- Adding alternative text to images is one of the easiest accessibility principles to learn and one of the hardest to master.
- Alternative text may be provided in the
alt
attribute or in the surrounding context of the image. - Every image must have an
alt
attribute. - Alternative text should:
- present the CONTENT and FUNCTION of the image.
- be succinct.
- Alternative text should not:
- be redundant (be the same as adjacent or body text).
- use the phrases "image of…" or "graphic of…".
- Appropriate alternative text depends heavily on the image's context.
- Alt text of a functional image (e.g., an image within a link) should describe the function as well as the content.
- Decorative images still need an
alt
attribute, but it should be null (alt=""
).
