This past September marked the first time a judge ruled that the ADA applies even to businesses without a physical location. Scribd, an e-book subscription service is considered to provide "a place of public accommodation." Their services are not accessible to blind persons because they cannot be read with a screen reader. The judge reasoned, "Now that the Internet plays such a critical role in the personal and professional lives of Americans, excluding disabled persons from access to covered entities that use it as their principal means of reaching the public would defeat the purpose of this important civil rights legislation."
Both sites include hidden same-page links at the top of the page for skipping to particular content. The CDC site includes five of these links, roughly corresponding with each of the landmark regions. These links become visible when keyboard users tab into the page. These links may ultimately be unnecessary if browsers support navigation by headings or landmarks. Screen readers already provide this support, but until browsers do so natively, non-mousers with eyesight can benefit from skip links like the ones on these government sites.
Title III of the Americans with Disabilities Act (ADA) requires that businesses and nonprofit services providers make accessibility accommodations to enable the disabled public to access the same services as clients who are not disabled. This includes electronic media and web sites. While the ADA applies to businesses with 15 or more employees, even smaller businesses can benefit from ensuring that their websites are ADA compliant. Doing so opens your company up to more potential clients and limits liability. Web developers should include ADA compliant features in the original site and application plans.
