sub, sup | NN 6 IE 4 DOM 1
The sub object reflects the sub element; the sup object reflects the sup element. Browsers tend to render these objects' content in a smaller size than surrounding content. IE 5 for Macintosh provides object-specific, read-only height and width properties for these elements, but no other object model does.
