Web/CSS/ -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.

Syntax

::-webkit-progress-inner-element

Examples

These examples work only on Blink and WebKit.

Adding a black border around the progress bar

In this example, a 2px black border is added around the progress bar.

HTML

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

CSS

progress {
  -webkit-appearance: none;
}

::-webkit-progress-inner-element {
  border: 2px solid black;
}
