ideas, break them down into smaller, more manageable pieces. This helps users
better understand the information.
6.2 Providing Alt Text for Images
Alt text, or alternative text, is a crucial element for
making images accessible. Alt text provides a text description of an image,
allowing users who cannot see the image to understand its content. Here's how
to make your images accessible:
- Write descriptive alt text: Describe the image using
concise and informative text. Be sure to convey the essential information the
- Avoid using redundant or generic alt text: Steer clear of
generic phrases like "image" or "picture." Instead, provide
meaningful descriptions that add value to the user's understanding of the
6.3 Ensuring Multimedia Accessibility: Captions and Transcripts
Multimedia elements like videos and audio can greatly
enhance your content, but they can also present barriers for users with
different abilities. Consider these tips to make your multimedia content
- Provide captions for videos: Captions allow users with
hearing impairments to access the audio content of videos. Use closed captions,
which users can toggle on and off as needed.
- Include transcripts for audio content: Transcripts serve
as a text-based alternative to audio content. They benefit users who are deaf
or hard of hearing as well as those who prefer to read instead of listening.
7. Inclusive Design for Different Abilities and Disabilities
