When a page with a more complex layout is run on a mobile browser, some phones with poor configurations will appear after scrolling the scroll bar. The page will scroll normally, but some elements will appear similar to position: fixed. Generally hover on the page and then scroll. It looks a bit like parallax scrolling, but not pretty at all.
Solution: Add style to the sliding body: transform: translateZ(0); -webkite-transform: translateZ(0).
<div style="height:300px;overflow:auto"> <div style="transform:translateZ(0);-webkite-transform:translateZ(0);"> 各种复杂的html <div></div>
The purpose of adding this is to take advantage of GPU acceleration (GPU cache).
Because of this problem, it was also discovered that if you use overflow:auto to slide the page (html scroll bar form), the browser will frequently scroll, update layer tree, and composite layers every time the page slides. There should be a problem in the last link. The reason for this problem should be the layout method.
