Ulitimate Basic of Web Accessibility



Web accessibility refers to the practice of creating web content that is accessible to everyone, including people with disabilities. This is important because it ensures that all individuals, regardless of their abilities, can access and use web content. Accessibility standards and guidelines have been developed to help web developers create accessible web content. In this blog post, we will discuss the importance of web accessibility and provide an overview of accessibility standards and guidelines.

Types of Disabilities


When designing and developing websites, it’s important to consider how people with disabilities might interact with your content. Disabilities can range from visual impairments, such as color blindness and low vision, to auditory impairments, such as deafness and hearing loss. Motor impairments, such as paralysis or tremors, can also affect a person’s ability to use a mouse or keyboard effectively. Additionally, cognitive disabilities, such as dyslexia or attention-deficit/hyperactivity disorder (ADHD), can make it difficult to process information on a web page.

It’s important to keep in mind that each disability affects people in different ways, and what works for one person may not work for another. Therefore, it’s crucial to design and develop with a wide range of accessibility needs in mind.

Web Accessibility Guidelines


  • Briefly introduce the topic of web accessibility and why it matters
  • Explain that in order to create web content that is accessible to everyone, including people with disabilities, it’s important to follow accessibility guidelines
  • Provide an overview of the main accessibility guidelines, such as WCAG 2.1, and the different levels of conformance (A, AA, AAA)

II. Types of Disabilities

  • Discuss the different types of disabilities that can affect web accessibility, including visual, auditory, motor, and cognitive disabilities
  • Provide examples of how these disabilities can affect web browsing and interaction
  • Emphasize that by making web content accessible, we can improve the user experience for everyone, not just people with disabilities

III. Common Accessibility Issues and Fixes

  • Discuss some common accessibility issues that can arise in web content, such as lack of alt text on images, poor color contrast, and lack of keyboard navigation
  • Provide examples of how to fix these issues, such as adding alt text to images, increasing color contrast, and ensuring that all content can be accessed with a keyboard
  • Emphasize that these fixes not only improve accessibility, but also improve the overall usability and user experience of the web content

IV. Testing and Evaluating Accessibility

  • Explain the importance of testing and evaluating web content for accessibility
  • Provide examples of accessibility testing tools, such as screen readers and color contrast checkers
  • Discuss the importance of user testing and feedback, and how to incorporate it into the accessibility evaluation process

V. Conclusion

  • Recap the key points discussed in the blog post, including the importance of web accessibility, the main accessibility guidelines, common accessibility issues and fixes, and testing and evaluating accessibility
  • Provide some additional resources for further learning about web accessibility, such as the WCAG website and accessibility blogs and forums

Accessibility Testing

Accessibility Testing

Overview of automated and manual testing tools for web accessibility Explanation of how to test for accessibility issues using screen readers and other assistive technologies

Testing is an essential part of the web development process, especially when it comes to web accessibility. There are different types of testing techniques and tools available to ensure web content is accessible to everyone.

Automated Testing

Automated testing tools can help identify accessibility issues in web content. These tools scan web pages and provide a report of accessibility violations. Some popular automated testing tools include:

  • Axe: an open-source accessibility testing tool that integrates with different browsers and testing frameworks.
  • Lighthouse: a tool available in Google Chrome Developer Tools that provides a comprehensive report on web page performance, accessibility, and best practices.
  • Wave: a web accessibility evaluation tool that provides a list of accessibility issues found in a web page.

Manual Testing

Manual testing is a crucial part of accessibility testing. It involves testing web content with assistive technologies such as screen readers and keyboard-only navigation. Manual testing helps identify issues that automated tools cannot detect, such as issues with page structure, semantic markup, and keyboard accessibility.

Some assistive technologies to use for manual testing include:

  • Screen readers such as NVDA, JAWS, and VoiceOver: screen readers read out the content on a web page to people who are blind or visually impaired.
  • Keyboard-only navigation: testing the website without a mouse to ensure keyboard accessibility.

Accessibility testing can be done at different stages of the web development process, including during development and before deployment.


Web accessibility is essential to ensure that everyone, including people with disabilities, can access and use web content. Testing for accessibility issues is a critical step in the web development process. Automated testing tools and manual testing with assistive technologies can help ensure that web content is accessible to everyone.


Web accessibility is an essential aspect of creating a truly inclusive web. By following established accessibility guidelines and implementing best practices in design and development, we can create web content that is accessible to everyone, including those with disabilities. There are many tools and resources available to help us test and improve accessibility, and it’s important to make accessibility a priority from the beginning of any web project. By doing so, we can help ensure that everyone can access and interact with our web content, regardless of their abilities.

If you’re interested in learning more about web accessibility, there are many excellent resources available. The Web Content Accessibility Guidelines (WCAG) 2.1 are a great place to start, as they provide a comprehensive set of guidelines for creating accessible web content. Additionally, there are many organizations and communities dedicated to promoting web accessibility, such as the Accessibility Guidelines Working Group and the Web Accessibility Initiative. By continuing to learn and improve our accessibility practices, we can help create a web that is truly accessible to everyone.
