Styling

All components use CSS variables from @manacore/shared-tailwind/themes.css and are fully theme-aware. They automatically adapt to the current theme variant and mode.

Custom Styling

You can override styles using the class prop or by targeting the component classes:

/* Custom toggle button */
.theme-toggle {
	background-color: var(--my-custom-bg);
}

/* Custom selector buttons */
.variant-button.active {
	box-shadow: 0 0 0 2px var(--my-custom-ring);
}
