HTML5 中的自闭合标签(空元素)

2022-01-18 00:00:00 element tags html

HTML5 规范 8.1.2.1 开始标签的第 6 步说 void 元素 可能只有一个 / 字符.我认为这样可以更轻松地将 XHTML 网站迁移到 HTML5.

Step 6 of 8.1.2.1 Start tags of the HTML5 spec says that void elements may have a single / character. I think this is so it's easier to migrate sites that are XHTML over to HTML5.

最佳做法是什么?

例如,如果我正在使用 HTML5 (<!DOCTYPE html>) 制作网站,我应该怎么做?

E.g., if I'm making a website with HTML5 (<!DOCTYPE html>), which should I do?

  1. 没有斜线

  1. without the slash

<meta http-equiv="content-type" content="text/html; charset=utf-8">

  • 用斜线

  • with the slash

    <meta http-equiv="content-type" content="text/html; charset=utf-8" />
    

  • 如果两者都在所有浏览器上正确呈现,那么我假设 (1) 没有斜线是可行的方法,因为它更多的是 HTML5.

    If both render correctly on all browsers, then I'm assuming (1) without the slash is the way to go since it's more HTML5.

    推荐答案

    最佳实践没有共识,根据规范作者 Ian Hickson 的说法,这并不重要.

    There is no consensus on best practice, and according to the author of the spec, Ian Hickson, it does not matter.
