I have a square box, that I need to create a dual lined border of differing widths.
I've selected the shape and then done a
10px stroke inside. Now I want to add a 2nd rectangle of
5px width that is
5px inside the outer stroke on all sides.
For clarity, this is one
10px line around the full edge of the background shape. Then a 2nd line of
5px which has a
5px gap between it and the outer stroke.
Any pointers on how to achieve this second stroke accurately will be greatly appreciated.
