Adding CSS styles to CoursePress listing and redirecting users from the admin

Hello! I would like to add CSS so my CoursePress listings look similar to what you have on https://premium.wpmudev.org/academy/ can you add those for me?

I would also like to redirect all non-admin users from the dashboard. I’ve added a snippet of code to do this, but it blocks logins from my site’s front page too.

Here’s the snippet:

add_action( 'admin_init', 'redirect_none_admin' );

function redirect_none_admin(){
if(is_admin() && !current_user_can('manage_options')){
wp_redirect(home_url());
}
}

Also, the course page is not displaying breadcrumbs – can you add them so users can go back easily?
