Question

我下面有一个codepen。基本上，我试图在突出显示的圆圈（红色）上显示一个弹出窗口，但是有些突出显示的圆圈显示在某些弹出窗口之上，即使弹出窗口总是始终被赋予更高的z-index。 / p>

这是用于弹出窗口的动画，我认为这可能是罪魁祸首。

@-webkit-keyframes popup {
 0% {
    transform: scale(2.5);
  }
  100% {
    transform: scale(0);
  }
}

Answer 1

取出.white-popup上的z-index设置，并在.white-popup上设置更高的z-index：hover .popup和.white：hover。见jsfiddle

Answer 2

我添加了以下CSS：

td:hover {
    z-index: 1;
}

在.white-popup选择器内，我删除了：

z-index: 2;

线。

似乎适合我。
