            No comments
The purpose of a plug-in is to extend the functionality of a web browser.

HTML Helpers (Plug-ins)

Helper applications (plug-ins) are computer programs that extend the standard functionality of a web browser.
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.

----------------------------------------------
<object width="400" height="50" data="bookmar.swf"></object>
-----------------------------------

The <object> element can also be used to include HTML in HTML:

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.

Example

----------------------------------
<embed width="400" height="50" src="bookmar.swf">
----------------------------------


NOte that the <embed> element does not have a closing tag.It closing tag.It can not contain alternative text.

The <embed> element can also be used to include HTML in HTML:

Example
