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 ::-webkit-progress-value CSS pseudo-element represents the filled-in portion of the bar of a <progress> element. It is a child of the ::-webkit-progress-bar pseudo-element.

Note: In order to let ::-webkit-progress-value take effect, appearance needs to be set to none on the <progress> element.


::-webkit-progress-value {
  /* ... */


This example will only work in browsers based on Blink or WebKit.


<progress value="10" max="50"></progress>


progress {
  -webkit-appearance: none;

::-webkit-progress-value {
  background-color: orange;


Result screenshot

A progress bar using the style above would look like this:

A long orange and grey box. The left 20% is orange. The right 80% is grey.


Not part of any standard.
