::-webkit-meter-suboptimum-value

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-meter-suboptimum-value pseudo-element gives a yellow color to the <meter> element when the value attribute falls outside of the low-high range.

Specifications

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

Example

HTML

<meter min="0" max="10" value="6">Score out of 10</meter>

CSS

meter::-webkit-meter-suboptimum-value {
  background: -webkit-gradient linear, left top, left bottom;
  height: 100%;
  box-sizing: border-box;
}

Result

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