dynamicweb11-1这个练习是一个完整的项目代码，页面较多，实现了购物车，登录等功能。项目根目录，创建文件夹App_Themes，其下创建文件夹PetShop1，内含1个文件。stylesheet1.css。根目录，创建文件夹Comm_Images，内含5张图片，button-cart.jpg，button-search.jpg，button-wishlist.jpg，home-fish.jpg，seahorse.jpg。图片呢我就不放了。根目录，创建文件夹Prod_Images，其下创建4个文件夹，Backyard，Birds，Bugs，Fish，每个文件夹下都有商品图片若干。图片我就放一个示例。asp.net动态web开发(021)_ico上代码：stylesheet1.css
