Purpose

What this test checks

Checks zoomed dialogs, sticky content and focus using real browser or operating-system controls.

What this result means: This procedure records how Zoomed dialogs, sticky content and focus behaves on desktop-zoom-reflow. It can expose evidence relevant to WCAG 1.4.10, 2.4.7 and 2.4.11 for the tested task and environment. Use the linked conformance procedures for WCAG 1.4.10, 2.4.7 and 2.4.11 to assess the complete requirements across the declared conformance scope.

Why it matters

Checks zoomed dialogs, sticky content and focus using real browser or operating-system controls. People most likely affected: people with low vision who enlarge text or content and people who use narrow viewports. Content, controls, focus or validation may be clipped, overlap or require avoidable two-dimensional scrolling. In the recorded desktop-zoom-reflow environment, inspect navigation, dialogs, validation, sticky regions and horizontal movement at the required magnification; clipped or overlapping content can remove both information and operable controls.

When to use it

Apply Zoomed dialogs, sticky content and focus when the frozen page or document presentation at the genuine zoom, viewport and text settings named by the procedure. The selected focus is Zoomed dialogs, sticky content and focus.

Confirm before starting

Mark it not applicable only when

Exceptions

This platform, journey, usability or quality procedure creates no additional normative exception. Apply exceptions only in the linked atomic or criterion-level conformance procedure and preserve that separate decision.

Prepare

What you need

  • The product area and test targets are agreed before testing starts.
  • The operating system, browser, viewport and input method are recorded.
  • Test data is safe to use and does not expose unnecessary personal information.

Targets and required variations

  • Each selected page, component and state relevant to Zoomed dialogs, sticky content and focus.
  • Default, revealed, loading, empty, validation error, interruption, recovery and confirmation where meaningful.
  • Every required environment, viewport, orientation, language and authenticated state recorded in the frozen scope.

Clean state

  • Complete a known-good calibration in the same environment before product testing.
  • Start from a recorded clean or known state and preserve any prior preferences, extensions, cache or profile settings that can affect output.

Assumptions: one responsive page at the required zoom or viewport settings; repeat for fixed regions and breakpoint-specific layouts

Variation: Add a new per-target execution and evidence allowance for each additional target class or state that could produce a different result. Add setup time for each distinct environment.

Excluded: Client coordination, inaccessible-environment recovery, recruitment, legal review, remediation implementation and waiting time unless the procedure states otherwise.

Execute

Test steps

Follow each action in order. The expected result is always visible; open the guidance when you need setup, tool, evidence, decision or repeat details. Step-level recording is optional while work is in progress and required only to export a completed execution.

Step 1

Prepare the scope, target and environment

Purpose: For Zoomed dialogs, sticky content and focus, prepare the named scenario: Prepare the scope, target and environment. Target: Each selected page, component and state relevant to Zoomed dialogs, sticky content and focus. The preparation must establish this result: The selected targets, states, test data, environment and any scope limitations are complete enough for another qualified tester to reproduce the setup.

User impact: Content, controls, focus or validation may be clipped, overlap or require avoidable two-dimensional scrolling. This scenario isolates that risk in the action named Prepare the scope, target and environment.

Before executing Zoomed dialogs, sticky content and focus, freeze the product version and scope. Inventory each applicable target, select the required starting states, prepare safe test data and record every required environment value. Complete any named known-good calibration before attributing an observation to the product.

Expected result

The selected targets, states, test data, environment and any scope limitations are complete enough for another qualified tester to reproduce the setup.

Failure observation

During Zoomed dialogs, sticky content and focus, the target, starting state, environment or scope record remains ambiguous for the scenario named Prepare the scope, target and environment. The preparation result cannot be demonstrated: The selected targets, states, test data, environment and any scope limitations are complete enough for another qualified tester to reproduce the setup.

Setup, evidence and decision guidance
Target
Each selected page, component and state relevant to Zoomed dialogs, sticky content and focus.
Required state
For Zoomed dialogs, sticky content and focus, the product version and scope are frozen; every selected target and material starting state is uniquely identified.
Tool or command
Use the scope record and worksheet environment fields for Zoomed dialogs, sticky content and focus: operating_system, operating_system_version, browser, browser_version, viewport_css_pixels, input_method, zoom_level.
Record
Scope/version reference; target inventory; starting states; safe-data reference; every required environment value; calibration result or reason it is not required.
Pass
Record passed for the Zoomed dialogs, sticky content and focus scenario named Prepare the scope, target and environment only when the evidence (Scope/version reference; target inventory; starting states; safe-data reference; every required environment value; calibration result or reason it is not required.) supports: The selected targets, states, test data, environment and any scope limitations are complete enough for another qualified tester to reproduce the setup.
Fail
Record failed when the action is completed and this failure observation is reproduced: During Zoomed dialogs, sticky content and focus, the target, starting state, environment or scope record remains ambiguous for the scenario named Prepare the scope, target and environment. The preparation result cannot be demonstrated: The selected targets, states, test data, environment and any scope limitations are complete enough for another qualified tester to reproduce the setup.
Not applicable
The frozen scope contains no content or state to which Zoomed dialogs, sticky content and focus can be applied.
Blocked
Record blocked, not passed, when An applicable target, required state, complete process or named real environment was not executed.
Repeat or recover
For Zoomed dialogs, sticky content and focus, correct the setup gap, preserve the original blocked record and start a new execution observation before proceeding.
Limitations
This scenario records the action named Prepare the scope, target and environment for Zoomed dialogs, sticky content and focus in desktop-zoom-reflow. It does not establish behaviour for another target, state or environment and does not set a WCAG conformance decision.
If you are new to this test
For Zoomed dialogs, sticky content and focus, do not begin from an undocumented browser tab, document copy, device state, participant plan or evidence set. Record the exact item you will test first.
Record this step

Step 2

At 400%, open dialogs, drawers, cookie notices and sticky navigation

Purpose: For Zoomed dialogs, sticky content and focus, execute the named scenario: At 400%, open dialogs, drawers, cookie notices and sticky navigation. Target: Each selected page, component and state relevant to Zoomed dialogs, sticky content and focus. Compare the observation with this result: Dialog content reflows, controls remain reachable and focus is visible and not entirely obscured.

User impact: Content, controls, focus or validation may be clipped, overlap or require avoidable two-dimensional scrolling. This scenario isolates that risk in the action named At 400%, open dialogs, drawers, cookie notices and sticky navigation.

At 400%, open dialogs, drawers, cookie notices and sticky navigation; traverse every control and monitor focused-element visibility.

Expected result

Dialog content reflows, controls remain reachable and focus is visible and not entirely obscured.

Failure observation

After the tester completes the Zoomed dialogs, sticky content and focus scenario named At 400%, open dialogs, drawers, cookie notices and sticky navigation, the recorded observation for the target is inconsistent with the required result: Dialog content reflows, controls remain reachable and focus is visible and not entirely obscured.

Setup, evidence and decision guidance
Target
Each selected page, component and state relevant to Zoomed dialogs, sticky content and focus.
Required state
For Zoomed dialogs, sticky content and focus, begin in keyboard focus on the last confirmed target before the action, with no pointer assistance; preserve the exact content, account, platform and configuration used.
Tool or command
In desktop-zoom-reflow, Use the browser's genuine zoom control and measure the resulting CSS-pixel viewport; use text-only zoom only when the action explicitly asks for it. Developer-tool emulation may diagnose a defect but is not execution evidence.
Record
Viewport and full-page evidence for default, revealed, validation, sticky and dialog states. Capture full-page and viewport evidence at the actual zoom level, including any exempt two-dimensional region and its justification.
Pass
Record passed for the Zoomed dialogs, sticky content and focus scenario named At 400%, open dialogs, drawers, cookie notices and sticky navigation only when the evidence (Viewport and full-page evidence for default, revealed, validation, sticky and dialog states. Capture full-page and viewport evidence at the actual zoom level, including any exempt two-dimensional region and its justification.) supports: Dialog content reflows, controls remain reachable and focus is visible and not entirely obscured.
Fail
Record failed when the action is completed and this failure observation is reproduced: After the tester completes the Zoomed dialogs, sticky content and focus scenario named At 400%, open dialogs, drawers, cookie notices and sticky navigation, the recorded observation for the target is inconsistent with the required result: Dialog content reflows, controls remain reachable and focus is visible and not entirely obscured.
Not applicable
The frozen scope contains no content or state to which Zoomed dialogs, sticky content and focus can be applied.
Blocked
Record blocked, not passed, when An applicable target, required state, complete process or named real environment was not executed.
Repeat or recover
Repeat on each representative template and in opened menus, dialogs, errors, sticky regions and other states that can change layout. Preserve the first Zoomed dialogs, sticky content and focus observation when repeating.
Limitations
This scenario records the action named At 400%, open dialogs, drawers, cookie notices and sticky navigation for Zoomed dialogs, sticky content and focus in desktop-zoom-reflow. It does not establish behaviour for another target, state or environment and does not set a WCAG conformance decision.
If you are new to this test
For Zoomed dialogs, sticky content and focus: Record the starting viewport, browser zoom, operating-system scale and resulting CSS viewport before judging clipping or two-dimensional scrolling.
Record this step

Step 3

Inspect top, middle and end of every representative page and complete critical success, error and recovery journeys using keyboard and pointer

Purpose: For Zoomed dialogs, sticky content and focus, execute the named scenario: Inspect top, middle and end of every representative page and complete critical success, error and recovery journeys using keyboard and pointer. Target: Each selected page, component and state relevant to Zoomed dialogs, sticky content and focus. Compare the observation with this result: No off-screen, clipped or unreachable content is missed by a static screenshot.

User impact: Content, controls, focus or validation may be clipped, overlap or require avoidable two-dimensional scrolling. This scenario isolates that risk in the action named Inspect top, middle and end of every representative page and complete critical success, error and recovery journeys using keyboard and pointer.

Inspect top, middle and end of every representative page and complete critical success, error and recovery journeys using keyboard and pointer.

Expected result

No off-screen, clipped or unreachable content is missed by a static screenshot.

Failure observation

After the tester completes the Zoomed dialogs, sticky content and focus scenario named Inspect top, middle and end of every representative page and complete critical success, error and recovery journeys using keyboard and pointer, the recorded observation for the target is inconsistent with the required result: No off-screen, clipped or unreachable content is missed by a static screenshot.

Setup, evidence and decision guidance

Decide

How to decide

Passed

Dialog content reflows, controls remain reachable and focus is visible and not entirely obscured.

Failed

An applicable Zoomed dialogs, sticky content and focus target has a reproducible material barrier against one or more stated expectations; identify the exact expectation, state and evidence.

Not applicable
The frozen scope contains no content or state to which Zoomed dialogs, sticky content and focus can be applied.
Cannot tell
The target is applicable, but conflicting evidence or unresolved responsibility prevents a defensible expectation decision after recorded comparison.
Not tested
An applicable target, required state, complete process or named real environment was not executed.
Aggregation and reporting boundaries

Aggregation: Preserve every target/environment outcome. Any failed target prevents an overall passed procedure result. cantTell and untested remain unresolved; inapplicable is valid only when the completed inventory contains no applicable target.

WCAG decision: This specialist, platform, document, usability or quality result does not set a WCAG success criterion to satisfied or not_satisfied automatically. Use linked atomic and criterion-level procedures for that separate decision.

Automation: A checker, accessibility-tree inspection, emulator or simulated assistive technology is diagnostic evidence only. Complete every required manual, real-platform, contextual and exception check.

Worked example and outcome calibration

A11Y-ZOOM-005-WORKED-001: representative worked example

Context: Representative synthetic example for Zoomed dialogs, sticky content and focus on a fictional, version-frozen product target; no client or participant execution occurred.

Inspected: The tester follows S2 (At 400%, open dialogs, drawers, cookie notices and sticky navigation) using the target, required state, tool and repeat rule stated in this procedure.

Observed output: After the tester completes the Zoomed dialogs, sticky content and focus scenario named At 400%, open dialogs, drawers, cookie notices and sticky navigation, the recorded observation for the target is inconsistent with the required result: Dialog content reflows, controls remain reachable and focus is visible and not entirely obscured.

Evidence:

  • example-evidence-001: target and state record for Each selected page, component and state relevant to Zoomed dialogs, sticky content and focus.
  • example-evidence-002: contemporaneous observation from the named method — Viewport and full-page evidence for default, revealed, validation, sticky and dialog states. Capture full-page and viewport evidence at the actual zoom level, including any exempt two-dimensional region and its justification.
  • example-evidence-003: comparison note linking the actual observation to the expected result and claim boundary

Tester reasoning: The recorded observation does not demonstrate the expected result: Dialog content reflows, controls remain reachable and focus is visible and not entirely obscured. The failed decision is limited to this synthetic target and state; unexecuted coverage is not inferred.

Decision: failed

Finding: A11Y-ZOOM-005-example-finding-001 — Zoomed dialogs, sticky content and focus: expected result is not demonstrated. The represented barrier may affect People with low vision who enlarge text or content and people who use narrow viewports.

Remediation: Change the represented target or process so it demonstrates this result: Dialog content reflows, controls remain reachable and focus is visible and not entirely obscured. Then rerun the affected step and every dependent variation.

Reviewer feedback: The reviewer confirms applicability, environment, actual-versus-expected comparison, evidence references and bounded wording; unsupported product-wide or conformance language is removed.

Final client wording: Synthetic training finding: the sampled Zoomed dialogs, sticky content and focus target does not meet the procedure expectation in the recorded state. User impact and broader scope require evidence from the buyer's real execution.

Retest: Synthetic retest example: after the represented change, repeat the failed step plus material error and recovery states. Close the finding only when new evidence demonstrates the expected result; otherwise retain the non-pass outcome.

Boundary: This is a representative, synthetic worked example for training and calibration. It is not evidence from a client product, participant or real assistive-technology execution.

Outcome calibration

Passed
In desktop-zoom-reflow, the selected Zoomed dialogs, sticky content and focus target completes the recorded action and meets this expectation: Dialog content reflows, controls remain reachable and focus is visible and not entirely obscured.

The example is a calibration scenario, not an execution or approval.

Failed
An applicable Zoomed dialogs, sticky content and focus target produces a reproducible barrier during the named action, with the exact state and affected user task recorded.

A failed target remains failed even if another environment or target passes.

Not applicable
The frozen scope contains no content or state to which Zoomed dialogs, sticky content and focus can be applied.

Inapplicable requires a completed inventory showing that no target matches applicability; a missing environment is not inapplicable.

Cannot tell
The Zoomed dialogs, sticky content and focus target is applicable, but conflicting product/platform evidence or missing authoritative information prevents a defensible responsibility or expectation decision.

Record the conflict, comparisons attempted and person or evidence needed to resolve it.

Not tested
The Zoomed dialogs, sticky content and focus target is applicable, but a required state, complete process or real environment was not executed.

Untested remains incomplete and cannot be converted to passed or inapplicable.

Sampling, complete processes and platform limitations

Test every in-scope instance when practical. For a large population, document a sample that includes each template, content or control type, meaningful state and high-risk task.

If this check is part of a user journey, test the selected journey from start to finish, including relevant errors and recovery. Record any path that was not tested.

  • Emulation can support diagnosis but does not replace the genuine browser or operating-system presentation required by the procedure.
  • Check relevant browser, tool or assistive-technology release notes before assigning unexpected behaviour to the product.
  • If responsibility is unclear, record the reproducible behaviour and use cannot tell until it is resolved.
