  },
});

Custom Options

In this example, you are testing the url against the WCAG2AAA standard.

grunt.initConfig({
  pa11y: {
    options: {
      url: 'google.com',
      standard: 'WCAG2AAA'
    }
  },
});

Multiple URLs

In this example, you are testing the multiple urls against the WCAG2AAA standard.

grunt.initConfig({
  pa11y: {
    options: {
      url: ['google.com', 'yahoo.com'],
      standard: 'WCAG2AAA'
    }
  },
