Bonjour,

J'aimerai placer mon bouton "Envoyer" sur mon image à droite, comment faire ?

Merci !

Jujudufoot.

Tu veux superposer le bouton sur l'image ?

Salut l'ami,

Plusieur possibilité s'offre a toi 😀


tu peu lui mettre un float: right;
tu peu lui mettre un margin-left: 97%; (mais tu va avoir une petite marge)

Dans les deux cas, ça va bouger ton bouton a droite 😉

ah j'avais pas vu que tu la voulais dans l'image !
Laisse moi 3 minutes le temps de m'occupé d'un monstre  de 3,5ans et j'arrive

Tiens, tu peu essayé ça 😀

         <style> // remplacer la balise style dans ton fichier style.css 😀
            body {
                background-size: 100%; // va prendre la totalité de ton body
                background-image: url(img/fond-accueil.jpg); // cherche la source de l'image
                background-repeat:no-repeat; // Ne va pas répété l'image
            }
            .accueil-bouton {
                position: absolute;
                right: 0; // va se coller a 0 pixel du bord de droit
                bottom: 0; // va se coller a O pixxel du bas de page
            }
          </style>
    </head>
    <body>
        <div class="accueil-haut">
           <div class="accueil-bouton">
               <input type="submit" name="inscription" value="je m'inscris" >
            </div>
      </div>  
    </body>

Merci, mais le bouton n'est pas superposé, il est en bas à droite de l'image, je voudrais aussi que mon image s'agrandisse et rétrécisse quand j'étire la fenêtre, pour le moment elle ne fais que grandir !

Je peux te conseiller d'utiliser la fonction css "z-index" je ne m'y connais pas trop mais je peux peut être te donner un code je ne sais pass si il marchera mais bon, on a rien sans rien:
