Layers were the core of a method of dynamic HTML programming specific to Netscape 4. Each layer was treated as a separate document object in JavaScript. The content could be included in the same file within the non-standard layer element (or any other element with the positioning set to "absolute" via CSS) or loaded from a separate file with <layer src="URL"> or <div src="URL">. It could also be generated via JavaScript with the layer = new Layer() constructor. The content would then be inserted into the layer with layer.document.write().
