Hi Paula,

For each area/region, can you buffer your line to create a polygon, then erase half of your buffer polygon (the half that is outside the region)?  You could then apply a style to the polygon.  How would that look?

To erase half of the buffer, you could probably split the buffer with your line, then erase.  Or if your lines are the boundary of polygons, use the polygon to "erase outside".

Subject: Line inside style

Hello community,

I am trying to replicate something similar to this image. 

I want to be able to highlight certain areas from the rest, preferably with another thicker and transparent line but it must be inside that area's line.
The best I can do is with one of the line styles which includes marks inside the outline. But this is a nicer look.

Thanks for any help I can get.
