Hi, am trying to use the following suggested mods but can’t figure out the classes that work with them in X theme. Please advise 
Advised mods:

Ideally, I’d like:
(A) Next/Previous button: to inherit the ethos stack post “entry-thumb featured skinny” class style with previous and next post title instead of simply ‘previous’ and ‘next’
(B) Mark as completed button: in similar style to “entry-thumb featured skinny”, or change of color and padding
© Module row on course outline and widget: to change padding as well as colour
Thanks!
