Introduction to Accessibility Insights

The Accessibility Insights extension for Chrome is a tool that helps developers and designers test the accessibility of their web applications. The extension is designed to work with the Accessibility Insights for Web tool, which is a suite of automated and manual accessibility testing tools that can be used to identify accessibility issues in web applications.

An important aspect of accessibility insights is the use of design patterns that are known to improve accessibility. These patterns can include things like clear and consistent navigation, descriptive and meaningful link text, and the use of color contrast ratios that make it easy for people with visual impairments to read text.

Why Does Accessibility Insights Matter?

Accessibility insights can also help you avoid legal issues. In many countries, digital products and services must comply with accessibility laws and regulations. Failure to comply with these regulations can result in legal penalties and damage to a brand’s reputation.

Important Rules While Performing Heading Level Testing

  1. Follow the guidelines: The guidelines for heading levels should be followed strictly while performing testing. Typically, H1 is reserved for the main heading of the page or section, while H2 is used for subheadings, H3 for sub-subheadings, and so on. On all the pages there should be at least one heading.
  2. Test for consistency: Check whether the heading levels are consistent throughout the page or section. Inconsistent heading levels can confuse users and harm the page’s accessibility and usability.
