`::-webkit-progress-value` CSS pseudo-element

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.

Syntax

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