上篇hexo博客建设和主题优化(1)
下篇hexo博客建设和主题优化(3)

主题目录下_config.yml 配置文件：

# 配置网站favicon和网站LOGO ## 本地 #favicon: /favicon.png #logo: /medias/logo.png # 此处我用的CDN，本地文件也可以使用 favicon: https://cdn.jsdelivr.net/gh/guixinchn/image/blog/favicon.png logo: https://cdn.jsdelivr.net/gh/guixinchn/image/blog/logo.png 

图片资源在主题目录中\themes\hexo-theme-matery\source\medias下面 , 外链图片也可以使用.

实现方法，介绍 js 主题文件下的文件 /source/js/ 下新建 funnyTitle.js，添加以下代码：

var OriginTitle = document.title;  var titleTime;  document.addEventListener('visibilitychange', function () { 
              if (document.hidden) { 
                  $('[rel="icon"]').attr('href', "https://cdn.jsdelivr.net/gh/guixinchn/image/blog/favicon.png");          document.title = 我相信你会回来的！;          clearTimeout(/span>titleTime); } else { 
          $('[rel="icon"]').attr('href', "https://cdn.jsdelivr.net/gh/guixinchn/image/blog/favicon.png"); document.title = '哈哈，我就知道！' + OriginTitle; titleTime = setTimeout(function () { 
          document.title = OriginTitle; }, 2000); } }); 

然后在主题目录下的/layout/layout.ejs 引入

<script src="<%- theme.jsDelivr.url %><%- url_for('/js/funnyTitle.js') %>"></script>

打开主题目录下的 /layout/about.ejs 文件，新增如下代码：

<div class="card-content article-card-content">
   <div class="title center-align" data-aos="zoom-in-up">
      <i class="fa fa-address-book">i>  <%- __('个人简历') %>
   div>
   <div id="articleContent" data-aos="fade-up">
      <%- page.content %>
   div>
div>

在主题目录下的/layout/about.ejs 文件里面关于下面代码中的profile相关信息从主题的 _config.yml 配置文件中获取.

<div class="profile center-align">
    <div class="avatar">
        <img src="<%- theme.jsDelivr.url %><%- url_for(theme.profile.avatar) %>" alt="<%- config.author %>" class="circle responsive-img avatar-img">
    div>
    <div class="author">
        <div class="post-statis hide-on-large-only" data-aos="zoom-in-right">
            <%- partial('_partial/post-statis') %>
        div>
        <div class="title"><%- config.author %>div>
        <div class="career"><%- theme.profile.career %>div>
        <div class="social-link hide-on-large-only" data-aos="zoom-in-left">
            <%- partial('_partial/social-link') %>
        div>
    div>
div>

主题目录下的 _config.yml 配置文件中profile信息配置, 可以修改…

# profile in about page, including avatars, career, and personal introductions.
# 在”关于”页面中配置个人信息，包括头像、职业和个人介绍.
profile:
  avatar: /medias/avatar.jpg
  career: Software Engineer
  introduction: If you wish to succeed, you should use persistence as your good friend, experience as your reference, prudence as your brother and hope as your sentry.

原来的主题没有404页面，首先在主题目录下的/source/目录下新建一个404.md，内容如下：

---
title: 404
date: 2017-07-19 16:41:10
type: "404"
layout: "404"
description: "你访问的页面被外星人叼走了 :("
---

然后在主题目录下新建一个/layout/404.ejs文件，内容如下：

<style type="text/css"> /* don't remove. */ .about-cover { 
           height: 90.2vh; } style>
<div class="bg-cover pd-header about-cover">
    <div class="container">
        <div class="row">
            <div class="col s10 offset-s1 m8 offset-m2 l8 offset-l2">
                <div class="brand">
                    <div class="title center-align">
                        404
                    div>
                    <div class="description center-align">
                        <%= page.description %>
                    div>
                div>
            div>
        div>
    div>
div>

<% if (theme.banner.enable) { %>
    <script> // 每天切换 banner 图. Switch banner image every day. var bannerUrl = "<%- theme.jsDelivr.url %><%- url_for('/medias/banner/') %>" + new Date().getDay() + '.jpg'; $('.bg-cover').css('background-image', 'url(' + bannerUrl + ')'); script>
<% } else { %>
    <script> $('.bg-cover').css('background-image', 'url(<%- theme.jsDelivr.url %><%- url_for('/medias/banner/0.jpg') %>)'); script>
<% } %>

根据自己需要修改主题目录下的/layout/_partial/footer.ejs文件, 可以设置站点访问量, 访问人数, 字数统计, 站点运行时间, 网站备案等信息.

<footer class="page-footer bg-color">
    <% if (theme.music.enable && theme.music.fixed) { %>
        <%- partial('_widget/music') %>
    <% } %>

    <div class="container row center-align" style="margin-bottom: <% if (theme.time.enable) { 
             %>15<% } else { 
             %>0<% } %>px !important;">
        <div class="col s12 m8 l8 copy-right">
            Copyright ©
            <% if (theme.time.year !== new Date().getFullYear()) { %>
                <span id="year"><%- theme.time.year %>-<%- new Date().getFullYear() %>span>
            <% } else { %>
                <span id="year"><%- theme.time.year %>span>
            <% } %>

           daysTip = '本站已运行 ' + diffDays + ' 天'; } else if (language === 'zh-HK') {

            <% } %>
                     |

        <div class="col s12 m4 l4 social-link <%- socialClass %>">
            <%- partial('_partial/social-link') %>
        div>
    div>
footer>

还可以添加百度不蒜子统计

找到/layout/_partial/footer.ejs 文件，修改对应样式为

<!--总访问人数-->
<% if (theme.busuanziStatistics && theme.busuanziStatistics.totalNumberOfvisitors) { 
         %>
<span id="busuanzi_container_site_uv" style="display: inline">
