Building Responsive UIs with Tailwind CSS

Tailwind CSS replaces context-switching between markup and stylesheets with utility classes you compose directly in your JSX.

Responsive by default

Breakpoint prefixes scale a layout from mobile to desktop with no media queries:

<div className="grid grid-cols-1 gap-4 md:grid-cols-2 lg:grid-cols-3">
  {items.map((item) => (
    <Card key={item.id} {...item} />
  ))}
</div>

Dark mode without the ceremony

Prefix any utility with dark: and it activates under the dark theme:

<article className="bg-gray-100 text-gray-900 dark:bg-slate-800 dark:text-gray-100">
  ...
</article>

Takeaway

Compose small utilities, extract a component when a pattern repeats, and lean on the design tokens in tailwind.config.js to stay consistent.
