Missing document language in Shopify
WCAG 3.1.1 (A) · EN 301 549 9.3.1.1
The <html> element declares no valid language.
Where to change it in Shopify
In layout/theme.liquid, the first line should be <html lang="{{ request.locale.iso_code }}">.
Shopify themes are edited under Online Store › Themes. "Edit code" opens the Liquid templates. Many colour and typography settings can be changed without coding, from the theme editor.
<html><html lang="en">Why it matters
Screen readers pick the voice and pronunciation from that attribute. Without it, a Spanish shop can be read with English phonetics, and nothing is intelligible.
