How can I make an inset shadow span the whole page with absolute positioned elements in it?












1















I am working on a page which has an inset box shadow on its body element. There are absolute and relative positioned divs on the page which can get big enough that a scrollbar appears to fully show them. The box shadow will then be cut off even at 100% or 100vh height. Is there a way to make the box shadow always span the whole page, even if a div makes it larger? Interestingly the background does continue below the normal viewport.



I have tried all the various shennanigans with height min-height on the html and body tag but to no avail.



Here is a dumbed down snippet that shows the problem: https://jsfiddle.net/6ay8rusf/1/



body{
margin: 0;
background-color:#333;
box-shadow: inset 0 0 35px rgba(0,0,0,0.3);
min-height: 100vh;
height: 100%;
}
.abs{
left: 50%;
top: 50px;
width: 50px;
height: 100vh;
position: absolute;
background-color: #fff;
margin-bottom: 20px;
}


I hope to have the inset shadow span the whole page and not be cut off at 100vh;
