Layui表单必填项自动打红色*号

<span style="color:red">*</span>

<style>
  .layui-input{height:30px;} /* layui-input 默认太高了，这里固定高度*/
  label.required:after {   /* 给红色的必填项打红色星号（文字后）如果打前面用before*/
        content: ' *';
        color: red;
    }
</style>
  .layui-form-label.required:after {   /* 这种写法也可以*/
        content: ' *';
        color: red;
    }
