Styling the home page only

Hello,
Is it possible to style the .content_sparky.span12 in home page to have different background-color than other pages which I want them to have the default background-color of the content?
Thank you in advance.

Yes , on home page body tag has class sparky_home and on all other pages it has class sparky_inner , so you can use:

.sparky_home .content_sparky.span12{
...
}

to target only home page.
