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, -webkit-appearance needs to be set to none on the <progress> element.

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