Slider
A draggable handle on a track for picking a range value.
A slider lets the user pick a value by dragging a handle along a horizontal track. The further right, the higher the value. Sliders are great for things like volume, brightness, or price ranges where a precise number is less important than a feel.
When the exact number matters, pair the slider with a numeric label that updates as the user drags. For two values at once (a range), use a slider with two handles.
