The number input React Carbon component has been tested against the latest W3C Web Content Accessibility Guidelines (WCAG) 2.1 Level A and AA success criteria and violations have been identified as high priority issues. This document will be updated when these accessibility issues are resolved.
The number input components are form fields that are provided for user input of numerical data. The validation message should be included to advise the user of numbers that are input incorrectly or a required field that is missing. The optional helper text should be used to provide instructions to help users understand how to complete the numeric field as well as indicate any required and optional input, data formats, and other relevant information.
- Provide labels and instructions that are clear and concise.
- Provide instructions for completing the field. For example, Passwords must contain at least 8 letters and/or numbers.
- If the number input is a required field include the aria-required property and indicate that it is a required field and use the validation message for input errors.
