Why should every image include an alt attribute in HTML?
Asked on Sep 14, 2025
Answer
Every image should include an
alt attribute in HTML to provide alternative text for users who cannot see the image. This is crucial for accessibility, as it helps screen readers convey the content of the image to visually impaired users, and it also aids in SEO by allowing search engines to understand the image content.
Example Concept: The alt attribute in an <img> tag provides a textual description of the image. This description is used by screen readers to assist visually impaired users and is displayed if the image fails to load. It also helps search engines index the image content effectively.
Additional Comment:
- Always include meaningful and concise descriptions in the
altattribute. - If an image is purely decorative, use an empty
alt=""to indicate it should be ignored by screen readers. - Well-written
alttext improves the overall accessibility of your web pages.
