`::-moz-range-thumb` CSS pseudo-element

The ::-moz-range-thumb CSS pseudo-element is a Mozilla extension that represents the thumb (i.e., virtual knob) of an <input> of type="range". The user can move the thumb along the input’s track to alter its numerical value.

[!NOTE] Using ::-moz-range-thumb with anything but an <input type="range"> doesn’t match anything and has no effect.

Syntax

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

Examples

HTML

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