Price box on product page

[homeydclown]

Its a gray box and it holds the biggest price on the product page, and I want to shrink the box from side to side.  I found some it of the CSS on line 1446 and messed with that for a wile but was only able to shrink it up and down or move the box up and down. If anybody knows how to shrink it, please help.  I would appreciate it, thank you!
