Layer (HTML tag)

Layer (HTML tag)

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 either included in the same file within the non-standard <layer> tag (or any other tag with the positioning set to "absolute" via CSS, loaded from a separate file with <layer src="URL HERE"> or <div src="URL HERE">, or generated via JavaScript with the new Layer(), the content would then be filled with "layer".document.write().

In modern browsers, this functionality is provided by using an absolutely-positioned div, or, for loading the content from an external file, an IFrame.
