Web Accessibility

1. Introduction

Web accessibility refers to the design and development of websites that can be accessed and used by all people, including those with disabilities. It encompasses various strategies and techniques to ensure that web content is perceivable, operable, understandable, and robust.

2. Importance of Accessibility

Ensuring accessibility is crucial for several reasons:

• Increases your audience reach.
• Enhances user experience for everyone.
• Improves SEO performance.
• Is a legal requirement in many jurisdictions.

3. Principles of Accessibility

The Web Content Accessibility Guidelines (WCAG) outlines four principles of accessibility, often referred to as POUR:

1. Perceivable: Information and user interface components must be presentable to users in ways they can perceive.
2. Operable: User interface components and navigation must be operable.
3. Understandable: Information and the operation of user interface must be understandable.
4. Robust: Content must be robust enough to be interpreted reliably by a wide variety of user agents, including assistive technologies.

4. Best Practices

Here are some best practices for web accessibility:

• Use semantic HTML to provide meaning and structure.
• Provide text alternatives for non-text content.
• Ensure sufficient color contrast between text and background.
• Use ARIA roles and properties to enhance accessibility.
• Design for keyboard navigation.
• Provide clear and consistent navigation options.

5. Code Examples

Below are some examples illustrating accessible web practices:

<img src="logo.png" alt="Company Logo" />
