注意点：
1.在开始时先用一个大的view把整个页面包裹起来
2.每个view下的子view要缩进，方便区分
3.一定要用英文定义类，不记得的单词要查！！！
a.在做弹性布局的时候要现在全局的view里边wxss定义一个 display:flex;
b.wxss颜色：
css中border旋转：
轮播图代码：
//.wxml
<swiper indicator-dots="{{indicatorDots}}" autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}"
class="swiper">
<block wx:for="{{imgUrls}}">
<swiper-item>
<image src="{{item}}" class="slide-image" />
</swiper-item>
</block>
</swiper>
//.wxss
