Just a nice visual reference of CSS box shadows I like to use from time to time.
box-shadow: 0 0 5rem 0 rgba(0,0,0,0.1);
box-shadow: 0 1 3rem rgba(0,0,0,0.05);
box-shadow: 0 1px 5px rgba(0,0,0,0.15);
border-bottom: 1px solid rgba(0, 0, 0, 0.2); box-shadow: 0 1px 5px rgba(0, 0, 0, 0.15);
box-shadow: 0 0.5px 0 0 #ffffff inset, 0 1px 2px 0 #B3B3B3;
box-shadow: 0 3px 20px rgba(28,49,70,.08), 0 1px 2px rgba(28,49,70,.04);
