用于内容语言的HTML元标记(HTML meta tag for content language)

以下两个HTML元标记之间有什么区别,用于指定西班牙语网页内容:

<meta name="language" content="Spanish">

<meta http-equiv="content-language" content="es">

What is the difference between the following two HTML meta tags, for specifying spanish web page content:

<meta name="language" content="Spanish">

and

<meta http-equiv="content-language" content="es">

最满意答案

<meta name="language" content="Spanish">

在任何规范中都没有定义(包括HTML5草案 )

<meta http-equiv="content-language" content="es">

这是一个可怜的人的版本的一个真正的HTTP标题,应该真的在标题中表达。 例如:

Content-language: es
Content-type: text/html;charset=UTF-8

它表示,该文件是面向西班牙语的人士(但这并不意味着该文件用西班牙语写成,例如,它可以用英文写成西班牙语语言课程的一部分)。

从规格 :

Content-Language实体头字段描述了封闭实体的预期受众的自然语言。 请注意,这可能不等于实体中使用的所有语言。

如果您想要说明文件是用西班牙语写的,请使用:

<html lang="es">

<meta name="language" content="Spanish">

This isn't defined in any specification (including the HTML5 draft)

<meta http-equiv="content-language" content="es">

This is a poor man's version of a real HTTP header and should really be expressed in the headers. For example:

Content-language: es
Content-type: text/html;charset=UTF-8

It says that the document is intended for Spanish language speakers (it doesn't, however mean the document is written in Spanish; it could, for example, be written in English as part of a language course for Spanish speakers).

From the spec:

The Content-Language entity-header field describes the natural language(s) of the intended audience for the enclosed entity. Note that this might not be equivalent to all the languages used within the entity-body.

If you want to state that a document is written in Spanish then use:

<html lang="es">
