Making your Website WCAG Compliant

WCAG stands for Web Content Accessibility Guidelines, these guidelines will make content more accessible to a wider range of people with disabilities. These are platform independent and address the accessibility of web content on desktops, laptops, tablets, and mobile devices.

Accessibility addresses all the issues including auditory, cognitive, neurological, physical, speech and visual. When it comes to mobile, more issues like small screen sizes, hijacked scrolling, cognitive load, ambiguous icons, conflicting gestures, different input modes, usability etc need to be addressed.

While designing for web, identifying the accessibility problems in the early stages of development using the right tools and techniques make it easier to address them. However, these tools are necessary but not sufficient and a knowledgeable human evaluation is required to determine if the site is accessible.

In this presentation, Aayush has highlighted the entry barriers to accessibility, helping you with tools and human evaluation required to analyze accessibility issues for your websites and the techniques to resolve those issues.
