CSS--实现<圆形导航菜单>

概要

层叠样式表(英文全称：Cascading Style Sheets)是一种用来表现HTML（标准通用标记语言的一个应用）或XML（标准通用标记语言的一个子集）等文件样式的计算机语言。CSS不仅可以静态地修饰网页，还可以配合各种脚本语言动态地对网页各元素进行格式化。熟练掌握CSS的基本原理可以实现更好的页面交互效果，提升用户的使用体验。

代码实现

新建文件夹circle-nav，circle-nav下新建index.html和style.css文件，index.html引入本地font-awesome字体库或者CDN上的资源

目录结构

/**
circle-nav
   ├─ fontawesome-free-5.11.2-web
   ├─ index.html
   └─ style.css
*/
