|
### Dropdown Menu Support in Navbar
|
|
|
|
Create dropdown menus in your navigation bar for better navigation items organization.
|
|
|
|
```yaml {filename="hugo.yaml"}
|
|
menu:
|
|
main:
|
|
- identifier: products
|
|
name: "Products"
|
|
- name: "Product A"
|
|
parent: products
|
|
url: "/product-a"
|
|
- name: "Product B"
|
|
parent: products
|
|
url: "/product-b"
|
|
```
|
|
|
|
|
|
|
|
### Enhanced Search Experience
|
|
|
|
- **Search in all headings**: find content across all heading levels, not just page titles
|
|
- **Improved result accuracy**: better title handling and linking precision
|
|
- **Fixed result navigation**: search results now link to the correct page sections
|
|
|
|
Huge thanks to [@ldez](https://github.com/ldez) for pushing the search capabilities forward!
|
|
|
|
|
|
|
|
### llms.txt Support
|
|
|
|
Hextra now supports [llms.txt](https://llmstxt.org/) output format for your site, making your site more accessible to AI tools and language models for context and reference.
|
|
|
|
```yaml {filename="hugo.yaml"}
|
|
outputs:
|
|
home: [html, llms]
|
|
```
|
|
|
|
This will generate an `llms.txt` file at your site's root.
|
|
|
|
|
|
|
|
### Table of Contents Scroll Highlighting
|
|
|
|
The table of contents now automatically highlights the current section as you scroll through the page, making navigation more intuitive.
|
|
|
|
|
|
|
|
### Synchronized Tab Switching
|
|
|
|
Tabs with the same items now synchronize across the page. When sync is enabled, selecting a tab updates all tab groups that share the same items list (and your selection is remembered).
|
|
|
|
```yaml {filename="hugo.yaml"}
|
|
params:
|
|
page:
|
|
tabs:
|
|
sync: true
|
|
```
|
|
|
|
### Blog List Pagination
|
|
|
|
Basic pagination controls have been added to blog listing pages.
|
|
|
|
```yaml {filename="hugo.yaml"}
|
|
params:
|
|
blog:
|
|
list:
|
|
pagerSize: 20 # Posts per page
|
|
```
|
|
|
|
|
|
|
|
### MathJax Support
|
|
|
|
Render mathematical expressions with [MathJax](https://www.mathjax.org/) alongside the default KaTeX support. Choose the engine that best fits your needs.
|
|
|
|
```yaml {filename="hugo.yaml"}
|
|
params:
|
|
math:
|
|
engine: "mathjax" # default is "katex"
|
|
```
|
|
|
|
## Technical Improvements
|
|
|
|
### Framework and Build System
|
|
|
|
- **Tailwind CSS v4 Migration**: complete migration to [Tailwind CSS v4](https://tailwindcss.com/blog/tailwindcss-v4) with improved customization support.
|
|
- **Hugo Template System**: adapted to Hugo's [new template system](https://gohugo.io/templates/new-templatesystem-overview/) (v0.146.0+) for future compatibility.
|
|
- **Math Server-Side Rendering**: better handling of math equation rendering using Hugo native rendering by default.
|
|
- **FlexSearch 0.8 Upgrade**: upgraded search engine [FlexSearch](https://github.com/nextapps-de/flexsearch) for faster, more accurate results with improved CJK (Chinese, Japanese, Korean) content encoding.
|
|

|
|
|
|
## Quality of Life Improvements

|

|
## Bug Fixes and Stability

|
|
- **Search result accuracy**: fixed linking issues and title escaping in search results
|
|
- **Tab switching**: resolved navigation issues in non-synced tab mode
|
|

## Migration Guide
|
|
|
|
- [**Hugo Version Requirements**](#hugo-version-requirements): Requires Hugo v0.146.0+ (extended version)
|
|
- [**CSS Class Prefix Changes**](#css-class-prefix-changes): Component CSS classes now use consistent `hextra-` prefixing
|
|
- [**Asset Management**](#asset-management-for-katex-and-mermaid): KaTeX and Mermaid assets now download during build time
|
|
- [**Tailwind CSS v4**](#tailwind-css-v4): Internal CSS compilation now uses Tailwind CSS v4.x with `hx:` prefix
|
|
|
|
#### Hugo Version Requirements
|
|
|
|
**Impact**: Sites running older Hugo versions
|
|
|
|
Hextra v0.10.0 requires Hugo v0.146.0 or later (extended version) due to the new template system adoption.
|
|
|
|
**Action required**: Update Hugo to v0.146.0+ before upgrading Hextra
|
|
|
|
#### CSS Class Prefix Changes
|
|
|
|
**Impact**: Sites with custom CSS targeting Hextra component classes
|
|
|
|
Hextra v0.10.0 introduces consistent `hextra-` prefixing for majority of component CSS classes to improve maintainability and prevent conflicts with user styles.
|
|
|
|
**Action required**: If you have custom CSS targeting Hextra components, update the following class names:
|
|
|
|
| Area | Before | After |
|
|
| -------------------- | ---------------------------- | ------------------------------------------------- |
|
|
| Search (container) | `.search-wrapper` | `.hextra-search-wrapper` |
|
|
| Search (input) | `.search-input` | `.hextra-search-input` |
|
|
| Search (results) | `.search-results` | `.hextra-search-results` |
|
|
| Search (title) | `.search-wrapper .title` | `.hextra-search-wrapper .hextra-search-title` |
|
|
| Search (active item) | `.search-wrapper .active` | `.hextra-search-wrapper .hextra-search-active` |
|
|
| Search (no result) | `.search-wrapper .no-result` | `.hextra-search-wrapper .hextra-search-no-result` |
|
|
| Search (prefix) | `.search-wrapper .prefix` | `.hextra-search-wrapper .hextra-search-prefix` |
|
|
| Search (excerpt) | `.search-wrapper .excerpt` | `.hextra-search-wrapper .hextra-search-excerpt` |
|
|
| Search (match) | `.search-wrapper .match` | `.hextra-search-wrapper .hextra-search-match` |
|
|
| Navbar blur | `.nav-container-blur` | `.hextra-nav-container-blur` |
|
|
| Hamburger menu | `.hamburger-menu` | `.hextra-hamburger-menu` |
|
|
| Theme toggle | `.theme-toggle` | `.hextra-theme-toggle` |
|
|
| Language switcher | `.language-switcher` | `.hextra-language-switcher` |
|
|
| Sidebar container | `.sidebar-container` | `.hextra-sidebar-container` |
|
|
| Sidebar active item | `.sidebar-active-item` | `.hextra-sidebar-active-item` |
|
|
| Code filename | `.filename` | `.hextra-code-filename` |
|
|
| Copy icon | `.copy-icon` | `.hextra-copy-icon` |
|
|
| Success icon | `.success-icon` | `.hextra-success-icon` |
|
|
| Steps | `.steps` | `.hextra-steps` |
|
|
|
|
#### Asset Management for KaTeX and Mermaid
|
|
|
|
**Impact**: Sites using KaTeX or Mermaid
|
|
|
|
Hextra v0.10.0 now downloads KaTeX and Mermaid assets from CDN during build time.
|
|
|
|
**What's changed:**
|
|
|
|
- Build process now requires internet access to download these assets
|
|
- No more external CDN calls for these assets after build
|
|
|
|
**Action required**:
|
|
|
|
- Ensure your build environment has internet access to download assets
|
|
- Sites in air-gapped environments may need to pre-download these assets and configure Hextra to load them
|
|
|
|
#### Tailwind CSS v4
|
|
|
|
**Impact**: Sites with extensive custom CSS targeting Hextra Tailwind classes `hx-*`
|
|
|
|
While Hextra handles the Tailwind CSS v4 migration internally, sites with heavy customizations may need further adjustments.
|
|
|
|
**What's changed:**
|
|
|
|
- Internal CSS compilation now uses Tailwind CSS v4.x
|
|
- Utility classes now prefix with `hx:` rather than `hx-`
