Summary: This will display diagonal shadows under each block (or it should) but I must warn this depends on the type of design the sideblocks are because these shadows would not look good on the default sidebar blocks or certain designed sideblocks.
The release is basically if you have the design that calls for it and you like it then upload the image into your /gradients folder and then paste then following to your EXTRA.CSS template
Code:
.sidebar .section:after {
background: url("@imagePath/xenforo/gradients/sidebar-shadow.png") no-repeat scroll center bottom transparent;
content: "";
position: relative;
display: block;
height: 30px; }
