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.
