• It includes recommendations for making web content perceivable, operable, understandable, and robust.

Why Understanding WCAG is Crucial?

• Legal Requirements: Many countries have laws requiring conformance to WCAG for public websites.
• User Experience: Following WCAG guidelines makes web content more usable to users with and without disabilities.
• SEO Benefits: WCAG compliance can improve search engine rankings and increase the visibility of your website.

In this guide, we’ll delve into the details of WCAG, explaining its different versions, success criteria, and how to ensure your web content conforms to Level AA requirements.
