Information, structure, and relationships conveyed through presentation can be programmatically determined or are available in text.

Info and Relationships

When the sequence in which content is presented affects its meaning, a correct reading sequence can be programmatically determined.

Meaningful Sequence

Instructions provided for understanding and operating content do not rely solely on sensory characteristics of components such as shape, color, size, visual location, orientation, or sound.

Sensory Characteristics

Content does not restrict its view and operation to a single display orientation, such as portrait or landscape, unless a specific display orientation is essential.

Orientation

The purpose of each input field collecting information about the user can be programmatically determined when the input field serves a purpose identified in the Input Purposes for user interface components section.

Identify Input Purpose

In content implemented using markup languages, the purpose of user interface components, icons, and regions can be programmatically determined.

Identify Purpose

Color is not used as the only visual means of conveying information, indicating an action, prompting a response, or distinguishing a visual element.

Use of Color

If any audio on a web page plays automatically for more than 3 seconds, either a mechanism is available to pause or stop the audio, or a mechanism is available to control audio volume independently from the overall system volume level.

Audio Control

The visual presentation of text and images of text has a contrast ratio of at least 4.5:1, except for large text (3:1), incidental, or logotypes.

Contrast (Minimum)

Except for captions and images of text, text can be resized without assistive technology up to 200 percent without loss of content or functionality.

Resize text

If the technologies being used can achieve the visual presentation, text is used to convey information rather than images of text except for customizable or essential cases.

Images of Text

The visual presentation of text and images of text has a contrast ratio of at least 7:1, except for large text (4.5:1), incidental, or logotypes.

Contrast (Enhanced)

For prerecorded audio-only content that contains primarily speech in the foreground, is not an audio CAPTCHA or audio logo, and is not vocalization intended to be primarily musical expression such as singing or rapping, at least one of the following is true: no background, turn off, or 20 dB.

Low or No Background Audio

For the visual presentation of blocks of text, a mechanism is available to achieve the following: foreground and background colors can be selected, width is no more than 80 characters or glyphs, text is not justified, line spacing is at least space-and-a-half within paragraphs, paragraph spacing is at least 1.5 times larger than line spacing, and text can be resized without assistive technology up to 200 percent.

Visual Presentation

Images of text are only used for pure decoration or where a particular presentation of text is essential to the information being conveyed.

Images of Text (No Exception)

Content can be presented without loss of information or functionality, and without requiring scrolling in two dimensions for vertical scrolling content at 320 CSS pixels width or horizontal scrolling content at 256 CSS pixels height.

Reflow

The visual presentation of user interface components and graphical objects has a contrast ratio of at least 3:1 against adjacent color(s).

Non-text Contrast

In content implemented using markup languages that support the following text style properties, no loss of content or functionality occurs by setting line height to at least 1.5 times the font size, spacing following paragraphs to at least 2 times the font size, letter spacing to at least 0.12 times the font size, and word spacing to at least 0.16 times the font size.

Text Spacing

Where receiving and then removing pointer hover or keyboard focus triggers additional content to become visible and then hidden, the following are true: dismissible, hoverable, persistent.

Content on Hover or Focus

All functionality of the content is operable through a keyboard interface without requiring specific timings for individual keystrokes, except where the underlying function requires input that depends on the path of the user's movement and not just the endpoints.

Keyboard

If keyboard focus can be moved to a component of the page using a keyboard interface, then focus can be moved away from that component using only a keyboard interface, and, if it requires more than unmodified arrow or tab keys or other standard exit methods, the user is advised of the method for moving focus away.

No Keyboard Trap

All functionality of the content is operable through a keyboard interface without requiring specific timings for individual keystrokes.

Keyboard (No Exception)

If a keyboard shortcut is implemented in content using only letter (including upper- and lower-case letters), punctuation, number, or symbol characters, then at least one of the following is true: turn off, remap, or active only on focus.

Character Key Shortcuts

For each time limit that is set by the content, at least one of the following is true: turn off, adjust, extend, real-time exception, essential exception, or 20 hour exception.

Timing Adjustable

For moving, blinking, scrolling, or auto-updating information, a mechanism for the user to pause, stop, or hide it is available unless the movement is part of an activity where it is essential.

Pause, Stop, Hide

Timing is not an essential part of the event or activity presented by the content, except for non-interactive synchronized media and real-time events.

No Timing

Interruptions can be postponed or suppressed by the user, except interruptions involving an emergency.

Interruptions

When an authenticated session expires, the user can continue the activity without loss of data after re-authenticating.

Re-authenticating

Users are warned of the duration of any user inactivity that could cause data loss, unless the data is preserved for more than 20 hours when the user does not take any actions.

Timeouts

Web pages do not contain anything that flashes more than three times in any one second period, or the flash is below the general flash and red flash thresholds.

Three Flashes or Below Threshold

Web pages do not contain anything that flashes more than three times in any one second period.

Three Flashes

Motion animation triggered by interaction can be disabled, unless the animation is essential to the functionality or information being conveyed.

Animation from Interactions

A mechanism is available to bypass blocks of content that are repeated on multiple web pages.

Bypass Blocks

Web pages have titles that describe topic or purpose.

Page Titled

If a web page can be navigated sequentially and the navigation sequences affect meaning or operation, focusable components receive focus in an order that preserves meaning and operability.

Focus Order

The purpose of each link can be determined from the link text alone or from the link text together with its programmatically determined link context, except where the purpose of the link would be ambiguous to users in general.

Link Purpose (In Context)

More than one way is available to locate a web page within a set of web pages except where the web page is the result of, or a step in, a process.

Multiple Ways

Headings and labels describe topic or purpose.

Headings and Labels

Any keyboard operable user interface has a mode of operation where the keyboard focus indicator is visible.

Focus Visible

Information about the user's location within a set of web pages is available.

Location

A mechanism is available to allow the purpose of each link to be identified from link text alone, except where the purpose of the link would be ambiguous to users in general.

Link Purpose (Link Only)

Section headings are used to organize the content.

Section Headings

When a user interface component receives keyboard focus, the component is not entirely hidden behind author-created content.

Focus Not Obscured (Minimum)

When a user interface component receives keyboard focus, no part of the component is hidden behind author-created content.

Focus Not Obscured (Enhanced)

When the keyboard focus indicator is visible, an area of the focus indicator meets the following: is at least as large as the area of a 2 CSS pixel thick perimeter of the unfocused component or sub-component, and has a contrast ratio of at least 3:1 between the same pixels in the focused and unfocused states.

Focus Appearance

All functionality that uses multipoint or path-based gestures for operation can be operated with a single pointer without a path-based gesture, unless a multipoint or path-based gesture is essential.

Pointer Gestures

For functionality that can be operated using a single pointer, at least one of the following is true: no down-event, abort or undo, up reversal, or essential.

Pointer Cancellation

For user interface components with labels that include text or images of text, the name contains the text that is presented visually.

Label in Name

Motion Actuation

The size of the target for pointer inputs is at least 44 by 44 CSS pixels except when equivalent, inline, user agent control, or essential.

Target Size (Enhanced)

Web content does not restrict use of input modalities available on a platform except where the restriction is essential, required to ensure the security of the content, or required to respect user settings.

Concurrent Input Mechanisms

All functionality that uses a dragging movement for operation can be achieved by a single pointer without dragging, unless dragging is essential or the functionality is determined by the user agent and not modified by the author.

Dragging Movements

The size of the target for pointer inputs is at least 24 by 24 CSS pixels, except when spacing, equivalent, inline, user agent control, or essential.

Target Size (Minimum)

The default human language of each web page can be programmatically determined.

Language of Page

The human language of each passage or phrase in the content can be programmatically determined except for proper names, technical terms, words of indeterminate language, and words or phrases that have become part of the vernacular of the immediately surrounding text.

Language of Parts

A mechanism is available for identifying specific definitions of words or phrases used in an unusual or restricted way, including idioms and jargon.

Unusual Words

A mechanism for identifying the expanded form or meaning of abbreviations is available.

Abbreviations

When text requires reading ability more advanced than the lower secondary education level after removal of proper names and titles, supplemental content, or a version that does not require reading ability more advanced than the lower secondary education level, is available.

Reading Level

A mechanism is available for identifying specific pronunciation of words where meaning of the words, in context, is ambiguous without knowing the pronunciation.

Pronunciation

When any user interface component receives focus, it does not initiate a change of context.

On Focus

Changing the setting of any user interface component does not automatically cause a change of context unless the user has been advised of the behavior before using the component.

On Input

Navigational mechanisms that are repeated on multiple web pages within a set of web pages occur in the same relative order each time they are repeated, unless a change is initiated by the user.

Consistent Navigation

Components that have the same functionality within a set of web pages are identified consistently.

Consistent Identification

Changes of context are initiated only by user request or a mechanism is available to turn off such changes.

Change on Request

If a web page contains any help mechanisms, and those mechanisms are repeated on multiple web pages within a set of web pages, they occur in the same order relative to other page content, unless a change is initiated by the user.

Consistent Help

If an input error is automatically detected, the item that is in error is identified and the error is described to the user in text.

Error Identification

Labels or instructions are provided when content requires user input.

Labels or Instructions

If an input error is automatically detected and suggestions for correction are known, then the suggestions are provided to the user, unless it would jeopardize the security or purpose of the content.

Error Suggestion

Accessible Authentication

A cognitive function test is not required for any step in an authentication process unless that step provides at least one of the following: alternative or mechanism.

Accessible Authentication (No Exception)

Parsing

For all user interface components, the name and role can be programmatically determined; states, properties, and values that can be set by the user can be programmatically set; and notification of changes to these items is available to user agents, including assistive technologies.

Name, Role, Value

In content implemented using markup languages, status messages can be programmatically determined through role or properties such that they can be presented to the user by assistive technologies without receiving focus.
