This is the exact opposite of mistake #1. Let me start by revealing a dirty little secret when it comes to website design. Most people think, Oh, I’m going to hire a professional website firm because I want a “real website” As opposed to a Word Press website or something else. And what most people don't realize is that all websites are made from the same stuff.
HTML tags – specific instructions understood by a web browser or screen reader. One type of HTML tag, called an “alt” tag (short for “alternative text”), is used to provide brief text descriptions of images that screen readers can understand and speak. Another type of HTML tag, called a “longdesc” tag (short for “long description”), is used to provide long text descriptions that can be spoken by screen readers.
As I mentioned above, under each WCAG 2.1 principle is a list of guidelines, and under each guideline are compliance standards, with techniques and failure examples at each level. Some guidelines include only Level A items; others include items for multiple levels of conformance, building from A to AAA. At each stage, you can easily see what more you would need to do to reach Level AA or AAA. In this way, many websites include elements at multiple levels of accessibility.
The Americans with Disabilities Act was instituted in 1990 in an effort to end discrimination based on differing abilities. Drawing heavily from the landmark Civil Rights Act of 1964, which established protections against discrimination based on race, religion, sex or national origin, the ADA went a step further by requiring organizations to provide “reasonable accommodations” to employees with disabilities.
Web designers often design in such a way that does not allow the user to adjust font size or color. While they may be protecting their brand, they are also inhibiting some users. Many visually impaired need to use high contrast color settings or very large fonts to read a website. Don't design your website in a way that makes it impossible for them to do this.
While the impact of the Americans with Disabilities Act on online accessibility is likely to remain vague for the foreseeable future, there is no question that equal access is a major concern for users across America, and for the courts that serve those users. In lieu of a clear set of national guidelines, abiding by WCAG accessibility standards remains the best option for most organizations. It’s not just a smart way to avoid accessibility lawsuits and negative publicity—providing accessible solutions for all users is just the right thing to do.
