Serving content to diverse audiences
Double-A website conformance means a team has invested time and energy into upgrading their website. With affordances such as strong color contrast, video caption considerations, and robust integration with assistive technology, many organizations find double-a conformance to be a good balance between serving a wide range of users with a reasonable budget.
- Captions are present on live video.
- When appropriate, there exists audio description of what’s happening on streaming media.
- The user must be able to resize text without breaking layout.
- No images of text containing any more than incidental content (so no text banners).
- The language is declared in the head of the document.
- There exists a minimum contrast of 4.5:1 among elements.
- Heading tags (h1, h2, h3, etc.) are present and emerge from content organically.
- When an intractable element is present it receives a focus state when tabbing to access.
- UI elements common on the site have a unifying design.
- If an error is present on a form, the website will: suggest ways to fix it, the user may withdraw and resubmit the form, or the form prompts a confirmation.
- Pages can’t be nested or unintentionally obfuscated unless part of a step-by-step process, such as an application or feed result.
- Navigation follows a semantic structure and is repeated on pages.
