code js :
<script>
// objectif : pouvoir facilement modifier le contenu
// COLONNE 1 : USER CENTRIC
var titre_1="USERS CENTRIC";var link_1="#";var target_1="";
var label_1_1="Project Managers";var link_1_1="http://ocp.schneider-electric.com/Global/OCP/OCPHTML.nsf/pages/Project_Managers_Area/$File/ProjectManagers_home2.html";var target_1_1="";
...
</script>
Evidemment, c'est un code que je récupère, déjà un peu modifié (les coins arrondis) et j'ai fortement simplifié le html et le js, mais pas touché au CSS.
