No audio description is needed because no video is used.

Adaptable

1.3.1 Info and Relationships

Level A

N/A

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

Equation images don't use visual cues to convey information.

1.3.2 Meaningful Sequence

Level A

Yes

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

The accessible text of the equations shows every symbol present, and mathematical matrices and arrays are read out in the correct row and column order.

1.3.3 Sensory Characteristics

Level A

N/A

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.

NOTE

For requirements related to color, refer to

Equation images don’t rely on shape and/or location to convey information.

1.3.4 Orientation

Level AA

N/A

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.

Equation images don’t depend on orientation.

1.3.5 Identify Input Purpose

Level AA

N/A

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; and

• The content is implemented using technologies with support for identifying the expected meaning for form input data.

Equation images don't use input fields, they are edited via the authoring tool.

Distinguishable

1.4.1 Use of Color

Level A

N/A

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

Equation images don’t use color on their own to convey information. If they do, the author is responsible for providing additional information in the accessible text.

1.4.2 Audio Control

Level A

N/A

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.

Equation images do not contain audio.

1.4.3 Contrast (Minimum)

Level AA

N/A

The visual presentation of text and images of text has a contrast ratio of at least 4.5:1, except for the following:

• Large Text:

Large-scale text and images of large-scale text have a contrast ratio of at least 3:1;

• Incidental:

Text or images of text that are part of an inactive user interface component, that are pure decoration, that are not visible to anyone, or that are part of a picture that contains significant other visual content, have no contrast requirement.

• Logotypes:

Text that is part of a logo or brand name has no contrast requirement.

Equation images are compliant with minimum contrast requirements. By default, equation images use black on white background.

1.4.4 Resize Text

Level AA

Yes

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

The equation can be resized using the host application or by increasing the font size.

1.4.5 Images of text

Level AA

Yes

If the technologies being used can achieve the visual presentation, text is used to convey information rather than images of text except for the following:

• Customizable:

The image of text can be visually customized to the user's requirements;

• Essential:

A particular presentation of text is essential to the information being conveyed.

NOTE

Logotypes (text that is part of a logo or brand name) are considered essential.

Equations produced by MathType are images of text, and they have alternative, descriptive accessible text representations.

1.4.10 Reflow

Level AA

N/A

Content can be presented without loss of information or functionality, and without requiring scrolling in two dimensions for:

• Vertical scrolling content at a width equivalent to 320 CSS pixels;

• Horizontal scrolling content at a height equivalent to 256 CSS pixels.

Except for parts of the content which require two-dimensional layout for usage or meaning.

NOTE

Note: 320 CSS pixels is equivalent to a starting viewport width of 1280 CSS pixels wide at 400% zoom. For web content which are designed to scroll horizontally (e.g. with vertical text), the 256 CSS pixels is equivalent to a starting viewport height of 1024px at 400% zoom.

NOTE

Examples of content which require two-dimensional layout are images, maps, diagrams, video, games, presentations, data tables, and interfaces where it is necessary to keep toolbars in view while manipulating content.

Size restrictions do not apply to equation images.

1.4.11 Non Text contrast

Level AA

Yes

The visual presentation of the following have a contrast ratio of at least 3:1 against adjacent color(s):

• User Interface Components:

Visual information required to identify user interface components and states, except for inactive components or where the appearance of the component is determined by the user agent and not modified by the author;

• Graphical Objects:

Parts of graphics required to understand the content, except when a particular presentation of graphics is essential to the information being conveyed.

Equation images are compliant with minimum contrast requirements. By default, equation images use black on white background.

1.4.12 Text Spacing

Level AA

In content implemented using markup languages that support the following text style properties, no loss of content or functionality occurs by setting all of the following and by changing no other style property:

• Line height (line spacing) to at least 1.5 times the font size;

• Spacing following paragraphs to at least 2 times the font size;

• Letter spacing (tracking) to at least 0.12 times the font size;

• Word spacing to at least 0.16 times the font size.

Exception: Human languages and scripts that do not make use of one or more of these text style properties in written text can conform using only the properties that exist for that combination of language and script.

This criteria does not apply to equation images.

1.4.13 Content on Hover or Focus

Level AA

Yes

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

• Dismissable:

A mechanism is available to dismiss the additional content without moving pointer hover or keyboard focus, unless the additional content communicates an input error or does not obscure or replace other content;

• Hoverable:

If pointer hover can trigger the additional content, then the pointer can be moved over the additional content without the additional content disappearing;

• Persistent:

The additional content remains visible until the hover or focus trigger is removed, the user dismisses it, or its information is no longer valid.

Exception: The visual presentation of the additional content is controlled by the user agent and is not modified by the author.

NOTE

Examples of additional content controlled by the user agent include browser tooltips created through use of the HTML title attribute.

NOTE

Custom tooltips, sub-menus, and other nonmodal popups that display on hover and focus are examples of additional content covered by this criterion.

Equation images don't produce any tooltips. However, some host applications like Word or Docs might trigger a tooltip when an image is selected and it is responsibility of these applications to make it accessible. No issues have been detected.

Operable

Keyboard Accessible

2.1.1 Keyboard

Level A

N/A

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.

NOTE

This exception relates to the underlying function, not the input technique. For example, if using handwriting to enter text, the input technique (handwriting) requires path-dependent input but the underlying function (text input) does not.

Since there is nothing to focus, equation images do not need keyboard navigation.

2.1.2 No Keyboard Trap

Level A

N/A

zIf 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.

Equation images are focusable via the host application and they can be unfocused like any other selectable element.

2.1.4 Character Key shortcuts

Level A

N/A

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:

A mechanism is available to turn the shortcut off;

• Remap:

A mechanism is available to remap the shortcut to use one or more non-printable keyboard characters (e.g. Ctrl, Alt, etc);

• Active only on focus:

The keyboard shortcut for a user interface component is only active when that component has focus.

Shortcuts do not apply to equation images.

Enough time

2.2.1 Timing Adjustable

Level A

N/A

For each time limit that is set by the content, at least one of the following is true:

• Turn off:

The user is allowed to turn off the time limit before encountering it; or

• Adjust:

The user is allowed to adjust the time limit before encountering it over a wide range that is at least ten times the length of the default setting; or

• Extend:

The user is warned before time expires and given at least 20 seconds to extend the time limit with a simple action (for example, "press the space bar"), and the user is allowed to extend the time limit at least ten times; or

• Real-time Exception:

The time limit is a required part of a real-time event (for example, an auction), and no alternative to the time limit is possible; or

• Essential Exception:

The time limit is essential and extending it would invalidate the activity; or

• 20 Hour Exception:

The time limit is longer than 20 hours.

NOTE

This success criterion helps ensure that users can complete tasks without unexpected changes in content or context that are a result of a time limit. This success criterion should be considered in conjunction with

Images do not have timeout limitations.

2.2.2 Pause, Stop, Hide

Level A

N/A

For moving, blinking, scrolling, or auto-updating information, all of the following are true:

• Moving, blinking, scrolling:

For any moving, blinking or scrolling information that (1) starts automatically, (2) lasts more than five seconds, and (3) is presented in parallel with other content, there is a mechanism for the user to pause, stop, or hide it unless the movement, blinking, or scrolling is part of an activity where it is essential; and

• Auto-updating:

For any auto-updating information that (1) starts automatically and (2) is presented in parallel with other content, there is a mechanism for the user to pause, stop, or hide it or to control the frequency of the update unless the auto-updating is part of an activity where it is essential.

Images do not have timeout limitations.

Seizures and Physical Reactions

2.3.1 Three Flashes or below Threshold

Level A

N/A

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.

Equation images do not contain flashing content.

Navigable

2.4.1 Bypass blocks

Level A

N/A

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

Equation images don't contain repeated content, only what the author provides.

2.4.2 Page Title

Level A

N/A

Web pages have titles that describe topic or purpose.

Equation images do not need a title.

2.4.3 Focus Order

Level A

N/A

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.

Equation images are focused depending on where they are inserted in a document, and the order is properly kept. This is the responsibility of the host application.

2.4.4 Link Purpose in Context

Level A

N/A

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.

Equation images do not contain links.

2.4.5 Multiple Ways

Level AA

N/A

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.

Equation images cannot be considered as a set of web pages or software. This requirement does not apply.

2.4.6 Headings and Labels

Level AA

N/A

Headings and labels describe topic or purpose.

Equation images don't contain headings or labels.

2.4.7 Focus Visible

Level AA

Yes

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

When an equation image is focused, it is visually highlighted.

Input Modalities

2.5.1 Pointer Gestures (for content)

Level A

N/A

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.

NOTE

This requirement applies to web content that interprets pointer actions (i.e. this does not apply to actions that are required to operate the user agent or assistive technology).

Multi-point gestures do not apply to equation images.

2.5.2 Pointer Cancellation

Level A

N/A

For functionality that can be operated using a single pointer, at least one of the following is true:

• No Down-Event:

The down-event of the pointer is not used to execute any part of the function;

• Abort or Undo:

Completion of the function is on the up-event, and a mechanism is available to abort the function before completion or to undo the function after completion;

• Up Reversal:

The up-event reverses any outcome of the preceding down-event;

• Essential:

Completing the function on the down-event is essential.

NOTE

Functions that emulate a keyboard or numeric keypad key press are considered essential.

NOTE

This requirement applies to web content that interprets pointer actions (i.e. this does not apply to actions that are required to operate the user agent or assistive technology).

The gestures which apply to images don't fall under the responsibility of MathType.

2.5.3 Label in Name

Level A

Yes

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

NOTE

A best practice is to have the text of the label at the start of the name.

Equation images don't contain labels.

2.5.4 Motion actuation

Level A

N/A

Functionality that can be operated by device motion or user motion can also be operated by user interface components and responding to the motion can be disabled to prevent accidental actuation, except when:

• Supported Interface:

The motion is used to operate functionality through an accessibility supported interface;

• Essential:

The motion is essential for the function and doing so would invalidate the activity.

MathType does not provide motion based interaction for equation images. Any interaction would be provided by the host application.

Understandable

Readable

3.1.1 Language of Page

Level A

Yes

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

Alternative (accessible) text for equation images depends on the language of the host application where it is created (English by default).

3.1.2 Language of Parts

Level AA

Yes

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.

The language of the equation remains consistent throughout the entire equation, all symbols are properly translated.

Predictable

3.2.1 On Focus

Level A

N/A

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

This criteria does not apply to equation images as focus depends on the host application.

3.2.2 On Input

Level A

N/A

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.

Changes of context are not the responsibility of equation images.

3.2.3 Consistent Navigation

Level AA

N/A

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.

Equation images are single components, integrated in third party applications.

3.2.4 Consistent Identification

Level AA

N/A

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

Equation images are single components, integrated in third party applications.

Input Assistance

3.3.1 Error Identification

Level A

N/A

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.

Equation images don't contain any form of input.

3.3.2 Lables or Instructions

Level A

N/A

Labels or instructions are provided when content requires user input.

No instructions or labels are provided in equation images.

3.3.3 Error suggestions

Level AA

N/A

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.

No error suggestions are used in equation images.

3.3.4 Error Prevention (for Legal and Financial Data)

Level AA

N/A

For Web pages that cause legal commitments or financial transactions for the user to occur, that modify or delete user-controllable data in data storage systems, or that submit user test responses, at least one of the following is true:

• Reversible:

Submissions are reversible.

• Checked:

Data entered by the user is checked for input errors and the user is provided an opportunity to correct them.

• Confirmed:

A mechanism is available for reviewing, confirming, and correcting information before finalizing the submission.

There aren't any forms in equation images.

Robust

Compatible

4.1.1 Parsing (for markup content)

Level A

Yes

In content implemented using markup languages, elements have complete start and end tags, elements are nested according to their specifications, elements do not contain duplicate attributes, and any IDs are unique, except where the specifications allow these features.

NOTE

Start and end tags that are missing a critical character in their formation, such as a closing angle bracket or a mismatched attribute value quotation mark are not complete.

Equation images use MathML for their content, which is properly formatted.

4.1.2 Name, Role, Value

Level A

N/A

For all user interface components (including but not limited to: form elements, links and components generated by scripts), 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.

NOTE

This success criterion is primarily for Web authors who develop or script their own user interface components. For example, standard HTML controls already meet this success criterion when used according to specification.

This requirement does not apply to equation images.

4.1.3 Status Messages

Level AA

N/A

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.

Equation images don't contain status messages.
