Bilingual Layout Where One Column’s Language Goes Unmarked

3.1.2 — Language of Parts

Scenario

Setting

A customer-support live-chat widget

What’s wrong

Bilingual side-by-side layouts where one column is unmarked.

Example

Here's what happens on a customer-support live-chat widget: bilingual side-by-side layouts where one column is unmarked.

Why it matters

Screen-reader users hearing mixed-language content with the wrong voice rules. On a customer-support live-chat widget, this barrier means they can't tell what language they're reading.

How to test

Inspect a bilingual side-by-side layout: check whether both columns have correct lang attributes, or whether one column is left unmarked.

How to fix

The passage in another language must carry its own correct lang attribute.

Outcome

Corrected, a customer-support live-chat widget now lets a visitor understand which language they're reading.

Who is affected

Screen-reader users hearing mixed-language content with the wrong voice rules.
