问题描述

我想基本上制作一个不需要关闭的自定义标签,然后将css应用于该标签.

I want to basically make a custom tag that doesn't need to be closed and apply css to it.

看起来不应该是这样的:< customtag></customtag> .

It shouldn't look like this:<customtag></customtag>.

它应该看起来像这样:< customtag> < customtag/> .

It should look like this: <customtag> or <customtag/>.

推荐答案

除非已将元素定义为 void元素,它们必须具有结束标记.

Unless an element is already defined to be a void element in the HTML spec, they must have a closing tag.

因此,所有自定义Web组件都必须具有关闭标签.此外,自定义元素的名称中必须带有连字符,以避免与可能的字符产生冲突.将来的标签.

Because of this, all custom web components must have a close tag. Additionally, custom elements must have a hyphen in their names to avoid conflicting with possible future tags.
