一、按钮

1、写法

<button type="button" class="layui-btn">一个标准的按钮</button>
<a href="http://www.layui.com" class="layui-btn">一个可跳转的按钮</a>

2、颜色

<button type="button" class="layui-btn layui-btn-primary">原始</button>
<button type="button" class="layui-btn">默认</button>
<button type="button" class="layui-btn layui-btn-normal">百搭</button>

<button type="button" class="layui-btn layui-btn-danger">警告</button>
<button type="button" class="layui-btn layui-btn-disabled">禁用</button>

3、镂空

  <button type="button" class="layui-btn">增加</button>
  <button type="button" class="layui-btn">编辑</button>
  <button type="button" class="layui-btn">删除</button>
</div>

二、表单

• 在一个容器中设定 class="layui-form" 来标识一个表单元素块，通过规范好的 HTML 结构及 CSS 类，来组装成各式各样的表单元素，并通过内置的 form 模块 来完成各种交互。
• 依赖加载模块：form （如果不加载 form 模块，select、checkbox、radio 等将无法显示，并且无法使用 form 相关功能）

1、输入框

<form class="layui-form">
  <input type="text" placeholder="请输入标题" class="layui-input" />
</form>

2、下拉选择框

默认选中

<form class="layui-form">
  <select>
    <option value="">请选择一个老师</option>
    <option value="1">天蓬</option>
    <option value="2">灭绝师太</option>
    <option value="3">西门大官人</option>
    <option value="4">欧阳克</option>
  </select>
  <select>
    <option value=""></option>
    <option value="1">天蓬</option>
    <option value="2">灭绝师太</option>
    <option value="3">西门大官人</option>
    <option value="4">欧阳克</option>
  </select>
  <select>
    <option value="1">天蓬</option>
    <option value="2">灭绝师太</option>
    <option value="3">西门大官人</option>
    <option value="4">欧阳克</option>
  </select>
</form>

自定义：选中、禁用

  <select>
    <option value="1">天蓬</option>
    <option value="2" selected>灭绝师太</option>
    <option value="3">西门大官人</option>
    <option value="4" disabled>欧阳克</option>
  </select>
</form>

分组

<form class="layui-form">
  <select>
    <option value="">请选择</option>
    <optgroup label="男老师">
      <option value="1">天蓬</option>
      <option value="3">西门大官人</option>
      <option value="4">欧阳克</option>
