Executive Summary

This report describes the conformance of the Chess.com website with W3C’s Web Content Accessibility Guidelines (WCAG). The review process is described in Section 5 below and is based on evaluation described in Accessibility Evaluation Resources.

Based on this evaluation, the Chess.com website is not close to meeting WCAG 2.1, Conformance Level AA. Detailed review results are available in Section 6 below. Resources for follow-up study are listed in Section 7 below. Feedback on this evaluation is welcome.

Background about Evaluation

Conformance evaluation of web accessibility requires a combination of semi-automated evaluation tools and manual evaluation by an experienced reviewer. The evaluation results in this report are based on evaluation conducted on the following date(s): 4/5/22 - 4/9/22. The website may have changed since that time.

Review Process

Level A, AA WCAG 2.1 was tested.

The evaluation tools used were:

  1. ANDI Accessibility Testing Tool
  2. WAVE Web Accessibility Evaluation Tool

Manual testing was carried out when looking at context, hierarchy, and readability.

Results and Recommended Actions

47 Guidelines were tested for evaluation.

This website is not close to meeting WCAG 2.1 AA guidelines.

Chess.com excels in understandability, but it has many problems with missing headings, alt texts, and more.

Instructions for how to meet WCAG can be found here.

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

1.3.3 Sensory CharacteristicsLevel 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.

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

1.4.2 Audio ControlLevel 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.

1.4.3 Contrast (Minimum)Level AA The visual presentation of text and images of text has a contrast ratio of at least 4.5:1, except for the following:

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

2.1.1 KeyboardLevel AAll 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.

2.1.2 No Keyboard TrapLevel A 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.

2.2.2 Pause, Stop, HideLevel A

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

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; andAuto-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.

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

2.2.6 TimeoutsLevel AAA(Added in 2.1)

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.
