问题描述
根据和 HTML5课程，< embed> 标记对于HTML5是新。但是我一直在使用它......永远，它可以在我测试过的任何浏览器中使用它。 页面例如使用< embed> 标签，它适用于所有浏览器。
为什么？这只是一个由渴望的浏览器制造商提前实施的草案吗？
的确同意W3Schools（），但你是对的。 < embed> 已被使用了很长时间，但对于HTML5来说已经被正确地标准化了。 a href =http://www.w3.org/TR/1999/REC-html401-19991224/struct/objects.html#h-13.5 =nofollow> < object> 。与在HTML 4中弃用的州< embed> 的几个来源相反，我在 （或），这意味着它是可能从未正式标准化。 似乎更少进化（正如人们所期望的）。有大量关于< applet> 的文档，但我找不到关于< embed> 任何地方官方。
According to W3Schools and Pluralsight's HTML5 course, the <embed> tag is "new" to HTML5. But I've been using it since...forever, and it works in any browser i've tested it against. This page for example, uses the <embed> tag and it works in all browsers.
Why? Was it just a draft that got implemented ahead of time by eager browser makers?
The Mozilla docs do agree with W3Schools (for once), but you are right. <embed> has been in use for ages but was standardized properly for HTML5.
HTML 4 officially used <object>. Contrary to several sources which state <embed> was deprecated in HTML 4, I can't find any mention of it in the HTML 3 DTD (or in 3.2), which means it was probably never standardized officially. HTML 2 seems to be even less evolved (as one might expect). There is plenty of documentation about <applet>, but I can't find a single mention about <embed> anywhere official.
