Currently, there's a moveBar function which calculates height, top and right;
- because of
height calculations, I can't have a fixed-height .ss-scroll element (usable for really long scrolling areas),
- because of
right calculations, i can't move .ss-scroll further from the edge (right: 5px;), a design issue
I see there's a .ss-content.rtl class which uses calc() to adjust width, but there's no .ss-scroll.rtl which would adjust right for this element in rtl direction, where at least the calculation for right could be fully dropped for css.
