This personal website use a Hugo theme called harbor with some of customized adjustments.

Here are the customizations,

• Enable KaTex by following this harbor tutorial.
  1. Create a file under ~/themes/harbor/layouts/partials/math.html.

     <!-- html file under ~/themes/harbor/layouts/partials/math.html -->
     
     </script>
     <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/katex@0.16.4/dist/katex.min.css" integrity="sha384-vKruj+a13U8yHIkAyGgK1J3ArTLzrFGBbBc0tDp4ad/EyewESeXE/Iv67Aj8gKZ0" crossorigin="anonymous">
     <script defer src="https://cdn.jsdelivr.net/npm/katex@0.16.4/dist/katex.min.js" integrity="sha384-PwRUT/YqbnEjkZO0zZxNqcxACrXe+j766U2amXcgMg5457rve2Y7I6ZJSm2A0mS4" crossorigin="anonymous"></script>
     <script defer src="https://cdn.jsdelivr.net/npm/katex@0.16.4/dist/contrib/auto-render.min.js" integrity="sha384-+VBxd3r6XgURycqtZ117nYw44OOcIax56Z4dCRWbxyPt0Koah1uHoK0o4+/RRE05" crossorigin="anonymous"
         onload="renderMathInElement(document.body);"></script>

  2. Add the following code in ~/themes/harbor/layouts/_default/single.html.

     {{ if or .Params.math .Site.Params.math }}
         {{ partial "math.html" . }}
     {{ end }}

• Instead of using Disqus, I use utterances as the comment tool which sync comments to github issues.
  1. Create a file under ~/themes/harbor/layouts/partials/utterances.html

     <!-- html file under ~/themes/harbor/layouts/partials/utterances.html -->
     
     <script src="https://utteranc.es/client.js"
         repo="choux130/myblog-yintingchou"
         issue-term="title"
         label="comments 💬"
         theme="github-light"
         crossorigin="anonymous"
         async>
     </script>

  2. Edit the following code block in ~/themes/harbor/layouts/_default/single.html.

     {{ if  (not (isset .Params "disable_comments")) }}
     <!-- {{ partial "disqus.html" . }} -->
     {{ partial "utterances.html" . }}
     {{ end }}

  • Goodbye, Disqus! Hello, Utterances!
• Change the page Archives's layout by editing the following code block in ~/themes/harbor/layouts/archives/single.html

  <table class="archives">
      <!-- <tbody>
      {{ range (where (where .Site.Pages ".Section" "post") "Kind" "page") }}
          <tr>
          <td>
              {{ .Date | dateFormat "2006" }}&nbsp;{{ .Date | dateFormat "Jan" }}&nbsp;{{ .Date | dateFormat "2" }}
          </td>
          <td>
              <p>
              <a href="{{ .Permalink }}" title="{{ .Title }}"
                  >{{ .Title }}</a
              >
              </p>
          </td>
          </tr>
      {{ end }}
      </tbody> -->
  
      {{ $updated_year := .Site.LastChange.Format "2006" }}
      {{ range (where (where .Site.Pages ".Section" "post") "Kind" "page").GroupByDate "2006" -}}
      <tbody>
          {{ if eq .Key $updated_year }}
          <tr>
              <td  style="padding-left: 0px; padding-top:0px;">
              <strong style="font-size: 25px;">{{ .Key }}</strong>
              </td>
          </tr>
          {{ else }}
          <tr>
              <td  style="padding-left: 0px; padding-top:15px;">
              <strong style="font-size: 25px;">{{ .Key }}</strong>
              </td>
          </tr>
          {{ end }}
          
          {{ range .Pages }}
          <tr>
              <td>
              {{ .Date | dateFormat "Jan" }}&nbsp;{{ .Date | dateFormat "2" }}
              </td>
              <td>
              <p>
                  <a href="{{ .Permalink }}" title="{{ .Title }}"
                  >{{ .Title }}</a
                  >
              </p>
              </td>
          </tr>
          {{ end }}
      </tbody>
      {{ end }}
  </table>    

• Move tag's location in the post to the top by changind the code in ~/themes/harbor/layouts/_default/single.html.

  <article class="article" class="blog-post">
    <!-- {{ partial "toc.html" . }} -->
  
    {{ if or .Params.math .Site.Params.math }}
      {{ partial "math.html" . }}
    {{ end }}
  
    {{ if .Params.tags }}
      <div class="blog-tags">
        {{ range .Params.tags }}
          <a
            href="{{ "" | absLangURL }}tags/{{ . | urlize }}{{ if $.Site.Params.uglyurls }}.html{{ else }}/{{ end }}"
            >{{ . }}</a
          >&nbsp;
        {{ end }}
      </div>
    {{ end }}
  
    {{ partial "toc.html" . }}
