Bootstrap 4 自定义控件光标处于禁用状态

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 custom-control 元素（复选框、单选按钮），您需要以下选择器 css rule/selector:

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

而且，如果您只想为实际的 checkbox/radio 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;
}

单击下面的 "run code snippet" 以查看它是否有效：

    <div class="custom-control custom-radio custom-control-inline">
