If you’re talking about lining them up “horizontally” you just need to remove the top margin on the sidebar. Take a look around line 1846 or search for “.s {” in your css for this –
.s {
border-radius: 3px;
-moz-border-radius: 3px;
-webkit-border-radius: 3px;
box-shadow: inset 0 1px 1px 1px #eee;
-moz-box-shadow: inset 0 1px 1px 1px #eee;
-webkit-box-shadow: inset 0 1px 1px 1px #eee;
background: #fff;
margin: 0;
padding: 5px 5px 7px 12px;
width: 170px;
}
Notice I changed the margin to “0”.
