How to remove space above product on product detail page

Hi,

Would anyone be able to suggest some CSS to remove the space above the product information on a product detail page. Or another way of putting it, move the product detail to the top of the page. In my scenario, I do not need to display breadcrumbs or a product category, so this becomes a quite large and empty space on my site. See the attached image below.

Any help greatly appreciated.

Cheers.

No thoughts anyone?
