Hi, Kent.
We definitely invested in accessibility, but we don’t claim any specific level. Basically, it’s better than it was.
You might want to run an accessibility checker likeĀ http://wave.webaim.org/ or alternatives for our demo site–wpshindig.com–and see if things are up to your requirements.
Last but not least, we have a pretty great Refund Policy so you can buy one or many of our add-ons and thoroughly test them.
I hope this info helps. Let me know if you have any follow-up questions.
