Improving website accessibility is crucial for ensuring all users, including those with disabilities, can access and navigate your site. To achieve this, consider using tools like WAVE, which evaluates your site for accessibility issues and provides suggestions for improvement. Another important tool is a color contrast checker, which helps ensure text and background colors have sufficient contrast for readability. Additionally, test your site with a screen reader to understand how visually impaired users experience it and ensure all functions can be accessed using only a keyboard. Finally, use semantic HTML elements like headings and landmarks to improve accessibility for assistive technologies. By incorporating these tools and techniques, you can make your website more inclusive and user-friendly for all visitors.
