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-meter-bar pseudo-class sets the styling for the background of the element. Container of the <meter> gauge that holds the value.


Not part of any specification. This is a proprietary pseudo-element specific to WebKit/Blink.


<meter min="0" max="10" value="6">Score out of 10</meter>
meter {
   /* Reset the default appearance */
  -webkit-appearance: none;
  -moz-appearance: none;
  appearance: none;

meter::-webkit-meter-bar  {
  background: #eee;
  box-shadow: 0 2px 3px rgba (0, 0, 0, 0.2) inset;
  border-radius: 3px;

Note: This will only work in Webkit/Blink-based browsers.
