圖標(biāo) Iconfont
在項(xiàng)目開發(fā)過程中經(jīng)常會(huì)遇到小圖標(biāo)的使用問題，小圖標(biāo)的使用可以讓程序更美觀。在這里推薦使用 IconFont，這是阿里巴巴的矢量圖標(biāo)庫。
在 Iconfont 中有很多圖標(biāo)，我們可以像逛超市一樣，挑選自己喜歡的商品，然后放入購物車。
使用步驟如下：
第一步：拷貝項(xiàng)目下面生成的 fontclass 代碼
//at.alicdn.com/t/font_6fwsxglzew154s4i.css
第二步：挑選相應(yīng)圖標(biāo)并獲取類名，應(yīng)用于頁面

使用 Element 布局
- npm 安裝
npm install element-ui --save
- 引入項(xiàng)目
在main.js中加入以下內(nèi)容：
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-default/index.css'
Vue.use(ElementUI)

項(xiàng)目打包
注意事項(xiàng)：
打開 config/index.js 會(huì)看到一個(gè) build 屬性，這里就是我們打包的基本配置。你在這里可以修改打包的目錄，文件名。最重要的是一定要把絕對(duì)路徑改為相對(duì)路徑。
把
assetsPublicPath: '/'
改為
assetsPublicPath: './'
