a11y

a11y can be used by Web developers while they're coding their Web projects, or even after, allowing them to check what accessibility standards they're currently breaking.

This tool works via the Node.js command-line terminal, but developers have also altered it to work as a Web service or Grunt.js task.

a11y closely follows the WAI-ARIA guidelines, providing insightful clues on how to optimize or modify a website's code to support various features that help users with disabilities read and navigate your content.

WAI-ARIA itself is not a standard, but supporting it broadens a website's appeal and opens it to a bigger userbase.

Installing a11y is simple, just like any other Node.js global command:

npm install -g a11y

Requirements:

• Node.js 0.10 or higher
