Tips and Comments:
Comment: The range of the measure must be defined, either in text or in the min/max attributes.
Example:
<meter min="0" max="20">5</meter> <meter>2 out of 10</meter> <meter>30%</meter>
<meter min="0" max="20">5</meter> <meter>2 out of 10</meter> <meter>30%</meter>
high number 定义度量的值位于哪个点，被界定为高的值。 low number 定义度量的值位于哪个点，被界定为低的值。 max number 定义最大值。默认值是 1。 min number 定义最小值。默认值是 0。 optimum number 定义什么样的度量值是最佳的值。如果该值高于 "high" 属性，则意味着值越高越好。如果该值低于 "low" 属性的值，则意味着值越低越好。 value number 定义度量的值。
You can use CSS pseudo-elements to process the default display mode (because the display methods of each browser may be different):
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Coolwp.net Demo</title>
<style>
.deal meter { -webkit-appearance: none; }
.deal ::-webkit-meter-bar {
height: 1em;
background: white;
border: 1px solid black;
}
.deal ::-webkit-meter-optimum-value { background: green; } /* 好 */
.deal ::-webkit-meter-suboptimum-value { background: orange; } /* 凑合 */
.deal ::-webkit-meter-even-less-good-value { background: blue; } /* 糟糕 */
.deal ::-moz-meter-bar {
background: rgba(0,96,0,.6);
}</style>
</head>
<body>
<p>
默认的：<meter low="69" high="80" max="100" optimum="100" value="92">A</meter>
<meter low="69" high="80" max="100" optimum="100" value="72">C</meter>
<meter low="69" high="80" max="100" optimum="100" value="52">E</meter>
</p>
<p class="deal">
处理后的：<meter low="69" high="80" max="100" optimum="100" value="92">A</meter>
<meter low="69" high="80" max="100" optimum="100" value="72">C</meter>
<meter low="69" high="80" max="100" optimum="100" value="52">E</meter>
</p>
</body>
