UI框架-Bootsrap
什么是BootStrap？
BootStrap来自Twitter，是目前最受欢迎的响应式前端框
Bootstrap是基于HTML、CSS、JavaScript的，它简洁灵活，使得Web开发更加快捷
为什么使用Bootstrap？
移动设备优先：自Bootstrap3起，框架包含了贯穿于整个库移动设备优先的样式。
- 不是简单的增加一些可选的针对移动设备的样式，而是直接融合进了框架的内核中
- 也就是说，针对移动设备的样式融合进了框架的每个角度，而不是增加一个额外的文件浏览器支持：所有的主流浏览器支持Bootstrap
容易上手：只要您具备HTML和CSS基础知识，您就可以开始学习Bootstrap
响应式设计：Bootstrap的响应式CSS能够自适应于台式机、平板电脑和手机
它为开发人员创建接口提供了一个简洁统一的解决方案
它包含了功能强大的内置组件、易于定制
它还提供了基于Web的定制
它是开源的

表格
和之前的表格相比，标签更丰富更加语义化，效果更加美观
丰富的表格
< table>为表格添加基础样式
< thead>表格 表格行 的容器元素（< tr>）
< tbody>表格主体的表格行的容器元素（< tr>）
< tr>表格行
< td>默认的表格单元格
< th>特殊的表格单元格，（居中和加粗的效果）。必须在< thead>内使用
< caption>关于表格存储内容的描述或总结
好看的类样式
.table为任意< table>添加基本样式（只有横向分割线）
.table-striped 在< tbody>内添加斑马线形式的条纹（IE8不支持），隔行变色
.table-bordered为所有表格的单元格添加边框
.table-hover在< tbody>内的任一行启用鼠标悬停状态，鼠标悬停高亮突出显示
.table-condensed让表格更加紧凑
情景色类样式
适合应用在< th>、< tr> 、< td>
table-active激活效果（悬停颜色）
table-success表示成功或积极的动作
table-info表示普通的提示信息或动作
table-warning表示警告或需要用户注意
