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

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] For ::-webkit-progress-value to take effect, appearance needs to be set to none on the <progress> element.

Syntax

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

Examples

CSS

progress {
  -webkit-appearance: none;
}

::-webkit-progress-bar {
  background-color: orange;
}

HTML

<progress value="10" max="50"></progress>
