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-progress-bar CSS pseudo-element is a Mozilla extension that represents the progress bar inside a <progress> element. (The bar represents the amount of progress that has been made.)

Syntax

::-moz-progress-bar

Examples

HTML

<progress value="30" max="100">30%</progress>
<progress max="100">Indeterminate</progress>

CSS

::-moz-progress-bar {
  background-color: red;
}

/* Force indeterminate bars to have zero width */
:indeterminate::-moz-progress-bar {
  width: 0;
}

Result

The first bar from above should look like this:
