Boost accessibility for high-contrast users with CSS

Web Content Accessibility Guidelines (WCAG) aim to enhance web accessibility for individuals with disabilities, particularly those with visual impairments, yet they often overlook the varying needs of users with low vision. While high-contrast mode is a critical tool used by approximately 30% of low-vision internet users to improve text legibility and reduce visual clutter, it remains underutilized by developers compared to other features like dark mode or screen reader compatibility. This is partly due to the misconception that implementing high-contrast mode requires extensive website modifications, which is not always the case. Developers can improve accessibility for high-contrast users by employing practices such as using semantic HTML, leveraging transparent values, and utilizing CSS properties like forced-colors and forced-adjust-colors. These strategies help ensure that websites remain functional and visually coherent for users who rely on high-contrast settings, particularly in Windows high-contrast mode, which adjusts on-screen elements for better visibility. Additionally, browser tools like Chrome DevTools can assist in diagnosing and addressing accessibility issues. Therefore, prioritizing high-contrast mode can significantly contribute to a more inclusive web environment.
