Web accessibility refers to the inclusive practice of designing and developing websites, tools, and technologies that can be used by everyone, not just people with disabilities. This encompasses individuals with visual, auditory, physical, speech, cognitive, language, learning, and neurological disabilities. The goal of web accessibility is to ensure that digital content is perceivable, operable, understandable, and robust for all users, regardless of their abilities or the tools they use to access the web.
With more of our lives taking place online, from education and employment to shopping and healthcare, the importance of digital accessibility cannot be overstated. Without it, individuals with disabilities are unable to interact with vital online services and opportunities.
Why is Web Accessibility Important?
Ensuring Equal Access for All
Web accessibility is essential for providing equal access and opportunity to all individuals. In the United States, the Lov om amerikanske borgere med nedsatt funksjonsevne (ADA) has been interpreted to include digital spaces, meaning websites must be accessible to avoid legal consequences. Similarly, the Retningslinjer for tilgjengelighet til webinnhold (WCAG) offer a widely adopted international standard for web accessibility.
Beyond legal compliance, embracing digital accessibility is a reflection of an organization’s commitment to social responsibility and inclusivity. By ensuring everyone can participate fully in digital life, companies and institutions help break down barriers and promote equity.
Impact on User Experience
Web accessibility improves the overall user experience for everyone. Accessible websites are often clearer, more organized, and easier to navigate. Features like captions, alternative text, and keyboard shortcuts benefit users with disabilities and also help people using mobile devices, older adults, and those with temporary impairments such as a broken arm or eye strain.
Key Principles of Web Accessibility
The WCAG framework is built around four foundational principles, often abbreviated as POUR:
Oppfattelig
Information and user interface components must be presentable to users in ways they can perceive. This includes providing alt text for images, using captions for videos, and ensuring content is distinguishable with proper color contrast and readable text.
Operable
All users must be able to interact with and use the interface. This involves enabling keyboard navigation, ensuring links and buttons are easily clickable, and preventing content that could trigger seizures or physical reactions.
Forståelig
Users should be able to understand both the content and its interface. Consistent navigation, clear instructions, and readable language help users interact effectively with digital content.
Robust
Content must be robust enough to be interpreted by a wide variety of user agents, including assistive technologies like screen readers. This means using clean, semantic HTML and testing across different devices and browsers to ensure broad compatibility.
Common Web Accessibility Features
Text Alternatives for Images
Alt text provides a text-based description of images so that users who rely on screen readers can understand the visual content. It’s essential for communicating the meaning of images, graphs, and other visual elements.
Tastaturnavigasjon
Accessible websites allow users to navigate using only a keyboard. This is crucial for users who cannot use a mouse due to motor disabilities. Common practices include logical tab order and visible focus indicators for interactive elements.
Tilgjengelige skjemaer
Forms should be clearly labeled and easy to navigate. Each form field must have an associated label, and error messages should be easy to understand. Form instructions should be available in multiple formats, where possible.
Color Contrast and Readability
Good contrast between text and the background ensures content is readable by users with low vision or color blindness. Using a minimum contrast ratio of 4.5:1 for normal text is recommended by WCAG.
Testing Web Accessibility
Automated Tools vs. Manual Testing
Automated tools can help identify common web accessibility issues quickly, but they only catch a portion of what needs to be addressed. By carrying out manual testing using screen readers such as NVDA or JAWS, you can experience your website as users with visual impairments would. This hands-on approach allows you to detect issues with reading order, link clarity, alternative text accuracy, form labels, and user interaction that automated tools often miss.
Manual testing also ensures that your web content meets the needs of users with a variety of disabilities, including cognitive and motor impairments. Navigating a site using only a keyboard or checking how clearly content is structured can reveal usability challenges that would otherwise go unnoticed. A combined approach, using both automated checks and manual reviews, provides a more thorough and inclusive accessibility evaluation.

Best Practices for Improving Web Accessibility
Follow WCAG Guidelines
The WCAG provides a clear roadmap for achieving web accessibility. Focus on meeting Level AA criteria as a standard benchmark, covering aspects like contrast, navigation, and multimedia alternatives.
Conduct Regular Audits
Accessibility is not a one-time task. Regular audits help ensure new content or updates do not introduce barriers. Automated tools and manual reviews should be part of ongoing maintenance.
Brukertesting med personer med nedsatt funksjonsevne
Real-world, human feedback is invaluable. Engaging users with disabilities in usability testing can uncover issues that automated tools miss, leading to more inclusive designs.
Legal Considerations and Web Accessibility Laws
ADA Compliance
Den ADA is a civil rights law in the United States that prohibits discrimination based on disability. While it originally applied to physical spaces, courts have increasingly interpreted it to include digital content, particularly for businesses and public services.
WCAG and Global Standards
Outside the U.S., many countries have adopted WCAG or similar standards. For example:
- The European Union requires public websites to follow EN 301 549, based on WCAG.
- Canada enforces accessibility through the Lov om et tilgjengelig Canada and provincial laws like AODA.
- Australia’s Disability Discrimination Act also emphasizes digital inclusion.
Making the Web More Inclusive for Everyone
Web accessibility ensures that all users can access, understand, and interact with digital content regardless of their abilities. Implementing accessibility is not just about avoiding legal risks – it’s about making digital spaces more welcoming, usable, and inclusive. By adopting tilgjengelighetsstandarder and continuously improving design practices, organizations can build a better functioning web for all.
Common Questions About Web Accessibility
What is the difference between accessibility and usability?
Accessibility refers to designing digital content and tools that people with disabilities can use. Usability focuses on the overall user experience for everyone. While related, accessibility ensures access while usability ensures effectiveness and satisfaction.
How do I make my website WCAG compliant?
Start by reviewing WCAG guidelines and conducting a web accessibility audit using both automated tools and manual testing. Address issues such as missing alt text, poor color contrast, and inaccessible forms. Regularly update content and involve users with disabilities in testing.
Can a website be fully accessible?
A website can strive to meet all WCAG criteria and be highly accessible, but “fully accessible” may vary depending on user needs and contexts. Continuous improvement, user feedback, and inclusive design are key to maintaining strong digital accessibility over time.
