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.


::-webkit-meter-suboptimum-value {
  /* ... */


This example will only work in browsers based on WebKit or Blink.


<meter min="0" max="10" low="3" high="7" value="2">Score out of 10</meter>


meter::-webkit-meter-suboptimum-value {
  background: pink;
  height: 100%;
  box-sizing: border-box;



Not part of any standard.
