综合演练:Baidu Home Page</p>
2.1 技术点
- box-sizing:让padding向内,占用内容的尺寸
<p>content-box，border和padding不计算入width之内</p>
<p>padding-box，padding计算入width内</p>
<p>border-box，border和padding计算入width之内，其实就是怪异模式了~</p>
- float:让标签左浮动 右浮动
- display:改变标签的类型:参考网址：http://www.baidu.com
- background: url("../images/bg.jpg") /设置背景/
- background-size: cover; /设置背景的尺寸/
- text-decoration: none; /去除下划线/
- font-weight: bolder; /加粗/
- vertical-align: middle; /图片居中/
2.2 风格切换
- 静态实现
- 动态实现
