Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.

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.
