我正在使用 this left sidebar . 我还在右边添加了一个div,左边填充边栏的大小。

现在,如果我切换到一个较小的屏幕,侧边栏将显示在顶部(这是一个理想的结果),但我的div保留了填充,内容位于屏幕右侧。

有可能吗?

只需覆盖 padding-left 所有物自从 #content 是导航栏的直接兄弟( .nav-side-menu adjacent sibling combinator ( + )并在目标屏幕上应用样式。

@media (max-width: 767px) {
  .nav-side-menu {
    position: relative;
    width: 100%;
    margin-bottom: 10px;
  }

  .nav-side-menu + #content {
    padding-left: 0;
  }

  /* the rest of the styles*/
}

从代码的外观来看,您似乎正在使用Bootstrap版本3,它有一个内置功能,可以根据屏幕大小显示或隐藏项目,这可能会对您有所帮助。 You can read more about that here .

或者,当屏幕宽度达到特定大小时,您也可以添加自己的媒体查询以删除填充。也许是这样的:

/* Extra Small Devices, Phones */ 
@media only screen and (min-width : 480px) {
  #content {
    padding-left: 0;
  }
}

如果您想了解更多关于BS断点的信息 you can look through this post here . 希望有帮助。
