打印class

和常规的响应式class一样，使用下面的class可以针对打印机隐藏或显示某些内容。

15  下拉菜单  dropdown

class= " dropdown ">  class="btn dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown"> Dropdown class="caret"> class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1"> "presentation">"menuitem" tabindex="-1" href="#">Action "presentation">"menuitem" tabindex="-1" href="#">Another action "presentation">"menuitem" tabindex="-1" href="#">Something else here "presentation" class="divider"> "presentation">"menuitem" tabindex="-1" href="#">Separated link 改为右对齐 class="dropdown-menu text-right" role="menu" aria-labelledby="dropdownMenu1">

下拉菜单

class= " dropdown ">  class="btn dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown"> Dropdown class="caret"> class="dropdown-menu text-right" role="menu" aria-labelledby="dropdownMenu1"> "presentation" class="dropdown-header">Dropdown header "presentation">"menuitem" tabindex="-1" href="#">Action "presentation">"menuitem" tabindex="-1" href="#">Another action "presentation">"menuitem" tabindex="-1" href="#">Something else here "presentation" class="divider"> "presentation" class="dropdown-header">Dropdown header "presentation">"menuitem" tabindex="-1" href="#">Separated link

主要是添加了

Dropdown header  里面有个.dropdown-header的样式类。

16 、  导航  nav

Bootstrap中可用的导航有相似的标记，用基类.nav开头，这是相似的部分。改变修饰类可以改变样式。

1、标签页

注意.nav-tabs类需要.nav基类。

class="nav nav-tabs">class="active">"#">Home"#">Profile"#">Messages

在这里暂时只进行探讨简单的样式。

2、胶囊式标签页

用相同的 HTML 标记，但要用.nav-pills代替。

class="nav nav-pills">class="active">"#">Home"#">Profile"#">Messages

Pills 可以竖直堆叠。只要加上.nav-stacked。

 

使用下拉菜单

class="nav nav-tabs">class="dropdown"> class="dropdown-toggle" data-toggle="dropdown" href="#"> Dropdown class="caret"> class="dropdown-menu">"#">Home"#">Profile"#">Messages "#">Home"#">Profile"#">Messages

6、带下拉菜单的胶囊式标签页

class="nav nav-pills">class="dropdown active"> class="dropdown-toggle" data-toggle="dropdown" href="#"> Dropdown class="caret"> class="dropdown-menu">"#">Home"#">Profile"#">Messages "#">Home"#">Profile"#">Messages

 

标签

 简单案例

Example heading class="label label-default">New

Example heading class="label label-default">New

Example heading class="label label-default">New

Example heading class="label label-default">New

Example heading class="label label-default">New

Example heading class="label label-default">New

可用的变体

用下面的任何一个class即可改变标签的外观。

class="label label-default">Default class="label label-primary">Primaryclass="label label-success">Success class="label label-info">Info class="label label-warning">Warning class="label label-danger">Danger

面包屑导航

 用一个带方向的层次表明当前页面的位置。

分割符自动地通过CSS的:before和content添加上了。

class="breadcrumb"> "#">Home "#">Library class="active">Data

17 、分页   pagination

class="pagination">class="disabled">"#">«class="active">1 class="sr-only">(current)"#">2"#">3"#">4"#">5"#">»

class="pager">class="previous">"#">← Olderclass="next">"#">Newer →

18、 警示

可关闭的警告框

可以用一个可选的.alert-dismissable和关闭按钮。

class= " alert alert-warning alert-dismissable ">  " button "  class= " close " data-dismiss= " alert " aria-hidden= " true ">×  Warning! Best check yo self, you ' re not looking too good.

确定在所有设备上的正确行为

一定要给data-dismiss="alert"属性用上。

警告框中的链接

用.alert-link工具类，可以快速提供在任何警告框中相符的颜色。

class= " alert alert-success ">Well done!  "#" class="alert-link">You successfully read this important alert message. class= " alert alert-info ">Well done!  "#" class="alert-link">You successfully read this important alert message. class= " alert alert-warning ">Well done!  "#" class="alert-link">You successfully read this important alert message. class= " alert alert-danger ">Well done!  "#" class="alert-link">You successfully read this important alert message.

19、进度条 class= " progress "> class= " progress-bar " role= " progressbar " aria-valuenow= " 60 " aria-valuemin= " 0 " aria-valuemax= " 100 " style= " width: 60%; ">  class="sr-only">60% Complete

20、列表组加入徽章，它会自动地放在右面。

class="list-group">class="list-group-item">class="badge">14Cras justo odioclass="list-group-item">class="badge">33Dapibus ac facilisis inclass="list-group-item">class="badge">11Morbi leo risusclass="list-group-item">class="badge">41Porta ac consectetur acclass="list-group-item">class="badge">21Vestibulum at eros

标签而不是

标签（也就是说父元素是 而不是 ）。没必要给每个元素都加一个父元素。 class= " list-group ">  "#" class="list-group-item active"> Cras justo odio  "#" class="list-group-item">Dapibus ac facilisis in  "#" class="list-group-item">Morbi leo risus  "#" class="list-group-item">Porta ac consectetur ac  "#" class="list-group-item">Vestibulum at eros

定制内容

在里面可以加几乎任何HTML，甚至是像下面的带链接的列表组。

class= " list-group ">  "#" class="list-group-item active">

class="list-group-item-heading">List group item heading

class="list-group-item-text">Cras sit amet nibh libero, in gravida nulla. n vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.

"#" class="list-group-item">

class="list-group-item-heading">List group item heading

class="list-group-item-text">Cras sit amet nibh libero, in gravida nulla. n vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.

"#" class="list-group-item">

class="list-group-item-heading">List group item heading

class="list-group-item-text">Cras sit amet nibh libero, in gravida nulla. n vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.

21、面板

带表格的面版

为了无缝的设计，在面版中加入.table。如果有.panel-body，就在表格的上方加上一个用于分割的边界。

class= " panel panel-default "> class= " panel-heading ">Panel heading class= " panel-body ">

Some default panel content here. Nulla vitae elit libero, a pharetra augue. Aenean lacinia bibendum nulla sed consectetur. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum. Nullam id dolor id nibh ultricies vehicula ut id elit.

class= " table "> First NameLast NameUser Name aehyok leo @aehyok lynn thl @lynn 22 、提示      主要实现了按钮的上下左右的ToolTip，然后是文本框和链接的ToolTip。 <</span>div class="container" style="margin-top:40px;"> <</span>div class="bs-example tooltip-demo"> <</span>div class="bs-example-tooltips"><</span>button type="button" class="btn btn-default" data-toggle="tooltip"data-placement="left" title="Tooltip on left">左侧Tooltip</</span>button><</span>button type="button" class="btn btn-default" data-toggle="tooltip"data-placement="top" title="Tooltip on top">上方Tooltip</</span>button><</span>button type="button" class="btn btn-default" data-toggle="tooltip"data-placement="bottom" title="Tooltip on bottom">下方Tooltip</</span>button> <</span>button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="right" title="Tooltip on right">右侧Tooltip</</span>button> </</span>div> </</span>div><</span>input type="text" id="testt" rel="tooltip" title="123456" /><</span>a href="#" data-toggle="tooltip" title="Default tooltip">dsafsdfasdfasdfasd</</span>a> </</span>div> 23、弹出框 四个方向  " margin-left:200px;margin-top:100px;margin-bottom:200px; "  class= " bs-example tooltip-demo "> class= " bs-example-tooltips ">  " button "  class= " btn btn-default " data-container= " body "data-toggle= " popover " data-placement= " left " data-content= " Vivamus sagittis lacus vel augue laoreet rutrum faucibus.
