页面的head部分，需设置好页面元素的样式，代码如下：

html, body {
  height: 100%;
}

body {
  background: #082330;
  background-size: .12em 100%;
  font: 12em/1 'Microsoft YaHei','Lantinghei SC','Open Sans',Arial,'Hiragino Sans GB','STHeiti','WenQuanYi Micro Hei','SimSun',sans-serif;
}

.text--line {
  font-size: .5em;
}

svg {
  position: absolute;
  width: 100%;
  height: 100%;
}

.text-copy {
  fill: none;
  stroke: white;
  stroke-dasharray: 8% 18%;
  stroke-width: 2px;
  -webkit-animation: stroke-offset 9s infinite linear;
          animation: stroke-offset 9s infinite linear;
}
.text-copy:nth-child(1) {
  stroke: #360745;
  stroke-dashoffset: 7%;
}
.text-copy:nth-child(2) {
  stroke: #D61C59;
  stroke-dashoffset: 14%;
}
.text-copy:nth-child(3) {
  stroke: #E7D84B;
  stroke-dashoffset: 21%;
}
.text-copy:nth-child(4) {
  stroke: #EFEAC5;
  stroke-dashoffset: 28%;
}
.text-copy:nth-child(5) {
  stroke: #1B8798;
  stroke-dashoffset: 35%;
}

@-webkit-keyframes stroke-offset {
  50% {
    stroke-dashoffset: 35%;
    stroke-dasharray: 0 87.5%;
  }
}

@keyframes stroke-offset {
  50% {
    stroke-dashoffset: 35%;
    stroke-dasharray: 0 87.5%;
  }
}

页面的body部分，主要是svg设置好容器大小和文字的位置等，代码如下：

<svg viewBox="0 0 1024 768">
  <symbol id="s-text">
    <text text-anchor="middle"
          x="50%"
          y="35%"
          class="text--line"
          >
      jy.tp.yuanmeng.life
    </text>
    <text text-anchor="middle"
          x="50%"
          y="68%"
          class="text--line2"
          >
      智慧小屋
    </text>
  </symbol>
  <g class="g-ants">
    <use xlink:href="#s-text"
      class="text-copy"></use>     
    <use xlink:href="#s-text"
      class="text-copy"></use>     
    <use xlink:href="#s-text"
      class="text-copy"></use>     
    <use xlink:href="#s-text"
      class="text-copy"></use>     
    <use xlink:href="#s-text"
      class="text-copy"></use>     
  </g>
</svg>
