CSS - ::-moz-range-progress

The ::-moz-range-progress CSS pseudo-element represents the portion of the "track" (the groove in which the indicator aka thumb slides) of an <input> of type="range", which corresponds to values lower than the value currently selected by the thumb.

Example

input[type=range]::-moz-range-progress {
  background-color: green;
  height: 1em;
}

HTML content

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

Output

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

Syntax  

::-moz-range-progress { style properties }

Description  

The ::-moz-range-progress CSS pseudo-element represents the portion of the "track" (the groove in which the indicator aka thumb slides) of an <input> of type="range", which corresponds to values lower than the value currently selected by the thumb.

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