Bonjour,

je réalise actuellement un site pour une société d'assurance.
J'ai réalisé un menu déroulant en CSS avec fontions javascript pour les onmouseover etc...

Le problème est que le rendu n'est pas du tout le même sous IE et sous FF (firefox). Sous Firefox il n'y a aucun problème, le menu appraît tel que je l'ai créé alors que sous IE l'espacement entre mes sous-menu est bien plus important ce qui implique des décalages dans ma découpe de maquette.

Pour illustrer ceci voici 2 screenshots :

Sous FF (affichage OK)


Sous IE (pb de décalage et espacement entre sous rubriques)


J'ai cherché un peu sur internet je n'ai pas trouvé d'infos spécifiques à mon problème.

Voici le code de ma page pour vous éclairer :

Code : Sélectionner tout - Visualiser dans une fenêtre à part
