HTML Plug-ins


Plug-ins are computer programs that extend the standard functionality of the browser.


Plug-ins

Plug-ins were designed to be used for many different purposes:

  • To run Java applets
  • To run Microsoft ActiveX controls
  • To display Flash movies
  • To display maps
  • To scan for viruses
  • To verify a bank id

Warning !

Most browsers no longer support Java Applets and Plug-ins.

ActiveX controls are no longer supported in any browsers.

The support for Shockwave Flash has also been turned off in modern browsers.


The <object> Element

The <object> element is supported by all browsers.

The <object> element defines an embedded object within an HTML document.

It was designed to embed plug-ins (like Java applets, PDF readers, and Flash Players) in web pages, but can also be used to include HTML in HTML:

Example

<object width="100%" height="500px" data="snippet.html"></object>
Try it Yourself »

Or images if you like:

Example

<object data="audi.jpeg"></object>
Try it Yourself »


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 src="audi.jpeg">

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

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

Example

<embed width="100%" height="500px" src="snippet.html">
