Layers
 
The DHTML applications Animation, Popup Layers and Menu Maker all use layers. While the Menu Maker application creates the layer for you, the Popup Layers and Animation applications require that you create your own layers prior to using them. Both Netscape and Microsoft's layers are supported.

The creation of layers may be too advanced for some users. Therefore, the Java Script It! web site contains a utility within the Code Online section that will allow you to create fully customizable cross-browser layers (free of charge).
