TimelineSpan- Global

The TimelineSpan API provides methods to define a set of properties that describe the characteristics and interactive behavior of an element rendered within a time line item.

Since it is extremely important for all of a time line item's collection of spans to be unique, the creation of a new instance should be performed using the createTimelineItem() method of an existing time line Item instance.
