引入阿里巴巴矢量库的图标，也可以自行修改

把下面的js跟css引入到你的网站即可

<!--阿里图标库--> 
<script src="https://at.alicdn.com/t/font_2827587_k24if0ucns.js"></script>
<link rel="stylesheet" type="text/css" href="https://at.alicdn.com/t/font_2827587_k24if0ucns.css">
<style type="text/css">.icon {width: 1em; height: 1em;vertical-align: -0.15em;fill: currentColor;overflow: hidden;}</style>

在footer.php里加上下面这段代码，自行修改

CSS代码

这段css其实是文字的抖动跟适应手机屏幕隐藏底部导航栏(可用可不用，不过@media这段建议保留)

JS代码

这段js代码是用来触发滚动条显示百分比的

更新

分享按钮代码发生了变动，这里我们也做一下修改

<a class="share-btn poster" poster-share="<?php the_ID();?>" title="海报分享" href="javascript:;">
    <svg class="icon" aria-hidden="true"><use xlink:href="#icon-fenxiang"></use></svg>分享
</a>

把这段A标签代码将原先的代码覆盖就完成了
