非标
此特征是非标准的，且不在标准轨道中。不要在面向 Web 的生产站点中使用它：它不适用于每个用户。实现之间可能存在大的不兼容性，且行为将来可能改变。
过时
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
<noembed>
element is an obsolete, non-standard way to provide alternative, or "fallback", content for browsers that do not support the
<embed>
element or do not support the type of
embedded content
an author wishes to use.
This element was deprecated in HTML 4.01 and above in favor of placing fallback content between the opening and closing tags of an
<object>
元素。
While this element currently still works in many browsers, it is obsolete and should not be used. Use
<object>
instead, with fallback content between the opening and closing tags of the element.
范例
The message inside
<noembed>
tag will appear only when your browser does not support
<embed>
标签。
Show an alternative content
<embed type="vide/webm" src="/media/examples/flower.mp4" width="200" height="200"> <noembed> <h1>Alternative content</h1> </noembed> </embed>
