.code-footer::after{
  content: '';
  width: 20rpx;
  height: 20rpx;
  border-radius: 10rpx;
  position: absolute;
  top:-10rpx;
  left:-10rpx;
  background-color: #EFEFF4;
}
.code-footer::before{
  content: '';
  width: 20rpx;

  border-radius: 10rpx;
  position: absolute;
  top:-10rpx;
  right:-10rpx;
  background-color: #EFEFF4;
}

  line-height: 48rpx;
  display: -webkit-box;
  -webkit-box-orient: vertical;
  -webkit-line-clamp: 2;
  overflow: hidden;
  height: 96rpx;

不换行加 ...

 white-space: nowrap;
 overflow: hidden;
 text-overflow: ellipsis;

一个 DIV或者其他元素的文本，如果都是无文字分隔符，无空格，则不会自动换行
  word-break: break-all; 

    var pages = getCurrentPages();
    var currpage = pages[pages.length - 1];
    var prePage = pages[pages.length - 2];

Array.splice(0,0,item);  第二个不为0删除，为0添加
