Sufficient Techniques

In the WCAG framework, sufficient techniques are documented methods for meeting a specific success criterion. If a content author correctly implements a sufficient technique, it is enough to satisfy the associated requirement. Multiple sufficient techniques may exist for a single success criterion, often organized by situation, giving developers different options depending on the technology or context. Sufficient techniques are distinguished from advisory techniques, which enhance accessibility but are not enough on their own to meet a success criterion, and from failures, which are documented practices that definitively violate a success criterion.
