网页布局基础中的2-3编程练习
为什么已经把背景图保存在本地了，并且用了绝对路径和相对路径都试了，就是无法把背景图显现出来
如：.book{background:url(Users/Administrator/Desktop/网页布局基础/case2/images/t_book.gif) no-repeat #eff9f9;}
或者：.book{background:url(E：/Users/Administrator/Desktop/网页布局基础/case2/images/t_book.gif) no-repeat #eff9f9;}
?????????????????????????????????????????????????????????????????????????????????
