因为一个视觉例子比言语更响亮......

以下是创建垂直导航栏的一种方法。请注意，媒体查询需要根据导航栏标记navbar-expand-<size>中使用的<nav class="navbar navbar-expand-sm ...类进行调整

@media only screen and (min-width: 576px) {
  .vertiNav {
    width: 100px;
  }
  .vertiNav nav.navbar {
    flex-direction: column !important;
  }
}

@media only screen and (max-width: 576px) {
  .vertiNav {
    width: 100%;
  }
  .vertiNav nav.navbar {
    flex-direction: row !important;
  }
}
