html - 在 CSS 中旋转地球

Question

我正在 CSS 中创建一个旋转的地球效果。我用 CSS 创建了地球:

body {
  background-color: #111;
}

#earth {
    width: 300px;
    height: 300px;
    background: url(https://web.archive.org/web/20150807125159if_/http://www.noirextreme.com/digital/Earth-Color4096.jpg);
    border-radius: 50%;
    background-size: 610px;
    box-shadow: inset 8px 36px 80px 36px rgb(0, 0, 0),
    inset -6px 0 12px 4px rgba(255, 255, 255, 0.3);
    animation-name: rotate;
    animation-duration: 12s;
    animation-iteration-count: infinite;
    animation-timing-function: linear;
    -webkit-animation-name: rotate;
    -webkit-animation-duration: 12s;
    -webkit-animation-iteration-count: infinite;
    -webkit-animation-timing-function: linear;
}

@keyframes rotate {
    from { background-position: 0px 0px; }
    to { background-position: 500px 0px; }
}
@-webkit-keyframes rotate {
    from { background-position: 0px 0px; }
    to { background-position: 500px 0px; }
}

<div id="earth"></div>

但它停止了，然后图像重置并重新开始。我希望它平稳移动而不会抽搐。非常感谢!

在background-position: 500px 0px;中将500px替换为610px，即background-size

body {
  background-color: #111;
}
#earth {
  width: 300px;
  height: 300px;
  background: url(https://web.archive.org/web/20150807125159if_/http://www.noirextreme.com/digital/Earth-Color4096.jpg);
  border-radius: 50%;
  background-size: 610px;
  box-shadow: inset 8px 36px 80px 36px rgb(0, 0, 0), inset -6px 0 12px 4px rgba(255, 255, 255, 0.3);
  animation-name: rotate;
  animation-duration: 12s;
  animation-iteration-count: infinite;
  animation-timing-function: linear;
  -webkit-animation-name: rotate;
     -webkit-animation-duration: 12s;
     -webkit-animation-iteration-count: infinite;
     -webkit-animation-timing-function: linear;
}
@keyframes rotate {
  from {
    background-position: 0px 0px;
  }
  to {
    background-position: 610px 0px;
  }
}
@-webkit-keyframes rotate {
  from {
    background-position: 0px 0px;
  }
  to {
    background-position: 610px 0px;
  }
}

<div id="earth"></div>
