元素语言

Created: November-22, 2018

lang 属性用于指定元素内容和属性文本值的语言：

<p lang="en">The content of this element is in English.</p>

<p lang="en" title="The value of this attribute is also in English.">The content of this element is in English.</p>

语言声明被继承：

<div lang="en">
  <p>This element contains English content.</p>
  <p title="This attribute, too.">Same with this element.</p>
</div>
