Web Accessibility Guidelines - What and Why it matters

Web Content Accessibility Guidelines was conceived by World Wide Web Consortium (W3C) with a motive to make web and digital technology accessible for all. The first version of accessibility guidelines,WCAG 1.0 was released in May 5th 1999. It continued for about 10 years and in 2008, WCAG 2.0 was released. In addition to web properties, 2.0 also takes care of other digital assets like PDF, Documents, Google Docs, Spreadsheets, mobile app etc. Past 10 years has witnessed many technology changes, to cope-up with the technology changes and to bridge the known gaps in WCAG 2.0 , WCAG 2.1 was released in June 2018.
