Other forms of perception are covered in Guideline 1.3 including programmatic access to color and other visual presentation coding. | Product has been developed to conform to this standard subject to the remarks on the right. | The product was tested for - Information conveyed by color is available in alternative formats, such as shape, text, font weight
- Information is not conveyed using color
|
1.4.2 Audio Control: 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. (Level A)
Note: 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. | Product has been developed to conform to this standard subject to the remarks on the right. | There is no Audio provided on the web page (Dashboard reports). |

Note: Logotypes (text that is part of a logo or brand name) are considered essential. | Product has been developed to conform to this standard subject to the remarks on the right. | The product was tested for - Images of text are only used when the technology can't create the desired visual presentation, the image can be customized or the particular image is essential. These are used in texts used within the graphs.
|
2.1.1 Keyboard: 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. (Level A)
Note 1: 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.
Note 2: This does not forbid and should not discourage providing mouse input or other input methods in addition to keyboard operation. | Product has been developed to conform to this standard subject to the remarks on the right. | The product was tested for: - Ability to perform functions from the keyboard only, and without requiring specific timings for individual keystrokes
Bug 20388243 - The functional Hyper links provided in the online reports are not accessible though keyboard. |
2.1.2 No Keyboard Trap: 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. (Level A)
Note: 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. See Conformance Requirement 5: Non-Interference. | Product has been developed to conform to this standard subject to the remarks on the right. | The product was tested for: - Movement of focus through each control only using the keyboard, with no "keyboard trap" that prevents focus from moving away from any control
|
2.2.1 Timing Adjustable: For each time limit that is set by the content, at least one of the following is true: (Level A)
- 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 Success Criterion 3.2.1, which puts limits on changes of content or context as a result of user action. | Product has been developed to conform to this standard subject to the remarks on the right. | The product was tested for - Time limits in the product can be turned off before they are encountered
- Time limits in the product can be adjusted to at least 10 times longer before encountered

|
2.2.2 Pause, Stop, Hide: For moving, blinking, scrolling, or auto-updating information, all of the following are true: (Level A)
- 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.
Note 1: For requirements related to flickering or flashing content, refer to Guideline 2.3.
Note 2: 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. See Conformance Requirement 5: Non-Interference.
Note 3: 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.
Note 4: 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. | Product has been developed to conform to this standard subject to the remarks on the right. | The product was tested for - Moving, blinking, or scrolling information that is designed to last for more than five seconds can be paused
- Moving, blinking, or scrolling content that is pure decoration can be stopped or hidden
