Sidebar

Ive looked but I cant figure it out. I'm pretty good with the S2 coding and managed to get everything I wanted from component before (on another LJ) but I'm trying to find a way to shrink the sidebar components. Is this possible and if so.. how do I do it?

Its the only thing thats stopping me from wanting a component layout once I get a paid account.. the sidebar is to wide

Thanks ♥
