Before percentages, you probably need integers. Currently, you have
"1" or "all". I think it was deferred to Level 4.

This is not the intended behavior of column-span. A similar result can
be achieved with the implicit creation of grid and the use of grid
units in width.

Left is ignored for non-positioned boxes, and absolutely-positioned
boxes ignore float.
