Is Drupal ADA Compliance ?

Hi guys,

Working in one project here I just got some questions that I did not have a clear answer and can’t find it on the community.

  • Is Drupal 7 ADA Compliance ?
  • Is it or are there issues we should be aware of?
  • What is the better tool to check ADA Compliance on the Website ?
  • Is there a list of issues with compliance available somewhere?
  • Where could I found more information regarding the ADA Compliance in Drupal?
Drupal version:
