How to have custom post or page template which is not wordpress look and feel

Hi There,

I am fairly new to wordpress. I want my customer to create custom post or page. I downloaded the plugin custom post type UI. The good thing is that it allows me to create custom fields. However, the look and feel is of wordpress.

I want the custom look and feel or look and feel of Zerif for customers when they want to add the post/page. Is there any way to do this.

Regards,
