Accordion Tab border Colors

Hello guys,

how can I set the top border of the active tab? For hover and inactive works fine. I use this code:

/*------------Tab------------*/

.js_active .tab { border-top:5px #f1f1f1 solid;}

div .main_color .tabcontainer .active_tab_content, div .main_color .tabcontainer .active_tab {
background-color: #f1f1f1;
border: none !important; 
}

#top .main_color .tabcontainer .tab:hover {
background-color: #f1f1f1;
}

.main_color .template-archives .tabcontainer a, #top .main_color .tabcontainer .tab:hover, #top .main_color .tabcontainer .tab.active_tab {
color: #999999;
border-top:5px #0058a3 solid; 
}

div .main_color .tabcontainer .active_tab {
background-color: #f1f1f1; 
}

.main_color .tabcontainer .tab { 
background-color: #dddddd; 
 }
