I am trying to implement a scroll bar. A normal scrollbar path will be from the leftmost boundary to the rightmost boundary.
I want a scrollbar that will stop scrolling once 20px is left to reach the leftmost boundary and the same for the right side.
For more explanation:
Suppose the scrollable window size is 100px. Then a normal scrollbar will cover the full 100px but my scrollbar will cover just 100px-(20px + 20px) (subtracting 20px from both sides)
Please guide me on how I could achieve this also let me know if more information is required.
