推荐答案
标准已被简化，因为之前的文档类型也是如此神秘。新的文档类型只是<！DOCTYPE html> 。您可能想知道为什么它不是<！DOCTYPE html5> ，但它仅仅是因为它只是HTML标准的更新而不是新版本的任何东西。您可以在下面看到，所有元素现在都可以拥有语言属性。
The standard has been simplified because the previous doctypes were too cryptic. The new doctype is simply <!DOCTYPE html> . You may wonder why it is not <!DOCTYPE html5> but it is simply because it is just an update to the standard of HTML and not a new version of anything. As you can see below, all elements can now have a language attribute.
< html>元素是文档的根元素。每个文档
必须以该元素开头，并且它必须包含< head>和
< body>元素
The
<html>element is the root element of a document. Every document must begin with this element, and it must contain both the<head>and<body>elements.
使用lang属性在这个元素上指定
文档的主要语言被认为是一种很好的做法。 / p>
It is considered good practice to specify the primary language of the document on this element using the lang attribute.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Hello World</title>
</head>
<body>
<h1>Hello World</h1>
<p>
Jamie was here.
</p>
</body>
</html>
