图片左右滚动

需求：页面显示教师信息列表，列表中每一条数据显示图片滚动插件，每张图片的长宽及长宽比例各不相同。

前提条件：美工把静态页面写好

HTML代码：

@using Models;
@{
    List<cms_content> teacherList = ViewData["teacherList"] as List<cms_content>; //春雨树频道
    PagerModel pager = ViewData["pager"] as PagerModel;
}

<div class="teacherteam_box">
    <h1>教师团队</h1>
    @foreach (cms_content teacher in teacherList)
    {
        <div class="teacher_box">
            <div class="teacher_img fl">
                <img src="~/@teacher.imgUrl" />
            </div>
            <div class="teacher_infor fl">
                <h2>@teacher.title</h2>
                <p>
                    @teacher.description
                </p>
                <div class="products_box">
                    <div class="products_pre">

                    </div>
                    <div class="products_next">

            </div>
            <div class="clear"></div>
        </div>
    }
