Vertical Align an element in CSS

Dear experts, I was trying to align an paragraph to the middle of an division element via CSS and I somehow c开发者_JS百科an't get it to work.

 <style type="text/css">
    .wrap{
background:red;
height: 5em;  
     }
     p{
     background:blue; 
        height: 2em; 
vertical-align:middle; 

      }
  </style>


<div class="wrap">
    <p>
    ALIGN TEXT
    </p>
</div>

It doesn't work in IE nor firefox,

Here's a nice hackish example, i'd put the IE css in conditionals instead of hiding it with hacks, other that that nice.

  <div style="display: table; height: 400px; #position: relative; overflow: hidden;">
    <div style=" #position: absolute; #top: 50%;display: table-cell; vertical-align: middle;">
      <div class="greenBorder" style=" #position: relative; #top: -50%">
        any text<br>
        any height<br>
        any content, for example generated from DB<br>
        everything is vertically centered
      </div>
    </div>
  </div>

"Applies to: inline-level and 'table-cell' elements"

Alternatively you can use vertical-align:middle, display:inline-block, and an empty inline element with 100% height:

http://jsfiddle.net/HVtuD/ ​

<div id='container'>
  <div id='text'>vertical-align + inline-block<br>trick<br>in action</div>
</div>

#container{
  height: 300px;border: 1px solid black;text-align:center;
}
#text,#container:before{
  vertical-align: middle;
  display: inline-block;
}
  #container:before{
  content: "";
  height: 100%;
  width: 0%;
}

It's impossible to vertically align anything without it being a table, or without using Javascript.
