Bonjour

je vous sollicite car je n'arrive pas a trouver sur quel élément agir pour différencier mes divs a resizé

voila j'ai fait un petit script de travail avec 3 div que je voudrais resizée vers la droite mais quand je sélectionne la deuxième ou troisième div, c’a me resize la première

je pense a un problème de css et de position absolu/relative...

Merci de votre aide
