Images and Alternative Text
- Alternative (alt) text is required to provide a textual alternative to non-text content in web pages.
-
This text will be read aloud to a person using a screen reader. Some Examples:
Jaws Screen Reader
Apple VoiceOver Links to an external site. (OS X)
ChromeVox Links to an external site. (Google Chrome)
- By default, Canvas includes the image name as the alt text, which should be changed to something more descriptive when embedding images.
-
Clean and simple design: eliminate the irrelevant. No graphics for the sake of decorations.
- Make sure images are labeled for reuse before adding them to your course.
Example Image:
Default Alt Text (name of image): kids-tech-revised.jpg
Modified Alt Text: one boy and two girls sitting on a couch with a smartphone, tablet, and laptop.
Other considerations: Content that flashes at certain rates or patterns can cause photo-sensitive reactions, including seizures.
