Layers is a paint program concept. HTML and CSS don't have "layers" so just what exactly are you even on about?
The CSS layers refer to applying the z-index property to elements that overlap with each other. The z-index property is used along with the position property to create an effect of layers. You can specify which element should come on top and which element should come at bottom.
