ACCESSIBILITY

When creating content, consider the needs of people with disabilities.

There is a good deal of information about creating web content for accessibility. One example of this is WebAIM's, Introduction to Web Accessibility.

Lessons has several features to help you create accessible content:

Images

Images should generally include an "ALT tag", a textual description of the image. However images that are there for decoration, to add blank space, etc., should generally have blank ALT tags.

After adding an image using "Add Multimedia", the "Edit" button will let you add ALT text.

If you insert an image in "Add Text", using the web editor, the "Image" dialog also makes provisions to supply ALT text.

Multimedia Content

When you use multimedia content, generally you should provide alternative ways of getting the content, at least some of which are appropriate for use with screen readers.

In Lessons there are several ways to provide alternative content. The simplest is to add a description underneath the content. After adding content with "Add Multimedia", the "Edit" button will let you add a description field under the content.

If a brief description isn't enough, consider using "Add Subpage" to create a page with more extensive alternative content, or using "Add Resource" to point to an existing resource.
