前端框架之Bootstrap框架
下载地址:https://v3.bootcss.com/,下载Bootstrap3版本
下载之后把文件中不需要的文件都删掉
需要获取的样式代码,可以直接从这些地方找到,然后复制
一、HTML页面导入文件,因为Bootstrap要依赖于jquery,所以也要把jquery导进来
二、布局容器
Bootstrap需要为页面内容和栅格系统包裹一个.container容器。有两种:
一、 container 左边和右边留有空白的容器布局
二、 container-fluid 类似于100%宽度,占据全部视口的容器
三、栅格系统
系统会自动将一行分为12列
行(row),列(column)

四、表格
table-bordered为表格和每个单元格增加边框
table-hover 为每一行对鼠标悬停状态做出相应
table-striped 给tbody内的每一行增加斑马条纹样式
