I've seen this post and after multiples attempts to modify the code by the top answer I am still unable to convert it from box-shadow Left/Bottom/Right to Top/Left/Bottom.
This is the Fiddle :
#shadowBox {
background-color: #ddd;
margin: 0px auto;
padding: 10px;
width: 220px;
box-shadow: 0px 8px 0 gray,
-10px 8px 0 gray, 10px 8px 0 gray;
}
<br/><br/>
<div id="shadowBox">Test</div>
How can I do that ? I don't understand how this works and manuals don't go further than the classic border-box...
