Question

我有这个SVG，我希望从左到右顺利填充。我怎么能用CSS做到这一点？

我不希望线条移动，我希望它在从同一个地方停留时从左到右顺利填充，这就是我使用svg的原因。

<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="324" height="25" viewBox="0 0 324 25">

Answer 1

你可以这样做。

svg {
  left: -400px;
  position:absolute;
}

@keyframes example {
    from {left: -400px;}
    to {left: 200px;}
}

@-webkit-keyframes example {
    from {left: -400px;}
    to {left: 200px;}
}

svg {
    animation-name: example;
    animation-duration: 4s;
    animation-delay: 2s;
    animation-iteration-count: infinite;
    animation-timing-function: ease-in-out;
}

Answer 2

试试这个

.fadeIn {
  animation-name: fade-in-left;
  animation-duration: 1s;
}

@keyframes fade-in-left {
  0% {
    opacity: 0;
    transform: translate3d(-100%, 0, 0);
  }

  100% {
    opacity: 1;
    transform: none;
  }
}

Answer 3

你可以在CSS中使用stroke属性执行此操作。

我很抱歉提前，我不能使用你的SVG，因为它是一个形状，为了使你的效果，你只需要一个没有填充的路径。所以我把这个SVG作为例子（来自这篇文章：https://jakearchibald.com/2013/animated-line-drawing-svg/）：

<svg xmlns="http://www.w3.org/2000/svg" height="98" width="581" viewBox="0 0 581 98">
   <path 
      class="path" 
      d="M62.9 14.9c-25-7.74-56.6 4.8-60.4 24.3-3.73 19.6 21.6 35 39.6 37.6 42.8 6.2 72.9-53.4 116-58.9 65-18.2 191 101 215 28.8 5-16.7-7-49.1-34-44-34 11.5-31 46.5-14 69.3 9.38 12.6 24.2 20.6 39.8 22.9 91.4 9.05 102-98.9 176-86.7 18.8 3.81 33 17.3 36.7 34.6 2.01 10.2.124 21.1-5.18 30.1" 
      stroke="#000" 
      stroke-width="4.3" 
      fill="none">
   </path>
</svg>

请注意stroke和stroke-width属性。这是技巧的开始;）。然后你需要添加一些CSS：

.path {
   //we divide the line in multiple dashes (some full and other empty)
   //these dashes have 1000px in length
   //so there are one dash full of 1000px of length and then one dash empty of 1000px of length and so on and so forth
   stroke-dasharray: 1000;

   //we change the position of the dashes
   stroke-dashoffset: 1000;

   //now we animate the dashoffset
   //we reduce the offset of each dash so we have the impression that the dashes are moving
   animation: dash 5s linear forwards;
}

@keyframes dash {
   to {
      stroke-dashoffset: 0;
   }
}

就是这样！
