CSS Single Product page Woocomerce, put image and description block side by side


I have a ugly layout for my single product page in woocomerce and i want put side by side, product image and description with a little modification of CSS. I Achieve reduce both to 50% now, but seems that margins dont let me put both blocks side by side.

Somebody know how do it?

I attach a screenshot with graphic explanation of final result.

both blocks (image and description) are now full width and one above other, and i want side by side, seems simple for someone who know more CSS than I :smiley:

Thanks for advance
