##                               手把手教你用element ui搭建后台基础框架 ##

element ui和iview都是vue常用的框架，今天用了一下element ui搭建了一个基础版的后台框架，这里就和大家分享下，首先看一下效果图：

**实现步骤：**

**1、项目使用vue-cli脚手架2搭建，怎么创建脚手架之前博客已经写过，首先引入element-ui,我这里使用较多，就全局引入了，方式如下：**

使用如下命令安装

npm i element-ui -S

main.js里面引入

import ElementUI from 'element-ui';
    import 'element-ui/lib/theme-chalk/index.css';
    
    Vue.use(ElementUI);

2、background.vue

<template>
    <transition name="bounce"
      enter-active-class="bounceInLeft"
      leave-active-class="bounceOutRight">
      <div class='backgroundWrapper'>
        <div class="backgroundTop">
            <div class="logoWrapper">
                <div class="logoImg" :style="{backgroundImage:`url(${imageUrl})`}" @click="handleGoHome()">
                </div>
                <div class="logoText">中国联通</div>
            </div>
            <div class="backgroundRight">
                <div class="nickname">spirits</div>
                <div class="quitWrapper" @click="handleQuit()">退出</div>
            </div>
        </div>
        <div class="menuWrapper" ref="menuContent">
            <div class="leftWrapper" :style="{height: leftHeight}">

此文件你还需要安装less、动画transition、css里面还引入了一个variable.styl

variable.styl如下，放在assets下的css文件夹下：

// 背景色
    $color-background = #f5f5f5
    
    // 主题色
    $color-theme = #ED6D00
    $color-theme-1 = #1eb7a7
    
    // 蒙层
    $color-layer = rgba(0, 0, 0, 0.4)
    $color-layer-1 = rgba(255, 255, 255, 0.4)
    
    // 字体颜色，由浅到深
    $color-text-1 = #333333
    $color-text-2 = #666666   // 与字体“huawenxihei”搭配
    $color-text-3 = #999999
    $color-text-4 = #d3d3d3
    $color-text-5 = #ffffff
    
    // 边框颜色
    $color-border = #E0E0E0
    $color-white = #ffffff
    // 阴影
    $box-shadow = 0 0 12px #dfdfdf
    // 分割线（横线、竖线）颜色
    $color-divider = #e2e2e2
    
    // 价格颜色, 星级评分颜色
    $color-price = #00ceb9
    $color-level = #ff9c00
    
    $font-size-large = 20px
    $font-size-title = 15px
    $font-size-desc = 13px
    $font-size-small = 11px
    
    // 板块间间距
    $margin-bottom-module = 10px
    $margin-top-module = 10px
    
    // 板块内边距 板块内部上下边距为20px; 板块内元素间左右边距为10px;
    
    
    // 图片类圆角5px, 其他圆角3px
    $border-radius-img = 5px
    $border-radius-other = 3px

恭喜你到此时你就可以看到效果了。
