1.給圖片包裹元素加屬性
position: relative;                                                                        //用彈性盒子讓圖片垂直排列
display: flex;
flex-direction: column;

2.給圖片本身加屬性
1）vertical-align:top;  或者  vertical-align:bottom;                         //垂直對齊方式

2）margin-top: -10rpx;     (先不建議這種方法哈，不夠科學)               //負margin值
