J'ai fait une petite tentative d'utiliser le glisser-déplacer avec CSS3. La capture d'écran est la suivante :
.Les amis qui connaissent l'effet glisser devraient connaître la méthode consistant à faire glisser vers la gauche et la droite après avoir maintenu la souris enfoncée.
Cette petite démo tente d'appliquer des points de connaissances pertinents en CSS3 à l'affichage d'images,
Lorsque vous faites glisser l'image, elle affichera une sensation tridimensionnelle ~~
Le code direct est le suivant :
#list{ width:400px; height:440px; margin:30px auto 30px; position:relative;z-index:500;} #list li{height:40px;width:400px; position:relative;cursor:pointer;-webkit-perspective:800px; } #list li div{height:40px;width:400px; -webkit-transform-style:preserve-3d;-webkit-backface-visibility:hidden;position:relative;-webkit-transform:translateZ(-200px);-webkit-transform:50ms all linear;} #list span{height:40px; width:400px; position:absolute;left:0;top:0; overflow:hidden;} #list div span:nth-child(1){background:url(img/1.jpg) no-repeat; -webkit-transform:translateZ(200px);} #list div span:nth-child(2){background:url(img/2.jpg) no-repeat;-webkit-transform-origin:right;-webkit-transform:translateZ(200px) rotateY(-90deg); } #list div span:nth-child(3){background:url(img/3.jpg) no-repeat;-webkit-transform-origin:right;-webkit-transform:translateZ(-200px); } #list div span:nth-child(4){background:url(img/4.jpg) no-repeat;-webkit-transform-origin:left;-webkit-transform:translateZ(200px) rotateY(90deg); } #list em{ width:400px;height:400px; position:absolute;left:0;background:#666;} #list li em:nth-of-type(1){-webkit-transform-origin:top;-webkit-transform:translateZ(200px) rotateX(-90deg); top:0;} #list li em:nth-of-type(2){-webkit-transform-origin:bottom;-webkit-transform:translateZ(200px) rotateX(90deg); bottom:0;} #list li:nth-last-child(1){ z-index:10;} #list li:nth-last-child(2){ z-index:20;} #list li:nth-last-child(3){ z-index:30;} #list li:nth-last-child(4){ z-index:40;} #list li:nth-last-child(5){ z-index:50;} #list li:nth-last-child(6){ z-index:60;} #list li:nth-child(2) span{ background-position:0 -40px;} #list li:nth-child(3) span{ background-position:0 -80px;} #list li:nth-child(4) span{ background-position:0 -120px;} #list li:nth-child(5) span{ background-position:0 -160px;} #list li:nth-child(6) span{ background-position:0 -200px;} #list li:nth-child(7) span{ background-position:0 -240px;} #list li:nth-child(8) span{ background-position:0 -280px;} #list li:nth-child(9) span{ background-position:0 -320px;} #list li:nth-child(10) span{ background-position:0 -360px;} #list li:nth-child(11) span{ background-position:0 -400px;} #btns{ width:130px; margin:0 auto;} #btns li{ width:20px;height:20px;background:#fff; font-size:14px; font-weight:bold; text-align:center; line-height:20px; float:left; color:#f60; margin:0 3px; cursor:pointer;} #btns .active{ background:#f60;color:#fff;}
