Introduction

The four principles of web accessibility for website content as specified in W3C are:

"Perceivable - Information and user interface components must be presentable to users in ways they can perceive.

This means that users must be able to perceive the information being presented (it can't be invisible to all of their senses).
Operable - User interface components and navigation must be operable.

This means that users must be able to operate the interface (the interface cannot require interaction that a user cannot perform).
Understandable - Information and the operation of user interface must be understandable.

This means that users must be able to understand the information as well as the operation of the user interface (the content or operation cannot be beyond their understanding).
Robust - Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies.

This means that users must be able to access the content as technologies advance (as technologies and user agents evolve, the content should remain accessible).

If any of these are not true, users with disabilities will not be able to use the Web.”

For more information, see the external guide:

Understanding the four principles of Accessibility.

Monsido prioritizes the results of the accessibility checks and places any issues in the following categories:

Error
The issue is in direct conflict with the standard and needs to be fixed.
Warning
The issue is most likely in conflict with the standard, do a manual review and fix the issue.
Review
The issue cannot be programatically determined as an error or warning and requires human review . Do a manual review of the issue to determine if any fix can be done.

For more information, see the User Guide chapter:

Priority, Severity, Difficulty, and Likelihood.
