"from settings on text track elements" sounds like it might be attributes on
<track> elements or something. Maybe "Applies CSS override style from user
settings." or similar?

Also put this directly following applyCSSProperties in both header and
implementation, they fit together.

Done
applyCSSProperties belongs to VTTCueBox and applyUserOverrideCSSProperties
belongs to VTTCue.
