Answer 1

Well you can do even ever shorter :P ( because the cell behaviour maximize already its dimensions in regards of its parent/container ):

html { display:table; width:100%; height:100%; }
body { display:table-cell; text-align:center; vertical-align:middle; }

And obviously, you can adapt these rules to others html elements ;)

Answer 2

Try this:

html, body { width:100%; height:100%; }
html { display:table; }
body { display:table-cell; text-align:center; vertical-align:middle; }

( in your css rules )
