Try to change these (I customized it, so make your changes): .tabberlive > .tabbertab:not(.tabbertabhide){ border: none; } .tabberlive > .tabbernav { border: none; margin-top:3px; font-family: RobotoCondensed-Bold, 'Roboto Condensed', sans-serif; font-size: 1rem; text-shadow: 0 1px 2px rgba(0,0,0,0.3); } .tabberlive > .tabbernav > li > a { color: #ccc; background-color: #0075b9; border: 3px solid rgba(0,0,0,0.2); border-radius: 3px 3px 0 0; border-bottom: none; } .tabberlive > .tabbernav > li > a:hover { color: #fff; background-color: #009CF6; border: 3px solid rgba(0,0,0,0.2); border-bottom: none; } .tabberlive > .tabbernav > li.tabberactive > a { color: #fff; background-color: #009CF6; border: 3px solid rgba(0,0,0,0.2); border-bottom: none; } .tabberlive > .tabbernav > li.tabberactive > a:hover { background-color: #009CF6; } Ps: delete the old code before testing this. If any code should not work try adding !important, for example:

I hope this will work XD
