Mam w global.css takie linijki:
/* Category Navigation */
#left_column div#categories_block_left h4{}
#left_column div#categories_block_left ul.tree li a,#left_column .block_content ul.bullet li a{background:#171717 url(../img/subnav.png); border-bottom:solid 1px #d1cfcf; padding:7px 0 7px 30px; color:#333; text-decoration:none; font-weight:bold; display:block; }
#left_column div#categories_block_left .block_content{padding:0px;}
Jak dodać do nich "hover{color:#999}"?
:-)
już sobie poradziłam :-)
