Voluntary Product Accessibility Template®
Criteria Supporting Features Remarks and explanations
(a) When software is designed to run on a system that has a keyboard, product functions shall be executable from a keyboard where the function itself or the result of performing a function can be discerned textually. Supports We strive to make sure all sections of Canvas can be navigated and controlled with only a keyboard.
(b) Applications shall not disrupt or disable activated features of other products that are identified as accessibility features, where those features are developed and documented according to industry standards. Applications also shall not disrupt or disable activated features of any operating system that are identified as accessibility features where the application programming interface for those accessibility features has been documented by the manufacturer of the operating system and is available to the product developer. Supports Canvas does not interfere with any operating system or browser shortcuts. Accessibility features such as sticky keys, magnifiers, screen readers, cursor sizes and virtual keyboards are not disabled or disrupted by Canvas.
(c) A well-defined on-screen indication of the current focus shall be provided that moves among interactive interface elements as the input focus changes. The focus shall be programmatically exposed so that Assistive Technology can track focus and focus changes. Supports Where possible, Canvas uses default browser focus styles. Where those styles are overridden, Canvas provides distinct focus styles.
(d) Sufficient information about a user interface element including the identity, operation and state of the element shall be available to Assistive Technology. When an image represents a program element, the information conveyed by the image must also be available in text. Supports Provided by the browser.
(e) When bitmap images are used to identify controls, status indicators, or other programmatic elements, the meaning assigned to those images shall be consistent throughout an application's performance. Supports Canvas uses icons to help depict the purpose of certain interface elements, such as "+" add buttons. The use of these icons is consistent throughout the site. Whenever a single graphic is used, such as a lone "+" graphic, alt text or CSS text replacement is used to enable screen readers to read the purpose of the link/button to the user.
(f) Textual information shall be provided through operating system functions for displaying text. The minimum information that shall be made available is text content, text input caret location, and text attributes. Supports Provided by the browser.
(g) Applications shall not override user selected contrast and color selections and other individual display attributes. Not applicable  
(h) When animation is displayed, the information shall be displayable in at least one non-animated presentation mode at the option of the user. Not applicable  
(i) Color coding shall not be used as the only means of conveying information, indicating an action, prompting a response, or distinguishing a visual element. Supports Canvas does not use color alone to distinguish the importance of a visual element.
(j) When a product permits a user to adjust color and contrast settings, a variety of color selections capable of producing a range of contrast levels shall be provided. Supports The interface of Canvas has been styled with CSS to comply with Section 508's contrast and color settings. Institutions may be able to theme Canvas for institutional branding, but Instructure monitors the process to ensure that color and contrast remain compliant.
(k) Software shall not use flashing or blinking text, objects, or other elements having a flash or blink frequency greater than 2 Hz and lower than 55 Hz. Supports Canvas does not use flashing or blinking text.
(l) When electronic forms are used, the form shall allow people using Assistive Technology to access the information, field elements, and functionality required for completion and submission of the form, including all directions and cues. Supports Canvas and all forms in the application work well with screen readers such as JAWS or VoiceOver.

Criteria Supporting Features Remarks and explanations
(a) A text equivalent for every non-text element shall be provided (e.g., via "alt", "longdesc", or in element content). Supports Meaningful images in the Canvas user interface have alt-text descriptions. Non-relevant images have no alt-text.
(b) Equivalent alternatives for any multimedia presentation shall be synchronized with the presentation. Supports Canvas does not contain built-in multimedia presentations. Users upload their own content and are responsible for ensuring the accessibility of the uploaded content.
(c) Web pages shall be designed so that all information conveyed with color is also available without color, for example from context or markup. Supports Canvas does not use color alone to distinguish the importance of a visual element.
(d) Documents shall be organized so they are readable without requiring an associated style sheet. Supports A user or screen reader can read and understand pages in Canvas with the associated style sheets disabled.
(e) Redundant text links shall be provided for each active region of a server-side image map. Supports Canvas does not use server-side image maps.
(f) Client-side image maps shall be provided instead of server-side image maps except where the regions cannot be defined with an available geometric shape. Supports Canvas does not use server-side image maps.
(g) Row and column headers shall be identified for data tables. Supports Data tables, such as the list of assignments and their due dates in the "syllabus" page, are marked up with informative column and row headers.
(h) Markup shall be used to associate data cells and header cells for data tables that have two or more logical levels of row or column headers. Supports Canvas has no data tables with two or more logical levels of row or column headers.
(i) Frames shall be titled with text that facilitates frame identification and navigation Supports Canvas does not use frames.
(j) Pages shall be designed to avoid causing the screen to flicker with a frequency greater than 2 Hz and lower than 55 Hz. Supports Canvas does not cause the screen to flicker with a frequency greater than 2 Hz and lower than 55 Hz.
(k) A text-only page, with equivalent information or functionality, shall be provided to make a web site comply with the provisions of this part, when compliance cannot be accomplished in any other way. The content of the text-only page shall be updated whenever the primary page changes. Supports Canvas is compliant with all provisions of this section, so a text-only version is unnecessary.
(l) When pages utilize scripting languages to display content, or to create interface elements, the information provided by the script shall be identified with functional text that can be read by Assistive Technology. Supports Canvas uses javascript, WAI-ARIA and the most modern HTML5 techniques to provide feedback from interactive elements and to allow Assistive Technology such as screen readers to read and transmit information back to the user.
(m) When a web page requires that an applet, plug-in or other application be present on the client system to interpret page content, the page must provide a link to a plug-in or applet that complies with §1194.21(a) through (l). Supports Canvas does not require any applet or plug-in to work with its default functionality. Users can upload their own multimedia content using Flash, but if users do not have Flash installed on their computer, they will be prompted with a link to download Flash.
(n) When electronic forms are designed to be completed on-line, the form shall allow people using Assistive Technology to access the information, field elements, and functionality required for completion and submission of the form, including all directions and cues. Supports Canvas and all forms in the application work well with screen readers such as JAWS or VoiceOver.
(o) A method shall be provided that permits users to skip repetitive navigation links. Supports Canvas has a "skip to content" link at the top of every page that will bypass all site and course navigation. Canvas also uses semantic HTML5 elements such as <nav>, <aside> and <footer>, as well as ARIA landmark roles such as "navigation", "complementary", "main" and "contentinfo" to cue Assistive Technology.

Note to 1194.22: The Board interprets paragraphs (a) through (k) of this section as consistent with the following priority 1 Checkpoints of the Web Content Accessibility Guidelines 1.0 (WCAG 1.0) (May 5 1999) published by the Web Accessibility Initiative of the World Wide Web Consortium: Paragraph (a) - 1.1, (b) - 1.4, (c) - 2.1, (d) - 6.1, (e) - 1.2, (f) - 9.1, (g) - 5.1, (h) - 5.2, (i) - 12.1, (j) - 7.1, (k) - 11.4.
