Item problem

Hi, i have a problem with my items on website. I will add to pictures hot it is now and how do i want my items on website to look.

This is how the product look right now ( shrani.si/f/3V/iz/1t0KWd7p/old.png ), but i would like to change the product description to be on the left site next to the image like this ( shrani.si/f/2g/s9/4NjbquJD/new.png ). This can probably some work in css but i cant find it, so pleas if any one knows how to fix this pleas let me know, thank you.
