/* We can use a general rule or just rely on nesting if DOM is nested. 
   Current PHP nesting: frontcat_render_cat_tree is recursive inside the item div? 
   Yes: echo '</div>'; is AFTER the recursive call.
   So .frontcat-sub-cat-list is inside .frontcat-cat-item.
   
   Structure:
   .item
     .header
     .sub-list
       .item
         .header
         .sub-list
   
   So padding-left on .sub-list or margin-left on .sub-list works recursively.
