What the standard specifies
WCAG 2.2 includes success criteria addressing visible focus, focus not being obscured, and minimum target size, subject to the standard’s stated exceptions. These criteria help teams discuss specific interaction behavior rather than accessibility as a vague aspiration.
W3C’s specification applies to web content. A CMS interface may have additional platform and organizational considerations, so teams should assess the actual authoring environment and applicable standards rather than assume a checklist establishes conformance.
Test the authoring journey
In Custom CMS Creation prototypes, follow an editor through adding a content block, opening a preview, selecting a date, and publishing. Check focus visibility, dialog behavior, control spacing, and whether the interface reveals the current action and state.
These tests can expose design decisions while they are still cheap to change. Increasing a click target or improving focus treatment in a prototype is simpler than retrofitting a dense editor after authors have been trained on it.
Make findings operational
Translate a finding into a reproducible task: identify the component, input method, expected behavior, and affected role. Re-test the fix in the real interface and review whether the change improves the whole flow rather than a single screenshot.
W3C provides a concrete reference; agency interpretation turns it into design and QA work. CMS accessibility also depends on published content, so an accessible editor should guide good choices without implying that every resulting page is automatically accessible.
