3.1.1 Language of Page
페이지 언어
Summary
The default language of the page must be declared programmatically. A single `<html lang="ko">` does it; without it a screen reader may apply the wrong pronunciation rules and render the text unintelligible. This is the cheapest accessibility fix there is.
Common failures
- A Korean page with no `lang` attribute, or one still set to `lang="en"`.
