Answer 1

For the parent: display: table;

For the child: display: table-cell;

Then add vertical-align: middle;

I can make a fiddle but home time now, yay!

OK here is the lovely fiddle: http://jsfiddle.net/lharby/AJAhR/

.parent {
   display:table;
}

.child {
   display:table-cell;
   vertical-align:middle;
   text-align:center;
}
