feat: add custom Bootstrap styling with SCSS support

Browse Source 
Implement SCSS-based custom styling system to enable Bootstrap customization while maintaining CDN delivery for core framework.

Changes:
- Add Hugo Pipes SCSS processing pipeline using css.Sass
- Create modular SCSS file structure (main.scss, _variables.scss, _custom.scss)
- Implement custom typography (base font size 1.25rem, adjusted heading sizes)
- Add custom link colors (#0b0089 primary, #0052a3 hover)
- Configure CSS minification and SHA-384 fingerprinting for cache busting
- Add comprehensive SCSS styling documentation

Technical details:
- Updated baseof.html to compile SCSS with Hugo Pipes
- CSS loads after Bootstrap CDN for proper cascade
- Minified output (~154 bytes)
- Supports live reload in development mode

# Custom SCSS Styling
This document describes the SCSS-based custom styling system for the markusgraf.ch Hugo site.
## Overview
The site uses a hybrid approach for styling:
- **Bootstrap 5.3.2** loaded from CDN (core framework)
- **Custom SCSS** compiled via Hugo Pipes (overrides and custom styles)
This approach provides the benefits of Bootstrap's CDN (speed, caching) while allowing complete customization through SCSS.
## File Structure
```
assets/scss/
├── main.scss # Main entry point (imports all partials)
├── _variables.scss # Bootstrap variable overrides
└── _custom.scss # Custom component styles
```
### main.scss
The main entry point that Hugo processes. This file imports all SCSS partials in the correct order.
### _variables.scss
Bootstrap variable overrides for customizing design tokens:
- Heading font sizes (h1-h6)
- Link colors and hover states
- Spacing scale (optional)
- Any other Bootstrap variables
### _custom.scss
Custom component styles and utilities that extend Bootstrap or add new styles.
## How It Works
### Compilation Process
1. Hugo reads `assets/scss/main.scss`
2. Hugo processes SCSS with `css.Sass` function
3. Output is minified (`outputStyle: compressed`)
4. CSS is fingerprinted with SHA-384 for cache busting
5. Integrity hash is added to the `<link>` tag
### CSS Load Order
In `layouts/_default/baseof.html`:
```html
<!-- Bootstrap CDN CSS (base styles) -->
<link href="https://cdn.jsdelivr.net/.../bootstrap.min.css" rel="stylesheet">
<!-- Custom compiled CSS (overrides) -->
<link rel="stylesheet" href="/css/main.[fingerprint].css" integrity="sha384-...">
```
This order ensures custom styles cascade over Bootstrap defaults.
## Customization Guide
### Changing Heading Sizes
Edit `assets/scss/_variables.scss`:
```scss
$h1-font-size: 3rem; // Make h1 larger
$h2-font-size: 2.25rem; // Make h2 larger
```
### Changing Link Colors
Edit `assets/scss/_variables.scss`:
```scss
$link-color: #0066cc; // Primary link color
$link-hover-color: #0052a3; // Hover state color
```
### Adding Custom Component Styles
Edit `assets/scss/_custom.scss`:
```scss
.navbar-brand {
font-weight: 700;
letter-spacing: 0.05em;
}
.card {
border-radius: 8px;
box-shadow: 0 2px 4px rgba(0,0,0,0.1);
}
```
### Adding New SCSS Partials
1. Create a new file: `assets/scss/_mypartial.scss`
2. Import it in `main.scss`: `@import 'mypartial';`
## Development Workflow
### Development Mode
```bash
hugo server
```
- SCSS changes trigger automatic recompilation
- Browser live-reloads with updated styles
- Source maps are available for debugging
### Production Build
```bash
hugo build
```
- SCSS is compiled with minification
- No source maps are included
- CSS is fingerprinted for cache busting
## Performance
- Custom CSS file size: ~154 bytes (current)
- Minified and compressed
- Cached via fingerprinting
- Minimal impact on page load
## Best Practices
1. **Keep it minimal** - Only override what you need
2. **Use SCSS features** - Variables, nesting, mixins when beneficial
3. **Organize by concern** - Use partials to separate different types of styles
4. **Comment your code** - Explain why specific overrides are needed
5. **Test in multiple browsers** - Ensure compatibility
## Troubleshooting
### SCSS Won't Compile
Check Hugo version supports `css.Sass` (v0.128.0+):
```bash
hugo version
```
### Styles Not Applying
1. Check CSS load order in browser DevTools
2. Verify fingerprinted CSS file exists in `public/css/`
3. Check for SCSS syntax errors in Hugo output
### Cache Issues
The fingerprinting ensures cache busting, but during development you can:
```bash
hugo server --disableFastRender
```

## Why
The site currently uses Bootstrap 5.3.2 from CDN with default styling. To establish a unique visual identity and brand consistency, we need the ability to customize Bootstrap variables (font sizes, colors, spacing) and add custom styles without modifying the core framework.
## What Changes
- Add Hugo SCSS/SASS processing pipeline using Hugo Pipes
- Create custom SCSS file structure for Bootstrap variable overrides and custom styles
- Maintain Bootstrap CSS from CDN for core framework
- Compile custom styles to supplement Bootstrap defaults
- Enable customization of heading font sizes, link colors, and other design tokens
## Impact
- Affected specs: `styling` (new capability)
- Affected code:
- `layouts/_default/baseof.html` - Update to include compiled custom CSS
- `assets/scss/` - New directory for SCSS files
- `hugo.toml` - May need configuration for SCSS processing
- No breaking changes to existing functionality
- Performance: Minimal impact, adds one additional CSS file (~few KB)

## ADDED Requirements
### Requirement: SCSS Processing Pipeline
The system SHALL process SCSS files using Hugo Pipes to generate custom CSS that supplements Bootstrap's CDN-provided styles.
#### Scenario: SCSS compilation on build
- **WHEN** Hugo builds the site
- **THEN** SCSS files in `assets/scss/` are compiled to CSS
- **AND** the compiled CSS is fingerprinted for cache busting
- **AND** the resulting CSS file is included in the HTML output
#### Scenario: Development mode with live reload
- **WHEN** running Hugo in development mode (hugo server)
- **THEN** SCSS changes trigger automatic recompilation
- **AND** the browser live-reloads with updated styles
### Requirement: Bootstrap Variable Customization
The system SHALL allow customization of Bootstrap design tokens through SCSS variables without modifying the CDN-provided Bootstrap CSS.
#### Scenario: Override heading font sizes
- **WHEN** custom heading sizes are defined in SCSS variables
- **THEN** the compiled CSS applies these sizes to heading elements
- **AND** the Bootstrap CDN CSS is loaded first (base styles)
- **AND** custom CSS is loaded after (overrides)
#### Scenario: Override link colors
- **WHEN** custom link colors are defined in SCSS variables
- **THEN** links across the site use the custom colors
- **AND** link hover states use appropriate custom colors
#### Scenario: Override spacing scale
- **WHEN** custom spacing values are defined
- **THEN** elements using those spacing classes reflect the custom values
### Requirement: Custom Style Organization
The system SHALL organize custom styles in a maintainable SCSS file structure following Hugo and SASS best practices.
#### Scenario: Main SCSS entry point
- **WHEN** Hugo processes SCSS
- **THEN** a single main SCSS file serves as the entry point
- **AND** this file imports Bootstrap variable overrides
- **AND** this file imports custom component styles
- **AND** this file imports custom utility styles
#### Scenario: Modular SCSS files
- **WHEN** developers add new custom styles
- **THEN** styles can be organized into separate partial files
- **AND** partial files are imported into the main SCSS file
- **AND** file naming follows SCSS conventions (e.g., `_variables.scss`, `_custom.scss`)
### Requirement: CSS Output Integration
The system SHALL integrate compiled custom CSS into the base layout template alongside Bootstrap CDN CSS.
#### Scenario: CSS load order
- **WHEN** a page is rendered
- **THEN** Bootstrap CDN CSS loads first
- **AND** custom compiled CSS loads second
- **AND** CSS files include integrity hashes where applicable
- **AND** the custom CSS file path includes a fingerprint for cache busting
#### Scenario: Production build optimization
- **WHEN** building for production
- **THEN** SCSS is compiled with minification
- **AND** the output CSS is optimized for file size
- **AND** source maps are not included in production builds
