One solution where we need not know the width/height of the dialog and then assume the margins.

Html:

<div id="dialog-contain">  <-- This div because I assume you might have a display that is not a flex. '
    <div id="block">
        <div id="centered">
            stuffs
        </div>
    </div>
</div>

Css:

#dialog-contain { // full page container.
    position: absolute;
    height: 100%;
    width: 100%;
    top: 0;
    left: 0;
    ...
}

#block {  // another container simply with display:flex.
    display: flex;
    height: 100%;
    width: 100%;
    justify-content: center;
}

#centered {   // another container that is always centered.
    align-self: center;
}

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>

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;

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.
