<Embed> A tag is a new tag in HTML 5.

Attribute value description
Height pixels sets the height of the embedded content.
The url of the src URL embedded in the content.
Type defines the type of embedded content.
Width pixels: Set the width of the embedded content.

It is a new tag in HTML 5. In fact, it is no stranger in HTML 4.

Why is it a chicken rib?

This is because the value of the src attribute must specify the actual file extension. For example, if you want to use it to play mp3 files,

The file extension in the url must be mp3. If you want to use a dynamic web page

For example, "getMp3.php? Id = 12321 ", it cannot be played at all,

Even if you specify the type attribute "audio/mpeg3", it cannot recognize it as an mp3 file.
