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。

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。
for
id
如今,您可以使用BS4代替BS3。
