From bf52fda68f60129371db6a66782df1f655dc91db Mon Sep 17 00:00:00 2001 From: Markus Graf Date: Mon, 27 Oct 2025 22:04:52 +0100 Subject: [PATCH] feat: add custom Bootstrap styling with SCSS support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- assets/scss/_custom.scss | 14 ++ assets/scss/_variables.scss | 57 ++++++ assets/scss/main.scss | 8 + docs/SCSS_STYLING.md | 163 ++++++++++++++++++ layouts/_default/baseof.html | 6 + .../add-custom-bootstrap-styling/proposal.md | 18 ++ .../specs/styling/spec.md | 65 +++++++ .../add-custom-bootstrap-styling/tasks.md | 30 ++++ 8 files changed, 361 insertions(+) create mode 100644 assets/scss/_custom.scss create mode 100644 assets/scss/_variables.scss create mode 100644 assets/scss/main.scss create mode 100644 docs/SCSS_STYLING.md create mode 100644 openspec/changes/add-custom-bootstrap-styling/proposal.md create mode 100644 openspec/changes/add-custom-bootstrap-styling/specs/styling/spec.md create mode 100644 openspec/changes/add-custom-bootstrap-styling/tasks.md diff --git a/assets/scss/_custom.scss b/assets/scss/_custom.scss new file mode 100644 index 0000000..0abc164 --- /dev/null +++ b/assets/scss/_custom.scss @@ -0,0 +1,14 @@ +// Custom Component Styles +// Add custom styles that extend or modify Bootstrap components + +// Example: Custom navbar styling +// .navbar-brand { +// font-weight: 700; +// } + +// Example: Custom card styling +// .card { +// border-radius: 8px; +// } + +// Add your custom styles here diff --git a/assets/scss/_variables.scss b/assets/scss/_variables.scss new file mode 100644 index 0000000..454f055 --- /dev/null +++ b/assets/scss/_variables.scss @@ -0,0 +1,57 @@ +// Bootstrap Variable Overrides +// These variables override Bootstrap's default design tokens +// They are applied via CSS custom properties and utility classes + +// Typography - Base Font Size +// This is the root font size that Bootstrap uses for all rem calculations +// Default: 1rem (typically 16px in browsers) +$font-size-base: 1.25rem; + +// You can also set it to a specific pixel value: +// $font-size-base: 18px; // Makes everything slightly larger + +body { + font-size: $font-size-base; +} + +// Typography - Heading Font Sizes +// Customize heading sizes to establish visual hierarchy +$h1-font-size: 2rem; // Default: 2.5rem +$h2-font-size: 1.75rem; // Default: 2rem +$h3-font-size: 1.5rem; // Default: 1.75rem +$h4-font-size: 1.25rem; // Default: 1.5rem +$h5-font-size: 1rem; // Default: 1.25rem +$h6-font-size: 1rem; // Default: 1rem + +// Apply heading sizes using CSS +h1 { font-size: $h1-font-size; } +h2 { font-size: $h2-font-size; } +h3 { font-size: $h3-font-size; } +h4 { font-size: $h4-font-size; } +h5 { font-size: $h5-font-size; } +h6 { font-size: $h6-font-size; } + +// Link Colors +// Customize link colors for brand consistency +$link-color: #0b0089; // Default Bootstrap: #0d6efd +$link-hover-color: #0052a3; // Darker shade for hover state + +a { + color: $link-color; + + &:hover { + color: $link-hover-color; + } +} + +// Spacing +// Uncomment and customize spacing scale if needed +// $spacer: 1rem; +// $spacers: ( +// 0: 0, +// 1: $spacer * 0.25, +// 2: $spacer * 0.5, +// 3: $spacer, +// 4: $spacer * 1.5, +// 5: $spacer * 3, +// ); diff --git a/assets/scss/main.scss b/assets/scss/main.scss new file mode 100644 index 0000000..81e70a8 --- /dev/null +++ b/assets/scss/main.scss @@ -0,0 +1,8 @@ +// Main SCSS entry point for custom Bootstrap styling +// This file is processed by Hugo Pipes and loaded after Bootstrap CDN CSS + +// Import Bootstrap variable overrides +@import 'variables'; + +// Import custom component styles +@import 'custom'; diff --git a/docs/SCSS_STYLING.md b/docs/SCSS_STYLING.md new file mode 100644 index 0000000..a9aa931 --- /dev/null +++ b/docs/SCSS_STYLING.md @@ -0,0 +1,163 @@ +# 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.
