Bonjour,
J'aimerais réaliser un document dont chaque exercice soit dans un box et tous les box des exercices soient dans un autre box. Mon problème est que le deuxième exercice saute dans la page suivante, alors qu'il existe de l'espace dans la page en cours. L'image ci-dessous résume mon problème.



Et voici un exemple de mon code:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

J'espère que tu y trouveras ton bonheur ;p
