Voici le HTLM pour avoir un chemin d'étoiles au passage de la souris.

A mettre dans un article ou une page pour seulement le limiter.

(c'est le cas ici)

Pour tout le blog, l'insérer dans l'entête ou le pied de page.

Ne fonctionne qu'avec FireFox.

var colour="blue";    La couleur peut être changée

Guide couleur : ICI

copier l'Html "Ctrl C" et coller "Ctrl V"

Ne jamais mettre de javascript dans la CSS
