As you create or review your content, or partner with a company to conduct accessibility testing, the following interactive WCAG checklist will serve as a helpful guide to applicable success criteria. The checklist includes all WCAG 2.2 success criteria (which include the 2.1 and 2.0 criteria).
Web pages
- Info and Relationships
Information and content relationships implied by formatting are communicated in text or in a way that works with assistive technology. - Meaningful Sequence
The reading order of content is meaningful, no matter how a user accesses or consumes it. - Sensory Characteristics
Instructions rely on more than one sense. - Use of Color
Color is not the only way used to distinguish an element, convey meaning, indicate an action, or prompt a response. - Page Title
Page titles clearly describe the page topic or page purpose. - Link Purpose (In Context)
The purpose of each link can be determined from the link text alone or from the link text and its related context. - Labels or Instructions
A persistent visible label and / or instructions are provided for elements that require user input. - Captions (Live)
Synchronized captions are provided for live videos containing audio. - Audio Description (Pre-recorded)
If there is important visual content in a video that is not presented in the accompanying audio, an audio description is provided. - Contrast (Minimum)
The contrast ratio between regular-sized, non-decorative text and its background is at least 4.5:1. - Non-Text Contrast
The contrast ratio between non-text elements (including any states) and their background is at least 3:1. - Text Spacing
Text spacing can be overridden to improve the reading experience. - Content on Hover Focus
When additional content is presented on hover or on focus, the new content is persistent and dismissable. - Multiple Ways
There is more than one way to reach each page. - Headings and Labels
Headings and labels are clear and descriptive. - Dragging Movements
If any part of a website requires a dragging movement, an alternative means of dragging, such as tapping or clicking, is provided. - Target Size (Minimum)
The size of a target is at least 24 by 24 CSS pixels (with exceptions). - Consistent Navigation
Navigational elements are consistently displayed, including their location and the order of their content. - Error Suggestion
Users receive helpful / specific suggestions when they make errors. - Error Prevention (Legal, Financial, Data)
When users enter financial or legal data, submissions are reversible, and data is checked and confirmed before submission is finalized. - Status Messages
Status messages can be presented to the user by assistive technology without receiving focus.
Images, video and audio elements
- Images of Text
Aside from a few specific exceptions, there are no images of text. - Non-text Content
Text alternatives are provided for non-text content such as images, videos, and audios. - Audio-only and Video-only (Pre-recorded)
A transcript is provided for audio-only content and a transcript or audio description is provided for video-only content. - Captions (Pre-recorded)
Captions are provided for video with audio. - Audio Description or Media Alternative (Pre-recorded)
A transcript and / or audio descriptions are provided for video with audio. - Audio Control
A mechanism is provided to control audio that plays on page automatically for more than three seconds. - Pause, Stop, Hide
