A clean, academic LaTeX-style theme for Obsidian. Perfect for mathematical writing, technical documentation, and Chinese content.

Key Features

LaTeX-Identical Typography

Uses Latin Modern as the default font — the exact same typeface used in standard LaTeX documents. Additional options include:

  • Latin Modern — LaTeX default
  • Libertinus — Open-source math font
  • Times New Roman
  • SimSun (Chinese Song)

All fonts are embedded in CSS with no external dependencies — works perfectly offline.

Specialized Code Font

Code blocks use CMUNTT (Computer Modern Typewriter) — the exact same typewriter font used in LaTeX documents. For Chinese code comments, FandolFang (Chinese FangSong) is specially integrated to ensure elegant rendering of Chinese text within code.

Excellent Chinese Support

Specially designed for Chinese content:

  • FandolSong for body text
  • FandolFang for Chinese in code blocks
  • Robust fallback chain: SimSun → 宋体 → Noto Serif SC → Source Han Serif SC

LaTeX-Style Elements

Standard academic elements supported:

> [!theorem] Theorem content
> [!lemma] Lemma content
> [!definition] Definition content
> [!proof] Proof content
