DEMO
我看文档上是这样写的:
A percentage for the horizontal offset is relative to (width of background positioning area - width of background image). A percentage for the vertical offset is relative to (height of background positioning area - height of background image), where the size of the image is the size given by ‘background-size’.
那么为什么10%就会偏移那么多呢？
不解。

I didn’t see the effect of your code. I’m not sure what to say. Please give me a link first
The coordinates of bgp are only positioned with negative values~
10% will offset that much. It depends on the size of your box (picture). This is relative.
The key depends on how you position it. It is recommended to take out the source code and take a look
This attribute sets the position of the background-image, and it also depends on how you position the box and the size of the image
Look at the calculation method of percentage, which is to align the position corresponding to 10% of the picture with the position corresponding to 10% of the background positioning.
