::-webkit-progress-bar

In This Article

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.

Summary

The ::-webkit-progress-bar CSS pseudo-element represents the entire bar of a <progress> element. Normally it's only visible as the unfilled portion of the bar, since by default it's rendered below the ::-webkit-progress-value pseudo-element. It is a child of the ::-webkit-progress-inner-element pseudo-element and the parent of the ::-webkit-progress-value pseudo-element.

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

Specifications

Not part of any specification. This is a proprietary pseudo-element specific to WebKit/Blink.

Example

CSS content

progress {
  -webkit-appearance: none;
