Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:{class} to only apply the {class} utility on hover.

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:{class} to apply the {class} utility at only medium screen sizes and above.
