介绍
由国人开发，16年出厂的框架，其主要提供了很多好看、方便的样式，并且基本拿来即用，和Bootstrap有些相似，但个人认为该框架有个极大的好处就是定义了很多前后端交互的样式接口，如分页表格，只需在前端配置好接口，后端则按照定义好的接口规则返回数据，即可完成页面的展示，极大减少了后端人员的开发成本。
说白了，该框架就是为了方便后端人员开发前端而使用的。

Layui、Easyui和Bootstrap对比

个人总结（三个框架依次顺序）：美且轻、强但丑、简且稳
环境导入
// 本地导入：
// 导入CSS文件
// 导入JS文件
// CDN导入：
注：
若将Layui下载到本地进行导入时，记得在将layui.css和layui.js导入的同时，将其中的字体等也一同导入，以免显示的结果有异常
使用CDN导入时，提供的CDN链接由于配置文件，在导入字体文件等时会出现跨域请求的问题，所以字体等可能无法正常显示，因此不推荐，不过这里还是附上CDN链接：CDN链接

好用的内置模块
layer弹层
这个是该框架的代表作，常用于一些公告、提示框、轮播相册等场景，举例：

Layui踩坑记录
使用弹层时第一次的效果不对，之后又没问题
原因：第一次执行时资源没有加载完毕
解决办法：把弹层功能放在layer.ready中执行，举例：
layui.use('layer', function () {
let layer = layui.layer;
layer.ready(function () {
// 将内容放在ready方法里
layer.msg("测试", {
time: 0,
area: ['300px', '150px'],
shade: [0.6, '#000', true],
icon: 7,
shadeClose: true,
btn: ['关闭']
});
})
});
