This example is following the new flex-box syntax in the spec, right? How widespread is support for this? Might html5please.us need updating, dare I wonder? :D

Try This:
Give this CSS to the div which you have to centralize..

.class-name {
        margin: 0px;
	padding:0px;
	float: left;
	width:100%;
	position:absolute;
	top: 50%;
	transform: translateY(-50%) translateX(-50%);
	left:50%;
}
