微信小程序

最近看到南湖微科普小程序游戏环节感觉还可以，于是模仿了下

<view class='current' animation="{{animation}}">
  {{current.title}}
</view>
<view class='caozuo'>
  <text bindtap="type1btn">可回收</text>
  <text bindtap="type2btn">有害垃圾</text>
  <text bindtap="type3btn">其他</text>
</view>
<view class='score'>分数：{{score}}</view>

　　

.current{ 100px;height:100px;border-radius:5px; margin:20px auto;text-align:center;line-height:100px;color:#fff;background:red; }
.caozuo{display: flex;justify-content:space-between;margin-top: 15px;font-size:14px;text-align: center;}
.caozuo text{text-align: center;flex:1;}
.score{ text-align:center;margin-top:20px;font-size:14px;color:red; }
