 If text-shadow is supported, color is set to white and the text-shadow keeps it legible.  If not, the entire second block is ignored, and color is set to black.

 In this example, if a browser supports Template Layout, the later `position` values override the previous values of "absolute" (and the left/top/right values are thus ignored), and the page is laid out according to the Template Layout spec.  If the browser doesn't support Template Layout, though, then the entire @supports block is ignored, and the previous absolute positioning takes effect instead.
