How can I separate 2 sidebar blocks from each other using a separator (space)?

[vexxy]

sorry for the so late response, but my left border thing seems unresolved atm...i tried rmoveing all moz-shadow styles, wtih no luck...here's the code I Have, maybe i'm missing something:

#sidebar_container .underblock {background: transparent; height: 20px;}
#sidebar_container > ul {
    -moz-border-radius:0px;
    -webkit-border-radius:: 0px;
    -moz-box-shadow: none;
    background:transparent !important;
    border:none !important;
}
#sidebar_container .block {
    background-color:{vb:stylevar forum_sidebar_background.backgroundColor};
    -moz-border-radius:{vb:stylevar border_radius}; /* border_radius */
    -webkit-border-radius: {vb:stylevar border_radius}; /* border_radius */
    -moz-box-shadow: -2px 2px 2px  {vb:stylevar shadow_color};
}

again sorry for the late reply..and I appreciate your support
