meter状态标签，可以定义电压
optimum是标准状态
low与high之间呈现绿色，其余呈现黄色
<meter value=”220” min=”20” max=”380” low=”200” high=”240” optimum=”220”></meter>
自动计算百分比
<meter value="0.75">75%</meter>
有步长的进度条
<progress value="30" max="100"></progress>
不断加载的进度条
<progress max="100"></progress>
datalist为input定义下拉列表

<p>html5是构建web内容的一种语言描述方式。html5是互联网的下一代标准，是构建以及呈现互联网内容的一种语言方式．被认为是互联网的核心技术之一。html产生于1990年，1997年html4成为互联网标准，并广泛应用于互联网应用的开发。
html5是web中核心语言html的规范，用户使用任何手段进行网页浏览时看到的内容原本都是html格式的，在浏览器中通过一些技术处理将其转换成为了可识别的信息。html5在从前html4.01的基础上进行了一定的改进，虽然技术人员在开发过程中可能不会将这些新技术投入应用，但是对于该种技术的新特性，网站开发技术人员是必须要有所了解的。 [1-2] </p>
