UI is getting overridden

[sibanand-cis]

I am getting this :

when I am using active_skin with active admin 0.6.0 for rails 3.2.13.
The css contains body.active_admin prefix to the styles and it is causing the issues, here is a snippet:
body.active_admin #header ul.tabs { display: inline-block; height: 100%; margin: 0; padding: 0; } body.active_admin #header .header-item { float: left; height: 20px; position: relative; top: 2px; }

Please guide me what I am missing here.

@sibanand-cis you need to switch the order of your mixins. @import "active_skin"; is likely ontop
