关键技术：
1、对每一行（标签和输入框组件）限制长度 max-width:360px;
2、对【性别】进行左边浮动，它的文本进行右对齐。
光标样式
cursor 属性有不同的值，这些值让光标显示不同的形状。
常见的形状有：
| 属性值 | 说明 |
| default | 默认光标，通常是一个箭头 |
| auto | 浏览器自动识别的光标 |
| crosshair | 十字线 |
| pointer | 手型指针 |
| move | 移动指针 |
| text | 文本指针 |
| wait | 指示程序正忙 |
| col-resize | 双向移动 |
| help | 帮助指针 |
