consistently. (Level AA)

Sufficient Techniques for 3.2.4 – Consistent Identification

  • 1.G197: Using labels, names, and text alternatives consistently for content

Sufficient Techniques for 3.2.3 – Consistent Navigation

  • 1.G61: Presenting repeated components in the same relative order each
    time they appear
