  This skill provides comprehensive knowledge for building static websites with Hugo static site generator. It should be used when setting up Hugo projects (blogs, documentation sites, landing pages, portfolios), integrating Tailwind CSS v4 for custom styling, integrating headless CMS systems (Sveltia CMS or TinaCMS), deploying to Cloudflare Workers with Static Assets, configuring themes and templates, and preventing common Hugo setup errors.

  Use this skill when encountering these scenarios: scaffolding new Hugo sites, choosing between Hugo Extended and Standard editions, integrating Tailwind CSS v4 with Hugo Pipes, configuring hugo.yaml or hugo.toml files, integrating PaperMod or other themes via Git submodules, setting up Sveltia CMS or TinaCMS for content management, deploying to Cloudflare Workers or Pages, troubleshooting baseURL configuration, resolving theme installation errors, fixing frontmatter format issues (YAML vs TOML), preventing date-related build failures, setting up PostCSS with Hugo, or setting up CI/CD with GitHub Actions.

# Hugo Static Site Generator

**Status**: Production Ready
**Last Updated**: 2025-11-04
**Dependencies**: None (Hugo is a standalone binary)
**Latest Versions**: hugo@0.152.2+extended, PaperMod@latest, Sveltia CMS@latest

---

## Quick Start (5 Minutes)

### 1. Install Hugo Extended

**CRITICAL**: Always install Hugo **Extended** edition (not Standard) unless you're certain you don't need SCSS/Sass support. Most themes require Extended.

```bash
# macOS
brew install hugo

# Linux (Ubuntu/Debian)
wget https://github.com/gohugoio/hugo/releases/download/v0.152.2/hugo_extended_0.152.2_linux-amd64.deb
sudo dpkg -i hugo_extended_0.152.2_linux-amd64.deb

# Verify Extended edition
hugo version  # Should show "+extended"
```

**Why this matters:**
- Hugo Extended includes SCSS/Sass processing
- Most popular themes (PaperMod, Academic, Docsy) require Extended
- Standard edition will fail with "SCSS support not enabled" errors
- Extended has no downsides (same speed, same features + more)

### 2. Create New Hugo Site

```bash
# Use YAML format (not TOML) for better CMS compatibility
hugo new site my-blog --format yaml

# Initialize Git
cd my-blog
git init

# Add PaperMod theme (recommended for blogs)
git submodule add --depth=1 https://github.com/adityatelange/hugo-PaperMod.git themes/PaperMod
```

**CRITICAL:**
- Use `--format yaml` to create hugo.yaml (not hugo.toml)
- YAML is required for Sveltia CMS and recommended for TinaCMS
- TOML has known bugs in Sveltia CMS beta
- Git submodules require `--recursive` flag when cloning later

### 3. Configure and Build

```yaml
# hugo.yaml - Minimal working configuration
baseURL: "https://example.com/"
title: "My Hugo Blog"
theme: "PaperMod"
languageCode: "en-us"
enableRobotsTXT: true

params:
  ShowReadingTime: true
  ShowShareButtons: true
  defaultTheme: auto  # Supports dark/light/auto
```

```bash
# Create first post
hugo new content posts/first-post.md

# Run development server (with live reload)
hugo server

# Build for production
hugo --minify

# Output is in public/ directory
```

---

## The 7-Step Setup Process

### Step 1: Installation and Verification

**Install Hugo Extended** using one of these methods:

**Method 1: Homebrew (macOS/Linux)** ✅ Recommended
```bash
brew install hugo
```

**Method 2: Binary Download (Linux)**
```bash
# Check latest version: https://github.com/gohugoio/hugo/releases
VERSION="0.152.2"
wget https://github.com/gohugoio/hugo/releases/download/v${VERSION}/hugo_extended_${VERSION}_linux-amd64.deb
sudo dpkg -i hugo_extended_${VERSION}_linux-amd64.deb
```

**Method 3: Docker**
```bash
docker run --rm -it -v $(pwd):/src klakegg/hugo:ext-alpine
```

**Method 4: NPM Wrapper** (not recommended, may lag behind)
```bash
npm install -g hugo-bin
```

**Verification:**
```bash
hugo version
# Should output: hugo v0.152.2+extended
#                                ^^^^^^^^ Must show "+extended"
```

**Key Points:**
- Extended edition required for SCSS/Sass
- Version should be v0.149.0+ for best compatibility
- NPM wrapper may be behind official releases
- Pin version in CI/CD (see Step 7)

### Step 2: Project Scaffolding

**Create new site with YAML configuration:**

```bash
hugo new site my-site --format yaml
cd my-site
```

**Directory structure created:**
```
my-site/
├── hugo.yaml          # Configuration (YAML format)
├── archetypes/        # Content templates
│   └── default.md
├── content/           # All your content goes here
├── data/              # Data files (JSON/YAML/TOML)
├── layouts/           # Template overrides
├── static/            # Static assets (images, CSS, JS)
├── themes/            # Themes directory
└── public/            # Build output (generated, git ignore)
```

**CRITICAL:**
- Use `--format yaml` for CMS compatibility
- Never commit `public/` directory to Git
- Create `.gitignore` immediately (see Step 3)

### Step 3: Theme Installation

**Recommended Method: Git Submodule** ✅

```bash
# Popular themes:
# - PaperMod (blogs): https://github.com/adityatelange/hugo-PaperMod
# - Book (docs): https://github.com/alex-shpak/hugo-book
# - Academic (research): https://github.com/HugoBlox/theme-academic-cv
# - Ananke (general): https://github.com/theNewDynamic/gohugo-theme-ananke

git submodule add --depth=1 https://github.com/adityatelange/hugo-PaperMod.git themes/PaperMod
```

**Alternative: Hugo Modules** (advanced)
```bash
hugo mod init github.com/username/my-site

# In hugo.yaml:
# module:
#   imports:
#     - path: github.com/adityatelange/hugo-PaperMod
```

**Add theme to hugo.yaml:**
```yaml
theme: "PaperMod"
```

**When cloning project with submodules:**
```bash
git clone --recursive https://github.com/username/my-site.git
# Or if already cloned:
git submodule update --init --recursive
```

**Key Points:**
- Git submodules are recommended over manual downloads
- `--depth=1` saves space (no theme history)
- Always run `git submodule update --init --recursive` after clone
- Hugo Modules are more advanced but don't require Git submodules

### Step 4: Configuration

**hugo.yaml - Complete Example (PaperMod blog):**

```yaml
baseURL: "https://example.com/"
title: "My Hugo Blog"
theme: "PaperMod"
languageCode: "en-us"
defaultContentLanguage: "en"
enableRobotsTXT: true
buildDrafts: false
buildFuture: false
buildExpired: false
enableEmoji: true

minify:
  disableXML: true
  minifyOutput: true

params:
  env: production
  title: "My Hugo Blog"
  description: "A blog built with Hugo and PaperMod"
  author: "Your Name"
  ShowReadingTime: true
  ShowShareButtons: true
  ShowPostNavLinks: true
  ShowBreadCrumbs: true
  ShowCodeCopyButtons: true
  defaultTheme: auto  # dark, light, auto

  socialIcons:
    - name: twitter
      url: "https://twitter.com/username"
    - name: github
      url: "https://github.com/username"

menu:
  main:
    - identifier: posts
      name: Posts
      url: /posts/
      weight: 10
    - identifier: about
      name: About
      url: /about/
      weight: 20

outputs:
  home:
    - HTML
    - RSS
    - JSON  # Required for search
```

**Configuration Formats:**
- **YAML** (recommended): `hugo.yaml` - Better CMS compatibility
- **TOML** (legacy): `hugo.toml` - Default but problematic with Sveltia CMS
- **JSON**: `hugo.json` - Rarely used

**Environment-Specific Configs:**
```
config/
├── _default/
│   └── hugo.yaml
├── production/
│   └── hugo.yaml  # Overrides for production
└── development/
    └── hugo.yaml  # Overrides for local dev
```

### Step 5: Content Creation

**Create content with Hugo CLI:**
```bash
# Blog post
hugo new content posts/my-first-post.md

# Page
hugo new content about.md

# Nested documentation
hugo new content docs/getting-started/installation.md
```

**Frontmatter Format (YAML recommended):**

```yaml
---
title: "My First Post"
date: 2025-11-04T10:00:00+11:00
draft: false
tags: ["hugo", "blog"]
categories: ["General"]
description: "A brief description for SEO"
cover:
  image: "/images/cover.jpg"
  alt: "Cover image"
---

# Post content starts here

This is my first Hugo blog post!
```

**TOML Frontmatter (for reference only):**
```toml
+++
title = "My First Post"
date = 2025-11-04T10:00:00+11:00
draft = false
tags = ["hugo", "blog"]
+++
```

**Key Points:**
- Use `---` delimiters for YAML frontmatter
- Use `+++` delimiters for TOML frontmatter
- `draft: false` required for post to appear in production
- `date` in future = post won't publish (unless `--buildFuture` flag used)
- Content goes after frontmatter closing delimiter

### Step 6: Build and Development

**Development server (with live reload):**
```bash
# Start server
hugo server

# With drafts visible
hugo server --buildDrafts

# With future-dated posts
hugo server --buildFuture

# Bind to specific port
hugo server --port 1314

# Access at: http://localhost:1313
```

**Production build:**
```bash
# Basic build
hugo

# With minification (recommended)
hugo --minify

# With specific baseURL (for deployment)
hugo --minify --baseURL https://example.com

# Or use environment variable
hugo --minify -b $CF_PAGES_URL
```

**Build Output:**
- All generated files go to `public/` directory
- Typical build time: <100ms for small sites, <5s for 1000+ pages
- Hugo is the **fastest** static site generator

**Key Points:**
- Development server has live reload (HMR)
- Production build should use `--minify`
- Never commit `public/` directory
- Build time is extremely fast (Hugo is written in Go)

### Step 7: Cloudflare Workers Deployment

**Create wrangler.jsonc:**

```jsonc
{
  "name": "my-hugo-site",
  "compatibility_date": "2025-01-29",
  "assets": {
    "directory": "./public",
    "html_handling": "auto-trailing-slash",
    "not_found_handling": "404-page"
  }
}
```

**Manual deployment:**
```bash
# Build site
hugo --minify

# Deploy to Workers
npx wrangler deploy
```

**GitHub Actions (Automated):**

Create `.github/workflows/deploy.yml`:

```yaml
name: Deploy to Cloudflare Workers

on:
  push:
    branches: [main]

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4
        with:
          submodules: recursive  # Important for theme submodules!

      - name: Setup Hugo
        uses: peaceiris/actions-hugo@v2
        with:
          hugo-version: '0.152.2'
          extended: true

      - name: Build
        run: hugo --minify

      - name: Deploy to Cloudflare Workers
        uses: cloudflare/wrangler-action@v3
        with:
          apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
```

**Key Points:**
- `assets.directory` must be `"./public"` (Hugo's output)
- `html_handling: "auto-trailing-slash"` handles Hugo's URL structure
- `not_found_handling: "404-page"` serves Hugo's 404.html
- Always pin Hugo version in CI/CD (prevents version mismatch errors)
- Use `submodules: recursive` for theme submodules

---

## Critical Rules

### Always Do

✅ **Install Hugo Extended** (not Standard) - required for SCSS/Sass support in themes
✅ **Use YAML configuration** (`--format yaml`) - better CMS compatibility than TOML
✅ **Add themes as Git submodules** - easier updates and version control
✅ **Set correct baseURL** - prevents broken asset links on deployment
✅ **Pin Hugo version in CI/CD** - prevents version mismatch errors between local and deployment
✅ **Add `public/` to .gitignore** - build output should not be committed
✅ **Use `draft: false`** - drafts don't appear in production builds
✅ **Clone with `--recursive` flag** - ensures theme submodules are fetched
✅ **Use relative paths for images** - `/images/photo.jpg` not `../images/photo.jpg`
✅ **Test build before deploying** - catch errors locally with `hugo --minify`

### Never Do

❌ **Don't install Hugo Standard** - most themes require Extended edition
❌ **Don't use TOML config with Sveltia CMS** - has known bugs, use YAML instead
❌ **Don't commit `public/` directory** - it's generated output, not source code
❌ **Don't use different Hugo versions** - local vs CI/CD version mismatch causes errors
❌ **Don't forget `submodules: recursive`** - themes won't load in CI/CD
❌ **Don't hardcode production URLs** - use `-b $CF_PAGES_URL` or environment configs
❌ **Don't push `resources/_gen/`** - generated assets, should be in .gitignore
❌ **Don't use future dates carelessly** - posts won't publish until date passes
❌ **Don't skip `.hugo_build.lock`** - add to .gitignore
❌ **Don't mix YAML and TOML** - stick to one format throughout project

## Known Issues Prevention

This skill prevents **9** documented issues:

### Issue #1: Version Mismatch (Hugo vs Hugo Extended)
**Error**: `Error: SCSS support not enabled`
**Source**: https://gohugo.io/troubleshooting/faq/#i-get-this-feature-is-not-available-in-your-current-hugo-version
**Why It Happens**: Theme requires SCSS/Sass processing, but Hugo Standard doesn't include it
**Prevention**: Always install Hugo Extended edition. Verify with `hugo version | grep extended`

### Issue #2: baseURL Configuration Errors
**Error**: Broken CSS/JS/image links, 404s on all assets
**Source**: Hugo docs, Cloudflare Pages guide
**Why It Happens**: `baseURL` in config doesn't match deployment URL
**Prevention**:
- Use environment-specific configs (`config/production/hugo.yaml`)
- Or use build flag: `hugo -b $CF_PAGES_URL`
- Or set correct baseURL in hugo.yaml before build

### Issue #3: TOML vs YAML Configuration Confusion
**Error**: Sveltia CMS fails to parse frontmatter, config not loading
**Source**: Sveltia CMS documentation, community reports
**Why It Happens**: Mixing TOML and YAML, or using TOML with Sveltia CMS (which has bugs)
**Prevention**: Standardize on YAML format. Create sites with `--format yaml` flag

### Issue #4: Hugo Version Mismatch (Local vs Deployment)
**Error**: Features work locally but fail in CI/CD, or vice versa
**Source**: GitHub Actions hugo-setup, Cloudflare Pages docs
**Why It Happens**: Different Hugo versions have different features/bugs
**Prevention**:
- Pin Hugo version in `hugo.yaml` metadata or README
- Set `HUGO_VERSION` in Cloudflare Pages
- Use `hugo-version: '0.152.2'` in GitHub Actions

### Issue #5: Content Frontmatter Format Errors
**Error**: Content files don't render, build fails with parse errors
**Source**: Hugo content management documentation
**Why It Happens**: Wrong delimiters (`---` vs `+++`), invalid YAML/TOML syntax
**Prevention**:
- YAML: use `---` delimiters
- TOML: use `+++` delimiters
- Validate frontmatter with Sveltia CMS or YAML linter

### Issue #6: Theme Not Found Errors
**Error**: `Error: module "PaperMod" not found`, blank site
**Source**: Hugo themes documentation
**Why It Happens**: Theme not installed, or `theme` not set in config, or Git submodules not initialized
**Prevention**:
- Set `theme: "PaperMod"` in hugo.yaml
- Use `git submodule add` for theme installation
- Always `git submodule update --init --recursive` after clone

### Issue #7: Date Time Warp Issues
**Error**: Content missing on deployed site but visible locally
**Source**: Hugo date handling documentation
**Why It Happens**: Future-dated posts published locally (with `--buildFuture`) but not in production
**Prevention**:
- Use current or past dates in frontmatter
- Or add `--buildFuture` flag to production build
- Check `date` field in frontmatter

### Issue #8: Public Folder Conflicts
**Error**: Stale content on site, Git conflicts in `public/`
**Source**: Hugo project structure best practices
**Why It Happens**: Committing `public/` directory when it should be build output only
**Prevention**:
- Add `public/` to `.gitignore`
- Rebuild on every deployment
- Never commit generated files

### Issue #9: Module Cache Issues
**Error**: `failed to extract shortcode`, corrupted module cache
**Source**: Hugo modules documentation, GitHub issues
**Why It Happens**: Corrupted Hugo Modules cache (when using modules instead of submodules)
**Prevention**:
- Run `hugo mod clean` to clear cache
- Run `hugo mod tidy` periodically
- Or use Git submodules instead of modules (more reliable)

- `buildDrafts: false` - prevents drafts in production
- `enableRobotsTXT: true` - SEO best practice
- `minifyOutput: true` - smaller file sizes
- `defaultTheme: auto` - respects user's system preference
- `JSON` output - enables client-side search
- Social icons - improves discoverability

### wrangler.jsonc (Cloudflare Workers)

```jsonc
{
  "name": "my-hugo-site",
  "compatibility_date": "2025-01-29",
  "assets": {
    "directory": "./public",
    "html_handling": "auto-trailing-slash",
    "not_found_handling": "404-page"
  }
}
```

**Why these settings:**
- `directory: "./public"` - Hugo's build output
- `html_handling: "auto-trailing-slash"` - matches Hugo's URL structure
- `not_found_handling: "404-page"` - serves Hugo's custom 404.html

### .gitignore (Essential)

```gitignore
# Hugo
/public/
/resources/_gen/
.hugo_build.lock

# OS
.DS_Store
Thumbs.db

# Editor
.vscode/
.idea/
*.swp
*.swo

# Dependencies (if using npm for tools)
node_modules/
package-lock.json

# Logs
*.log
```

## Sveltia CMS Integration (Recommended)

### Why Sveltia CMS for Hugo?

✅ **Hugo is Sveltia's primary use case** - designed specifically for Hugo
✅ **Simple setup** - 2 static files, no build step required
✅ **No npm dependencies** - single CDN script
✅ **Local backend** - test CMS locally without Git
✅ **YAML frontmatter** - fully compatible
✅ **No security vulnerabilities** - lightweight, maintained
✅ **Active development** - focused on static site generators

### Setup (5 Minutes)

**1. Create admin interface** - `static/admin/index.html`:

```html
<!doctype html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width,initial-scale=1" />
    <title>Content Manager</title>
  </head>
  <body>
    <script src="https://unpkg.com/@sveltia/cms/dist/sveltia-cms.js" type="module"></script>
  </body>
</html>
```

**2. Create CMS config** - `static/admin/config.yml`:

```yaml
backend:
  name: git-gateway
  branch: main

local_backend: true  # Enable local testing

media_folder: "static/images/uploads"
public_folder: "/images/uploads"

collections:
  - name: "blog"
    label: "Blog Posts"
    folder: "content/posts"
    create: true
    slug: "{{slug}}"
    fields:
      - {label: "Title", name: "title", widget: "string"}
      - {label: "Description", name: "description", widget: "string", required: false}
      - {label: "Date", name: "date", widget: "datetime"}
      - {label: "Draft", name: "draft", widget: "boolean", default: false}
      - {label: "Tags", name: "tags", widget: "list", required: false}
      - {label: "Categories", name: "categories", widget: "list", required: false}
      - {label: "Cover Image", name: "cover", widget: "object", required: false, fields: [
          {label: "Image", name: "image", widget: "image", required: false},
          {label: "Alt Text", name: "alt", widget: "string", required: false}
        ]}
      - {label: "Body", name: "body", widget: "markdown"}

  - name: "pages"
    label: "Pages"
    folder: "content"
    create: true
    slug: "{{slug}}"
    filter: {field: "type", value: "page"}
    fields:
      - {label: "Title", name: "title", widget: "string"}
      - {label: "Date", name: "date", widget: "datetime"}
      - {label: "Type", name: "type", widget: "hidden", default: "page"}
      - {label: "Draft", name: "draft", widget: "boolean", default: false}
      - {label: "Body", name: "body", widget: "markdown"}
```

**3. Rebuild site**:
```bash
hugo
# Admin interface now at: http://localhost:1313/admin
```

**4. Production OAuth** (for Git backend):

Sveltia CMS needs OAuth for GitHub/GitLab authentication in production. Use Cloudflare Workers for OAuth proxy:

See bundled reference: `references/sveltia-integration-guide.md`

### Key Points:
- Admin accessible at `/admin` after build
- `local_backend: true` allows local testing without Git
- YAML frontmatter format required
- Collections map to Hugo content directories
- Media files saved to `static/images/uploads`

---

## TinaCMS Integration (Not Recommended)

⚠️ **Use Sveltia CMS instead**. TinaCMS has significant limitations for Hugo:

### Why Not TinaCMS?

❌ **React-only visual editing** - Hugo is Go-templated, visual editing won't work
❌ **Complex setup** - requires Node.js server or Tina Cloud
❌ **692 npm packages** - vs Sveltia's 1 CDN script
❌ **7 security vulnerabilities** - (4 high, 3 critical as of 2025-11-04)
❌ **React/Next.js focused** - Hugo is secondary use case
❌ **YAML only** - same limitation as Sveltia, without benefits

### If You Must Use TinaCMS

Only consider TinaCMS if:
- Already using Tina Cloud
- Have React expertise available
- Need Tina-specific features

See bundled reference: `references/tinacms-integration-guide.md` (warning: not recommended)

## Tailwind CSS v4 Integration

Hugo supports Tailwind CSS v4 through Hugo Pipes and the Tailwind CLI. This approach is fundamentally different from Vite-based React projects.

### When to Use Tailwind vs Themes

**Use Tailwind with Hugo when:**
- Building custom designs without relying on themes
- Need utility-first CSS workflow
- Want complete styling control
- Prefer Tailwind over SCSS/Sass

**Use themes (PaperMod, Book, etc.) when:**
- Want proven, production-ready designs
- Need fast setup without custom CSS
- Happy with theme customization options
- Don't need pixel-perfect custom design

### Key Differences from Vite + React

**CRITICAL:** Do NOT try to use the `tailwind-v4-shadcn` skill patterns with Hugo. That skill is for Vite + React projects and is incompatible with Hugo's asset pipeline.

| Aspect | Vite + React | Hugo |
|--------|-------------|------|
| **Build System** | JavaScript (Node.js) | Go (Hugo binary) |
| **Tailwind Integration** | `@tailwindcss/vite` plugin | Tailwind CLI + PostCSS |
| **Config File** | `vite.config.ts` | `hugo.yaml` |
| **Content Scanning** | `content: []` globs | `hugo_stats.json` |
| **Dev Server** | Vite (port 5173) | Hugo (port 1313) |
| **Dark Mode** | React ThemeProvider | CSS classes or Alpine.js |

### Quick Start (10 Minutes)

1. **Install Dependencies**

```bash
npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init
```

2. **Configure Hugo** (`hugo.yaml`)

```yaml
build:
  writeStats: true  # Generates hugo_stats.json for Tailwind

module:
  mounts:
    - source: assets
      target: assets
    - source: hugo_stats.json
      target: assets/watching/hugo_stats.json
```

3. **Configure Tailwind** (`tailwind.config.js`)

```javascript
module.exports = {
  content: [
    './hugo_stats.json',
    './layouts/**/*.html',
    './content/**/*.{html,md}',
  ],
  darkMode: 'class',
  theme: {
    extend: {
      colors: {
        primary: '#0066cc',
      },
    },
  },
  plugins: [],
}
```

4. **Configure PostCSS** (`postcss.config.js`)

```javascript
module.exports = {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},
  },
}
```

5. **Create CSS Entry File** (`assets/css/main.css`)

```css
@import "tailwindcss";

@layer base {
  body {
    @apply bg-white dark:bg-gray-900 text-gray-900 dark:text-gray-100;
  }
}
```

6. **Process CSS in Template** (`layouts/_default/baseof.html`)

```html
<head>
  {{ $style := resources.Get "css/main.css" | resources.PostCSS }}
  {{ if hugo.IsProduction }}
    {{ $style = $style | minify | fingerprint }}
  {{ end }}
  <link rel="stylesheet" href="{{ $style.RelPermalink }}">
</head>
```

7. **Start Development**

```bash
hugo server
```

### Tailwind-Specific Issues

Common issues when using Tailwind with Hugo (all documented with solutions in reference guide):

| Issue | Cause | Solution |
|-------|-------|----------|
| **CSS not processing** | PostCSS not configured | Verify `resources.PostCSS` in template |
| **Classes not purging** | `hugo_stats.json` not generated | Enable `writeStats: true` in `hugo.yaml` |
| **Dark mode broken** | Wrong config | Use `darkMode: 'class'` in `tailwind.config.js` |
| **Asset fingerprinting fails** | Incorrect Hugo Pipes usage | Use `RelPermalink` not `Permalink` |
| **Hugo template syntax in CSS** | Can't use `{{ }}` in CSS | Apply classes in templates, not CSS |
| **Version mismatch** | CLI vs PostCSS plugin | Update all to same version |

## Advanced Topics

### Custom Shortcodes

Create reusable content components:

```go-html-template
<!-- layouts/shortcodes/youtube.html -->
<div class="youtube-embed">
  <iframe
    src="https://www.youtube.com/embed/{{ .Get 0 }}"
    allowfullscreen>
  </iframe>
</div>
```

Usage in content:
```markdown
{{< youtube dQw4w9WgXcQ >}}
```

### Image Processing

Hugo has built-in image processing:

```go-html-template
{{ $image := resources.Get "images/photo.jpg" }}
{{ $resized := $image.Resize "800x" }}
<img src="{{ $resized.RelPermalink }}" alt="Photo">
```

### Taxonomy Customization

Create custom taxonomies beyond tags/categories:

```yaml
# hugo.yaml
taxonomies:
  tag: tags
  category: categories
  series: series  # Custom taxonomy
```

### Data Files

Use JSON/YAML/TOML data files:

```yaml
# data/team.yaml
- name: Alice
  role: Developer
- name: Bob
  role: Designer
```

Access in templates:
```go-html-template
{{ range .Site.Data.team }}
  <div>{{ .name }} - {{ .role }}</div>
{{ end }}
```

## Troubleshooting

### Problem: "SCSS support not enabled" error
**Solution**: Install Hugo Extended, not Standard. Verify with `hugo version | grep extended`

### Problem: Blank site after deployment
**Solution**:
1. Check `theme` is set in hugo.yaml
2. Verify theme exists in `themes/` directory
3. Run `git submodule update --init --recursive`

### Problem: Assets (CSS/JS/images) not loading
**Solution**:
1. Check `baseURL` in hugo.yaml matches deployment URL
2. Or use `hugo -b https://your-site.com`
3. Or use environment-specific config

### Problem: Posts not appearing on site
**Solution**:
1. Check `draft: false` in frontmatter
2. Check date is not in future
3. Or build with `--buildDrafts` and `--buildFuture` flags

### Problem: Theme not found in CI/CD
**Solution**: Add `submodules: recursive` to checkout action in GitHub Actions

### Problem: Sveltia CMS not loading
**Solution**:
1. Rebuild site with `hugo`
2. Check `/admin` directory exists in `public/`
3. Verify `config.yml` syntax
4. Check browser console for errors
