billing and shipping floated alongside eachother

I have been trying to float billing and shipping alongside eachother but for some reason cant seem to make that happen. You will have to visit the site and put a product in the cart and register to get to the page where you can add a different shipping address to see what I mean. Here is a link to the test site. Thanks in advance to anyone willing to help.

I am still interested in seeing how you can float Billing and Shipping alongside eachother but due to deadlines I had to move on and design a different full width solution with billing appearing above shipping.

Hi,

You just have to set a width and a float:left on the id "hikashop_payment_methods" and "hikashop_shipping_methods" like:
And add the property "clear:both;" on the div after the shipping method div.
