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-progress
CSS pseudo-element is a Mozilla extension that represents the lower portion of the track (i.e., groove) in which the indicator slides in an <input>
of type="range"
. This portion corresponds to values lower than the value currently selected by the thumb (i.e., virtual knob).
Note: Using ::-moz-range-progress
with anything but an <input type="range">
doesn't match anything and has no effect.
Syntax
::-moz-range-progress
Examples
HTML
<input type="range" min="0" max="100" step="5" value="50"/>
CSS
input[type=range]::-moz-range-progress {
background-color: green;
height: 1em;
}
Result
A progress bar using this style might look something like this:
