移動端fixed佈局相容性不好，使用absolute佈局來代替

在移動端使用fixed佈局存在相容性問題，因此使用absolute佈局來代替

效果演示

src/app.vue里打好框架

<template>
  <div id="app" class="g-container">
    <div class="g-header-container">
      頭部導航
    </div>
    <div class="g-view-container">
      <div class="content">
        內容區域
      </div>
      
    </div>
    <div class="g-footer-container">
      底部導航
    </div>
  </div>
</template>

<script>
  export default {
    name: 'App',
  }
</script>

<style scoped>
  .g-container{
    position: relative;
    width:100%;
    height:100%;
    max-width:640px;
    min-width:320px;
    margin:0 auto;
    overflow:hidden;  
  }
  .g-header-container{
    position:absolute;
    left:0;
    top:0;
    width:100%;
    z-index:999;
    height:64px;
    background:pink; 
  }
  .g-view-container{
    height:100%;
    padding-bottom:80px;
    background:lightblue;
    overflow:auto;
  }
  .content{
    height:2000px;
  }
  .g-footer-container{
    position:absolute;
    left:0;
    bottom:0;
    width:100%;
    box-shadow:0 0 10px 0 hsla(0,6%,58%,0.6);
    height:80px;
    z-index:999;
    background:lightgreen;
  }
</style>

在main.js里引入首頁文件的樣式index.scss

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import 'babel-polyfill'
import fastclick from 'fastclick'
import Vue from 'vue'
import App from './App'
import router from './router'

//給預設主頁引入index.scss樣式文件
import 'assets/scss/index.scss';

Vue.config.productionTip = false

//給body元素設置fastclick
fastclick.attach(document.body);

/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<App/>'
})

assets/scss/index.scss

*{
    margin:0;
    padding:0;
}
html,body{
    // 必須設置，否則內容滾動效果無法實現
    width:100%;
    height:100%;
}
