.popup-content-box{

You can use CSS3 'transform':

CSS:

.popup-bck{
  background-color: rgba(102, 102, 102, .5);
  position: fixed;
  width: 100%;
  height: 100%;
  top: 0;
  left: 0;
  z-index: 10;
}
.popup-content-box{
  background-color: white;
  position: fixed;
  top: 50%;
  left: 50%;
  z-index: 11;
-webkit-transform: translate(-50%, -50%);
-moz-transform: translate(-50%, -50%);
-ms-transform: translate(-50%, -50%);
-o-transform: translate(-50%, -50%);
transform: translate(-50%, -50%);
}

HTML:

<div class="popup-bck"></div>
<div class="popup-content-box">
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. 
</div>

*so you don't have to use margin-left: -width/2 px;

I write a code in jquery. It isnt seen an easy way. But i hope it is useful for you.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<style type="text/css">

.popup{
    border: 4px solid #6b6a63;
    width: 800px;
    border-radius :7px;
    margin : auto;
    padding : 20px;
    position:fixed;
}

</style>

<div id="popup" class="popup">
some lengthy text<br>
some lengthy text<br>
some lengthy text<br>
some lengthy text<br>
some lengthy text<br>
some lengthy text<br>
some lengthy text<br>
some lengthy text<br>
</div>

<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script>
$(document).ready(function(){
    var popup_height = document.getElementById('popup').offsetHeight;
    var popup_width = document.getElementById('popup').offsetWidth;
    $(".popup").css('top',(($(window).height()-popup_height)/2));
    $(".popup").css('left',(($(window).width()-popup_width)/2));
});
</script>

Note: This does not directly answer your question. This is deliberate.

A List Apart has an excellent CSS Positioning 101 article that is worth reading ... more than once. It has numerous examples that include, amongst others, your specific problem. I highly recommend it.

I need to position div popup to the center of browser screen ( no matter what size the screen is). And I want to keep the position as absolute as I don't want to move the popup down when I scroll down the page.

This div is displayed when button is clicked using Jquery.

I tried setting margin-left to half of the width like mentioned in other posts but It isn't working for me.

Here is my code

CSS code:

.holder{        
    width:100%;
    position:absolute;
    left:0;
    top:0px;
    display:block;  
}
.popup{
    width:800px;
    margin:0 auto;
    border-radius: 7px;
    background:#6b6a63;
    margin:30px auto 0;
    padding:6px;
}

.content{
    background:#fff;
    padding: 28px 26px 33px 25px;
}

HTML Code:

  <div class="holder">
        <div id="popup" class="popup">            
            <div class="content">
                        some lengthy text
                     </div>
        </div>
   </div>

Thanks!!
