缩略图组件

缩略图在网站中最常用的就是产品列表页面，一行显示几张图片，有的在图片底下带有标题、描述内容、按钮等信息。bootstrap框架将这部分独立成一个模块组件，通过类名.thumbnail配合bootstrap的网格系统来实现。下面是bootstrap缩略图组件不同版本的源码文件：

LESS :  tbumbnails.less

SASS : _tbumbnails.scss

实现原理：

布局的实现主要依靠于bootstrap框架的网格系统，下面是缩略图对应的样式

<span style="color: #800000">.thumbnail </span>{<span style="color: #ff0000">
  display</span>:<span style="color: #0000ff"> block</span>;<span style="color: #ff0000">

效果如下：

可以用火狐响应式设计视图查看

在仅有缩略图的基础上，添加一个类名为.caption的div容器，在这个容器中放置其他内容，如：标题，文本描述，按钮等

<span style="color: #0000ff"><span style="color: #800000">div </span><span style="color: #ff0000">class</span><span style="color: #0000ff">="container"</span><span style="color: #0000ff">></span>

警示框组件

bootstrap框架通过.alert样式来实现警示框效果，在默认情况下，bootstrap提供了四种不同的警示框效果：

1、成功警示框：提示用户操作成功，在.alert的基础上追加.alert-success样式；

2、信息警告框：给用户提供提示信息，在.alert的基础上追加.alert-info样式；

3、警告警示框：提供警告信息，在.alert的基础上追加.alert-warning样式；

4、错误警示框：提示用户操作错误，在.alert的基础上追加.alert-danger样式；

其中，.alert样式主要设置了警示框的背景色、边框，圆角，文字颜色，此外还对h4、p、ul及.alert-link做了样式上的处理，下面是css源码：

<span style="color: #800000">.alert </span>{<span style="color: #ff0000">

  border-radius</span>:<span style="color: #0000ff"> 4px</span>;
}<span style="color: #800000">
.alert h4 </span>{<span style="color: #ff0000">

.alert > ul </span>{<span style="color: #ff0000">

}<span style="color: #800000">

可关闭的警示框

1、在默认的警示框的容器上追加一个.alert-dismissable类名

2、在button标签中添加.close，实现警告框的关闭按钮

3、确保关闭按钮元素上设置了自定义属性data-dismiss=”alert“（关闭警示框需要通过js来检测该属性，从而控制警示框的关闭）

例子：

<span style="color: #0000ff"><span style="color: #800000">div </span><span style="color: #ff0000">class</span><span style="color: #0000ff">="alert alert-success alert-dismissable"</span><span style="color: #ff0000"> role</span><span style="color: #0000ff">="alert"</span><span style="color: #0000ff">></span>

警示框的链接

有时候需要在警示框中加入链接，告诉用户跳转到新的页面，bootstrap框架中对警示框的链接做了高亮处理。给警告框加的链接添加一个为.alert-link的类名，下面是alert-link的css样式

<span style="color: #800000">.alert .alert-link </span>{<span style="color: #ff0000">
  font-weight</span>:<span style="color: #0000ff"> bold</span>;
