This phenomenon is no problem on Android phones, but the fixed part of the Apple phone will float when sliding.
<div style="height: 100%; overflow: auto;">I am the content</div> <div style="position: fixed">我是fixed</div>
As the code shows,
The content part gives a height: 100%; overflow: auto;
The fixed part can be added according to your needs
If there is still a problem, put the part that needs to be fixed to the outermost, that is, the subordinate of the body can solve the problem
