When it comes to a website, its actual value and reach are directly proportionate to its universality. It is accessible to everyone irrespective of their location, gender, age, ethnicity, and the difference in physical and cognitive abilities. It means universality mandates easy access to web content by people with disabilities too. Many of the websites and web applications are now meant for only people who have fit physically and cognitively. Many of the web designers and developers too are not keen on developing websites for easy access to disabled people.
For the awareness of website owners and web developers, we will discuss five of the biggest accessibility mistakes for you to avoid while building your website ADA compliant.
1. Noncompliant Colour Contrast
The text fond and the colour schema of the background should be synced well to make readable to all. Low contrast colour combinations may be a problem for those who have colour blindness or with impaired vision. It may also be a problem for older adults to read low contrast text vs. background combination. The same problem may be there for people with dyslexia and reading disabilities too.
The latest WCAG 2.0 (Web Content Accessibility Guidelines) recommendation by W3C mandates an ideal contrast ratio as 4.5:1 for regular text used for web content and 3:1 for larger font texts (the 14-point, bold, and large texts).
2. Insufficient Keyboard Access
All browsers may display a highly visible outline like a dotted line or a blue border around content with a keyboard focus. The users can see this on clicking the tab key while viewing a web page. Accessibility to the keyboard is an important mandate in web accessibility. There are many web users with motor neuron deficiencies. The screen magnification users with partial blindness also rely on the keyboard.
Compliant websites should allow users to access every content and features through the keyboard itself. It is noted that in some cases, the designers tend to disable these features for aesthetic reasons, which is a mistake. As https://siteimprove.com/en-us/accessibility/website-accessibility/ points out, ensure that the keyboard focus is clearly shown and it follows a logical order. Providing such a visual indication is mandatory to show the keyboard focus, but not following this properly may be another big mistake in terms of web accessibility.
3. Irrelevant Image Alt Text
People with poor eyesight tend to use screen readers. These are software which can converts text on the screen to speech. These readers may not be able to view a picture and describe it. So, it is important for the developers to provide a proper alt text for the picture which exactly represents the content of the picture.
Google also mandates proper alt text as an essential SEO ranking element. So, it is a mistake to put insufficient or inadequate alt text for images, which will not only violate website accessibility rules but also will adversely affect search engine optimization.
Things are changing with the new mandates of Americans with Disabilities Act, which specifies that all public access entities including websites and applications must be compliant with the ADA guidelines. These guidelines centre around the need for all websites to be easily accessible to people with disabilities too.
So, those who are with visually impaired, auditory problems, colour blindness all should be able to comprehend the web content easy for your website to qualify for Web Accessibility.
