你能在HTML5中定义自己的自闭标签吗？ [英] Can you define your own self-closing tag in HTML5?
问题描述
我已阅读此主题，但我还是有疑问。
有没有办法定义void标签？
I have read this topic, but I still have doubts. Is there any way to define void tag?
我试过这个：
<icon class="home"/> (know that slash isn't obligatory)
但是，如果此标签后有任何文字内容FF关闭它们。
But, if there is any text content after this tag FF closes them.
<icon class="home"/> Go home
制作
<icon class="home">Go home</icon>
我应该定义哪个标签是void-element？或者HTML5是不可能的？
Should I define somewhere that tag is void-element? Or is it impossible to do with HTML5?
推荐答案
目前这不是一个答案，因为它没有完全解决这个问题，但是它不适合评论部分。
This is currently not an answer because it does not fully address the question, but it did not fit into the comment section.
/> <>中的 / 如果解析为html5规范，浏览器会忽略/ code>（外部元素 MathLM 除外） SVG ，因为对于 modules 的元素，他们的规范具有自封闭元素，因此它需要保持有效）
The / in /> is ignored by the browsers if parsed to the html5 specs (except foreign elements of MathLM and SVG, because for the elements of this modules their specs has self enclosing element, so there it needs to stay valid)
规格的相关部分：
- W3C - HMTL5 - Elements
- W3C - HMTL5 - Start tags
（浏览器应如何处理缺失标签以及忽略 / 的相关部分是缺少，我需要查看这个）
(The relevant part how browsers should handle missing tags and that they ignore / is missing, i need to look this up)
如果元素是 void元素没有生成结束标记，因为它不需要一个。
If the element is a void element no closing tag is generated, because it does not require one.
对于其他元素，如果缺少结束标记，则创建结束标记。
所以如果你写这样的东西：
For the other elements the closing tag is created if it is missing. So if you write something like this:
<div>
<div/>test
</div>
这将导致
<div>
<div>test</div>
</div>
因为 / 被忽略。
默认情况下，自定义元素为 non-void 。我知道有一个自定义元素的草稿但老实说，我不知道某些浏览器是否已经支持它。但即使是这样，你也会遇到向后兼容的问题。所以我不建议使用它。
Custom elements are non-void by default. I know there is a draft for Custom Elements but honestly i don't know if it is already supported in some browsers. But even if it is, you will have the problem of backward compatibility. So i would not recommend to use it.
即使这样定义一个没有前缀 x - 的标签名称，一个坏主意，因为如果后来某个元素被规范添加了您选择的名称，如果它有另一个含义，那么您将遇到问题。
Even so defining a tag name not prefixed with an x- is a bad idea because if later an element is added by the specs with the name you choose and if that has another meaning you will have a problem.
我有一个查看规格的时间我将提供相应的缺失部分来证明这一点。
As soon as i have time to look up the specs i'll provide the corresponding missing parts to proof this.
