You can do this with anything in HTML, using absolute positioning: set 
just one of the coordinates in each direction, and leave the other on 
'auto'. As in:

   div { position: absolute: bottom: 10em; right: 10em; width: auto;
         height: auto; left; auto; top: auto; margin: 0; }

Things that are impossible just take longer.   `._.-(,_..'--(,_..'`-.;.'
