Absolute positioning of WeChat mini program pictures

Foreword:

In small programs, sometimes you need to use background images, but if you use background-image, you cannot control the size of the image. Background-image is generally used for Compress the image into a 1-pixel background image, and then automatically fill it. If you use a background image, you generally use some new view layers, such as 7c13d7ef66bafa0a636fe9de418b497e, etc., but the size is small The program is similar to HTML. A different css or wxss will occupy a position, and then the next css or wxss will automatically typeset downwards. However, many times this is not what we want, so absolute positioning needs to be used.

To use absolute positioning, it is best to use a new wxss to include all child controls, and then in this wxss containing all child controls, define a property position: relative, in each child control , define position: absolute, now you can modify the position through absolute positioning, such as top, etc. Attached below is part of the wxss code:

.jx_card{
  width: 100%;
  height: 295rpx;
  background-color:#e6e6e6;
  position: relative
}
 .jxlogo{
  top: 47.5rpx;
  margin-left: 50rpx;
  width: 200rpx;
  height: 200rpx;
  float: left;
  position: absolute;
}

Then attach wxml Code:

<view class="jx_card">
  <image style="width: 740rpx; height: 275rpx;margin-left=10rpx;margin-top:10rpx;" mode="{{item.mode}}" src="../../image/优惠券_03.png">
      <image class="jxlogo" src="../../image/jx.png"/>
  </image>
 </view>

The content is roughly like this. It mainly defines the positioning type through position, and then uses top to find the position on the picture and define it.
