css - Bootstrap 4 工具提示箭头阴影样式

Question

这是没有阴影的工具提示箭头:

我正试图对其进行阴影处理，但由于箭头是由边框组成的，因此我无法呈现正确的结果。获取以下内容:

有什么想法可以将箭头部分的阴影集成到工具提示的其余部分吗？(下面的代码段)

检查了 following和其他一些人，但找不到影子特定场景。

谢谢。

$('[data-toggle="tooltip"]').tooltip('show');

html body {
  background: #eee;
}

button.btn {
  margin-top: 100px;
}

.tooltip-inner {
  background-color: white !important;
  color: gray !important;
  border-radius: 0 !important;
  box-shadow: 2px 2px 4px 0px rgba(161, 161, 161, 1);
}

.bs-tooltip-right .arrow::before {
  border-right-color: white !important;
  box-shadow: 2px 2px 4px 0px rgba(161, 161, 161, 1);
}

您可以通过一点 css 魔术并将样式应用于 ::after 伪元素来实现这一点。在那里添加阴影并将 z-index 降低到 -1 以坐在后面并提供所需的效果。

$('[data-toggle="tooltip"]').tooltip('show');

html body {
  background: #eee;
  margin: 30px;
}

.tooltip-inner {
  background-color: white !important;
  color: gray !important;
  border-radius: 0 !important;
  box-shadow: 2px 2px 4px 0px rgba(161, 161, 161, 1);
}

.bs-tooltip-right .arrow::before {
  border-right-color: white !important;
}

.bs-tooltip-right .arrow::after {
  content: "";
  position: absolute;
  left: 100%;
  z-index: -1;
  border: 5px solid #fff;
  transform-origin: 0 0;
  transform: rotate(45deg);
  box-shadow: 2px 2px 4px 0px rgba(161, 161, 161, 1);
}
