Question

我试图在我的网站上获取图像的3D包装效果。 3D包装类似于image

中的包装

我需要的效果与图像

完全相同

以下是我目前使用的纯CSS。

.gallery-wrap{
    background-color: rgba(0,0,0,0);
    -webkit-box-shadow: 0 0px 0px 0px black !important;
    -moz-box-shadow: 0 0px 0px 0px black !important;
    box-shadow: 0 0px 0px 0px black !important;
  }
  .gallery-wrap img{
    transform: perspective(400px) rotateY(10deg) translateX(7.5%) translateY(30px);
    margin-bottom: 5em !important;
    background-color: rgba(0,0,0,0);
    -webkit-box-shadow: 0 5px 7px -1px black;
    -moz-box-shadow: 0 5px 7px -1px black;
    box-shadow: 0 5px 7px -1px black;
  }
  .gallery-wrap div:after{
    content: '';
    width: 5%;
    height: 96%;
    background-image: url('<url of the same image the is to be wrapped>');
    position: absolute;
    top: 0px;
    transform: perspective(250px) rotateY(-55deg) translateY(7px) translateX(-10px);
    left: 0px;
    background-size: 10% 750%;
    background-position-x: 0%;
  }

代码有效，但问题是它并不适用于所有图像。高度大于宽度的图像将生成上述代码。

我想知道是否有人能用JS算法帮助我/指向现有的（最好是免费的）js这样做。该算法应捕获img元素的宽度和高度，然后为上述代码渲染transform值。

想出来。代码如下

.gallery-wrap{
    perspective: 1000px;  //required to get the correct 3D depth
}
.gallery-wrap div:after{
    content: '';
    position: absolute;
    left: 0;
    bottom: 0;
    width: 36px;
    height: 100%;
    background: inherit;
    background-size: cover, cover;
    background-position: left; //This and the next 2 lines are for left edge. Change bottom/top/right accordingly
    transform: rotateY(90deg); // Y is the Axis of rotation. Change accordingly. 90deg will flip (mirror) the image
    transform-origin: left; // Which side to be flipped
}
.gallery-wrap div {
    display: block;
    height: 100%;
    background: linear-gradient(rgba(0, 0, 0, 0.4), rgba(0, 0, 0, 0.4)), url("<image_link>"); // Just to add a gradient effect to the farther side
    background-size: 0, cover;  //To get the gradient effect
    transform-style: preserve-3d;
    transition: all 0.5s;
    margin: 10% auto; // This and the next line 2 line are dimension adjustments
    width: 80%;
    transform: rotateY(37.5deg); // This is for the main image rotation
    transform-origin: center; // This is for point of origin of the transform. Use center for the best effect;
}

图像必须用作背景图像。
