Guidelines for Effective Alt Text:
Be descriptive and concise.
Convey the purpose and context of the image.
Avoid redundancy with the surrounding text.
Include important details, such as text within the image.
Examples of Well-Crafted Alt Text:
- Image of a Guide Dog: Alt text – “A guide dog assisting its owner across the street.”
- Graph Illustrating Growth: Alt text – “Bar graph depicting significant growth in the past quarter.” Did you know about VPAT and its Importance?
2. Proper Heading Structure
Importance of a Clear Heading Hierarchy:
A well-structured heading hierarchy aids in organizing content, enhancing both visual and screen reader navigation.
Tips for an Organized Heading Structure
- Use headings in a logical order (H1, H2, H3, etc.).
- Ensure each heading accurately represents the content beneath.
- Avoid skipping heading levels.
Demonstrating Screen Reader Interpretation:
Screen readers use heading structures to create a table of contents for users. Consistent and meaningful headings contribute to a seamless reading experience.
3. Keyboard Navigation
