Problem: Error and success styling.

Solution#

html
<input class="w-full rounded-lg border border-red-400 ring-2 ring-red-100 px-3 py-2" />
<p class="mt-1 text-xs text-red-600">Email is required.</p>

Why this works#

Colored border + ring tint + helper text per state.

Variants#

  • Responsive: add screen prefixes to the core classes
  • Dark: pair each color utility with its dark: twin
  • Animated: add transition + a state variant for motion
