According to the DOJ, “Being unable to access websites puts individuals with disabilities at a great disadvantage in today’s society.” With these words in mind, the DOJ has rapidly adopted the role of web accessibility enforcer. A failure to make digital content, including websites, accessible to all individuals regardless of their emotional, physical, or mental disabilities, can result in hefty fines and class action lawsuits. In short, the DOJ is dedicated to making sure that individuals with disabilities have the same equal access to the benefits that are available online. Creating equal access is only possible if organizations a) understand the requirements of web accessibility, b) know that web accessibility is an obligation under the ADA, and c) make web accessibility a priority. The value that awaits when organizations adhere to digital accessibility laws can be measured in more than dollars and cents.
Although the plugin works, we activated the white label solution. They said: For only $10 you can modify the widget footer, remove the donate link and enable other customizations From then and on they charge me every single month 10$, they don't reply to my messages and the so called "Manage" menu has been disappeared from the widget... BE AWARE! I'm still trying to resolve this....
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.
“The idea of equal access, equal opportunity has sort of evolved in its application from brick and mortar to eCommerce. At first, many companies were worried about the desktop experience. Now, the concern extends to both smart phones and devices.  Wherever a consumer accesses your content – whether it be directly through the web or an app – you need to be concerned about accessibility.”
Level AA is a little more significant, and makes sites accessible to people with a wider range of disabilities, including the most common barriers to use. It won't impact the look and feel of the site as much as Level AAA compliance, though it does include guidance on color contrast and error identification. Most businesses should be aiming for Level AA conformity, and it appears to reflect the level of accessibility the DOJ expects. 
President George H.W. Bush signed the Americans with Disabilities Act into law July 26, 1990. The ADA prohibits discrimination of people with disabilities and guarantees the same opportunities as everyone else. These opportunities include employment possibilities, purchasing of goods and services and the ability to participate in State and local government programs.
