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-even-less-good-value gives a red color to a <meter> element when the value and the optimum attributes fall outside the low-high range, but in opposite zones. To illustrate, it applies when value < low < high < optimum or value > high > low > optimum.
Specifications
Not part of any specification. This is a proprietary pseudo-element specific to WebKit/Blink.
