The purpose of a plug-in, is to extend the functionality of the

HTML Helpers (Plug-ins)
Helper applications are computer programs that extend the standard
functionality of a web browser.
Helper applications are also called plug-ins.
Examples of well-known plug-ins are Java applets.
Plug-ins can be added to web pages with the <object> tag or the <embed> tag.
Plug-ins can be used for many purposes: display
maps, scan for viruses, verify your bank id, etc.

To display video and audio: Use the <video> and <audio> tags. |

The <object> Element
The <object> element is supported by all browsers.
The <object> element defines an embedded object within an HTML document.
It is used to embed plug-ins (like Java applets, PDF readers,
Flash Players) in web pages.
Example
<object width="400" height="50" data="bookmark.swf"></object>
The <object> element can also be used to include HTML in HTML:
Example
<object width="100%" height="500px" data="snippet.html"></object>
Or images if you like:
Example
<object data="audi.jpeg"></object>
The <embed> Element
The <embed> element is supported in all major browsers.
The <embed> element also defines an embedded object within an HTML document.
Web browsers have supported the <embed> element for a
long time. However, it has not been a part of the HTML
specification before HTML5. The element will validate in an HTML5
page, but not in an HTML 4 page.
Example
<embed width="400" height="50" src="bookmark.swf">
|
Note that the <embed> element does not have a closing tag. It can not contain alternative text. |
