CSS Swag: Multi-Column Lists. One of the minor holy grails of XHTML and CSS is to produce a single, semantically logical ordered list that wraps into vertical columns.
The ideal situation, in my view, would be a single XHTML list whose wrapping is controlled entirely by CSS. Further, the wrapped list should tolerate text resizing (easily accomplished by styling everything in ems).

Let's move div-1 down 20 pixels, and to the left 40 pixels: Notice the space where div-1 normally would have been if we had not moved it: now it is an empty space.
