菜单打开时如何更改 Font Awesome 图标的颜色？

Question

我通过选中的输入制作了一个“汉堡菜单”。

我想知道当菜单展开时，目标是什么以及使用什么伪元素来更改字体超棒的颜色或背景？我是否可以通过单击页面中的任意位置来关闭此菜单？

Answer 1

试试这个 .elem{background-color: red;padding:3px;text-align:center;color:green;}

更改图标颜色使用 color:<color-name>; 因为是基于字体

Answer 2

要更改超棒的字体颜色或背景，试试这个

CSS

.fas:hover {
  background-color: #000;
   color: #fff;
}

JS

var ico = document.getElementsByClassName("fa-ico")[0]
ico.addEventListener('click', function () {
   this.style.color = "red"
})

关于关闭菜单你可以使用e.target

Example

var container = document.getElementsByClassName("container")[0]
container.addEventListener('click', function (e) {
   if(e.target.className === "container") {
      this.style.display = "none";
   }
})
