There’s a Site Options –> Custom Stylings & CSS box that’s a part of Sterling’s theme.
I did some edits directly to the CSS itself when designing the site a year ago (typically not the smartest thing, I know), but I started just copying and pasting portions of what I edited to the Custom CSS box and some of the styles have come back.
So basically, even if something was marked as !important it was getting re-written, for some reason (no recent updates to WordPress or the theme).
Does that answer your question?
