vertical centering in css
http://www.jakpsatweb.cz/css/css-vertical-center-solution.html

article summary:

for css2 browser 1 can use display:table/display:table-cell center content.

sample available @ jsfiddle:

  <div style="display: table; height: 400px; overflow: hidden;">      <div style="display: table-cell; vertical-align: middle;">        <div>          vertically centered in modern ie8+ , others.        </div>      </div>    </div>

it possible merge hacks old browser (ie6/7) styles using # hide styles newer browsers:

<div style="display: table; height: 400px; #position: relative; overflow: hidden;">   <div style=     " #position: absolute; #top: 50%;display: table-cell; vertical-align: middle;">     <div style=" #position: relative; #top: -50%">      vertically centered     </div>   </div> </div>
