什么是pointer-events？

在这里插入图片描述

pointer-events 属性是一个指针属性，是用于控制在什么条件下特定的图形元素可以成为指针事件的目标。

This CSS property,when set to “none” allows elements to not receive hover/click events,instead the event will occur on anything behind it.

当这个属性设置为none时，元素则不接收hover、click事件，由他后面的元素进行接收。

/* Keyword values */
pointer-events: auto;
pointer-events: none;
pointer-events: visiblePainted; /* SVG only */
pointer-events: visibleFill;    /* SVG only */
pointer-events: visibleStroke;  /* SVG only */
pointer-events: visible;        /* SVG only */
pointer-events: painted;        /* SVG only */
pointer-events: fill;           /* SVG only */
pointer-events: stroke;         /* SVG only */
pointer-events: all;            /* SVG only */

/* Global values */
pointer-events: inherit;  从其父元素继承此属性
pointer-events: initial;  将此属性设置为其默认值

除去SVG的独有属性，其他是对浏览器来说生效的属性值。
