axe-core Rule URL Pattern

text

Base URL: https://dequeuniversity.com/rules/axe/4.10/
Pattern:  {base_url}{rule-id}
Example:  https://dequeuniversity.com/rules/axe/4.10/image-alt

For any axe-core rule, construct the URL by appending the rule ID to the base URL. This pattern covers all axe-core rules.
