html - How do I vertically align text in a div?

I am trying to find the most effective way to align text with a div. I have tried a few things and none seem to work.

.testimonialText {
  position: absolute;
  left: 15px;
  top: 15px;
  width: 150px;
  height: 309px;
  vertical-align: middle;
  text-align: center;

  font-family: Georgia, "Times New Roman", Times, serif;
  font-style: italic;
  padding: 1em 0 1em 0;
}

Vertical Centering in CSS

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

Article summary:

For a CSS 2 browser, one can use display:table/display:table-cell to center content.

A sample is also available at JSFiddle:

div { border:1px solid green;}

  

    

      everything is vertically centered in modern IE8+ and others.
    
  

It is possible to merge hacks for old browsers (Internet Explorer 6/7) into styles with using # to hide styles from newer browsers:

div { border:1px solid green;}

  
    "#position: absolute; #top: 50%;display: table-cell; vertical-align: middle;">
    

      everything is vertically centered
