jquery - 从许多背景图像中动画化一个背景图像

Question

我已经在 CSS 中实现了 2 个背景图像，以根据 Photoshop 布局获得混合模式样式。我也猜对了。但现在我只想为其中的一张图片制作动画。

.home
    background:
      image: url(/image/XZDsP.jpg), url(https://img.clipartfest.com/d840c9cfc1786dc7013443ac7638dde0_halloween-clip-art-free-spider-spider-web-clipart-png_500-463.png)
      blend-mode: color-dodge
      repeat: no-repeat
      size: cover, contain
      position: 0, center
    height: 100vh

你们知道怎么做吗？

只需定义另一个类分配给新的<div>在你的<section>

试试这个。

<section class="home">
    <div class="rotating"></div>
</section>

定义这个CSS

/* rotation animation */
@-webkit-keyframes rotate {
  from { -webkit-transform:rotate(0deg); }
  to { -webkit-transform:rotate(360deg); }
}

@-moz-keyframes rotate {
  from { -moz-transform:rotate(0deg); }
  to { -moz-transform:rotate(360deg); }
}

@-ms-keyframes rotate {
  from { -ms-transform:rotate(0deg); }
  to { -ms-transform:rotate(360deg); }
}

@-o-keyframes rotate {
  from { -o-transform:rotate(0deg); }
  to { -o-transform:rotate(360deg); }
}

.rotating {
  position:absolute;
  width:100%;
  height:100%;
  background-image: url(https://img.clipartfest.com/d840c9cfc1786dc7013443ac7638dde0_halloween-clip-art-free-spider-spider-web-clipart-png_500-463.png);
  -webkit-transform-origin: 50% 50%;
  -webkit-animation-name: rotate;
  -webkit-animation-duration: 1.5s;
  -webkit-animation-iteration-count: infinite;
  -webkit-animation-timing-function: linear;
  -moz-transform-origin: 50% 50%;
  -moz-animation-name: rotate;
  -moz-animation-duration: 1.5s;
  -moz-animation-iteration-count: infinite;
  -moz-animation-timing-function: linear;
  -ms-transform-origin: 50% 50%;
  -ms-animation-name: rotate;
  -ms-animation-duration: 1.5s;
  -ms-animation-iteration-count: infinite;
  -ms-animation-timing-function: linear;
  -o-transform-origin: 50% 50%;
  -o-animation-name: rotate;
  -o-animation-duration: 1.5s;
  -o-animation-iteration-count: infinite;
  -o-animation-timing-function: linear;
}
