HTML Tags
HTML <applet> Tag
The <applet> tag once embedded Java applets in web pages, but it is obsolete and removed from HTML5. Modern pages use <object>, <embed>, or <iframe> instead.
The <applet> Tag
The <applet> element was used to embed a Java applet, a small application that ran inside the browser via a Java plugin. Java applets required a browser plugin that modern browsers no longer support.
Because of security problems and the removal of plugin support, <applet> is obsolete. It was deprecated in HTML 4.01 and removed entirely from HTML5.
⚠️
The <applet> tag is obsolete and must not be used. Java applets no longer run in modern browsers. Embed external content with <iframe>, media with <embed>, or generic resources with <object>.
