    position: fixed;
    right: 16px;
    bottom: 16px;

  • You can use Notepad to open the SVG file you just downloaded, you can see the <svg> information, and copy it all to the new arrow.html file in layouts/partials under the Hugo theme directory.
<svg aria-hidden="true" focusable="false" data-prefix="fas" data-icon="chevron-circle-up" class="svg-inline--fa fa-chevron-circle-up fa-w-16" role="img" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 512 512">
    <path fill="currentColor" d="M8 256C8 119 119 8 256 8s248 111 248 248-111 248-248 248S8 393 8 256zm231-113.9L103.5 277.6c-9.4 9.4-9.4 24.6 0 33.9l17 17c9.4 9.4 24.6 9.4 33.9 0L256 226.9l101.6 101.6c9.4 9.4 24.6 9.4 33.9 0l17-17c9.4-9.4 9.4-24.6 0-33.9L273 142.1c-9.4-9.4-24.6-9.4-34 0z">

# 添加锚点 | Adding anchor

  • 打开Hugo主题目录下layouts/partials中的head.html文件,在任意行添加如下代码,添加锚点。
  • Open the head.html file in layouts/partials under the Hugo theme directory, add the following code to any line, and add an anchor point.
<span id="top"></span>

# 一键返回顶部 | Back to top

  • 回到Hugo主题文件夹下的layoust/_default文件夹下的single.html文件,把下面的代码拷进到{{ define "main" }}之后。再去SSH里Hugo一下就搞定啦。
  • Go back to the single.html file in the layoust/_default folder under the Hugo theme folder and copy the following code after {{ define "main" }}.
<a href="#top" class="backtop">{{ partial "arrow.html" . }}</a>
