Focus indicators follow an organizational style guide.

There is a visible indicator of pointer focus.

The focus does not move to a position outside the current viewport, unless a mechanism is available to return to the previous focus point.

A user can focus on a content “area,” such as a modal or pop-up, then resume their view of all content using a limited number of steps.

The keyboard focus moves sequentially through content in an order and way that preserves meaning and operability.

When the focus is moved by the content into a temporary change of view (e.g. a modal), the focus is restored to its previous location when returned from the temporary change of view.

The focus order does not include repetitive, hidden, or static elements.

Interactive components with the same functionality behave consistently.

Interactive components with the same functionality have consistent labels.

Interactive components that have similar function and behavior have a consistent visual design.

Interactive components are visually and programmatically located in conventional locations.

Interactive components follow established conventions.

Conventional interactive components are used.

Interactive components retain their position unless a user changes the viewport or moves the component.

Visual information required to identify user interface components and states meet a minimum contrast ratio test, except for inactive components or where the appearance of the component is determined by the user agent and not modified by the author.

The importance of interactive components is indicated.

Interactive components have visible labels that identify the purpose of the component.

Changes to interactive components’ names, roles, values or states are visually and programmatically indicated.

Interactive components are visually distinguishable without interaction from static content and include visual cues on how to use them.

Field constraints and conditions (required line length, date format, password format, etc.) are available.

Inputs have visible labels that identify the purpose of the input.

The programmatic name includes the visual label.

Accurate names, roles, values, and states are available for interactive components.

Any input modality available on a platform can be used concurrently.

Users can dismiss additional content (triggered by hover) without moving the pointer, unless the additional content communicates an input error or does not obscure or replace other content.

Interactive components are available to all navigation and input methods.

Changes in content and updates notify users, regardless of the update speed.

Notification is provided when viewing content that was previously viewed is changed.

Interactive components that can alter the order of content convey their purpose prior to activation, and convey their impact on content order when activated.

Components that trigger a 'change of context' are indicated, or the change of context can be reversed.

The combined target size and spacing to adjacent targets is at least 24x24 pixels

The combined target size and spacing to adjacent targets is at least 48x48 pixels.

The number of input commands required to complete a task using the keyboard is similar to the number of input commands when using other input modalities.

Authored keyboard commands do not conflict with platform commands or they can be remapped.

Keyboard interface interactions are consistent.

If the keyboard is non-hardware (such as a virtual keyboard), the keyboard input mode is indicated.

All functionality must be accessible through the keyboard, except when a task requires input based on the user's specific input action.

If keyboard focus can be moved to an interactive component, then the keyboard focus can be moved away from that component, or the component can be dismissed, with focus returning to the previous point.

The user is informed of non-standard authored keyboard commands.

Selecting an interactive component with a pointer sets the focus to that element.

Every function that can be operated by a pointer, can be operated by a single pointer input or a sequence of single pointer inputs without requiring certain timing.

Functionality which supports pointers is available to any pointer device supported by the platform.

The method of pointer cancellation is consistent.

Where specific pressures are used, they can be adjusted and/or disabled without loss of function.

Where specific speeds are used, they can be adjusted and/or disabled without loss of function.

All functionality that requires full or gross body movement may also be accomplished with a standard input device.

All functionality can be completed without reorienting or repositioning hardware devices.

Error notifications are programmatically associated with the error source so that users can access the error information while focused on the source of the error.

Errors are visually identifiable without relying on only text, only color, or only symbols.

Errors that can be automatically detected are identified and described to the user.

Error notifications persist until the user dismisses them or the error is resolved.

Error notifications are visually collocated with the source of the error within the viewport, or provide a link to the source of the error which, when activated, moves the viewport to the error.

Audio shifting designed to create a perception of motion is avoided; or can be paused or prevented.

Flashing or strobing beyond thresholds defined by safety standards are avoided; or can be paused or prevented.

Visual motion and pseudo-motion that lasts longer than 5 seconds is avoided; or can be paused or prevented.

Visual motion and pseudo-motion triggered by interaction is avoided; or can be prevented, unless the animation is essential to the functionality or the information being conveyed.

The relationships between parts of the content is clearly indicated.

The starting point or home is visually and programmatically labeled.

Relationships that convey meaning between pieces of content are programmatically determinable. Note: Examples of relationships include items positioned next to each other, arranged in a hierarchy, or visually grouped.

Sections are visually and programmatically distinguishable.

The relative order of content and interactions remain consistent throughout a workflow. Note: Relative order means that content can be added or removed, but repeated items are in the same order relative to each other.

Navigation features are available regardless of screen size and magnification (responsive design)

Automated input from user agents, 3rd party tools, or copy-and-paste is not prevented.

Processes, including authentication, can be completed without puzzles, calculations, or other cognitive tests (essential exceptions would apply).

Processes can be completed without memorizing and recalling information from previous stages of the process.

For each process with a time-limit, a mechanism exists to disable or extend the limit before the time-limit starts.

For each process with a time-limit, a mechanism exists to disable or extend the time-limit at timeout.

For each process with a time-limit, a mechanism exists to disable the limit.

Process completion does not include exploitive behaviors.

Processes can be completed without navigating misinformation or redirections.

Preselected options are visible by default during process completion without additional interactions.

A mechanism is available to prevent fraudulent redirection or alert users they are exiting the site.

In a multistep process, the interface supports stepping backwards in a process and returning to the current point without data loss.

Information previously entered by or provided to the user that is required to be entered again in the same process is either auto-populated, or available for the user to select.

Data entry and other task completion processes allow saving and resuming from the current step in the task.

In a process, the interface indicates when user input or action is required to proceed to the next step. c

Information needed to complete a multi-step process is provided at the start of the process, including:

• number of steps it might take (if known in advance),
• details of any resources needed to perform the task, and
• overview of the process and next step.

The steps and instructions needed to complete a multistep process are available

The author or source of the primary content is visually and programmatically indicated.

Third party content (AI, Advertising, etc.) is visually and programmatically indicated.

Advertising and other third-party content that obscures the primary content can be moved or removed without interacting with the advertising or third-party content.

The interface indicates when a user is entering an agreement or submitting data.

Disability information is not disclosed to or used by third parties and algorithms (including AI).
