Hello,
That is correct but the coding should be there by default. I just checked my older copy as well as the latest one and the code block is this:
#s5_center_area .module_round_box, #s5_component_wrap, #s5_center_area .moduletable, #s5_center_area .module_round_box-plain {
background:#ffffff;
padding:12px;
border:solid 1px #B2B1B1;
-moz-border-radius:8px;
-webkit-border-radius:8px;
border-radius:8px;
-webkit-box-shadow: 0 2px 0px rgba(0, 0, 0, 0.15);
-moz-box-shadow: 0 2px 0px rgba(0, 0, 0, 0.15);
box-shadow: 0 2px 0px rgba(0, 0, 0, 0.15);
}
