首先，媒体查询规则应该在CSS中排在最后，否则它们不会覆盖主规则中设置的任何设置。

其次，你的元素上有内联样式，例如包含地图的div具有150px的固定高度，这很可能会破坏你的外部规则。

我建议用类替换内联样式，以获得更易维护且更不容易出错的代码。

根据评论进行更新

而不是像这样在标记中使用内联样式，

<div style="width:300px;max-width:100%;overflow:hidden;height:150px;color:red;">

用类

替换内联样式

<div class="div-for-map">

并将其添加到您的CSS中。

.div-for-map {
  width:300px;
  max-width:100%;
  overflow:hidden;
  height:150px;
  color:red;
}

媒体查询中页脚的高度
