Purpose

What this test checks

Author-created content entirely hides the component receiving keyboard focus.

What this result means: This WCAG 2.4.11 Focus Not Obscured (Minimum) procedure determines whether the recorded targets meet WCAG 2.4.11 on web-desktop-cross-browser in the tested states. A broader conformance decision must also account for every applicable target in the declared scope, complete processes, accessibility-supported use and the other WCAG conformance requirements.

Why it matters

Author-created content entirely hides the component receiving keyboard focus. People most likely affected: people who use keyboards, switches, speech input or adapted pointing devices; People with low vision or reduced contrast sensitivity. Users may not see or operate the focused control. In the recorded web-desktop-cross-browser environment, apply the criterion to every relevant state and named normative exception; failures in critical tasks and complete processes carry the greatest user impact.

When to use it

Evaluate initial positions of user-movable content; user-opened content may cover focus if it can be revealed without advancing focus.

Confirm before starting

Mark it not applicable only when

Exceptions

User-movable content positions

Decision condition
For configurable user-movable content, only initial positions are considered.
Evidence needed
Initial configuration and user movement evidence.
Common error
Author-set responsive positions are not user-moved positions.
Scope
Only the user-movable content position.

User-opened content with reveal

Decision condition
User-opened content obscures focus, but the focused component can be revealed without advancing keyboard focus.
Evidence needed
Opening action and keyboard reveal action/result.
Common error
Requiring focus to move does not qualify.
Scope
Only that obscuring content/state.

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 component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present.
  • Default and every meaningful state or variation that can change the result.

Clean state

  • Start from a documented clean or known state and record pre-existing preferences, extensions and cached data that can change the result.

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

Inventory applicable targets

Purpose: For WCAG 2.4.11 Focus Not Obscured (Minimum), prepare the named scenario: Inventory applicable targets. Target: Each component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present. The preparation must establish this result: Every selected target and state is uniquely identifiable before testing.

User impact: Users may not see or operate the focused control. This scenario isolates that risk in the action named Inventory applicable targets.

Freeze the page, content and product version. Inventory Each component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present. Apply this rule: Evaluate initial positions of user-movable content; user-opened content may cover focus if it can be revealed without advancing focus.

Expected result

Every selected target and state is uniquely identifiable before testing.

Failure observation

During WCAG 2.4.11 Focus Not Obscured (Minimum), the target, starting state, environment or scope record remains ambiguous for the scenario named Inventory applicable targets. The preparation result cannot be demonstrated: Every selected target and state is uniquely identifiable before testing.

Setup, evidence and decision guidance
Target
Each component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present.
Required state
For WCAG 2.4.11 Keep focused components from being entirely hidden, use default and every meaningful state or variation that can change the result.
Tool or command
For WCAG 2.4.11, use the frozen scope inventory, product requirements and rendered content to identify every Keep focused components from being entirely hidden target.
Record
Page/view, target identifier, state, technology, sample rationale and scope limitation.
Pass
Record passed for the WCAG 2.4.11 Focus Not Obscured (Minimum) scenario named Inventory applicable targets only when the evidence (Page/view, target identifier, state, technology, sample rationale and scope limitation.) supports: Every selected target and state is uniquely identifiable before testing.
Fail
Record failed when the action is completed and this failure observation is reproduced: During WCAG 2.4.11 Focus Not Obscured (Minimum), the target, starting state, environment or scope record remains ambiguous for the scenario named Inventory applicable targets. The preparation result cannot be demonstrated: Every selected target and state is uniquely identifiable before testing.
Not applicable
The completed scope inventory contains no target matching: Each component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present.
Blocked
Record blocked, not passed, when The target is applicable, but a required action, state, environment or evidence item was not completed.
Repeat or recover
Repeat the WCAG 2.4.11 target inventory after a material content, state, technology or process change.
Limitations
This WCAG 2.4.11 Focus Not Obscured (Minimum) scenario covers only the action named Inventory applicable targets for the recorded target and state. It contributes evidence to 2.4.11; apply the procedure's aggregation, complete-process and conformance-scope rules before making a broader decision.
If you are new to this test
For WCAG 2.4.11, keep agreed scope exclusions separate from the target's applicable, inapplicable and pass outcomes.
Record this step

Step 2

Keep focused components from being entirely hidden

Purpose: For WCAG 2.4.11 Focus Not Obscured (Minimum), execute the named scenario: Keep focused components from being entirely hidden. Target: Each component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present. Compare the observation with this result: The component receiving keyboard focus is not entirely hidden by author-created content.

User impact: Users may not see or operate the focused control. This scenario isolates that risk in the action named Keep focused components from being entirely hidden.

Move focus through pages with sticky headers, cookie notices, drawers, dialogs and virtual keyboards at default and zoomed views.

Expected result

The component receiving keyboard focus is not entirely hidden by author-created content.

Failure observation

After the tester completes the WCAG 2.4.11 Focus Not Obscured (Minimum) scenario named Keep focused components from being entirely hidden, the recorded observation for the target is inconsistent with the required result: The component receiving keyboard focus is not entirely hidden by author-created content.

Setup, evidence and decision guidance
Target
Each component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present.
Required state
For WCAG 2.4.11 Keep focused components from being entirely hidden, use default and every meaningful state or variation that can change the result.
Tool or command
Keyboard traversal at selected viewports/zoom with screenshots and overlay geometry.
Record
Focused component, overlay, viewport, focus sequence, visibility and reveal action where applicable.
Pass
Record passed for the WCAG 2.4.11 Focus Not Obscured (Minimum) scenario named Keep focused components from being entirely hidden only when the evidence (Focused component, overlay, viewport, focus sequence, visibility and reveal action where applicable.) supports: The component receiving keyboard focus is not entirely hidden by author-created content.
Fail
Record failed when the action is completed and this failure observation is reproduced: After the tester completes the WCAG 2.4.11 Focus Not Obscured (Minimum) scenario named Keep focused components from being entirely hidden, the recorded observation for the target is inconsistent with the required result: The component receiving keyboard focus is not entirely hidden by author-created content.
Not applicable
The completed scope inventory contains no target matching: Each component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present.
Blocked
Record blocked, not passed, when The target is applicable, but a required action, state, environment or evidence item was not completed.
Repeat or recover
Repeat the WCAG 2.4.11 action when the target's content, state, environment or underlying technology changes.
Limitations
This WCAG 2.4.11 Focus Not Obscured (Minimum) scenario covers only the action named Keep focused components from being entirely hidden for the recorded target and state. It contributes evidence to 2.4.11; apply the procedure's aggregation, complete-process and conformance-scope rules before making a broader decision.
If you are new to this test
For WCAG 2.4.11 Keep focused components from being entirely hidden, record the actual evidence before deciding; use checker or visual evidence alone only when this procedure defines it as the measurement.
Record this step

Step 3

Repeat material variations and recovery

Purpose: For WCAG 2.4.11 Focus Not Obscured (Minimum), execute the named scenario: Repeat material variations and recovery. Target: Each component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present. Compare the observation with this result: Every material variation and required recovery path has its own reproducible observation; no unexecuted state is merged into a passing result.

User impact: Users may not see or operate the focused control. This scenario isolates that risk in the action named Repeat material variations and recovery.

Repeat the WCAG 2.4.11 Focus Not Obscured (Minimum) action for each inventoried variation that can change the outcome. Include relevant default, revealed, error, interruption, recovery and confirmation states and complete the selected process from start to finish where this test can affect task completion.

Expected result

Every material variation and required recovery path has its own reproducible observation; no unexecuted state is merged into a passing result.

Failure observation

After the tester completes the WCAG 2.4.11 Focus Not Obscured (Minimum) scenario named Repeat material variations and recovery, the recorded observation for the target is inconsistent with the required result: Every material variation and required recovery path has its own reproducible observation; no unexecuted state is merged into a passing result.

Setup, evidence and decision guidance
Target
Each component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present.
Required state
For WCAG 2.4.11 Focus Not Obscured (Minimum): Default and every meaningful state or variation that can change the result.
Tool or command
For WCAG 2.4.11 Focus Not Obscured (Minimum), use the same recorded method, then change only the state, environment or recovery condition being compared.
Record
Variation identifier; changed state or environment; start and end points; actual observation; recovery result; intervention; evidence reference and target outcome.
Pass
Record passed for the WCAG 2.4.11 Focus Not Obscured (Minimum) scenario named Repeat material variations and recovery only when the evidence (Variation identifier; changed state or environment; start and end points; actual observation; recovery result; intervention; evidence reference and target outcome.) supports: Every material variation and required recovery path has its own reproducible observation; no unexecuted state is merged into a passing result.
Fail
Record failed when the action is completed and this failure observation is reproduced: After the tester completes the WCAG 2.4.11 Focus Not Obscured (Minimum) scenario named Repeat material variations and recovery, the recorded observation for the target is inconsistent with the required result: Every material variation and required recovery path has its own reproducible observation; no unexecuted state is merged into a passing result.
Not applicable
The completed scope inventory contains no target matching: Each component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present.
Blocked
Record blocked, not passed, when The target is applicable, but a required action, state, environment or evidence item was not completed.
Repeat or recover
Repeat this action for every required variation of Keep focused components from being entirely hidden and after a material target, content, state, environment or configuration change. Preserve the original observation.
Limitations
This WCAG 2.4.11 Focus Not Obscured (Minimum) scenario covers only the action named Repeat material variations and recovery for the recorded target and state. It contributes evidence to 2.4.11; apply the procedure's aggregation, complete-process and conformance-scope rules before making a broader decision.
If you are new to this test
For WCAG 2.4.11 Focus Not Obscured (Minimum), change one material condition at a time where practical. Do not assume that a passing default state covers errors, overlays, orientation changes, interruptions or recovery.
Record this step

Step 4

Apply branches and exceptions

Purpose: For WCAG 2.4.11 Focus Not Obscured (Minimum), execute the named scenario: Apply branches and exceptions. Target: Each component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present. Compare the observation with this result: Every alternative branch or exception used is named and supported by its exact condition.

User impact: Users may not see or operate the focused control. This scenario isolates that risk in the action named Apply branches and exceptions.

For WCAG 2.4.11, compare the actual result directly with the normative condition; do not add advisory practice to the pass threshold. Evaluate only these recorded normative exceptions where relevant: User-movable content positions; User-opened content with reveal.

Expected result

Every alternative branch or exception used is named and supported by its exact condition.

Failure observation

After the tester completes the WCAG 2.4.11 Focus Not Obscured (Minimum) scenario named Apply branches and exceptions, the recorded observation for the target is inconsistent with the required result: Every alternative branch or exception used is named and supported by its exact condition.

Setup, evidence and decision guidance
Target
Each component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present.
Required state
For WCAG 2.4.11, use the same Keep focused components from being entirely hidden target and state evidence collected in S2.
Tool or command
WCAG 2.2 normative text and Understanding Success Criterion 2.4.11: Focus Not Obscured (Minimum) as informative interpretation.
Record
Selected branch; exception name, condition and evidence; unresolved judgement and resolver.
Pass
Record passed for the WCAG 2.4.11 Focus Not Obscured (Minimum) scenario named Apply branches and exceptions only when the evidence (Selected branch; exception name, condition and evidence; unresolved judgement and resolver.) supports: Every alternative branch or exception used is named and supported by its exact condition.
Fail
Record failed when the action is completed and this failure observation is reproduced: After the tester completes the WCAG 2.4.11 Focus Not Obscured (Minimum) scenario named Apply branches and exceptions, the recorded observation for the target is inconsistent with the required result: Every alternative branch or exception used is named and supported by its exact condition.
Not applicable
The completed scope inventory contains no target matching: Each component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present.
Blocked
Record blocked, not passed, when The target is applicable, but a required action, state, environment or evidence item was not completed.
Repeat or recover
Reassess WCAG 2.4.11 when source status, normative wording or the Keep focused components from being entirely hidden target facts change.
Limitations
This WCAG 2.4.11 Focus Not Obscured (Minimum) scenario covers only the action named Apply branches and exceptions for the recorded target and state. It contributes evidence to 2.4.11; apply the procedure's aggregation, complete-process and conformance-scope rules before making a broader decision.

Decide

How to decide

Passed

The component receiving keyboard focus is not entirely hidden by author-created content.

Failed

At least one applicable target violates this condition and no documented normative exception applies: The component receiving keyboard focus is not entirely hidden by author-created content.

Not applicable
The completed scope inventory contains no target matching: Each component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present.
Cannot tell
Focus location or whether the obscuring layer is author-created cannot be established.
Not tested
The target is applicable, but a required action, state, environment or evidence item was not completed.
Aggregation and reporting boundaries

Aggregation: Preserve one result per target and material state. A failed target prevents a passed aggregate; cantTell and untested remain unresolved; inapplicable is used only when no target matches applicability.

WCAG decision: A WCAG 2.4.11 decision is separate from target and ACT outcomes. It requires all applicable content in the declared conformance scope plus WCAG's full-page, complete-process, accessibility-supported-ways and non-interference requirements as applicable.

Automation: A passed automated or ACT check covers only its exact applicability and expectation. Complete all remaining manual, contextual, exception, state and technology checks; never set the criterion to satisfied automatically.

Worked example and outcome calibration

A11Y-WCAG-034-WORKED-001: representative worked example

Context: Representative synthetic example for WCAG 2.4.11 Focus Not Obscured (Minimum) on a fictional, version-frozen product target; no client or participant execution occurred.

Inspected: The tester follows S2 (Keep focused components from being entirely hidden) using the target, required state, tool and repeat rule stated in this procedure.

Observed output: After the tester completes the WCAG 2.4.11 Focus Not Obscured (Minimum) scenario named Keep focused components from being entirely hidden, the recorded observation for the target is inconsistent with the required result: The component receiving keyboard focus is not entirely hidden by author-created content.

Evidence:

  • example-evidence-001: target and state record for Each component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present.
  • example-evidence-002: contemporaneous observation from the named method — Focused component, overlay, viewport, focus sequence, visibility and reveal action where applicable.
  • 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: The component receiving keyboard focus is not entirely hidden by author-created content. The failed decision is limited to this synthetic target and state; unexecuted coverage is not inferred.

Decision: failed

Finding: A11Y-WCAG-034-example-finding-001 — Keep focused components from being entirely hidden: expected result is not demonstrated. The represented barrier may affect People who use keyboards, switches, speech input or adapted pointing devices.; People with low vision or reduced contrast sensitivity.

Remediation: Change the represented target or process so it demonstrates this result: The component receiving keyboard focus is not entirely hidden by author-created content. 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 Keep focused components from being entirely hidden 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
A sticky header leaves part of each focused navigation item visible.

The applicable target meets the criterion-specific condition in the stated state.

Failed
A cookie banner entirely covers the focused submit button and cannot be dismissed or revealed without moving focus.

The applicable target violates the condition and no supported exception applies.

Not applicable
The frozen scope contains no target matching: Each component as it receives keyboard focus while author-created sticky, fixed, modal or overlay content is present.

No target matches applicability; this target outcome is not automatically copied to a WCAG decision.

Cannot tell
Focus location or whether the obscuring layer is author-created cannot be established.

The uncertainty is material and remains unresolved rather than being converted to passed.

Not tested
An applicable keep focused components from being entirely hidden target was inventoried, but a required state or action was not executed.

Applicable coverage remains incomplete.

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.

  • 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.
