Observateur de requêtes média de l’espace de démonstration
Dans un scénario d’espace de présentation, créez un observateur de requêtes média : avec du contenu réel, des contrôles actionnables, un retour d’état clair et une mise en page adaptée à toutes les tailles.
Après activation de JavaScript, ce cas peut être modifié, exécuté et enregistré. Code source fixe ci-dessous :
