Tutorial Description - Layers are DHTML components and are similar to tables with a few different properties. Like tables they are containers where you put text or images. Unlike tables layers allow you to position an image or text in a particular point on the page and dreamwever automatically derives the x and y coordinates for the layer. You can reposition the layer by selecting and dragging it on the screen. Layers can be hidden or made visible, this is an added advantage in layers. Layers are viewed differently in different browsers.
