与Bootstrap和Django结合使用的响应式设计不起作用

如何解决与Bootstrap和Django结合使用的响应式设计不起作用

我不知道在哪里出错。我的代码中有什么不正确？我有带有以下子页面的网站。响应式设计不起作用。它与HTML / CSS代码中的任何错误有关，还是与媒体查询有关，我应该在引导程序中使用任何特定的方式进行自适应设计？通常，行和列存在问题-我无法及时更改边距和字体大小。可能与Django继承机制有关吗？

解决方法

您可以在媒体查询的每一行末尾添加！important。例如：

<style>
  @include media-breakpoint-up(sm)
    
    .row{
    font-size:10px !important;
    margin:10px !important;
    
    }
    }
</style>
