Colonne 1 (gauche) : menu + titre « Espace Codage »

Browse files

Colonne 2 (milieu) : vide + barre en bas avec :

à gauche : + et trombone

au centre : barre de recherche / saisie

à droite : micro + flèche envoyer

Colonne 3 (droite) : panneau “Aperçu” avec une barre d’outils + message “Échec du chargement de l’aperçu.”

Copie-colle tout ça dans un fichier : espace-codage.html puis ouvre-le dans ton navigateur.
