Applets: OBJECT (relative height)

This test case tests the <object> tag with its height attribute which, similar to the <img> tag, explicitly specifies the height of the java applet. The height attribute can either be an absolute height using an integer value of pixels or a relative height using a relative percentage value.

If the height attribute of an <object> is using a relative height and if the height of its containing block is not specified explicitly (i.e., it depends on content height), then the height of the <object> will compute to "auto". When this case happens, then the height refers to the intrinsic height for <object> which is 0px. Therefore, if the height attribute of an <object> is using a relative height, then the height of its containing block should be specified explicitly.

Test Case #1: sample java applet dimension scaling using relative heights
(using <object codebase=class pathname data="class name" height=percent value> </object>)

Java Applet Dimensions Scaled Down (Reverse Scaling)

Original object (with an height of 80px)

Object height="75%" within a <p> with a specified height of 400px

Object height="50%" within a <p> with a specified height of 400px

Object height="25%" within a <p> with a specified height of 400px

Object height="50%" within a <p> that has no specified height, with an auto-height <p>

The last <object>, just above, should NOT BE DISPLAYED.
