如何将移动端汉堡菜单图标移至页眉右侧？

别担心，这个调整其实很简单，只需要修改几处CSS属性就能搞定！下面是修改后的完整代码，我标注了关键的改动点：

.wrapper {
  width: 480px;

  margin: 0 auto;
  overflow: hidden;

}

body {
  background-color: #f1f1f1;
  padding: 0;
  margin: 0;

}

关键改动说明： #

• 导航栏布局：给nav添加justify-content: flex-end（加上前缀兼容旧浏览器），让汉堡菜单图标直接靠右显示。
• 主菜单位置：把nav .m-menu的left: 0改成right: 0，同时将初始的transform: translate3d(-450px, 0, 0)改为translate3d(450px, 0, 0)，这样菜单默认隐藏在屏幕右侧外面，点击后平滑滑入。
• 子菜单滑动方向：修改nav .m-menu .m-menu的transform为translate3d(-480px, 0, 0)，让子菜单向左滑入，符合右侧菜单的交互逻辑。

HTML部分不需要做任何修改，直接用你原来的代码就可以正常运行啦~
