feat(theme-classic): add text-autospace for improved CJK readability by fffzzau · Pull Request #11933 · facebook/docusaurus

fffzzau · 2026-04-12T04:02:52Z

This PR introduces the text-autospace CSS property to the global layout which has the issue #11928 . Currently, when Latin characters (English, numbers) are placed immediately next to CJK (Chinese, Japanese, Korean) characters, the lack of spacing can make the text feel cramped and reduce readability.

I hereby setting text-autospace: normal, the browser automatically injects a small amount of visual "breathing room" between these different script types, following standard typographic principles for multi-script documents. I have also disabled this for code-related elements (pre, code, etc.) to ensure technical strings remain precise.

Test Plan
I verified this change by running the Docusaurus development server locally and inspecting the rendering of mixed-script strings.

Manual Inspection:
Used the browser developer tools to toggle the text-autospace property on and off.

Visual Confirmation:
Verified that strings like 5分 and curlを使用 show the correct typographic spacing when the property is active.
