ion-range
The Range slider lets users select from a range of values by moving the slider knob. It can accept dual knobs, but by default one knob controls the value of the range.
Range Labels
Labels can be placed on either side of the range by adding the
slot="start" or slot="end" to the element. The element doesn't have to
be an ion-label, it can be added to any element to place it to the
left or right of the range.
Usage
