.. even though you havent’t yet hovered over the link.
This change corrects that behavior. Suggested by mina86:
<mina86> so when you hover over the LI the link changes background even though
you havent’t yet hovered over the link
<mina86> #container #sidebar li:hover a { background: #577632; color: #fff; }
<mina86> s/li:hover a/li a:hover/ would be IMO better
