No accessibility annotations are needed for file uploaders, but keep these considerations in mind if you are modifying Carbon or creating a custom component.
What Carbon provides
Carbon bakes keyboard operation into its components, improving the experience of blind users and others who operate via the keyboard. Carbon incorporates many other accessibility considerations, some of which are described below.
Both variants of the file uploader provide buttons for uploading and removing
files. The drop target “Drag and drop files here…” also provides conventional
button keyboard interaction (
Tab to reach;
Space to activate).
Once a file has been added, it can be removed by activating the delete (“x”)
button after each file name.
Keep these considerations in mind if you are modifying Carbon or creating a custom component:
- The ‘Drag files’ area is constructed as a button to support keyboard operation.
- Error messages about file uploads must be exposed to assistive technology.
- The Delete button needs to have the uploaded file name associated with it programmatically, so the user understands which file will be removed.
