百分比布局得应用 —— 模仿京东移动端首页

写在前面
我想，我要更多的去练习，去搭建页面结构，去分析页面结构。
emmmmmm，一个下午就画了小半个页面。我想我应该反思(面壁思过)。好了好了，开始撸思路了。夜里再来个flex布局。
移动端开发的布局方式
流式百分比布局、flex弹性布局、rem+媒体查询。
主要就是这三种吧，今天简单说下流式百分比布局，它的主要核心就是宽度用百分比表示，利用百分比进行布局。
一般在移动开发时，需要给body设置最小宽度和最大宽度的，为了使页面能使用手机屏幕。今天画页面画了一下午，emmmm，一个首页还没有画完。。。。。 只做出来简单的几部分。先看下效果吧(捂脸捂脸)
是的 ，它就是长着这个样子。主要目的就是简单练习一下百分比布局的思想。
可是是写PC端页面写多了，很不习惯写移动端页面。写着写着感觉自己不会操作了。功夫不到家啊还是，还得多练习。
