The menu is fully keyboard accessible and contrast levels for text are kept well above the 4.5:1. This theme passes WCAG 2.0 AA standards out-of-box. On wordpress.org, Period is given the “accessibility-ready” tag. This is basically a reminder to users that while all design elements in Period pass accessibility standards, it’s up to the user to make sure their content is accessible too in order for their site to maintain its accessibility.
Use the plugin, follow its instruction, and resolve the compliance issues identified. You’ll find that using the plugin will save you an incredible amount of time as you maintain your site’s compliance on a month-to-month basis. The best part, it identifies the compliance issues and tells you exactly which code elements are out of compliance and why! Our average customer is reporting a 10x-20x time savings over manually identifying and fixing these problems. In extreme cases more than 30x time savings has been reported! Using the plugin alone does not guarantee compliance. Some parts of accessibility can’t be automatically scanned and must be manually audited but we also provide independent 3rd-party audits and certifications of compliance. The Accessibility Suite Pro Plugin for WordPress makes this process profoundly easier.
