html - self 关闭的 HTML/XML 标签的正确术语是什么？

Question

我不记得用来描述自关闭的 html 标签之间的区别的术语，

例如，<hr />自己关闭。

<p>This doesn't</p>

Answer 1

XML specification 使用的术语是:

Empty-element tag

relevant part规范说:

Tags for Empty Elements

[44]  EmptyElemTag ::= '<' Name (S Attribute)* S? '/>' [WFC: Unique Att Spec]

Empty-element tags may be used for any element which has no content, whether or not it is declared using the keyword EMPTY. For interoperability, the empty-element tag SHOULD be used, and SHOULD only be used, for elements which are declared EMPTY.

但是，您可能还经常听到术语自闭合标签。
