In our previous blog post, “[Making Your Website Accessible to All: An Introduction to Web Accessibility](https://dev.to/awalakaushik/1-making-your-website-accessible-to-all-an-introduction-to-web-accessibility-2elc),” we discussed the importance of web accessibility and the basic principles to follow. This post will delve deeper into the topic and discuss the WCAG guidelines for web accessibility.

## WCAG Guidelines
The World Wide Web Consortium (W3C) created [Web Content Accessibility Guidelines](https://www.w3.org/WAI/standards-guidelines/wcag/) (WCAG) to provide a framework for making web content accessible to people with disabilities. WCAG has three levels of conformance: A, AA, and AAA, and each level builds upon the previous one and includes more stringent requirements. Four principles form the basis of the WCAG guidelines: **perceivable**, **operable**, **understandable**, and **robust**. We must present content so all users, including those with disabilities, can perceive it (**P**erceivable). Users must be able to navigate and interact with the content (**O**perable). Content must be explicit and easy to understand (**U**nderstandable). Finally, content must be compatible with different assistive technologies (**R**obust).

## Commonly Ignored Practices in Web Accessibility
Despite the importance of web accessibility, there are still practices that many commonly ignore. Some of these practices include:

1. Providing alternative text for images
2. Using proper heading structure
3. Ensuring that forms are accessible
4. Providing keyboard navigation
5. Ensuring that videos have captions and audio descriptions

Ignoring these practices can make it difficult or impossible for people with disabilities to access and interact with web content. It’s essential to prioritize these practices in web development to ensure that websites are accessible to everyone.

## Importance of Accessibility Testing
Accessibility testing evaluates a website or application to ensure it meets the WCAG guidelines. It’s essential to test for accessibility because it’s the only way to know if your website is genuinely accessible to all users, including those with disabilities. There are several types of accessibility testing, such as automated and manual testing. Many tools and resources are available such as [WAVE](https://wave.webaim.org/), [Axe](https://www.deque.com/axe/), [Tenon](https://tenon.io/), [Accessibility Insights](https://accessibilityinsights.io/), and so on, to help with testing.

## Conclusion
In conclusion, understanding the WCAG guidelines is crucial for creating accessible websites and digital content. By following these guidelines and prioritizing commonly ignored practices, we can ensure everyone, including people with disabilities, can access and interact with web content. It’s important to remember that accessibility is not a one-time effort but an ongoing process that requires regular testing and updates. Let’s work together to make the web a more inclusive and accessible place for all.
