思路复盘
顶部搜索模块：一个.search-index大盒子里有两个小盒子（.search&.user）
*大盒子设置display：flex；.search盒子设置flex：1；保证页面拉大时搜索框跟着变大
*小盒子里的图标使用伪元素选择器制作，简化HTML结构
局部导航栏模块：一个.local-nav的大盒子里放五个a，每个a里面装两个span盒子
*大盒子设置display：flex；每个a盒子设置flex：1；使大盒子被平均分成五份，每个a各占一份
*每个a盒子也设置display：flex；&flex-direction：column；&align-items：center；使a盒子里面的内容水平居中
其他的几个主要的盒子思路都和这个差不多了

知识点浅解
背景线性渐变：background:linear-gradient（起始方向，颜色1，颜色2，颜色3，…）；
盒子阴影：box-shadow：水平阴影的位置，垂直阴影的位置，阴影的模糊范围，阴影颜色；
eg：box-shadow：1px,1px,4px,rgba(0,0,0,0.2);
