::-webkit-progress-inner-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-inner-element CSS pseudo-element represents the outermost container of the <progress> element. It is the parent of the ::-webkit-progress-bar pseudo-element.

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