这是一款基于HTML5 SVG和snap.svg的超酷天气预报卡片设计效果。该天气预报卡片可以以选项卡的方式来切换不同的天气，每种天气都以svg动画的方式来进行展示。

使用方法

在页面中引入jquery、TweenMax.min.js、snap.svg-min.js和main.js文件，以及样式文件style.css。

<link rel="stylesheet" href="css/style.css">
<script src="path/to/jquery.min.js" type="text/javascript"></script>
<script src='https://cdnjs.cloudflare.com/ajax/libs/gsap/1.19.0/TweenMax.min.js'></script>
<script src='https://cdnjs.cloudflare.com/ajax/libs/snap.svg/0.4.1/snap.svg-min.js'></script>
<script src="js/main.js"></script>
