Ciao pierca,
dividi questo css in due:
#leftcolumn h3, #rightcolumn h3 { background: url("../images/box_h3.png") no-repeat scroll left top transparent; color: #454545; font-family: Tahoma,Arial,Verdana,sans-serif; font-size: 11px; font-weight: bold; height: 36px; line-height: 36px; margin: 0 0 4px; overflow: hidden; padding: 0 11px; text-align: left; text-shadow: 1px 1px #EEEEEE; text-transform: uppercase; width: 190px;}
template.css (riga 869)
cosė:
#leftcolumn h3 { background: url("../images/box_h3.png") no-repeat scroll left top transparent; color: #454545; font-family: Tahoma,Arial,Verdana,sans-serif; font-size: 11px; font-weight: bold; height: 36px; line-height: 36px; margin: 0 0 4px; overflow: hidden; padding: 0 11px; text-align: left; text-shadow: 1px 1px #EEEEEE; text-transform: uppercase; width: 190px;}
e un altro per #rightcolumn h3
poi ad ognuno assegni l'immagine personalizzata.
