Best Practices for Ensuring Compliance
1. Introduction
This tutorial aims to provide a comprehensive guide on the best practices to ensure compliance with web accessibility laws and guidelines. By the end of this tutorial, you will be familiar with the key concepts of web accessibility and be more equipped to create websites that are inclusive and accessible to all users.
Prerequisites: Familiarity with HTML, CSS, and JavaScript will be beneficial but not necessary. Beginners are welcome!
2. Step-by-Step Guide
To understand web accessibility, you need to know the Web Content Accessibility Guidelines (WCAG). They are divided into four principles: Perceivable, Operable, Understandable, and Robust (POUR).
- Perceivable: The user must be able to perceive the information being presented.
- Operable: The user must be able to operate the interface.
- Understandable: The user must be able to understand the information and the interface.
- Robust: The user must be able to access the content as technologies advance.
Here are some best practices and tips to ensure your website is accessible:
- Use semantic HTML: Semantic HTML elements like
<header>,<nav>,<main>,<section>,<article>, and<footer>provide information about the structure of the content. - Provide text alternatives for non-text content: This includes images, audio, and video files. Use
altattribute in<img>tags. - Ensure sufficient color contrast: This helps people with moderate visual impairment to distinguish different parts of the content without the need for additional tools.
- Use ARIA (Accessible Rich Internet Applications) attributes: ARIA attributes provide additional information about elements to assistive technologies.
3. Code Examples
Example 1: Using semantic HTML
<!-- This is a simple example of a semantic HTML structure -->
<!DOCTYPE html>
<html>
<head>
<title>My Site</title>
</head>
<body>
<header>
<h1>My Site</h1>
<nav>
<ul>
<li><a href="#home">Home</a></li>
<li><a href="#about">About</a></li>
</ul>
</nav>
</header>
<main>
<section>
<h2>Welcome to My Site</h2>
<p>This is the home page.</p>
</section>
</main>
<footer>
<p>© 2021 My Site</p>
</footer>
</body>
</html>
Example 2: Providing text alternatives for images
<!-- This is a simple example of providing text alternatives for images -->
<img src="my-image.jpg" alt="Description of the image">
4. Summary
In this tutorial, we covered the four principles of WCAG (Perceivable, Operable, Understandable, and Robust) and the best practices for ensuring web accessibility compliance.
To continue learning about web accessibility, consider diving deeper into the WCAG guidelines and ARIA attributes. Web Accessibility Initiative (WAI) is a great resource for further learning.
5. Practice Exercises
Exercise 1: Write the semantic HTML for a simple blog post.
Exercise 2: Provide a text alternative for an image in HTML.
Exercise 3: Use ARIA roles in a navigation menu.

</ul>
</nav>
