well for side bar links is :

somewhere in your stylevars something got messed up , but you can place that code in some additional CSS file, i recommend overwriting VARS for customization , you have more control and its easier to change.
just create a file mycss.css , place it anywhere , then just link it , but put it on the common templates at the TOP of the HEADER template code, so it comes after all VARS..
