This is _never_ possible. A block-level element remains a block-level
element, regardless of the CSS rules you apply to it. CSS only affects
the rendering, it doesn't change the element type.

No. The rendered result might look the same, but the elements are still
completely different and have to follow the rules of the DTD.
