Touch device users, explore by touch or with swipe gestures. Office of Information Technology. Back to Top. How to use Zoom Basic with the 40 minute limit A Zoom Basic license only allows group meetings up to 40 minutes, but a typical course session lasts longer than that! Instructor schedules a meeting in Canvas. Students join the meeting. Instructor has pre-set a break for the meeting at 3 0 minutes or whatever time feels like a good stopping point.
At the minute mark, the instructor tells students they are taking a 5 minute break, and instructs students to return in 5 min. The instructor ends the meeting. Same meeting ID, same calendar invite, etc. This success criterion addresses color perception specifically.
Other forms of perception are covered in Guideline 1. 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. Since any content that does not meet this success criterion can interfere with a user’s ability to use the whole page, all content on the Web page whether or not it is used to meet other success criteria must meet this success criterion.
See Conformance Requirement 5: Non-Interference. The visual presentation of text and images of text has a contrast ratio of at least 4. Large-scale text and images of large-scale text have a contrast ratio of at least ;. 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.
Except for captions and images of text , text can be resized without assistive technology up to percent without loss of content or functionality.
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:. The image of text can be visually customized to the user’s requirements;. A particular presentation of text is essential to the information being conveyed. The visual presentation of text and images of text has a contrast ratio of at least , except for the following:.
Large-scale text and images of large-scale text have a contrast ratio of at least 4. The background sounds are at least 20 decibels lower than the foreground speech content, with the exception of occasional sounds that last for only one or two seconds. Per the definition of “decibel,” background sound that meets this requirement will be approximately four times quieter than the foreground speech content.
For the visual presentation of blocks of text , a mechanism is available to achieve the following:. Images of text are only used for pure decoration or where a particular presentation of text is essential to the information being conveyed.
Content can be presented without loss of information or functionality, and without requiring scrolling in two dimensions for:. For web content which are designed to scroll horizontally e. 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.
The visual presentation of the following have a contrast ratio of at least against adjacent color s :. 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:.
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.
Where receiving and then removing pointer hover or keyboard focus triggers additional content to become visible and then hidden, the following are true:. Exception: The visual presentation of the additional content is controlled by the user agent and is not modified by the author. Examples of additional content controlled by the user agent include browser tooltips created through use of the HTML title attribute. Custom tooltips, sub-menus, and other nonmodal popups that display on hover and focus are examples of additional content covered by this criterion.
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. 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.
This does not forbid and should not discourage providing mouse input or other input methods in addition to keyboard operation. 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.
Since any content that does not meet this success criterion can interfere with a user’s ability to use the whole page, all content on the Web page whether it is used to meet other success criteria or not must meet this success criterion. All functionality of the content is operable through a keyboard interface without requiring specific timings for individual keystrokes.
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:. 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.
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. 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. The time limit is essential and extending it would invalidate the activity; or.
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 Success Criterion 3. For moving, blinking , scrolling, or auto-updating information, all of the following are true:. 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.
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.
For requirements related to flickering or flashing content, refer to Guideline 2. Content that is updated periodically by software or that is streamed to the user agent is not required to preserve or present information that is generated or received between the initiation of the pause and resuming presentation, as this may not be technically possible, and in many situations could be misleading to do so. An animation that occurs as part of a preload phase or similar situation can be considered essential if interaction cannot occur during that phase for all users and if not indicating progress could confuse users or cause them to think that content was frozen or broken.
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. Interruptions can be postponed or suppressed by the user, except interruptions involving an emergency. When an authenticated session expires, the user can continue the activity without loss of data after 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. Privacy regulations may require explicit user consent before user identification has been authenticated and before user data is preserved.
In cases where the user is a minor, explicit consent may not be solicited in most jurisdictions, countries or regions. Consultation with privacy professionals and legal counsel is advised when considering data preservation as an approach to satisfy this success criterion.
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.
Web pages do not contain anything that flashes more than three times in any one second period. Motion animation triggered by interaction can be disabled, unless the animation is essential to the functionality or the information being conveyed. A mechanism is available to bypass blocks of content that are repeated on multiple Web pages. Web pages have titles that describe topic or purpose. 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.
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. 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.
Headings and labels describe topic or purpose. Any keyboard operable user interface has a mode of operation where the keyboard focus indicator is visible. Information about the user’s location within a set of Web pages is available.
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. Section headings are used to organize the content.
This success criterion covers sections within writing, not user interface components. User Interface components are covered under Success Criterion 4. 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. This requirement applies to web content that interprets pointer actions i.
For functionality that can be operated using a single pointer , at least one of the following is true:. For user interface components with labels that include text or images of text , the name contains the text that is presented visually. 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:.
The size of the target for pointer inputs is at least 44 by 44 CSS pixels except when:. 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.
The default human language of each Web page can be programmatically determined. 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.
A mechanism is available for identifying specific definitions of words or phrases used in an unusual or restricted way , including idioms and jargon. A mechanism for identifying the expanded form or meaning of abbreviations is available.
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.
A mechanism is available for identifying specific pronunciation of words where meaning of the words, in context, is ambiguous without knowing the pronunciation. When any user interface component receives focus, it does not initiate a change of context.
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. 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.
Components that have the same functionality within a set of Web pages are identified consistently. Changes of context are initiated only by user request or a mechanism is available to turn off such changes.
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. Labels or instructions are provided when content requires user input. 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.
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:.
Context-sensitive help is available. For Web pages that require the user to submit information, at least one of the following is true:. Content must be robust enough that it can be interpreted by by a wide variety of user agents, including assistive technologies.
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. 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.
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.
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. 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.
This section lists requirements for conformance to WCAG 2. It also gives information about how to make conformance claims, which are optional. Finally, it describes what it means to be accessibility supported , since only accessibility-supported ways of using technologies can be relied upon for conformance. Understanding Conformance includes further explanation of the accessibility-supported concept. The main content of WCAG 2.
Introductory material, appendices, sections marked as “non-normative”, diagrams, examples, and notes are informative non-normative. Non-normative material provides advisory information to help interpret the guidelines but does not create requirements that impact a conformance claim.
Although conformance can only be achieved at the stated levels, authors are encouraged to report in their claim any progress toward meeting success criteria from all levels beyond the achieved level of conformance. Conformance and conformance level is for full Web page s only, and cannot be achieved if part of a Web page is excluded. For the purpose of determining conformance, alternatives to part of a page’s content are considered part of the page when the alternatives can be obtained directly from the page, e.
Authors of Web pages that cannot conform due to content outside of the author’s control may consider a Statement of Partial Conformance.
New A full page includes each variation of the page that is automatically presented by the page for various screen sizes e. Each of these variations needs to conform or needs to have a conforming alternate version in order for the entire page to conform.
When a Web page is one of a series of Web pages presenting a process i. Conformance is not possible at a particular level if any page in the process does not conform at that level or better. An online store has a series of pages that are used to select and purchase products. All pages in the series from start to finish checkout conform in order for any page that is part of the process to conform.
Only accessibility-supported ways of using technologies are relied upon to satisfy the success criteria. Any information or functionality that is provided in a way that is not accessibility supported is also available in a way that is accessibility supported. See Understanding accessibility support. If technologies are used in a way that is not accessibility supported , or if they are used in a non-conforming way, then they do not block the ability of users to access the rest of the page.
In addition, the Web page as a whole continues to meet the conformance requirements under each of the following conditions:. In addition, the following success criteria apply to all content on the page, including content that is not otherwise relied upon to meet conformance, because failure to meet them could interfere with any use of the page:.
If a page cannot conform for example, a conformance test page or an example page , it cannot be included in the scope of conformance or in a conformance claim. For more information, including examples, see Understanding Conformance Requirements. Conformance is defined only for Web pages. However, a conformance claim may be made to cover one page, a series of pages, or multiple related Web pages. Conformance claims are not required. Authors can conform to WCAG 2.
However, if a conformance claim is made, then the conformance claim must include the following information:. A concise description of the Web pages , such as a list of URIs for which the claim is made, including whether subdomains are included in the claim.
The Web pages may be described by list or by an expression that describes all of the URIs included in the claim. Web-based products that do not have a URI prior to installation on the customer’s Web site may have a statement that the product would conform when installed. If a conformance logo is used, it would constitute a claim and must be accompanied by the required components of a conformance claim listed above. In addition to the required components of a conformance claim above, consider providing additional information to assist users.
Recommended additional information includes:. Refer to Understanding Conformance Claims for more information and example conformance claims. Refer to Understanding Metadata for more information about the use of metadata in conformance claims. Sometimes, Web pages are created that will later have additional content added to them. For example, an email program, a blog, an article that allows users to add comments, or applications supporting user-contributed content.
Another example would be a page, such as a portal or news site, composed of content aggregated from multiple contributors, or sites that automatically insert content from other sources over time, such as when advertisements are inserted dynamically.
In these cases, it is not possible to know at the time of original posting what the uncontrolled content of the pages will be. It is important to note that the uncontrolled content can affect the accessibility of the controlled content as well.
Two options are available:. A determination of conformance can be made based on best knowledge. If a page of this type is monitored and repaired non-conforming content is removed or brought into conformance within two business days, then a determination or claim of conformance can be made since, except for errors in externally contributed content which are corrected or removed when encountered, the page conforms. No conformance claim can be made if it is not possible to monitor or correct non-conforming content;.
A “statement of partial conformance” may be made that the page does not conform, but could conform if certain parts were removed. A “statement of partial conformance due to language” may be made when the page does not conform, but would conform if accessibility support existed for all of the language s used on the page. Some companies have adopted what used to be an initialism as their company name. In these cases, the new name of the company is the letters for example, Ecma and the word is no longer considered an abbreviation.
To qualify as an accessibility-supported use of a Web content technology or feature of a technology , both 1 and 2 must be satisfied for a Web content technology or feature :. The way that the Web content technology is used must be supported by users’ assistive technology AT. This means that the way that the technology is used has been tested for interoperability with users’ assistive technology in the human language s of the content,.
The Web content technology must have accessibility-supported user agents that are available to users. This means that at least one of the following four statements is true:. The technology is supported in a widely-distributed plug-in that is also accessibility supported;. The content is available in a closed environment, such as a university or corporate network, where the user agent required by the technology and used by the organization is also accessibility supported;.
The user agent s that support the technology are accessibility supported and are available for download or purchase in a way that:. The WCAG Working group and the W3C do not specify which or how much support by assistive technologies there must be for a particular use of a Web technology in order for it to be classified as accessibility supported.
Web technologies can be used in ways that are not accessibility supported as long as they are not relied upon and the page as a whole meets the conformance requirements, including Conformance Criterion 4 and Conformance Criterion 5 , are met.
When a Web Technology is used in a way that is “accessibility supported,” it does not imply that the entire technology or all uses of the technology are supported. Most technologies, including HTML, lack support for at least one feature or use. When citing Web content technologies that have multiple versions, the version s supported should be specified. One way for authors to locate uses of a technology that are accessibility supported would be to consult compilations of uses that are documented to be accessibility supported.
Authors, companies, technology vendors, or others may document accessibility-supported ways of using Web content technologies. However, all ways of using technologies in the documentation would need to meet the definition of accessibility-supported Web content technologies above.
A screenplay used to create the synchronized media content would meet this definition only if it was corrected to accurately represent the final synchronized media after editing. The word guava in the following sentence “One of the notable exports is guava” is a link. The link could lead to a definition of guava, a chart listing the quantity of guava exported or a photograph of people harvesting guava.
Until the link is activated, all readers are unsure and the person with a disability is not at any disadvantage. Assistive technologies often communicate data and messages with mainstream user agents by using and monitoring APIs. The distinction between mainstream user agents and assistive technologies is not absolute. Many mainstream user agents provide some features to assist individuals with disabilities.
The basic difference is that mainstream user agents target broad and diverse audiences that usually include people with and without disabilities. Assistive technologies target narrowly defined populations of users with specific disabilities. The assistance provided by an assistive technology is more specific and appropriate to the needs of its target users.
The mainstream user agent may provide important functionality to assistive technologies like retrieving Web content from program objects or parsing markup into identifiable bundles. Assistive technologies that are important in the context of this document include the following:.
Audio can be created synthetically including speech synthesis , recorded from real world sounds, or both. Audio description of video provides information about actions, characters, scene changes, on-screen text, and other visual content.
In standard audio description, narration is added during existing pauses in dialogue. See also extended audio description. Where all of the video information is already provided in existing audio , no additional audio description is necessary.
See also flash. It is possible for something to be large enough and blink brightly enough at the right frequency to be also classified as a flash. A Turing test is any system of tests designed to differentiate a human from a computer.
It is named after famed computer scientist Alan Turing. The term was coined by researchers at Carnegie Mellon University. Captions are similar to dialogue-only subtitles except captions convey not only the content of spoken dialogue, but also equivalents for non-dialogue audio information needed to understand the program content, including sound effects, music, laughter, speaker identification and location.
Open Captions are any captions that cannot be turned off. For example, if the captions are visual equivalent images of text embedded in video. Audio descriptions can be, but do not need to be, captioned since they are descriptions of information that is already presented visually.
A change of content is not always a change of context. Changes in content, such as an expanding outline, dynamic menu, or a tab control do not necessarily change the context, unless they also change one of the above e.
Opening a new window, moving focus to a different component, going to a new page including anything that would look to a user as if they had moved to a new page or significantly re-arranging the content of a page are examples of changes of context.
In this definition, “can only be reached” means that there is some mechanism, such as a conditional redirect, that prevents a user from “reaching” loading the non-conforming page unless the user had just come from the conforming version. The alternate version does not need to be matched page for page with the original e. If multiple language versions are available, then conforming alternate versions are required for each language offered.
Alternate versions may be provided to accommodate different technology environments or user groups. Each version should be as conformant as possible. One version would need to be fully conformant in order to meet conformance requirement 1. The conforming alternative version does not need to reside within the scope of conformance, or even on the same Web site, as long as it is as freely available as the non-conforming version.
Alternate versions should not be confused with supplementary content , which support the original page and enhance comprehension. Setting user preferences within the content to produce a conforming version is an acceptable mechanism for reaching another version as long as the method used to set the preferences is accessibility supported. See Understanding Conforming Alternate Versions.
Because authors do not have control over user settings as to how text is rendered for example font smoothing or anti-aliasing , the contrast ratio for text can be evaluated with anti-aliasing turned off.
For the purpose of Success Criteria 1. If no background color is specified, then white is assumed. Background color is the specified color of content over which the text is to be rendered in normal usage. It is a failure if no background color is specified when the text color is specified, because the user’s default background color is unknown and cannot be evaluated for sufficient contrast.
For the same reason, it is a failure if no text color is specified when a background color is specified. When there is a border around the letter, the border can add contrast and would be used in calculating the contrast between the letter and its background. A narrow border around the letter would be used as the letter. A wide border around the letter that fills in the inner details of the letters acts as a halo and would be considered background.
WCAG conformance should be evaluated for color pairs specified in the content that an author would expect to appear adjacent in typical presentation. Authors need not consider unusual presentations, such as color changes made by the user agent, except where caused by authors’ code. This unit is density-independent, and distinct from actual hardware pixels present in a display.
User agents and operating systems should ensure that a CSS pixel is set as closely as possible to the CSS Values and Units Module Level 3 reference pixel [ css3-values ], which takes into account the physical dimensions of the display and the assumed viewing distance factors that cannot be determined by content authors.
The down-event may have different names on different platforms, such as “touchstart” or “mousedown”. See general flash and red flash thresholds for information about types of flash that are not allowed. Exception: Flashing that is a fine, balanced, pattern such as white noise or an alternating checkerboard pattern with “squares” smaller than 0.
For general software or Web content, using a x pixel rectangle anywhere on the displayed screen area when the content is viewed at x pixels will provide a good estimate of a 10 degree visual field for standard screen sizes and viewing distances e.
Higher resolutions displays showing the same rendering of the content yield smaller and safer images so it is lower resolutions that are used to define the thresholds.
A flash consists of two opposing transitions. Tools are available that will carry out analysis from video screen capture. However, no tool is necessary to evaluate for this condition if flashing is less than or equal to 3 flashes in any one second. Content automatically passes see 1 and 2 above.

Fonts with extraordinarily thin strokes or unusual features and characteristics that reduce the familiarity of their letter forms are harder to read, especially at lower contrast levels.
