In case you are using your own renderer, you are responsible for the layout, for instance:
- a parent div to set the element size - this is were you would want to apply borders, padding, backgrounds, etc.
- a viewport div that fills it parent and has "position: relative" and "overflow: hidden"
- this is to ensure a correct sizing of the renderer when the parent div is resized
- the div that will hold your renderer, that fills its parent
