Improved display of bio timeline #21
Description
One solution would be add a background color to some regions, and add a legend. That should be useful to depict periods of time like childhood, university, etc.
Another solution could be to mimic the Wikisource solution, where reference marks appear along the left of the timeline (corresponding to pages, on Wikisource; for the timeline, would be probably years) and when hovered, highlight the corresponding area in the timeline.
For other periods, which may intersect/encompass years, the start/end events could e.g. be shown as as triangles pointing forward/backward, and when one of them is hovered, the other (or both) would be highlighted.
