Answer 1

nav{
       text-align:right;
      position:relative;

  }
  nav ul li {
    border: 1px solid;
     display: inline-block;
     margin-left: 5px;
     margin-right: -4px;
     position: relative;
      z-index: 1000;
     }

Answer 2

将float right属性提供给css中的nav：

nav {  
    margin: 20px auto;
    float: right;
}

Answer 3

尝试将float:right添加到您的nav css规则或nav ul css规则中，只需在控制台中执行此操作即可。

Answer 4

这将使news div保持在下面，并且会向右浮动

nav {
    float: right;
    margin: 20px auto;
    width: 100%;
}
nav ul {
    float: right;
}

<强> 结果 result

为什么我的水平菜单没有浮动到右边？
