今天开始我们用前面学的各种布局技巧，模仿php中文网移动端的首页做一个网页出来。过程不容易，最终呈现的效果还是可以的，下面先上代码。

导航栏以前我们是用左浮动去做的，现在会了flex布局之后，要做一个导航栏非常简单，我们只需要将ul变成一个flex盒子，里面的子元素就会自动横向排列了。因为头部和底部是一直固定在窗口上面和下面的，所以是用fixed固定定位去做，把头部底部固定在窗口。
banner图因为还没学习js，所以做不到轮播的效果，就放了一张图片上去。但是因为头部是用固定定位，已经脱离了文档流，所以banner图会有一部分会被头部覆盖掉，我是给banner图加上一个margin-top，把他顶下来。
导航栏也是用ul标签来做的，这里有个小技巧，因为导航栏有两行，我们就用两个ul，这样我们不用考虑两行的问题，只要解决掉一行就可以了。也是用flex自动填充空间的特性，很简单就能够把导航栏做出来了。
下面的课程列表样式挺像的有很多样式是可以复用的，通过flex，浮动或者是绝对定位都可以把效果实现出来。不过目前我写的代码自适应的地方很少，有很多地方的宽度啊，高度啊是用px写死了，如果设备的宽高发生变化，现在看的很正常的画面有可能会变形。这个是之后要去思考和提升的地方。我观察php中文网，是根据宽度自适应显示多少字进去，但是我这边字体只能是自己去删减，但是如果屏幕宽度再缩小的话，还是会变形，不知道这个是后端通过什么去实现的。
底部的代码跟导航栏是很像的，把背景颜色改一改就行了。
通过这个仿前端的实战训练，我对电脑端和移动端的页面设计基本上都能开发了，之后就是不断去仿页面，去熟练自己的代码。
