为什么可以在头部内添加文本 [英] Why is it possible to add text inside the head section

问题描述

为什么HTML页面的head部分中的文本在DOM中呈现?

Why does the text inside a head section of a HTML page get rendered in the DOM?

根据 MDN ，标头部分应执行以下操作:

According to MDN the head section should do the following:

HTML元素提供有关文档的常规信息(元数据)，包括其标题以及指向其脚本和样式表的链接.

The HTML element provides general information (metadata) about the document, including its title and links to its scripts and style sheets.

如果在页面的头部放置一些文本，它将被放置在呈现的网页的正文部分.这不是奇怪的行为吗?

If you place some text inside the head section of the page, it will get placed in the body section of the rendered webpage. Isn't this weird behaviour?

推荐答案

head标记中的文本无效.

浏览器的错误更正会将文本从head移到body

The error correction of the browser moves the text from the head to the body
