Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The ::-moz-range-track CSS pseudo-element is a Mozilla extension that represents the track (i.e., groove) in which the indicator slides in an <input> of type="range".

Note: Using ::-moz-range-track with anything but an <input type="range"> doesn't match anything and has no effect.

Example

HTML

<input type="range" min="0" max="100" step="5" value="50"/>
