::-moz-range-track

Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.

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.

Syntax

::-moz-range-track {
  /* ... */
}

Examples

>

HTML

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

CSS

input[type="range"]::-moz-range-track {
  background-color: green;
}

Result

A range slider using this style might look something like this:

A range with the track green
