如何使用纯CSS切换侧边栏菜单？

编程问答 2022-06-11

问题描述

我有BS4侧边栏菜单，应在单击时切换并替换图标。这是代码：

.toggle {
  display: none;
}
.menu-head label {
  color: black;
  cursor: pointer;
}
.container {
    overflow: hidden;
    display: inline-block;
}
.side-bar {
    background:#3e4140;
    position: absolute;
    height: 100%;
    width: 200px;
    color:#fff;
    transition: margin-left 0.5s;
}
.side-bar ul {
    list-style: none;
    padding: 0px;
}
.side-bar ul li.menu-head {
    padding: 20px;
    background-color: #ECECEA;
}
.side-bar ul .menu li a {
    color:#fff;
    text-decoration: none;
    display: inline-table;
    width: 100%;
    padding-left: 20px;
    padding-right: 20px;
    padding-top: 10px;
    padding-bottom: 10px;
}
.side-bar ul .menu li a:hover {
    border-left:3px solid #ECECEA;    
    padding-left:17px;
}
.content {
    padding-left: 200px;
    transition: padding-left 0.5s;
}

我用真棒字体图标创建了按钮，该按钮应关闭菜单。菜单关闭后，理想的情况是仍然在侧面显示图标。关闭（X）图标按钮应更改为菜单图标（三条水平线）。在超赞的4.7版中，该图标的代码在此处：<i class="fa fa-bars" aria-hidden="true"></i>。切换功能应使用纯CSS。我已经知道可以使用jQuery完成此操作，但这不是我正在寻找的解决方案。谢谢。

解决方法

这是一个带有input checkbox的CSS实例，它模仿了代码中的切换效果，其中我将button变成了链接到{{1 }}通过label和input。从那里开始，您将需要调整一些类或一些CSS规则，使其表现良好。

id

如今，您可以使用BS4代替BS3。

这是我用于我的一个项目的以下代码。找到下面的演示
