;
  padding: 0 2px;
}
