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


CSS content

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

HTML content

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


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

The thumb of the <input type=right> styled in green


Not part of any specification. This is a proprietary pseudo-element specific to Gecko.
