"Layers" is a feature of HTML and CSS that allows content that is arranged logically in a document to be displayed visually in another layout. There are layer codes (z-index) that determine which layer is on top, and which is under. By setting the z-index, presentation order can be changed. In the background, layers are created using the <div></div> markup, which will be ignored by many types of assistive technologies. This is what allows accessible pages to be created with layers - they can be invisible to those who need access. However, because the visual presentation is not necessarily the same as the logical presentation, it is critical that a page designed with layers be constructed so that, with the layers turned off, the page makes sense. This is where many designers can mess things up. The page should be designed first so that the content is in logical order, then the layers used to provide the desired visual presentation, with the awareness that not everyone will see the "visual" order.
