Web Accessibility
Web Accessibility is a principle that tries to make sure visitors with disabilities can locate, navigate, read and understand web content. The main impairments covered by this are:
• Vision, e.g. blindness, colour blindness. These are the most common among many people these days.
• Hearing, e.g. deafness. The thing generally a hurdle if website is encoded with some videos or audio equipments.
• Physical and speech, e.g. restricted use of limbs. Genrally not a disability in the path of website .
• Cognitive, e.g. learning difficulties. The worst ever difficulty which is very rare although but very bad.
There are many techniques which can help a disabled person to read the site and do work according to it. For instance, a well-made website can be easily used by a blind person using a program called a ‘Screen Reader’. It entirely depends on the coder as well as the resources how much he/she get to work upon it. This software vocalises content on a page and do work according to the user’s ability but it needs to be done very precisely and carefully. Unfortunately, carelessness or lack of foresight during development can render a website unusable to many. As such, many organisations follow the guidelines of the Web Accessibility Initiative (WAI). This organisation has created a set of standards called the Web Content Accessibility Guidelines (WGAC) – in 3 levels (A, AA & AAA) – that, when followed, make a website accessible. However, accessibility is not just about code. The way you write content can also influence whether you meet the WCAG standard or not. In general, you should aim for clarity and simplicity in writing. It also aims at the necessity and usefulness of a website to the user whether disabled or not. Moreover it also takes care that all the specific requirements are fulfilled by the developer as well as the user about the website development. It is in other words is similar to the TRAI for website development .
