Na ja, so sollte es dann gehen:
Code
li.main_level_1 { margin-left: 1px; list-style: disc; }
li.main_level_1 a { padding: 0; font-weight: 900; }
li.main_level_2 { margin-left: 3px; list-style: square; }
li.main_level_2 a { padding: 0; font-weight: 500;}
li.main_level_3 { margin-left: 15px; list-style: circle; }
li.main_level_3 a { padding: 0; font-weight: 500;}
li.maincat, li.list { list-style: square; margin-top: 3px }
li.maincat a span { line-height: 18px; }
