The angle of the line can be controlled by adjusting the widths of two adjacent borders (one of them opaque) relative to each other. Pie slices are drawn in clockwise order in a counterclockwise direction. These pie slices are positioned: Inside a square element of (2 * radius)x(2 * radius) pixels; with border-radius: radiuspx for a circular shape
