大项目之网上书城(三)——主页(中)

尽量日更,我发现我还要写的东西有好多啊。

主要改动

设计这个勉强看得过去的颜色,填充之前的主页,按照之前的思路,左边是图书分类,中间一个轮播图,然后右边是一个文案广告,加一个热销书推荐,下面是新书推荐,然后下面的右面是新书排行榜。因为我打算把网页弄成动态的,于是热销书推荐,新书推荐,新书排行榜,都要是通过js+servlet来从数据库获取最新数据,写起来会非常麻烦啊。(以及我还没有数据库,我还没有dao,没有BookBean,没有service,于是测试起来超麻烦啊。就只给热销书推荐写了个简单的测试。新书推荐因为涉及到图片,我不太了解,还在发展科技树,真的很艰巨啊。再加上我意识到我要设计一下通用的图书详情页面,我要增加个超级用户。超级用户要可以修改数据库,啊,真的好难啊。任重而道远。)

1.主页持续施工中

代码

真实任重而道远,这里同样加了bootstrap的代码,用来显示按钮。。
