前言：为什么分享出来？是因为本案例有很多亮点，作为经验的分享和自我总结，着急看亮点的，请直接看本章最后的总结

先看样式吧：

接着看代码：

HTML:

//微信小程序
<view class="page">
    <view class="wrapper" wx:for="{{list}}" key='item.id'>
        <!-- 左侧box -->
        <view class="content">
            <view class="couponCount">{{item.size}}张</view>
            <view class="oilline linwidth160 lineBt"></view>
            <view>
                <text class="moyfh">¥</text>
                <text  class="moneyNum">{{item.price}}</text>
            </view>
            <view class="oilline  linwidth160 lineBt"></view>
        </view>

        <view class="split-line"></view>
        <!-- 右侧box -->
        <view class="tip">
            <view class="oilline linwidth227 lineBt "></view>
            <view class="vnameBx">

                <view class="couponmaes">满{{ item.activityPrice}}减{{item.price}}元</view>
            </view>
            <view class="oilline linwidth227 lineBt"></view>
            <view class="btnbx  {{item.isJoin==200?'':'moveCm'  }}">

            <view class="btnn" bindtap="submitCilck">{{btnTxt}}</view> 
                </view>
            </view>

总结：

1.本示例中的特色是，纯css写的优惠券齿轮，和中间的虚线；
2.样式类.oilline 用css实现了,中间粗且高亮两端细的渐变线条；
3.css实现容器右上角旋转45度的圆角角标，再也不用ui切图了；
4.补充：由左向右，左边粗，向右渐变变细的线条：

.oilline {
  background: -webkit-linear-gradient(right, rgba(251, 251, 251, 0.09), rgba(251, 251, 251, 0.59), #FFF);
  /* Safari 5.1 - 6.0 */
  background: -o-linear-gradient(left, rgba(251, 251, 251, 0.09), rgba(251, 251, 251, 0.59), #FFF);
  /* Opera 11.1 - 12.0 */
  background: -moz-linear-gradient(left, rgba(251, 251, 251, 0.09), rgba(251, 251, 251, 0.59), #FFF);
  /* Firefox 3.6 - 15 */
  background: linear-gradient(to left, rgba(251, 251, 251, 0.09)rgba(251, 251, 251, 0.59), , #FFF);
  /* 标准的语法（必须放在最后） */
  height: 2rpx;
  width: 285rpx;
}
.lineBt {
  margin-bottom: 20rpx;
