Description overlaps "Add to cart" button

-- url of the page with the problem -- : fireworksland.com/stores/shirts/2013-05-09-03-19-26
-- HikaShop version -- : 2.6.0
-- Joomla version -- : 3.4.6
-- PHP version -- : 5.4.45
-- Browser(s) name and version -- : Safari 9.0.1
-- Error-message(debug-mod must be tuned on) -- : There is no error message

See the attached screen shot for an example. The product description starts above the "Add to Cart" button. What I would like is for the description to be completely below the "Add to cart" section.

Is there some CSS I can add to my custom CSS that will force the description to be entirely below the Add to Cart area?

Thank you

That did it, thank you!
