Question

我正在开发一个简单的聊天应用程序，我想要一个侧边栏，用户可以选择房间。侧边栏必须是可折叠的，但是我知道我的侧边栏是固定的，并且与聊天对话应该显示的面板元素重叠。

.panel-body {
  height: 75vh;
  width: 75%;
  float: rigth;
}
body {
  overflow-x: hidden;
}
/* Toggle Styles */

#wrapper {
  padding-left: 0;
  -webkit-transition: all 0.5s ease;
  -moz-transition: all 0.5s ease;
  -o-transition: all 0.5s ease;
  transition: all 0.5s ease;
}
#wrapper.toggled {
  padding-left: 250px;
}
#sidebar-wrapper {
  z-index: 1000;
  position: absolute;
  float: left;
  left: 250px;
  width: 0;
  height: 100%;
  margin-left: -250px;
  overflow-y: auto;
  background: #000;
  -webkit-transition: all 0.5s ease;
  -moz-transition: all 0.5s ease;
  -o-transition: all 0.5s ease;
  transition: all 0.5s ease;
}
#wrapper.toggled #sidebar-wrapper {
  width: 250px;
}
#page-content-wrapper {
  width: 100%;
  position: absolute;
  padding: 15px;
}
#wrapper.toggled #page-content-wrapper {
  position: absolute;
  margin-right: -250px;
}
/* Sidebar Styles */

.sidebar-nav {
  position: absolute;
  top: 0;
  width: 250px;
  margin: 0;
  padding: 0;
  list-style: none;
}
.sidebar-nav li {
  text-indent: 20px;
  line-height: 40px;
}
.sidebar-nav li a {
  display: block;
  text-decoration: none;
  color: #999999;
}
.sidebar-nav li a:hover {
  text-decoration: none;
  color: #fff;
  background: rgba(255, 255, 255, 0.2);
}
.sidebar-nav li a:active,
.sidebar-nav li a:focus {
  text-decoration: none;
}
.sidebar-nav > .sidebar-brand {

  background: none;
}
@media(min-width:768px) {
  #wrapper {
    padding-left: 250px;
  }
  #wrapper.toggled {
    padding-left: 0;
  }
  #sidebar-wrapper {
    width: 250px;
  }
  #wrapper.toggled #sidebar-wrapper {
    width: 0;
  }
  #page-content-wrapper {
    padding: 20px;
    position: relative;
  }
  #wrapper.toggled #page-content-wrapper {
    position: relative;
    margin-right: 0;
  }
}

如何修复此问题，以便面板元素在侧边栏折叠时调整宽度？

谢谢，我将非常感谢您的帮助。

这可以为您工作（如果没有，则回复此答案）引导程序具有相同的类，使用1024px而不是bootstrap的本机：

    /* 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;
    }
}
