Put quite simply, this means the content must be detectable to a user’s senses. Therefore, it’s key to present information that can be perceived in a variety of ways where a visitor can make changes to enlarge the size of font, changes to colour contrasts and caption videos.
This is all about making sure your users can comfortably navigate your site, navigation must be operable to users in ways they can operate. Therefore, required interactions can be performed using keyboard or voice commands and don’t restrict how long it takes someone to read a piece of content.
Users must be able to process the information in front of them and this covers for example, information and instructions are clear and navigation methods are easy to understand and use.
This covers the importance of thinking about the likely ways that technology could evolve. Therefore, content needs to be interpreted reliably by a wide variety of users and different assistive technologies. As a rule, if technology and the user change and develop the code and content should remain accessible.
What are the WCAG 2.1 levels of conformance ?
The WCAG 2.1 has three levels of conformance Levels, A, AA and AAA and each guideline has its own principle and success criteria.
Level A defines the lowest level of conformance, and Level AAA defines the highest level of conformance, which is the most difficult to achieve.
Currently, much web content is able to achieve Level A conformance thanks to awareness of basic techniques such as alt text, keyboard navigation and colour contrasts.
However, it is rare for content to meet even Level AA of conformance, and Level AAA conformance is exceptionally rare and difficult to meet. Many large businesses and government organisations around the world mandate for their content to meet Level AA conformance of WCAG 2.1.
