What are the Web Content Accessibility Guidelines (WCAG) 2.0?
The Web Content Accessibility Guidelines (WCAG) 2.0 is a set of international standards aimed at making websites accessible to all users. These guidelines provide guidelines for developing content that is easy to view, navigate, and understand by any visitor.
In this section, we'll look at what exactly WCAG 2.0 guidelines are, how it has evolved, and what its purpose is. We'll also discuss who the main users of these guidelines are and why it's important to follow WCAG 2.0 in building your website.
Definition and Purpose of WCAG 2.0
The Web Content Accessibility Guidelines (WCAG) 2.0 was created by the World Wide Web Consortium (W3C) to make web content accessible to everyone. They aim to ensure that every person, can use and understand the content of a website.
The WCAG 2.0 guidelines are based on four principles: Perceivable, Operable, Understandable, and Robust. For example, a website should have alternative text for images and be navigable with a keyboard.
The guidelines improve the user experience for everyone, including older people and people with temporary disabilities. According to statistics, around 15% of the world's population lives with some form of disability. Compliance with WCAG 2.0 helps ensure that this significant percentage of people have equal access to the web.
Background and Evolution of the Guidelines
The WCAG guidelines started in 1999 with WCAG 1.0 and were upgraded in 2008 to WCAG 2.0. 2.0 is based on the POUR principles, is more flexible, and has been widely adopted globally. In 2018, WCAG 2.1 guidelines were introduced, focusing on mobile devices and cognitive disabilities, while WCAG 2.0 remains the standard.
Who are the Main Users of WCAG 2.0?
The primary users of WCAG 2.0 standards are people with disabilities, including people with limited mobility, cognitive disabilities, or sensory difficulties. In addition, WCAG 2.0 guidelines also favor older people or people with distraction problems.
According to the World Health Organization (WHO), about 15% of the world's population lives with some form of disability. These WCAG 2.0 standards ensure that everyone has free access to the digital world.
The Four Principles of the WCAG 2.0 Web Content Accessibility Guidelines
The WCAG 2.0 guidelines are based on four fundamental principles, known by the acronym POUR: Perceivable, Operable, Understandable, and Robust. These principles ensure that websites and applications are accessible to all users, regardless of their needs and abilities.
Each principle covers different aspects of accessibility and offers guidelines for developing websites and applications that are accessible to all. This introduction will first examine these four principles and their relevance to web accessibility.
Perceivable (Perceivable)
Content must be presented in ways that users can perceive. This means that information must be available in more than one sense (e.g. visual and auditory).
- Use alternative text for images.
- Ensure that colors have sufficient contrast to be readable.
- Provide subtitles and captions for videos.
Operable:
- Interface elements should be operable in a variety of ways (e.g. via keyboard and voice commands).
- Make sure the colors are clearly visible for easy reading.
- Offer alternative ways of navigation such as searches and sitemaps.
Understandable
- Users should be able to understand the information as well as how the website works.
- Use simple and clear language.
- Make sure forms are easy to fill out and provide clear instructions.
- Provide clear and consistent feedback when users make mistakes.
Robust
- Content must be readable enough to be reliably interpreted by a wide variety of users, including those using assistive technologies.
- Use HTML semantic and ARIA landmarks to improve accessibility.
- Test your website with different browsers and devices to ensure compatibility.
Levels of Compliance with the WCAG 2.0 Web Content Accessibility Guidelines
The levels of compliance in the WCAG 2.0 guidelines define the degree to which a website is accessible. Each level (A, AA, AAA) defines the requirements that a web page must meet to be considered accessible, with AAA being the highest level. Understanding these levels is important for developing websites that serve all users.
Level A
Level A of WCAG 2.0 guidelines includes the most basic accessibility requirements that a website must meet. Information such as alternative text for images, clear structure on the page using appropriate labels, and keyboard navigation are essential to achieve this level of compliance. Achieving Level A is an important first step in ensuring that your website is accessible to all users, including people with disabilities and other special needs.
Level AA
Level AA of the WCAG 2.0 guidelines requires additions to accessibility beyond Level A. It includes more advanced requirements focused on ensuring that the website is accessible to all users. Compliance with Level AA enhances the accessibility of your website, providing a higher-quality user experience.
AAA level
The AAA level refers to the most advanced accessibility requirements of the WCAG 2.0 guidelines. These requirements focus on ensuring accessibility for all categories of users, including those with severe disabilities. Compliance with the AAA level enhances the accessibility of your website, providing an extended experience that caters to all users.
How to Choose the Appropriate Compliance Level for your Website
Choosing the appropriate level of compliance with the WCAG 2.0 guidelines depends on many factors, including the goal of your website, your resources, and your community. Carefully evaluate your needs and capabilities before making a decision. Work with experts and consider your community's priorities.
Best Practices for Compliance with the WCAG 2.0 Web Content Accessibility Guidelines
Understanding and implementing best practices to comply with the WCAG 2.0 guidelines is fundamental to creating accessible and usable websites. In this section, we will review some of the key practices for achieving compliance. By following these approaches, you can ensure that your website is accessible and user-friendly, promoting true digital inclusion and accessibility.
Design with Accessibility
Proper accessibility website design is critical to creating an accessible environment for all. Ensuring accessibility can be achieved by choosing the right color schemes and using appropriate markup on forms and keyboard navigation. This ensures the construction of an accessible website that is easy to use for all.
Audit and Compliance Testing
During the audit and compliance testing phase, you review your website for compliance with WCAG 2.0 standards. This includes evaluating the structure, navigation, content, and functionality of the website to ensure accessibility for all users. You then implement corrections for any compliance deficiencies, ensuring all users can access the site.

Using accessibility tools is important to assess the accessibility level of your website. By using these tools, you can identify potential accessibility problems and take appropriate steps to improve them. These tools usually offer reports with suggestions for improvements, helping you to achieve maximum accessibility for all users.
Common Problems with the WCAG 2.0 Web Content Accessibility Guidelines and How to Address Them
Web accessibility is an issue that many website owners face. Some of the common problems include a lack of readiness for users with disabilities, inadequate use of tags, and complicated navigation. However, there are effective ways to address these problems and improve the accessibility of your website. In this section, we will look at the most common accessibility problems and present practical solutions to address them.
Incomplete Alternative Text for Images
The alternative text for images provides important information for visually impaired users using screen readers. It should be short and concise, providing the necessary information about the content of the image. Good practices include the use of concise descriptions and references to the purpose of the image.
Inadequate Color Contrast
The insufficient color contrast makes it difficult for people with references and limited vision to read and understand the content. Choosing appropriate color combinations with sufficient contrast helps to easily identify content.
Unfriendly Keyboard Navigation
Unfriendly keyboard navigation is a barrier for people with limited mobility who depend on using a keyboard to navigate the website. By providing appropriately designed and programmed keyboard navigation features, we help users interact easily with the website, regardless of their difficulties.
