要实现这样的功能很简单,它的原理是将图片放在内边距内。

< style type = "text/css" >

< h1 >软件开发,成就梦想</ h1 >
< form method = "post" >
< div >
< label for = "name" class = "title" >用户名:</ label >
< input type = "text" id = "name" name = "name" />
</ div >
< div >
< label for = "password" class = "title" >密码:</ label >
< input type = "password" id = "password" name = "password" />
</ div >
< div >
< span class = "title" >性别:</ span >
< input type = "radio" name = "gender" id = "male" value = "M" />
< label for = "male" >男</ label >
< input type = "radio" name = "gender" id = "female" value = "F" />
< label for = "female" >女</ label >< br />
</ div >
< div class = "submit" >
< input type = "submit" value = "提交" id = "submit" />
</ div >
</ form >
</ body >
</ html >

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 |
