Thank you. it works perfectly.
I have one more question: we want to colorize 2 or 3 buttons on the map. How to proceed to get a button of a different color ?
the code below:
<style type="text/css">
.page{background: url(/graphics/carte/Marseille.png) no-repeat;max-width: 1280px;height: 700px;}
.radiobox {background: url(/graphics/radiobutton_unselected2.png) no-repeat center center;}
.graphical_select radiobox {background: url(/graphics/radiobutton_selected2.png) no-repeat center center;}
.radiobox, .graphical_select radiobox {width: 30px;height: 30px;}
#Q7_location_1_graphical{position:relative; top:30px;right: 75px;}
