1, ul, ol < ;span style="color:red;">Desequence:
class=“list-unstyled“
2, ul, ol Horizontal arrangement span> (Change the vertical list into a horizontal list, remove the bullets (numbers), and keep the horizontal display)
class=“list-inline”
3. dl horizontal list (when the screen is larger than 768px, add the class name ".dl-horizontal" ” has the horizontal definition list effect)
class=“dl-horizontal”
The method of use is very simple, just add the corresponding class name to the
tag
img-responsive: Responsive images, mainly for responsive design
img-rounded: 圆角图片 img-circle: 圆形图片 img-thumbnail: 缩略图片

Bootstrap The framework also provides you with nearly 200 different icon images, and these icons are all icon effects achieved using the @font-face attribute of CSS3 in conjunction with fonts.
Any row-level element is acceptable, usually span tags are used as icon containers
Can be viewed on the bootstrap website;span>
Usage is very simple, just copy and paste the English under the icon into the class:
<span class="glyphicon glyphicon-ok"></span>
<table class="table"></table>
通过这些状态类可以为行或单元格设置颜色。
Class 描述
.active 鼠标悬停在行或单元格上时所设置的颜色.success 标识成功或积极的动作.info 标识普通的提示信息或动作.warning 标识警告或需要用户注意.danger 标识危险或潜在的带来负面影响的动作
将任何 .table 元素包裹在 .table-responsive 元素内,即可创建响应式表格,其会在小屏幕设备上(小于768px)水平滚动。当屏幕大于 768px 宽度时,水平滚动条消失。
<div class="table-responsive"> <table class="table"> ... </table> </div>
单独的表单控件会被自动赋予一些全局样式。所有设置了 .form-control
类的 <input>
、<textarea>
和 <select>
元素都将被默认设置宽度属性为 width: 100%;。 将 label
元素和前面提到的控件包裹在 .form-group
中可以获得最好的排列。
<form role="form">告诉辅助设备(如屏幕阅读器)这个元素所扮演的角色是个表单</form><form role="button">告诉设备,这是个按钮,可以点击。本质上是增强语义性,增强组件的可访问性、可用性</form>
不要将表单组合输入框组混合使用,建议将输入框组嵌套到表单组中使用。
<form> <div class="form-group"> <label for="exampleInputEmail1">Email address</label> <input type="email" class="form-control" id="exampleInputEmail1" placeholder="Email"> </div> <div class="form-group"> <label for="exampleInputPassword1">Password</label> <input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password"> </div> <div class="form-group"> <label for="exampleInputFile">File input</label> <input type="file" id="exampleInputFile"> <p class="help-block">Example block-level help text here.</p> </div> <div class="checkbox"> <label> <input type="checkbox"> Check me out </label> </div> <button type="submit" class="btn btn-default">Submit</button> </form>
多个控件可以排列在同一行:
<form class="form-inline"> <div class="form-group"> <label for="exampleInputName2">Name</label> <input type="text" class="form-control" id="exampleInputName2" placeholder="Jane Doe"> </div> <div class="form-group"> <label for="exampleInputEmail2">Email</label> <input type="email" class="form-control" id="exampleInputEmail2" placeholder="jane.doe@example.com"> </div> <button type="submit" class="btn btn-default">Send invitation</button> </form>
通过为表单添加 .form-horizontal
类,并联合使用 Bootstrap 预置的栅格类,可以将 label 标签和控件组水平并排布局。这样做将改变 .form-group
的行为,使其表现为栅格系统中的行(row),因此就无需再额外添加 .row 了。
多选框(checkbox)
用于选择列表中的一个或多个选项,而单选框(radio)
用于从多个选项中只选择一个。
设置了disabled
属性的单选或多选框都能被赋予合适的样式。对于和多选或单选框联合使用的
多选框:
<div class="checkbox"> <label> <input type="checkbox" value=""> Option one is this and that—be sure to include why it's great </label></div> <div class="checkbox disabled"> <label><input type="checkbox" value="" disabled> Option two is disabled </label></div>
单选框:
<div class="radio"> <label> <input type="radio" name="optionsRadios" id="optionsRadios2" value="option2"> Option two can be something else and selecting it will deselect option one </label> </div> <div class="radio disabled"> <label> <input type="radio" name="optionsRadios" id="optionsRadios3" value="option3" disabled> Option three is disabled </label> </div>
通过将 .checkbox-inline 或 .radio-inline 类应用到一系列的多选框(checkbox)或单选框(radio)控件上,可以使这些控件排列在一行。
