Question

我用谷歌搜索并发现如何在这里响应Bootstrap 3 tab to accordion使用Bootstrap 3选项卡,但是我使用的是Bootstrap 4,我不知道如何将它转换为Bootstrap 4 tab到手风琴.请帮我.

谢谢!

Answer 1

如评论中所示,原始答案是针对Bootsrap 4 Beta 2编写的.发布的Bootstrap 4版本需要在标记/ css中进行两处更改.因此更新.

在Bootstrap 4中,您可以使用以下标记实现该功能.
(由于内置的​​代码片段查看器在css @media查询涉及的时候混合了一些东西,我也创建了一个Codepen.)

与BS 4 Beta 2相比,有两个必要的变化:

• 首先,隐藏了选项卡的隐藏方式:早期.tab-pane的不透明度由.fade类管理,但在发布的版本中,它是.fade:not(.show)选择器,具有更高的优先级.因此,要覆盖在css中需要更改的不透明度 ..tab-pane.tab-content > .tab-pane
• 其次,可折叠组的处理也发生了变化.以前是需要data-parent属性的切换按钮.但是,由于发布版本data-parent需要进入可折叠元素.

Bootstrap 4.1.3的更新代码如下:

HTML

        </li>
        <li class="nav-item">

@media(max-width:767px){
    /* 
     * Changed selector to `.tab-content > .tab-pane` in order to override `.fade:not(.show)`
     * In BS4 Beta `.tab-pane`s were rendered hidden by just `.fade`

    .tab-content > .tab-pane {
        display: block;
