WCAG 1.3.1 Info and Relationships Level A
Who this affects
Some content sits outside any landmark, so it is missed when navigating by region.
How to fix it
Place all content inside landmarks: <header>, <nav>, <main>, <aside>, <footer>.
How much work is it?
Usually a template or design change. That is a rough guide for planning, not an estimate for your codebase. A single content edit repeated across a template is a template change.
What a person still has to check
Passing this rule does not mean 1.3.1 passes. Automation checks part of the criterion, and the rest is a judgement:
Confirm headings, lists, and tables are marked up as such, and that visual grouping is reflected in the markup.

Where this check comes from
This is an axe-core rule. We run axe in a real browser on every page we scan. Deque’s reference for region
Find out whether your site does this
A scan checks this rule on every page it visits, and shows you the code and a screenshot of each place it fires.
