Sync CSS-Tricks Articles

Fetch articles from the CSS-Tricks author page and create blog entries for any missing ones in src/content/blog/.

Process

  1. Fetch author page: WebFetch https://css-tricks.com/author/zellwk/ — extract all article titles and URLs. Only page 1 unless user requests more.

  2. Find missing articles: For each article, search src/content/blog/ by grepping for the CSS-Tricks URL and searching by title keywords. Read the frontmatter of potential matches to confirm — filenames can be misleading.

  3. For each missing article, fetch its page to get:

    • Publication date (from article metadata)
    • A one-sentence summary for the description

  4. Create blog entry files using the format below.

External Article Format

---
title: Article Title Here
description: 'One-sentence description of the article's core argument or insight.'
url: https://css-tricks.com/article-slug/
external: CSS Tricks
tags: ['relevant', 'tags']
---

Add updateDate to the frontmatter of the article if it exists.

File Naming

{YYYY-MM-DD}-{slug}.mdx where date is from the CSS-Tricks publication date and slug is a short kebab-case version of the title.

Examples:

  • 2025-10-20-honeypot-field.mdx
  • 2026-01-26-no-need-to-trap-focus-dialog.mdx
  • 2026-02-02-vscode-theming-building-extension.mdx

Descriptions

  • One sentence, in double quotes in the frontmatter
  • Describe the core argument or insight, not just the topic
  • Use em dashes for asides

Tags

Common tags: css, javascript, accessibility, tailwind, vscode, typography, layouts, design, theming, splendidlabz, astro, svelte

Check existing articles for conventions.

Gotchas

  • Verify matches by reading frontmatter, not just filenames — content can be wrong in the file
  • Duplicate dates are fine — multiple articles can share the same date
  • Search multiple ways — by URL, title keywords, and filename patterns to avoid false negatives
