node with the highest position on the z axis is the target DOM node to find. dom Tree records the Z-index value of each DOM node. Theoretically, with these z-index values, it is possible to determine the target DOM node of an input event, that is, the DOM tree can be used to determine . But from the previous Chromium page graphics Layer tree creation process analysis, a DOM node z-index value It does not ultimately determine its position on the z axis, but also relates to the Z-index value
