Trying to have fullscreen page, with no scroll.

Hi GP, congratulations with the 5 years :)

Im trying to make a fullscreen page, but for homepage only. I have this css

.html {
width:100%;
height:100%;
overflow:hidden;
}

It works perfectly, to remove the scroolbars. But it does it on everypage, then i tried editing it like this

.home #html {
width:100%;
height:100%;
overflow:hidden;
}

but i can't seem to get it to work on the frontpage only. Any of you clever guys in here that knows why i dosent work on frontpage only?

Im using newest version of GPP
