Question

我正在尝试使SVG的高度具有响应性，在网上查看后，我发现可以尝试将其添加到SVG中：

window.addEventListener('beforeunload', function (e) { /* your pushState */ });

但是，当我在手机上查看SVG时，或者直到找到页面底部的一定距离时，这对我不起作用，我该怎么做，以便无论高度如何，图像都显示在正确的位置？

width="100%" height="100%" preserveAspectRatio="xMinYMin meet"

#home {
  height: 100vh;
  overflow: hidden;
}
#background {
  fill: white;
  stroke: none;
  transform-origin: 1270px 550px;
  -webkit-animation: fillbackground 2s linear 2s forwards;
  animation: fillbackground 2s linear 2s forwards;
}
@keyframes fillbackground {
  from {
    transform: scale(1);
  }
  to {
    transform: scale(4);
  }
}
@-webkit-keyframes fillbackground {
  from {
    transform: scale(1);
  }
  to {
    transform: scale(4);
  }
}
#middleground {
  -webkit-animation: addclip 0s linear 2s forwards;
  animation: addclip 0s linear 2s forwards;
}
@keyframes addclip {
  to {
    clip-path: url(#art);
  }
}
@-webkit-keyframes addclip {
  to {
    clip-path: url(#art);
  }
}
#foreground {
  fill: none;
  stroke: #fff;
  stroke-width: 10px;
  stroke-dasharray: 1028px;
  -webkit-animation: dash 2s;
  animation: dash 2s;
}
@keyframes dash {
  from {
    stroke-dashoffset: 1028px;
  }
  to {
    stroke-dashoffset: 0px;
  }
}
@-webkit-keyframes dash {
  from {
    stroke-dashoffset: 1028px;
  }
  to {
    stroke-dashoffset: 0px;
  }
}

在CSS下方给出您的svg图像，您就完成了...

svg {
    position: absolute;
    left: 0;
    bottom: 0;
    height: auto;
}

svg {
    position: absolute;
    left: 0;
    bottom: 0;
    height: auto;
}
#home {
  height: 100vh;
  overflow: hidden;
}
#background {
  fill: white;
  stroke: none;
  transform-origin: 1270px 550px;
  -webkit-animation: fillbackground 2s linear 2s forwards;
  animation: fillbackground 2s linear 2s forwards;
}
@keyframes fillbackground {
  from {
    transform: scale(1);
  }
  to {
    transform: scale(4);
  }
}
@-webkit-keyframes fillbackground {
  from {
    transform: scale(1);
  }
  to {
    transform: scale(4);
  }
}
#middleground {
  -webkit-animation: addclip 0s linear 2s forwards;
  animation: addclip 0s linear 2s forwards;
}
@keyframes addclip {
  to {
    clip-path: url(#art);
  }
}
@-webkit-keyframes addclip {
  to {
    clip-path: url(#art);
  }
}
#foreground {

  stroke-width: 10px;
  stroke-dasharray: 1028px;
  -webkit-animation: dash 2s;
  animation: dash 2s;
}
@keyframes dash {
  from {
    stroke-dashoffset: 1028px;
  }
  to {
    stroke-dashoffset: 0px;
  }
}
@-webkit-keyframes dash {
  from {
    stroke-dashoffset: 1028px;
  }
  to {
    stroke-dashoffset: 0px;
  }
}
