将图像从前视图旋转到具有 3D 效果的左视图

Question

我正在使用下面的代码来旋转图像，但我只能实现将图像从正面旋转到底部视图。我想将图像从前视图旋转到左视图。我怎样才能做到这一点？

body {
  height: 100vh;
  margin: 0;
}

.thumb {
  width: 600px;
  height: 400px;
  perspective: 1000px;
}

.thumb a {
  display: block;
  width: 100%;
  height: 100%;
  background: linear-gradient(rgba(0, 0, 0, 0.4), rgba(0, 0, 0, 0.4)), url("https://i.imgur.com/9NVqw8Q.jpg");
  background-size: 0, cover;
  transform-style: preserve-3d;
  transition: all 0.5s;
}

.thumb:hover a {
  transform: rotateX(80deg);
  transform-origin: bottom;
}

.thumb a:after {
  content: '';
  position: absolute;
  left: 0;
  bottom: 0;
  width: 100%;
  height: 36px;
  background: inherit;
  background-size: cover, cover;
  background-position: bottom;
  transform: rotateX(90deg);
  transform-origin: bottom;
}

.thumb a:before {
  content: '';
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background: rgba(0, 0, 0, 0.5);
  box-shadow: 0 0 100px 50px rgba(0, 0, 0, 0.5);
  transition: all 0.5s;
  opacity: 0.15;
  transform: rotateX(95deg) translateZ(-80px) scale(0.75);
  transform-origin: bottom;
}

.thumb:hover a:before {
  opacity: 1;
  box-shadow: 0 0 25px 25px rgba(0, 0, 0, 0.5);
  transform: rotateX(0) translateZ(-60px) scale(0.85);
}

<div class="thumb">
  <a href="#"></a>
</div>

Answer 1

修改rotateX to rotateY，因为左视图使用垂直轴。
修改transform-origin为left，因为我们是以左边为旋转点进行变换
如 @kaiido 所述，将类似的更改应用于 3D 外观的伪元素。我已经评论了所做的更改。

body {
  height: 100vh;
  margin: 0;
}

.thumb {
  width: 600px;
  height: 400px;
  perspective: 1000px;
  margin: 100px; /* For snippet spacing */
}

.thumb a {
  display: block;
  width: 100%;
  height: 100%;
  background: linear-gradient(rgba(0, 0, 0, 0.4), rgba(0, 0, 0, 0.4)), url("https://i.imgur.com/9NVqw8Q.jpg");
  background-size: 0, cover;
  transform-style: preserve-3d;
  transition: all 0.5s;
}

.thumb:hover a {
  transform: rotateY(45deg); /* 1 - From rotateX */
  transform-origin: left; /* 2 - From bottom */
}

.thumb a:after {
  content: '';
  position: absolute;
  left: 0px;
  bottom: 0;
  width: 36px; /* Interchanged width and height because horizontal transformation is now vertical transformation */ 
  height: 100%;
  background: inherit;
  background-size: cover, cover;
  background-position: bottom;
  transform: rotateY(90deg); /* 1 - From rotateX */
  transform-origin: left; /* 2 - From bottom */
}

.thumb a:before {
  content: '';
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background: rgba(0, 0, 0, 0.5);
  box-shadow: 0 0 100px 50px rgba(0, 0, 0, 0.5);
  transition: all 0.5s;
  opacity: 0.15;
  transform: rotateY(15deg) translateZ(-40px) scale(0.75); /* 3 - From rotateX */
  transform-origin: bottom;
}

.thumb:hover a:before {
  opacity: 1;
  box-shadow: 0 0 25px 25px rgba(0, 0, 0, 0.5);
  transform: rotateY(0) translateZ(-60px) scale(0.85); /* 3 - From rotateX */
}

@manoj-kumar 是对的。利用 rotateX 到 rotateY

您还必须为 :after 设置 transform-origin 和 position 以使其在左侧换行

.thumb {
  margin: 100px;
  width: 600px;
  height: 400px;

.thumb a {
  display: block;

  background-size: 0, cover;
  transform-style: preserve-3d;
  transition: all 0.5s;
}

.thumb:hover a {
  transform: rotateY(60deg);
  /* From rotateX */
  transform-origin: left;
  /* From bottom */
}

.thumb a:after {
  content: '';
  position: absolute;
  left: 0;
  bottom: 0;
  width: 30px;
  height: 100%;
  background: inherit;
  background-size: cover, cover;
  background-position: bottom;
  transform: rotateY(110deg);
  transform-origin: left;
  /* extra */
  border-top-right-radius: 3px;
  border-bottom-right-radius: 3px;
}

.thumb a:before {
  content: '';
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background: rgba(0, 0, 0, 0.5);
  box-shadow: 0 0 100px 50px rgba(0, 0, 0, 0.5);
  transition: all 0.5s;
  opacity: 0.15;
  transform: rotateX(15deg) translateZ(-40px) scale(0.75);
  transform-origin: bottom;
}

.thumb:hover a:before {
  opacity: 1;
  box-shadow: 0 0 25px 25px rgba(0, 0, 0, 0.5);
  transform: rotateX(0) translateZ(-60px) scale(0.85);
