div中的嵌套div不会覆盖

Question

I have a few nested divs, an outer, then a page wrapper and then two divs inside the page wraper. the two divs in there are generated and added to the page wrapper. if the 2 divs have the same top and left values the divs dont over lap but wrap below the previous div. attached is the code i have so far. i need the 2 divs in the page wrapper to not wrap like it is.

            }
#page-wrapper { width: 800px; height:700px; border:2px solid #ccc; padding: 0px; background-color:white; position:relative }

<div class="outer-container">

    $('#page-wrapper').append(thisdiv);
    idvalue= "div2"
thisdiv2 = '<div style="height:100;width:100;background-color:teal;top:2;left:2;z-index:1" id="'+idvalue+'" class="'+classvalue+'"></div>';
    $('#page-wrapper').append(thisdiv2);

Answer 1

If I understood it right you want the 2 generated divs to overlap? Just add position:absolute; to those divs.

And don't forget to put a unit (px) to your top/left/width/...
