Bootstrap 4 弹出框箭头轮廓

Question

我找到了 100 个不同的答案，但 none 似乎有效。我试图摆脱 Bootstrap 4 弹出框箭头上的轮廓。我已经尝试了我能想到的每一个伪目标。我正在使用底部弹出窗口。非常感谢任何帮助。

你能试试下面的方法吗？至少它正在他们的网站上工作。

.popover .arrow::before {
   border-bottom-color: white; /* might need to add !important */
}

$(function () {
  $('[data-toggle="popover"]').popover()
})

.popover .arrow::before {
   border-bottom-color: white !important;
}

这应该有效：

.popover .arrow:before {
    border-color: transparent;
}

或者如果您使用 bootstrap 变量：

$popover-arrow-outer-color: transparent;
