a:Active

hi,

thank you for this great theme !!!
i would like the ACTIVE menu button (i.e. membres), the one which is of the page that I am actually looking at, to be of a different color.
I try to twink the theme like this:

a:active {
color: #f70264;
outline: none !important;
}

but eh.. not working :(… any ideas ? Thank you so much !

The page I need help with: [log in to see the link]
