Help theming course press with child theme

I am trying to integrate coursepress into a site I'm building for my wife - The site is based around a custom child theme of the "stricking multiflex" theme (

I like the majority of your included course pro themes styling. Is there an easy way to integrate the styling from the course components of your theme into my theme without it breaking everything. I've copied across the css into my child theme but it doesn't work properly.

I'm not a professional so please forgive me if this is beyond the scope of your support, any help would be appreciated.

Kind regards,
