利用流布局，设置z-index层级，将image标签置于底层
//html <view class="container"> <image src='../image/1.jpg'></image> <view class='up'> 背景图片 </view> </view>
//css .container{ width: 100%; height: 600rpx; margin: 0; padding: 0; position: relative; } image{ position: absolute; width: 100%; height: 600rpx; } .up{ position: absolute; z-index: 1; }
