I've Managed to make an extension to create a new style on the current document, then create a ID called #CenterContainer:

#CenterContainer {
position:absolute;
overflow:hidden;
top:50%;
left:50%;
width:348px; //calculates the height of selected element
height:104px; //calculates the width of selected element
margin-top:-52px; //calculates -half the height of selected element
margin-left:-174px; //calculates -half the width of selected element
}

if the element was placed in <div id="CenterContainer"></div> it would in turn be centered.

I need some help with the dreamweaver API side, trying to wrap <div id="CenterContainer"></div> around a selected element so it will b centered with 1 click.

So basically how do you wrap a div around a selected element, without the InsertDiv command that is already available, this is slighty different, because it creates a style aswell.

all help is appreicated!!
