Web Accessibility

Web accessibility ensures the internet is accessible to everyone, including those with disabilities. By designing websites and applications to be usable for people with a variety of disabilities—visual, auditory, physical, speech, cognitive, and neurological—we affirm that the web is a resource meant for all.

Why is Web Accessibility Important?

  • Inclusivity: The web is essential for accessing information, education, employment, government services, and social connections. Accessibility guarantees everyone equal access to these opportunities.
  • Legal Compliance: Digital accessibility is not only a good practice but also a legal requirement in many jurisdictions.
  • Broader Reach: Accessible websites can attract a wider audience, including the elderly and people with disabilities, increasing your potential user base.
  • Better SEO: Accessible sites tend to be more search engine friendly, which can enhance site visibility and ranking.

Key Principles of Web Accessibility

The Web Content Accessibility Guidelines (WCAG) outline how to make web content more accessible. The core principles are:

  1. Perceivable: Users must be able to perceive the information being presented, meaning that alternatives for non-text content should be provided, and it should be easier for users to see and hear content.
  2. Operable: All users should be able to operate the interface. This means ensuring keyboard accessibility and providing sufficient time for users to interact with content.
  3. Understandable: Information and the operation of the user interface must be understandable, making text readable and predictable and helping users avoid and correct mistakes.
  4. Robust: Content must be robust enough to be interpreted by a wide variety of user agents, including assistive technologies, ensuring compatibility with both current and future user tools.

Implementing Web Accessibility

Here are some actionable tips for making your website accessible:

  • Use semantic HTML: This improves how screen readers and other assistive technologies interpret and navigate your content.
  • Ensure sufficient contrast: There should be enough contrast between text and its background to be easily readable by users with low vision.
  • Make all functionality keyboard accessible: All site interactions should be possible using a keyboard, accommodating users who cannot use a mouse.
  • Provide alternatives for multimedia: Offer text transcripts for audio and captions or descriptions for videos.
  • Test your site with accessibility tools: Use various tools and checklists to assess and enhance your site’s accessibility.


Web accessibility is more than a technical standard; it’s a commitment to ensuring the internet is open and accessible to all. By adhering to the principles and implementation tips provided, websites can become more inclusive, reach a broader audience, and offer a better user experience for everyone.
