The Art of Typography
Good typography is invisible — it lets readers focus on content, not formatting. The right combination of font, size, and spacing creates a seamless reading experience.
优秀的排版是无形的——它让读者专注于内容而非格式。字体、字号和间距的恰当组合，能够创造出流畅的阅读体验。
VMark supports mixed CJK and Latin text with automatic spacing. Whether you write in English, 中文, 日本語, or 한국어 — typography just works.

Focus Mode
Click any paragraph to focus on it
Focus Mode helps you concentrate on what matters most — the current paragraph you're writing.
When enabled, VMark dims surrounding content while keeping your current paragraph fully visible and vibrant.
This creates a natural visual hierarchy that reduces distractions and keeps your attention where it belongs.
Combined with Typewriter Mode, your cursor stays centered on screen for a comfortable writing flow.
💡In VMark, focus automatically follows your cursor as you type.
