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

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-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" />

CSS

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

Result

A progress bar using this style might look something like this:

The thumb of the 'input type=right' styled in green
