<!DOCTYPE html> < html > < head > < title >单选按钮对齐</ title > < style type = "text/css" > div { margin: 10px; padding-bottom: 10px; max-360px; } .title { float: left; 100px; text-align: right; padding-right: 10px;} .submit { text-align: right;} </ style > </ head > < body > < 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-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 |
