A. Text and Media Accessibility

1. Text Alternatives for Non-Text Content
Provide descriptive text alternatives for all non-text content, such as images, charts, and infographics. These alternatives should be comprehensive enough to convey the same information as the visual content and can be transformed into formats like large print, braille, speech, or symbols. It is important to note that this requirement does not extend to decorative images that do not hold informative value.

2. Alternatives for Video and Audio Content
Ensure that video-only and audio-only content is accompanied by alternative formats. This could include providing transcripts for audio files and audio descriptions for videos, making the information accessible to users who are deaf, hard of hearing, blind, or have low vision.

3. Captions for Audio in Videos
All videos that contain audio must have synchronized captions. Captions should accurately reflect spoken dialogue as well as important non-verbal sounds (e.g., music cues and sound effects) to ensure that users who are deaf or hard of hearing can fully engage with the content.

B. Visual Presentation and Interaction

4. Color Contrast and Visual Indicators
Ensure that any critical information conveyed through color is also available through other visual means, such as text labels or patterns. This is essential for users with color blindness or visual impairments to access the information effectively.

5. Control Over Auto-Playing Content
Provide users with the ability to control auto-playing media on your website. Auto-playing content can disrupt screen readers and create a frustrating experience for users. If feasible, consider disabling auto-play entirely to improve accessibility.

6. Keyboard Navigation
Guarantee that all website functionalities can be accessed and operated using a keyboard alone. This is crucial for users with mobility impairments who may not be able to use a mouse, ensuring they can navigate your site effectively.

7. Time Limit Control
Allow users to manage time limits when interacting with time-sensitive content. Users should have the option to request additional time without losing any entered data or session progress, accommodating those who may need more time to read or respond.

8. Seizure-Inducing Content Prevention
Design web pages that do not include content capable of inducing seizures, such as flashing elements that blink more than three times per second. This is particularly important for individuals with photosensitive epilepsy.

9. Customizable Single-Key Shortcuts
Ensure that single-key shortcuts used on your website can be disabled or modified by users. This flexibility helps prevent accidental activation of shortcuts that may interfere with navigation.

C. User Experience Enhancements

10. “Skip to Content” Link
Implement a “Skip to Content” link at the top of your web pages, allowing users to bypass repetitive navigation links and jump directly to the main content area. This feature enhances the browsing experience for users who rely on keyboard navigation.

11. Error Identification and Description
If a user makes an error while filling out forms or interacting with the site, provide clear text descriptions of the error and how to resolve it. Simply highlighting a field in red is insufficient; detailed instructions should guide users in correcting their input.

12. Clear and Helpful Web Page Titles
Ensure that each web page has a clear and descriptive title that accurately reflects its content. This helps users understand what to expect when navigating through different pages and assists in improving overall site navigation.

13. Accessibility for Users with Limited Mobility
Confirm that all website functions can be performed by users with limited mobility. This includes ensuring that actions typically performed with a mouse can also be accomplished using keyboard shortcuts or alternative input devices.

14. Language Assignment for Web Pages
Assign the correct language attribute to each web page to assist screen readers and other assistive technologies in accurately interpreting the content. This is essential for users who rely on these technologies for comprehension.

15. Stability of Web Elements Upon Input
Ensure that web elements do not change unexpectedly when they receive input from users. This stability helps prevent confusion and enhances usability, particularly for individuals using assistive technologies.
