flex项目实战php中文网移动端首页

整体实现思路

整个页面分为：头部header、轮播图banner、导航nav 、主体main、尾部footer五大部份。
1.1 头部header: 用户头像、logo 、用户导航，水平排列

1.2 轮播图banner：可点图片a+img

1.3 导航nav:2个无序列表ul垂直排列。每个ul中4个列表li水平排列。li内是可点击a的1张图片img和图片说明span。

1.4 主体main：
主体main分为：推荐课程recomment、最新更新renew、最新文章article、最新博文blog、最新问答quan五部分垂直排列。

1.5 尾部footer：4个字体图标和说明span水平排列，每个字体图标和说明span垂直排列。

效果图

总结：
第一次没有完全老师代码的作业，过程很艰难。结果不知道合格不合格。但是个人觉得进步很大，感常见蛮有成就感的。

不足之处：就是基础不牢固，需要慢慢补充。

提问老师：布局之外的其它样式，比如宽高，字体……是须要通过不断写代码积累的吗？还是通过什么工具测量的？

Teacher's comments：大家才学习不到二周的课程, 能写到如此地步, 已经相当不错了
