我正在开发一个简单的聊天应用程序，并且需要一个边栏，用户可以在其中选择房间。侧边栏必须是可折叠的，但我知道侧边栏是固定的，并且与聊天对话应显示的面板元素重叠。
.panel-body {
height: 75vh;
width: 75%;
float: rigth;
}

overflow-x: hidden;
}

谢谢，我将感谢您的帮助。
最佳答案
这可以为您工作（如果没有，请回答此答案）。bootstrap具有相同的类，它们从1024px开始而不是bootstrap的本机工作：
/* Modify max-with to change breakpoint */
@media (max-width: 1024px) {
.navbar-header {
float: none;
}
.navbar-left,.navbar-right {
float: none !important;
}
.navbar-toggle {
display: block;
}
.navbar-collapse {
border-top: 1px solid transparent;
box-shadow: inset 0 1px 0 rgba(255,255,255,0.1);
}
.navbar-fixed-top {
top: 0;
border-width: 0 0 1px;
}
.navbar-collapse.collapse {
display: none!important;
}
.navbar-nav {
float: none!important;
margin-top: 7.5px;
}
.navbar-nav>li {
float: none;
}
.navbar-nav>li>a {
padding-top: 10px;
padding-bottom: 10px;
}
.collapse.in{
display:block !important;
}
.navbar-nav .open .dropdown-menu {
position: static;
float: none;
width: auto;
margin-top: 0;
background-color: transparent;
border: 0;
-webkit-box-shadow: none;
box-shadow: none;
}
}
