Basic Usage

Changing enter animation starting opacity

Set the starting opacity of an animation using the fade-in-{amount} utilities.

<button class="animate-in fade-in ...">Button A</button>
<button class="animate-in fade-in-25 ...">Button B</button>
<button class="animate-in fade-in-50 ...">Button C</button>
<button class="animate-in fade-in-75 ...">Button C</button>

Applying Conditionally

Hover, focus, and other states

Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:fade-in-50 to only apply the fade-in-50 utility on hover.

<div class="animate-bounce fade-in-25 hover:fade-in-50">
	<!-- ... -->
</div>

For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.

Breakpoints and media queries

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:fade-in-50 to apply the fade-in-50 utility at only medium screen sizes and above.

<div class="animate-bounce fade-in-25 md:fade-in-50">
	<!-- ... -->
</div>

To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.

Using custom values

Customizing your theme

By default, Tailwind makes the entire default opacity scale available as animation opacities. You can customize your opacity scale by editing theme.opacity or theme.extend.opacity in your tailwind.config.js file.

// @filename tailwind.config.js
module.exports = {
	theme: {
		extend: {
			opacity: {
				67: ".67",
			},
		},
	},
}

Alternatively, you can customize just your animation opacities by editing theme.animationOpacity or theme.extend.animationOpacity in your tailwind.config.js file.

Learn more about customizing the default theme in the theme customization documentation.

Arbitrary values

If you need to use a one-off animation opacity value that doesn’t make sense to include in your theme, use square brackets to generate a property on the fly using any arbitrary value.

<div class="fade-in-[.67]">
	<!-- ... -->
</div>

Learn more about arbitrary value support in the arbitrary values documentation.
