A minimalist, editorial Jekyll theme for technical blogs and personal portfolios. It powers agusmakmun.github.io.
The design takes its cues from Medium: serif headlines, a comfortable reading column, quiet hairline borders and a single accent green. It also adds tools for developers, such as ⌘K search, code blocks with copy buttons and a sticky table of contents. It's built with plain CSS and a small vanilla JS file: no Bootstrap, no jQuery and no CSS framework.

Reading (Medium-inspired)
- Editorial typography: Newsreader headlines, Source Serif 4 body text, Inter for the UI and JetBrains Mono for code
- Article pages with a large title, author byline, reading time, topic pills and a sticky, auto-generated table of contents with scroll spy
- Dark code blocks with language labels and a copy button (Rouge syntax highlighting)
- Author card, previous/next post links, related posts and Disqus comments
- Share menu (X, LinkedIn, Facebook, Hacker News, email) plus the system share sheet where the browser has one, and copy link
Browsing
- Home page with a sticky profile sidebar and a numbered post list in two views, Compact and Expanded, each with a short excerpt
- Shortened pagination (
1 … 4 5 6 … 20), a/writing/archive grouped by year, and category pages - ⌘K / Ctrl+K search dialog with keyboard navigation (searches titles and categories)
Portfolio
/projects/: open-source and work projects with generated covers (gradient, icon and command line), filtered by tag/about/: bio, career highlights, experience timeline, certifications and a tools icon grid- Live GitHub star count in the header
Under the hood
- Light/dark theme that follows the system setting, can be toggled and is remembered per visitor
- Responsive down to phone width, with a mobile menu
- SEO via jekyll-seo-tag: canonical URLs, Open Graph and large Twitter cards, JSON-LD (
BlogPosting,WebSite,Person) - Every page gets a meta description: a post's own
description, or one generated from its opening text - Default share image (
static/img/og-default.png),robots.txt, standard XML sitemap and RSS feed - A 404 page in the site's design
- Icon font trimmed to only the Material Symbols the site uses
- Cache-busted CSS/JS on each build, HTML minified with Jekyll Compress HTML
- Google Analytics (GA4), loaded only in production and only when an ID is set
- Deployed by GitHub Actions to GitHub Pages (Jekyll 4)

Posts are Markdown files in _posts/, named YYYY-MM-DD-slug.md:
---
layout: post
title: "Your Title"
date: 2026-10-24 20:00:00 +0700
categories: [postgres, nextjs] # each needs a page in category/ (see below)
description: "One or two sentences." # optional: list excerpt, search results and share previews
image: /static/img/_posts/cover.png # optional: share image (defaults to static/img/og-default.png)
---
Your content in Markdown…- Without a
description, one is generated from the post's opening text (code blocks skipped) and used for the list excerpt, search results and share previews. Write your own for important posts. ##and###headings automatically appear in the article's table of contents.- Every category needs a page in
category/. Copy an existing one, e.g.category/django.md, and changecategories,titleandpermalink.
Add an entry to _data/projects.yml under featured (open source with a cover), more (one-line list) or work:
featured:
- name: My Tool
repo: agusmakmun/my-tool # GitHub repo; the card links here
url: https://my-tool.dev # optional: "Site" link
since: 2026
tags: [Python, Django] # used by the tag filter
icon: build # Material Symbols name, https://fonts.google.com/icons
color: '#0c4b33' # cover colour
cmd: pip install my-tool # line shown on the cover
summary: One or two sentences about what it does.Work projects use company and years instead of repo and since. Keep them public-safe: no customer or
employee names, prices, internal hostnames or incidents.
Requirements: Docker for the site, and Node.js only for make format.
make serve # same as: docker compose upOr with Ruby 3.x:
bundle config set --local path vendor/bundle
bundle install
bundle exec jekyll serve --livereloadThen open http://localhost:4000. Pages reload on save; changes to _config.yml or the Gemfile need a restart
(docker compose restart).
make format # Prettier on CSS, JS, YAML and the README (via npx, no package.json needed)
make check # formatting check + production build + internal link check (html-proofer)Liquid templates (_layouts, _includes, *.html pages) and _posts are not run through Prettier on purpose:
it doesn't understand Jekyll's Liquid tags, and reformatting old posts would be noise. The link check skips external
links, the share menu's recipient-less mailto:, and http:// links inside old posts.
Pushing to master runs .github/workflows/pages.yml, which builds with JEKYLL_ENV=production and publishes to
GitHub Pages. In the repository settings, set Pages → Source to GitHub Actions.
The Actions build is required, not optional: GitHub Pages' built-in builder only supports Jekyll 3 and a fixed plugin list,
so it would skip _plugins/auto_description.rb and fail on Jekyll 4. Run make check before pushing.
- Originally forked from A simple grey theme for Jekyll.
- Design inspired by Medium. This is an independent theme, not affiliated with Medium.
- Icons: Material Symbols, brand logos from Simple Icons (CC0), tool icons on the About page from skillicons.dev.
