This page places DIVs over an applet to show how poorly things are rendered when semi-transparent HTML objects are placed over Java.
#A, #B { position: absolute; top: 50px; width: 120px; height: 120px; } #A { left: 10px; background: green; } #B { left: 100px; background: red; opacity: 0.5; }
This also happens if the DIVs are given a high z-index, the applet given a low z-index (applet positioned normally or absolutely).
Unlike my previous report (https://bugzilla.mozilla.org/show_bug.cgi?id=478347) overflow: values seem to have no effect and the rendering of the solid DIV is as expected.
The applet is from the Sun website: http://java.sun.com/docs/books/tutorial/uiswing/components/applet.html
