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-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 content
progress { -webkit-appearance: none; } ::-webkit-progress-bar { background-color: orange; }
