HTML <applet> tag

Updated: 11/13/2018 by Computer Hope

When writing in HTML (hypertext markup language), the <applet> tag is a block element used to embed a Java applet. It is useful when you want to add more functionality to your web pages. The following sections contain information about this tag, including an example of its code, and related attributes and browser compatibility.

Note

The <applet> tag is deprecated. Instead, use the <embed> or <object> tags.

Example code

<applet code="BounceLetters.class" width="350" height="350">
Java applet that draws bouncing text characters.
</applet>
