bonjour,
je souhaite modifier une light box en mettant le bouton close en haut a gauche , plutot qu'en bas.
Ainsi, quand une image est plus grande que la fenetre du navigateur, c'est intuitif pour fermer la lightbox, plutot que faire defiler vers le bas
je ne sais s'il faut modifier la css (j'ai bidouillé sans succès) ou le .css
voici les deux fichiers que j'utilise :
merci pour toute aide
cyril
lightbox.css
