css - Bootstrap 4 游标，用于处于禁用状态的自定义控件

Question

我需要其他光标来禁用自定义控件元素(复选框、单选按钮)

这种风格不起作用:

.custom-control-input:disabled ~ .custom-control-label::before {
    cursor: not-allowed;
}

Answer 1

对于 Bootstrap 4 中禁用的自定义控件元素(复选框、单选按钮)，您需要以下选择器 css 规则/选择器:

.custom-control-input:disabled ~ .custom-control-label {
    cursor: not-allowed;
}

如果您只想为实际的复选框/单选按钮而不是标签使用自定义光标样式(在这种情况下不推荐)，那么您需要这条规则:

.custom-control-input:disabled ~ .custom-control-label::after {
    cursor: not-allowed;
}
