当屏幕宽度小于768像素时，Boostrap dashboard example完全隐藏侧边栏导航（不折叠或堆叠）。您如何通过这样的设置支持移动设备？

Answer 1

Bootstrap 4

Create a responsive navbar sidebar "drawer" in Bootstrap 4?

Bootstrap 3

另一个选择是将仪表板和＆＃34; off-canvas＆＃34;侧边栏模板。这种布局允许侧栏在较小的宽度上切换/关闭屏幕......

@media screen and (max-width: 768px) {
  .row-offcanvas {
    position: relative;
    -webkit-transition: all 0.25s ease-out;
    -moz-transition: all 0.25s ease-out;
    transition: all 0.25s ease-out;
  }

  .row-offcanvas-left
  .sidebar-offcanvas {
    left: -33%;
  }

  .row-offcanvas-left.active {
    left: 33%;
  }

  .sidebar-offcanvas {
    position: absolute;
    top: 0;
    width: 33%;
    margin-left: 10px;
  }
}


/* Sidebar navigation */
.nav-sidebar {
  background-color: #f5f5f5;
  margin-right: -15px;
  margin-bottom: 20px;
  margin-left: -15px;
}
.nav-sidebar > li > a {
  padding-right: 20px;
  padding-left: 20px;
}
.nav-sidebar > .active > a {
  color: #fff;
  background-color: #428bca;
}

Answer 2

“大于”移动视图的侧边栏的CSS在以下位置指定：

@media (min-width: 768px)
   .sidebar {
      position: fixed;
      top: 51px;
      bottom: 0;
      left: 0;
      z-index: 1000;
      display: block;
      padding: 20px;
      overflow-x: hidden;
      overflow-y: auto;
      background-color: #f5f5f5;
      border-right: 1px solid #eee;
   }

之后它将恢复为默认值display:none

.sidebar {
   display: none;
}

您需要更改其默认CSS，或添加新的media query，例如

@media (max-width: 768px)

为了专门针对较小的设备。您希望应用的样式类型取决于您所追求的内容。
