Legal Requirements for Web Accessibility
The Americans with Disabilities Act (ADA)
The ADA is a landmark U.S. civil rights law that prohibits discrimination against individuals with disabilities. Under Title III of the ADA, businesses and organizations operating in places of public accommodation, including websites, are required to provide equal access to individuals with disabilities. This includes making websites accessible and ensuring that they do not discriminate against individuals with disabilities.
Section 508 of the Rehabilitation Act
Section 508 of the Rehabilitation Act requires federal agencies to make their electronic and information technology accessible to people with disabilities. This includes websites and other digital resources created or used by the federal government. Compliance with Section 508 ensures that individuals with disabilities can access and use government services and information on an equal basis with others.
Web Content Accessibility Guidelines (WCAG)
The Web Content Accessibility Guidelines (WCAG) are internationally recognized standards for web accessibility. They provide a comprehensive set of guidelines and success criteria that website owners and developers can follow to make their websites accessible. Developed by the Web Accessibility Initiative (WAI), the WCAG is widely used as a reference for creating inclusive and accessible web content.
Common Barriers to Web Accessibility
Visual impairments
Visual impairments can range from partial sight to complete blindness. Websites should be designed to accommodate users with visual impairments by providing alternative text descriptions for images, ensuring sufficient color contrast, and allowing users to navigate and interact with the site using assistive technologies like screen readers.

This means that all interactive elements, such as buttons and links, should be accessible through keyboard commands.
Cognitive impairments
Cognitive impairments may affect memory, concentration, or comprehension, making it challenging for some individuals to navigate complex websites. To make websites more accessible to users with cognitive impairments, it is important to use simple and consistent navigation structures, clear language, and minimize distractions and unnecessary animations.
Designing for Web Accessibility
Text alternatives for non-text content
Providing alternative text descriptions, also known as alt text, for non-text content such as images and infographics is crucial for individuals who rely on screen readers or have visual impairments. Alt text should be descriptive and convey the meaning and purpose of the visual content.
Sufficient color contrast
Using colors with sufficient contrast is important for individuals with visual impairments or color blindness. Ensuring that text and other visual elements stand out clearly from the background improves readability and accessibility.
Clear and consistent navigation
Clear and consistent navigation is essential for all users, including those with disabilities. Websites should have a logical and intuitive structure, with clearly labeled links and menus. Sitemaps and breadcrumbs can also help users navigate efficiently.
Keyboard accessibility
Keyboard accessibility ensures that users can navigate and interact with a website using only a keyboard or other input devices. This is particularly important for individuals with motor impairments who may find it difficult to use a mouse. All interactive elements should be accessible and operable via keyboard commands.
Making Multimedia Accessible
Transcriptions for audio content
Adding transcriptions for audio content, such as podcasts or audio clips, allows individuals with hearing impairments to access the information. Transcriptions should accurately represent the audio content and include any spoken words and relevant sounds.
Captioning for video content
Captioning involves displaying the text version of the audio component of videos, allowing individuals with hearing impairments to follow along. Captioning also benefits non-native speakers or users in noisy environments who may need visual confirmation of the spoken words.
Audio descriptions for visually impaired users
Audio descriptions provide additional narration to describe visual elements of videos or multimedia content. By incorporating audio descriptions, individuals with visual impairments can understand and enjoy visual content that would otherwise be inaccessible to them.
Accessible Forms and Documents
Using form labels and placeholders
Labels and placeholders should be used in forms to provide clear instructions and identify input fields. This helps individuals with cognitive impairments or visual impairments understand the purpose of each form field and ensures accurate completion.
Providing error messages and suggestions
Error messages and suggestions should be displayed when users encounter issues filling out a form. Clear error messages help individuals with cognitive impairments identify and correct errors, improving the overall user experience.
Using accessible document formats
When providing downloadable documents on a website, it is important to use accessible formats such as PDFs that include text recognition. Accessible document formats ensure that individuals using assistive technologies can access and interact with the content effectively.
Ensuring Compatibility with Assistive Technologies
Screen readers
Screen readers are assistive technologies that read aloud the content displayed on a computer screen. Websites should be designed and developed in a way that is compatible with screen readers, ensuring that individuals with visual impairments can access the information effectively.
Screen magnifiers
Screen magnifiers are assistive technologies that enlarge the content displayed on a computer screen. Web designers should ensure that their websites can be effectively magnified without loss of functionality or readability.
Braille displays
Braille displays convert on-screen text into Braille, allowing individuals with visual impairments to read and navigate websites through touch. Websites should be designed with compatibility for Braille displays, ensuring that the content can be accurately translated into Braille.
Speech recognition software
Speech recognition software allows individuals with motor impairments or those who have difficulty typing to navigate websites and input text using voice commands. Ensuring compatibility with speech recognition software can enhance accessibility for users who rely on this technology.
