Browsers fall through these until they find one they recognize. However, IE's must-ignore behavior is
nonconformant, so we have to use special comments to hide markup from it. This is ugly and large, but it is
technically valid, and it does seem to work in all modern browsers.
Mechanics
Strict validation will find and report all applet elements that you need to fix. Alternatively, you can just do a
quick search for <applet .
You need to change this twice, once for IE and once for other browsers. The IE-specific object element wraps
the other object element. We use IE conditional comments to hide the inner object element from IE.
For the outer element:
Change applet to object in both the start- and end-tags.
If the value of the code attribute ends in .class , remove .class . The value of the code attribute should
be the fully package-qualified name of the applet, nothing more or less.
Add a classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" attribute.
Move the codebase attribute (if any) into a param child element with a name="codebase" attribute. The
value attribute of this param element should have the actual codebase as its value.
Add a new codebase attribute
Move the archive attribute (if any) into a param child element with a name="archive" attribute. The
value attribute of this param element should have the value of the old archive attribute as its value.
Change the object attribute (if any) to a data attribute with the same value.
