Introduction to Web Accessibility

What is Web Accessibility?

Web accessibility is all about making sure that websites and online content are easy to use for everyone, including people with disabilities. In today's world, where the internet is a big part of our lives, it's important to create websites and web applications that everyone can access, no matter what challenges they might have.

Why Web Accessibility is Important:

  1. For Everyone: Web accessibility is about including everyone, no matter if they have different disabilities. It's about making the internet a place where everyone feels welcome.

  2. Following the Rules: In some places, there are rules that say websites must be accessible to everyone. For example, in Poland, there are laws that emphasise the importance of making websites accessible for people with disabilities. This is particularly crucial for government websites, as Polish government websites should meet the accessibility requirements defined by the Web Content Accessibility Guidelines (WCAG) at level AA.

  3. Good for Business: Websites that are easy to use can attract more people and make customers happier. Also, being accessible shows that a company cares about being fair and inclusive.

Types of Disabilities:

  1. Visual: Some people have difficulty seeing or are completely unable to see. They may rely on screen readers or other assistive technologies to navigate the web.

  2. Hearing: Others may have difficulty hearing or be fully deaf. Providing captions for multimedia content ensures that they can comprehend information conveyed through audio.

  3. Motor: Certain individuals may struggle with using a mouse or keyboard due to motor impairments. Designing websites that are navigable using only a keyboard is essential for this group.

  4. Cognitive: Some people may have difficulty processing information or memory issues. Maintaining simple and straightforward content helps in these cases.

  5. Temporary disability - breakdowns or lost equipment, temporary injuries

Key Ideas for Web Accessibility:

  1. Easy to Understand: Information on websites should be easy to understand. This means providing text descriptions for images and clear navigation.

  2. Easy to Use: Websites should be easy to use, even if someone can't use a mouse. This includes using a keyboard and making sure users have enough time to read and do things.

  3. Clear and Simple: - Websites should be clear and simple. People should be able to understand what's going on and fix any mistakes they make.

  4. Works for Everyone: Websites should work with different technologies, so everyone can use them with different devices.

How to Make a Website Accessible:

  1. Use Semantic HTML: Use good HTML to organise content. This helps people who use special tools to understand the website better.

  2. Describe Images: Describe images so people who can't see them can still know what's in them.

  3. Easy Navigation: Make sure people can use the website just with a keyboard. This helps those who can't use a mouse.

  4. Colors and Contrast: Use colors carefully and make sure there's enough difference between text and background colors. This helps people with vision problems.

  5. Test and Get Feedback: Regularly check the website for accessibility. Ask people with disabilities to try it out and tell you what works and what doesn't.


In short, web accessibility is about making the internet a friendly place for everyone. Following these easy steps helps make sure that the internet is a tool that everyone can use, no matter what challenges they might face.
