页面的head部分，仅需引入一个CSS样式文件即可，代码如下：

<link type="text/css" rel="stylesheet" href="css/style.css">

页面的body部分，将所有元素放置于一个div容器里，这里注意一下用于创建多边形的SVG字标签polygon,代码如下：

<div class="container"> 
  <svg viewBox="0 0 3387 1270">
    <path id="planePath" class="planePath" d="M-226 626c439,4 636,-213 934,-225 755,-31 602,769 1334,658 562,-86 668,-698 266,-908 -401,-210 -893,189 -632,630 260,441 747,121 1051,91 360,-36 889,179 889,179"/>
  <g  id="plane">
   <polygon class="fil1" points="-141,-10 199,0 -198,-72 -188,-61 -171,-57 -184,-57 "/>
   <polygon class="fil2" points="199,0 -141,-10 -163,63 -123,9 "/>
   <polygon class="fil3" points="-95,39 -113,32 -123,9 -163,63 -105,53 -108,45 -87,48 -90,45 -103,41 -94,41 "/>
