Overview of Accessibility Guidelines and ObservePoint's Solution
To ensure that web pages adhere to the Web Content Accessibility Guidelines (WCAG) standards, our application performs automatic checks on various HTML attributes.
The table below lists the different attributes that our system can automatically check for, along with descriptions of each. By identifying and addressing potential accessibility issues, our platform helps improve the user experience for individuals with disabilities.
WCAG - short for Web Content Accessibility Guidelines - is categorized into three levels of conformance to meet the needs of different groups and situations: A (lowest), AA (mid-range), and AAA (highest).
We support all levels of conformance with current versions of WCAG: 2.0, 2.1, and 2.2. Conformance at higher levels indicates conformance at lower levels. For example, a web page that conforms to AA meets both the A and AA conformance levels. Most organizations set their standards at level AA because it is both achievable and meaningful, without being too disruptive to the design and development process of a website.
Within each version and conformance level we also support four levels of severity:
Critical issues are accessibility problems that significantly hinder or completely block the ability of people with disabilities to access and use web content.
Serious issues are problems that significantly impact the usability of web content for people with disabilities, causing considerable inconvenience or difficulty without completely blocking access.
Moderate issues are problems that impact the usability of web content for people with disabilities, creating noticeable challenges that can be overcome with some effort.
Minor issues are problems that have a small impact on the usability of web content for people with disabilities, causing minor inconveniences or deviations from best practices without significantly hindering access
Most customers tell us they focus on WCAG 2.1 AA Critical and Serious Issues.
In addition to automated functional testing, which verifies that content functions as expected, usability testing is recommended to determine how well people can use the content for its intended purpose. It is recommended that users with disabilities be included in test groups when performing usability testing.
