Bonjour

je suis actuellement en étude de graphiste/WebDesigner en alternance
et personne ne s'y connait assez pour me répondre dans ma boite.
Alors je viens vous voir en espérant trouver la solution.


je suis en charge de la création des Newsletters du site e-commerce que je m'occupe sauf que je n'arrive pas à résoudre mon problème de marge.
sur mon Pc tout s'affiche correctement
sauf que après l'envoie de la News sur certaines plateforme mail ou certains navigateurs des marges horizontales apparaissent sans que j'arrive à savoir pourquoi...
La newsletter est du coup complètement déformé et très moche



prévisualisation de Gmail

je fonctionne sous Outlook 2003 et tout fonctionne toujours très bien
j'ai aussi fait quelques tests sous Gmail et hotmail pour prendre des exemples
Avec IE8
Gmail : fonctionne pas
Hotmail :fonctionne
Avec Firefox 3.6
Gmail : fonctionne pas
Hotmail :fonctionne pas
Avec Chrome 9
Gmail : fonctionne pas
Hotmail :fonctionne pas

un lien vers ma newsletter hébergé pour une prévisualisation
cliquez ici

voila mon code Newsletter
