第12章 综合案例—社区新闻网
习题解答 | 金阳光社区网
编程题
1. 制作社区网的个人注册页面，如图 12-7 所示。
这道题要做一个完整的注册页面。观察效果图，页面由三部分组成：
- 页头区域：顶部细红条、暗色纹理 Logo 区（左侧"金阳光社区网"大标题 + 右侧宣传语）、搜索栏、红色导航栏
- 注册表单区：白色卡片，"立即注册"左标题 + "已有账户，直接登录"右链接，居中"个人注册"副标题，包含登录名称、所在地区、姓名、手机号、邮箱、密码、重复密码、推荐人、验证码共9个字段，深色"立即注册"提交按钮
- 页脚区域：深色背景版权文字
关键实现要点：
- 所在地区用三个 <select> 下拉框并排（省、市、县/区）
- 表单字段用 label + input 对齐，必填字段在标签前加红色星号
* - 验证码图片旁边放"看不清？换一张"链接
完整代码如下（register.html）：

- 面包屑导航：首页 > 在线调查，右上角显示位置路径
- 调查表单：标题"对农产品认知情况的调查"，发布时间 2020-07-23
- Q1：下拉框选择省市区/县（与注册页一致）
- Q2：单选（男/女）
- Q3：单选（4个年龄段）
- Q4：单选（5个学历选项）
- Q5：单选（6个专业方向）
- Q6：单选（6个职业选项）
- Q7：多选复选框（6个关注领域）
- Q8：文本域（50字以内的建议）
- 底部：深色"提交"按钮

</html>📖 参见 12.3 制作社区新闻网的列表页（左右两栏布局复用）
3. 制作社区网的图片新闻页面，如图 12-9 所示。
这道题要做一个内容丰富的图片新闻聚合页。观察效果图，页面分为几个版块：
- 页头：与其他页一致（Logo、搜索、导航）
- 主内容区（上部，左右布局）：
- 左列"爱心点点"：竖向排列的捐款记录列表，每条有序号、100%、日期
- 中列"公益新动"：图文混排，左图右文列表形式，每条新闻有大图+标题+简介
- 右列"紧急救援"：与公益新动格局相同
- 图片区版块（助学圆梦、紧急救援、公益活动）：每个版块有深色标题条，下方展示4-5张图片横排，图片下方有"标题"文字
完整代码如下（gongyixinwen.html）：
