Perceivable
Content and controls should remain available beyond a single color, image, scale or sensory cue.
THEION / ACCESSIBILITY / CONTINUOUS IMPROVEMENT
Clarity also means removing barriers.
THEION uses WCAG 2.2 Level AA as the technical target for this institutional website. That target guides implementation and verification; it is not presented as a formal certification already granted.
FOUR FOUNDATIONS
Accessibility must survive perception, operation, understanding and technology.
WCAG organizes accessibility around four principles. They provide the design direction; testable success criteria and human evaluation provide the evidence.
Operable
Navigation and controls should support keyboard use, visible focus and sufficient interaction targets.
Understandable
Language, headings, labels, navigation and changes of state should remain clear and predictable.
Robust
Structure, names, roles, values and status messages should remain interpretable by assistive technology.
IMPLEMENTED SUPPORTS
Concrete measures, stated without overstating conformance.
These measures are present in the site architecture and styles. Automated and source checks reduce defects, but they do not substitute for complete human and assistive-technology testing.
A1Structure and language
Pages identify their language, preserve a principal content landmark, use heading hierarchy and expose a skip path to the main content.
A2Keyboard and focus
Interactive elements use native controls or explicit semantics, visible focus treatment and labelled actions. Dialog behavior includes focus return and keyboard dismissal logic.
A3Contrast and legibility
The visual system uses responsive type, enlarged action areas and explicit high-contrast and forced-colors treatments. A complete route-by-route contrast audit remains a separate verification task.
A4Motion and transparency
Reduced-motion preferences disable non-essential animation, transitions and smooth scrolling. Reduced-transparency preferences remove blur from critical surfaces where supported.
A5Images and icons
Informative images receive alternative text. Decorative marks and icons are hidden from assistive reading so they do not create redundant noise.
A6Responsive and print views
Layouts reflow across compact and wide viewports, while article and legal print styles remove navigation that does not belong in the document.
VERIFICATION PATH
A conformance claim requires more than a successful build.
Formal evaluation must identify the tested scope, methods, environments, findings and remaining exceptions. It should be repeated when the product materially changes.
Representative routes
Select high-traffic, legal, editorial and interactive pages rather than testing only the home page.
Keyboard path
Complete navigation and interaction without a pointing device, including focus order, visibility and escape behavior.
Assistive reading
Evaluate headings, landmarks, names, roles, states and messages with representative screen-reader combinations.
Zoom and reflow
Inspect text scaling, compact viewports, orientation, contrast modes and system display preferences.
Record and retest
Track the page, environment, barrier, severity, correction and observed result before closing the finding.
REAL USE MATTERS
A technically valid control can still create a practical barrier.
Device, browser, input method, assistive technology, language and user objective all influence the actual experience.
Feedback becomes evidence when the context is preserved.
A useful report identifies the page, environment, intended task and observed barrier. THEION can then reproduce, prioritize, correct and retest the precise issue.
