这篇博客通过四个实战案例介绍了Bootstrap的使用，包括利用媒体对象实现搜索书籍页面，使用表格布局购物车页面，借助模态框展示购物车订单信息，以及图标组件的应用。每个案例都提供了相应的代码示例和效果展示。
首先我们来看一下思维导图：
案例一：实现搜索书籍页面（我们用媒体对象：Media object）
代码如下：

<!-- 引入Bootstrap的样式-->

.navbar-collapse{
flex-grow: 0;/* 固定容器中 1代表弹性过大占用父容器剩余空间 0代表不占用 */
}
.form-group{
width: 300px;/* 宽度 */
margin-left: auto;/* 左间距自适应 自动 */
margin-right: auto;/* 右间距自适应 自动 */
margin-top: 31px;/* 100-38=62/2=31px 居中*/
}
.ss{
height: 100px;/* 高度 */
margin-top: 30px;/* 上间距 */
background-color: #DCDCDC;/* 背景颜色 */
}
.list-group,.media{
margin-top: 30px;
}
.media-body p{
line-height: 15px;
}
.media-body p button{

line-height: 10px;
