role slider

Slider draft v0.1.0

Lets people pick a value in a range by moving a thumb along a track.

A slider sets a value whose position in a range matters more than its exact figure: a volume, a brightness, a price ceiling. A thumb slides along a track between a minimum and a maximum, by steps; the value can be shown next to the label. When the exact number matters, a Number field is better, alone or next to the slider.
