Why Contrast Matters
Accessibility isn't just a "nice-to-have" feature; it's a fundamental aspect of modern web design. High contrast between text and background ensures that your content is legible for people with low vision or color blindness. It also improves usability for everyone in different lighting conditions, like viewing a screen in bright sunlight.
