The 3 ranks of
Website Accessibility

Rank A includes the basic recommendations for accessible web content and is the minimum requirement for most websites. Some examples of Rank A recommendations include:

• Alternative text for images: Images should have alternative text describing what is in the image for users who cannot see the image.
• Headings: use a clear hierarchy of headings to structure the content and make it more understandable for all users.
• Color contrast: The contrast between text and background should be sufficient so that users can easily read the text.

Rank AA includes all Rank A recommendations plus additional recommendations to improve accessibility. Some examples of rank AA recommendations include:

• Subtitles: If there is video content on a website, it should be captioned to make it accessible to hearing impaired users.
• Keyboard operability: all functions on the website should also be operable with the keyboard so that users who cannot use a mouse can navigate the website easily.
• Text coloring: The coloring of texts should be designed so that they can be easily read by users with color vision impairments.

Website Accessibility

Rank AAA includes all recommendations from Ranks A and AA, plus additional recommendations to achieve the highest level of accessibility. Some examples of recommendations at Rank AAA are:

• Sign language: if there is video content on a website, it should also be available in sign language to make it accessible to deaf users.
• Text resizing: all text should be easily enlarged or reduced to make it easier for users with visual impairments to read.
• Error tolerance: A website should be designed in such a way that if errors occur, they are clearly indicated and a solution is provided. In the best case, however, potential errors should be prevented in advance.

Rank AAA is the highest level of accessibility and ensures that websites are accessible to all users, regardless of their limitations. It is important to note, however, that it is not always possible to meet all the recommendations of rank AAA. However, in such cases, companies should provide alternative ways to ensure the accessibility of their website.
