Lx

Lx (repository: hexo-theme-lx) is a free, open-source Hexo blog theme designed to produce a simple, clear, and elegant blog, with built-in support for analytics, comments, local search, and MathJax rendering.

What is Lx?

Lx is a Hexo theme that turns a static blog project into a full-featured personal site. It takes standard Hexo Markdown posts and front-matter as input and renders them into a clean, responsive blog with configurable widgets, tags, and comment sections. The theme is developed by blleng and distributed on GitHub. It includes a stable demo at https://lx.js.org and a dev preview at https://lx.blleng.cn.

Key Features

• Analytics — supports both Google Analytics and Baidu Analytics; activate by adding your tracking ID to google_analytics or baidu_analytics in themes/lx/_config.yml.
• Local search — integrates with the hexo-generator-searchdb plugin; enable it by setting local_search.enable to true in the theme config.
• Valine comments — built-in comment system using Valine (requires a Leancloud app to supply appid and appkey); per-post toggle via the comment front-matter field.
• MathJax — supports mathematical formulas and chemical equations, with per-page activation via the mathjax: true front-matter option and a configurable CDN.
• Social links — configurable icon-and-link list using Font Awesome icons, defined in the social.links section of the theme config.
• Rich tag system — custom tags for notes, labels, buttons, centered quotations, and videos; for example {%note default%} renders styled admonition blocks and {%btn url,content,icon,title%} inserts buttons.
• Custom CSS — enable custom_css to load your own source/css/custom.styl file for styling overrides.
• Theme fonts — optional font settings with a configurable host and families, including separate control for code fonts like Fira Code.

Who is it for?

• Individual bloggers — who want a clean, no-frills Hexo theme to publish personal articles, with one-line setup for analytics and comments.
• Developers already using Hexo — who need a theme that integrates with the standard Hexo workflow, supports local search via hexo-generator-searchdb, and lets them tweak styles with Stylus custom CSS.
• Technical writers/students — who need MathJax support to display formulas and chemical equations in their posts by adding mathjax: true to the front-matter.

What can you do with Lx?

• Create a bilingual or personal blog — the README offers both English and Chinese docs, and posts are written in standard Markdown with front-matter tags, categories, and per-page options.
• Enable community discussion — turn on Valine comments per post or globally, letting readers leave messages without a third-party hosted comment service beyond Leancloud.
• Add structured media — use the video tag {% video url %} to embed videos and the center-quote tag {%cq%} to highlight quotations, all through simple shortcodes.
• Track visitor behavior — plug in Google or Baidu analytics IDs in the config file to collect page-view data without editing templates.

How does Lx work?

Lx works like any standard Hexo theme: you install it by cloning the themes/lx folder into your Hexo site's themes directory, then set theme: lx in the site's _config.yml. After that, you write posts in Markdown, optionally enabling comment, MathJax, or other per-page features in each post's front-matter, and run your normal Hexo generate command to build the static site.

Pricing

Lx is free and open source. The GitHub repository shows a license file, and there are no mentioned paid tiers, subscriptions, or premium features.
