Zencache breaks CSS

Hello, it does sound positive that i decided to use zencache cause the others to big etc…but i do have a problem. The style is getting messed up.
So im not sure when it happens, after some hours or days, but the front stays ok. But other pages you can see the styling is gone.

Example, if you create a html page with text and images you give that some styling, if you take that out…all goes automatically to the left….
Thats what i see ….

How do i solve that?
Or better, why is this happening?
