Ce code me donne:
Cependant, je ne sais pas où ce cadre en arrière-plan vient de. Et aussi je voudrais avoir mes sous-titres centrée sur l'intrigue, pas la chose. Enfin je ne pouvais pas pour la vie de me faire ces parcelles ci-dessous les uns des autres dans un simple JPG. Comment puis-je résoudre ces problèmes?
