Color Picker - Sélecteur de couleur

Il faut d'abord ajouter dans le CSS ( PA > Affichage > Couleurs > Feuille de style CSS ) ceci :

Code:

.colorpicker {
   width: 356px;
   height: 176px;
   overflow: hidden;
   position: absolute;
   background: url(http://tinyurl.com/colorpickerimg/colorpicker_background.png);
   font-family: Arial, Helvetica, sans-serif;
   display: none;
}
.colorpicker_color {

   position: absolute;
   background: #f00;
   overflow: hidden;
   cursor: crosshair;
}
.colorpicker_color div {

}
.colorpicker_hex {
   position: absolute;

   left: 282px;
}

   overflow: hidden;
}
.colorpicker_focus {
   background-position: center;
}
.colorpicker_hex.colorpicker_focus {
   background-position: bottom;
}
.colorpicker_submit.colorpicker_focus {
   background-position: bottom;
}
.colorpicker_slider {
   background-position: bottom;
}

Ensuite il suffit d'ajouter ce code javascript ici sur toutes les pages ( voir les codes javascript ).

Vous pouvez modifier ( hexadécimal ) sélectionnée par défaut à l'ouverture du sélecteur en changeant le :

Code:

"000000"
