What are Web Accessibility Issues and How to Addressed by Web Developers ?
Last Updated : 24 Jul, 2024
Web accessibility allows individuals with disabilities, including those who are visually impaired, hearing-impaired, have mobility issues, or cognitive impairments to use the internet. Accessibility issues can adversely affect their ability to connect online.
Importance of Web Accessibility:
The ability to access websites is an essential right for everyone, including those living with disabilities. This includes people with impaired vision, hearing difficulties, mobility issues, and cognitive impairments. Accessibility issues can create serious impediments to the online presence of disabled users, preventing them from accessing sites. The importance of internet accessibility is recognized legally by the Americans with Disabilities Act (ADA) which states that all public businesses must provide a website open to disabled customers. Furthermore, research has shown that providing an accessible website raises customer satisfaction and improves the client base. Thus, it is vital for everybody to have the capacity to interact with the digital landscape.
Website Accessibility Checklist:
- Avoid utilizing jargon or technical terms not comprehensible to everyone.
- Using high-contrast colors helps people with visual impairments see content
- Use alt text to provide alternative descriptions for images, which is valuable for those unable to view them.
- Ensure keyboard accessibility
- Utilize semantic markup, making your site more understandable to assistive technology.
- After completion, test all changes with assistive tech to ensure accessibility.
Accessibility in Web Design Considerations:
When developing a website, here are some key points for attention:
- Secure a comprehensive structure.
- Label sections clearly through the use of headings.
- Choose a language that is lucid yet concise.
- Voice clear, contrasting color palettes.
- Abstain from pictures without supplying them alt texts.
- Permanent easement of the keyboard usability.
- Test out the site utilizing assistive technologies for true confirmation of accessibility.
Common web accessibility issues:
1. Inaccessible Images and Videos: Images and videos that lack proper alternative text can be inaccessible to people who use screen readers or other assistive technologies. Without alternative text, screen readers cannot describe the content to users with visual impairments. Additionally, videos that lack captions or transcripts can be inaccessible to people with hearing impairments.
Example:
HTML <!DOCTYPE html> <html> <head> <title>My Page</title> <style> .image { height: 40%; width: 100px; } </style> </head> <body> <header> <h1>My Website</h1> <nav> <ul> <li><a href="#">Home</a></li> <li><a href="#">About</a></li> <li><a href="#">Contact</a></li> </ul> </nav> </header> <main> <h2>My Content</h2> <p>This is some content.</p> <img class="image" src= "https://media.geeksforgeeks.org/img-practice/banner/devops-live-thumbnail.png?v=19438" alt="A description of the image"> </main> <footer> <p>© My Website</p> </footer> </body> </html> Output:

Non-descriptive link text: Links that use vague or non-descriptive text like "Click here" or "Read more" can be confusing to users with assistive technologies. Users rely on the link text to understand where the link will take them, so it's important to use descriptive text that accurately reflects the link's destination.
Example:
HTML <!DOCTYPE html> <html> <head> <title>My Page</title> </head> <body> <nav> <ul> <li><a href="#">Home</a></li> <li><a href="#">About Us</a></li> <li><a href="#">Contact Information</a></li> </ul> </nav> <main> <h2>Welcome to My Page</h2> <p>This is my page. Check out our <a href="#">products</a> and <a href="#">services</a>. </p> </main> <footer> <p>© My Page</p> </footer> </body> </html>
Output:

Inaccessible forms: Forms that lack proper labels or are not designed to be accessible with keyboard-only navigation can be challenging for users with motor impairments. Properly labeled form fields are critical for users who rely on assistive technologies to understand the purpose of each field.
Example:
HTML <!DOCTYPE html> <html> <head> <title>Contact Us</title> </head> <body> <form> <label for="name">Name:</label> <input type="text" id="name" name="name"><br> <label for="email">Email:</label> <input type="email" id="email" name="email"><br> <label for="message">Message:</label> <textarea id="message" name="message"></textarea><br> <button type="submit">Submit</button> </form> </body> </html>
Output:
4. Non-responsive web design: Websites that are not designed to be responsive to different screen sizes and resolutions can be difficult to use for people with disabilities. Web developers should use responsive design techniques to ensure that websites can be accessed and used on different devices, including smartphones and tablets.
Example:
HTML <!DOCTYPE html> <html> <head> <meta name="viewport" content= "width=device-width, initial-scale=1.0"> <title>Responsive Design Example</title> <style> .container { max-width: 960px; margin: 0 auto; padding: 20px; background-color: #f5f5f5; text-align: center; } h1 { font-size: 36px; margin-bottom: 20px; } p { font-size: 18px; line-height: 1.5; margin-bottom: 30px; } @media screen and (max-width: 768px) { h1 { font-size: 24px; margin-bottom: 10px; } p { font-size: 16px; margin-bottom: 20px; } } @media screen and (max-width: 480px) { h1 { font-size: 20px; margin-bottom: 10px; } p { font-size: 14px; margin-bottom: 10px; } } </style> </head> <body> <div class="container"> <h1>Responsive Design Example</h1> <p> This is an example of a responsive website design. Try resizing your browser window to see how the layout and font sizes change based on the screen size. </p> </div> </body> </html> Output:
