Introduction to Web Accessibility

When websites and web tools are properly designed and coded, people with disabilities can use them. However, currently, many sites and tools are developed with accessibility barriers that make them difficult or impossible for some people to use.


Making the web accessible benefits individuals, businesses, and society. International web standards define what is needed for accessibility. Accessibility in Context


Accessibility in Context

The power of the Web is in its universality.

Access by everyone regardless of disability is an essential aspect.


The Web is fundamentally designed to work for all people, whatever their hardware, software, language, location, or ability. When the Web meets this goal, it is accessible to people with a diverse range of hearing, movement, sight, and cognitive ability.


Thus the impact of disability is radically changed on the Web because the Web removes barriers to communication and interaction that many people face in the physical world. However, when websites, applications, technologies, or tools are badly designed, they can create barriers that exclude people from using the Web.


Accessibility is essential for developers and organizations that want to create high-quality websites and web tools, and not exclude people from using their products and services.


What is Web Accessibility


Web accessibility means that websites, tools, and technologies are designed and developed so that people with disabilities can use them?

More specifically, people can:

1. Perceive, understand, navigate, and interact with the Web

2. Contribute to the Web

Web accessibility encompasses all disabilities that affect access to the Web, including:


1. auditory

2. cognitive

3.neurological

4. physical

5.speech

6. visual


Web accessibility also benefits people without disabilities, for example:


1. people using mobile phones, smartwatches, smart TVs, and other devices with small screens, different input modes, etc.

2. older people with changing abilities due to aging

3. people with “temporary disabilities” such as a broken arm or lost glasses

4. people with “situational limitations” such as in bright sunlight or in an environment where they cannot listen to audio

5. people using a slow Internet connection, or who have limited or expensive bandwidth
