html - CSS 响应式设计重叠主体

情况是:我正在自学如何制作网站。我已经知道一些东西，现在我决定创建一个网站。但我有一些挣扎......我试图让它响应， Ant 它有点工作，但是当你调整页面大小时页脚与正文中的内容重叠......

想法是在标签开始重叠时向下滚动标签。

我用谷歌搜索了类似的问题并检查了线程，尝试了很多东西，但仍然一无所获:| 帮忙？...

最佳答案

要实现响应式网页设计，请使用 CSS3 媒体查询

重叠问题是由于 homecontainer 类的最小高度和标签类的固定位置

请使用 CSS3 媒体查询检查以下选项 https://codepen.io/nagasai/pen/vJbqeE

CSS:

html{
  height:100%;
}

body{
  height:100%;
  margin: 0px;
  font-family: 'Open Sans', sans-serif;

background-image: url(https://umad.com/img/2015/1/dark-geometric-wallpaper-176-205-hd-wallpapers.jpg);

}

/*+++NAVBAR*/
#primary_nav_wrap{
width: 100%;

  margin: 0;

}

#primary_nav_wrap ul

    list-style:none;
    position:relative;
    float:left;
    margin:0;
    padding:0;
}

#primary_nav_wrap ul a
{
    display:block;
    color:#fff;
    text-decoration:none;
    font-weight:500;
    line-height:50px;

    padding:0 20px;
    font-family: 'Open Sans',"Helvetica Neue",Helvetica,Arial,sans-serif
}

#primary_nav_wrap ul li

    position:relative;
    float:left;
    margin:0;
    padding:0
