[SOLVED] How to change the top position of the widgets in only one page

Hi,
I need to put a big slide show in the home page , just after the tittle and before the main content and I would like to change the top position of the widget from that page in order to give space on the right side for that
I tried to do:

body.home div.widget{
top:800px !important;
}

but it doesn't work, the widgets doesn't move position at all .
