vue全家桶+element-UI搭建后台管理系统（2）“:引入基本样式和图标库”

1、在想assets文件下，新建css,images,js文件，用来存放公用文件

    在css->normalize.css

/*! normalize.css v2.0.1 | MIT License | git.io/normalize */

/* ==========================================================================
   HTML5 display definitions

    display: block;
}

/*

    display: inline-block;
}

/*

    display: none;
    height: 0;
}

html {
    font-family: sans-serif; /* 1 */
    -webkit-text-size-adjust: 100%; /* 2 */
    -ms-text-size-adjust: 100%; /* 2 */
}

/*

body {
    margin: 0;
}

/* ==========================================================================

/*

 */

a:focus {
    outline: thin dotted;
}

/*

 */

a:active,
a:hover {
    outline: 0;
}

/* ==========================================================================
   Typography
   ========================================================================== */

/*
 * Addresses `h1` font sizes within `section` and `article` in Firefox 4+,

 */

h1 {
    font-size: 2em;
}

/*

    font-style: italic;
}

/*

 */

mark {
    background: #ff0;
    color: #000;
}


/*
 * Corrects font family set oddly in Safari 5 and Chrome.
 */

code,
kbd,
pre,
samp {
    font-family: monospace, serif;
    font-size: 1em;
}

/*
 * Improves readability of pre-formatted text in all browsers.
 */

pre {
    white-space: pre;
    white-space: pre-wrap;
    word-wrap: break-word;
}

/*
 * Sets consistent quote types.
 */

q {
    quotes: "\201C" "\201D" "\2018" "\2019";
}

/*
 * Addresses inconsistent and variable font size in all browsers.
 */

small {
    font-size: 80%;
}

/*

 */

sub,
sup {
    font-size: 75%;
    line-height: 0;
    position: relative;
    vertical-align: baseline;
}

sup {
    top: -0.5em;
}

sub {
    bottom: -0.25em;
}

/* ==========================================================================
   Embedded content
   ========================================================================== */

/*

 */

img {
    border: 0;
}

/*

 */

svg:not(:root) {
    overflow: hidden;
}

/* ==========================================================================

   ========================================================================== */

/*
 * Addresses margin not present in IE 8/9 and Safari 5.
 */

figure {
    margin: 0;
}

/* ==========================================================================

/*

 */

fieldset {
    border: 1px solid #c0c0c0;
    margin: 0 2px;
    padding: 0.35em 0.625em 0.75em;
}

/*
 * 1. Corrects color not being inherited in IE 8/9.
 * 2. Remove padding so people aren't caught out if they zero out fieldsets.
 */

legend {
    border: 0; /* 1 */
    padding: 0; /* 2 */
}

/*
 * 1. Corrects font family not being inherited in all browsers.
 * 2. Corrects font size not being inherited in all browsers.
 * 3. Addresses margins set differently in Firefox 4+, Safari 5, and Chrome
 */

button,
input,
select,
textarea {
    font-family: inherit; /* 1 */
    font-size: 100%; /* 2 */
    margin: 0; /* 3 */
}

/*
 * Addresses Firefox 4+ setting `line-height` on `input` using `!important` in
 * the UA stylesheet.
 */

button,
input {
    line-height: normal;
}

/*
 * 1. Avoid the WebKit bug in Android 4.0.* where (2) destroys native `audio`
 *    and `video` controls.
 * 2. Corrects inability to style clickable `input` types in iOS.
 * 3. Improves usability and consistency of cursor style between image-type
 *    `input` and others.
 */

button,
html input[type="button"], /* 1 */
input[type="reset"],
input[type="submit"] {
    -webkit-appearance: button; /* 2 */
    cursor: pointer; /* 3 */
}

/*
 * Re-set default cursor for disabled elements.
 */

button[disabled],
input[disabled] {
    cursor: default;
}

/*
 * 1. Addresses box sizing set to `content-box` in IE 8/9.
 * 2. Removes excess padding in IE 8/9.
 */

input[type="checkbox"],
input[type="radio"] {
    box-sizing: border-box; /* 1 */
    padding: 0; /* 2 */
}

/*
 * 1. Addresses `appearance` set to `searchfield` in Safari 5 and Chrome.
 * 2. Addresses `box-sizing` set to `border-box` in Safari 5 and Chrome
 *    (include `-moz` to future-proof).
 */

input[type="search"] {
    -webkit-appearance: textfield; /* 1 */
    -moz-box-sizing: content-box;
    -webkit-box-sizing: content-box; /* 2 */
    box-sizing: content-box;
}

/*
 * Removes inner padding and search cancel button in Safari 5 and Chrome
 * on OS X.
 */

input[type="search"]::-webkit-search-cancel-button,
input[type="search"]::-webkit-search-decoration {
    -webkit-appearance: none;
}

/*
 * Removes inner padding and border in Firefox 4+.
 */

button::-moz-focus-inner,
input::-moz-focus-inner {
    border: 0;
    padding: 0;
}

/*
 * 1. Removes default vertical scrollbar in IE 8/9.
 * 2. Improves readability and alignment in all browsers.
 */

textarea {
    overflow: auto; /* 1 */
    vertical-align: top; /* 2 */
}

/* ==========================================================================
   Tables
   ========================================================================== */

/*
 * Remove most spacing between table cells.
 */

table {
    border-collapse: collapse;
    border-spacing: 0;
}

2、在App.vue中正确引入normalize.css:

<template>
  <div id="app">
    <router-view/>
  div>
template>

<script>
  import '@/assets/css/normalize.css'
  export default {
    name: 'App'
  }
script>

<style>

style>

3、引入sass:

    

cnpm install node-sass --save-dev //安装node-sass环境

cnpm install sass-loader --save-dev //安装sass-loader

4、为了使用更多更丰富的图标，引入fontawesome图标库，使用方法：点击查看图标使用方法链接

    cnpm install font-awesome

    在main.js引入：

import 'font-awesome/css/font-awesome.css'

基本样式引进来了，接下来使用element-ui提供的组件，搭建自己的管理后台了
