Php Wordpress光标位于站点后面

我最近为wordpress安装了鼠标/光标试用插件。该插件正在工作，但是鼠标轨迹图像在网站内容后面消失，只显示在背景上

请问有谁能指引我正确的方向修理它

多谢各位

如果有相同的问题，这就解决了：

img[src$="/pointer.png"],
img[src$="/valentines.png"] {
  z-index: 1000!important;
}

---

img的z索引仅限于父元素。检查此元素是否位于其他内容后面。如果是这样的话，z指数1000将没有任何帮助。必须将父元素放置在其他元素的前面

img[src$="/pointer.png"],
img[src$="/valentines.png"] {
  z-index: 1000!important;
}
