<applet>
HTML <applet> Tag
The <applet> tag was used to define an embedded Java applet. The use of Java applets is now deprecated as most browsers no longer support the use of plug-ins, including the Java plug-in.
The <applet> element can contain other HTML tags and text between its opening and closing tags.
Some browsers still support the <applet> tag, but they require additional plug-in or installations to work.
This element is a deprecated HTML tag in HTML 4.01 and is entirely obsolete in HTML5. Use the <object> or <embed> element instead.
Syntax
Syntax （语法）
The <applet> tag comes in pairs. The content is written between the opening (<applet>) and closing (</applet>) tags.
Example of the HTML <applet> tag:
<!DOCTYPE html>
<html>
<head>
<title>Title of the document</title>
</head>
<body>
<applet code="game.class" align="left" archive="game.zip" height="250" width="350">
<param name="difficulty" value="easy">
<b>You need Java to play this game.</b>
</applet>
</body>
</html>
