Animation Fill Mode

Utilities for controlling the fill mode of CSS animations.

Class Properties
fill-mode-none animation-fill-mode: none;
fill-mode-forwards animation-fill-mode: forwards;
fill-mode-backwards animation-fill-mode: backwards;
fill-mode-both animation-fill-mode: both;

Basic Usage

Changing animation fill mode

Use the fill-mode-{keyword} utilities to control an element’s animation-fill-mode.

<button class="animate-bounce fill-mode-none ...">Button A</button>
<button class="animate-bounce fill-mode-forwards ...">Button B</button>
<button class="animate-bounce fill-mode-backwards ...">Button C</button>
<button class="animate-bounce fill-mode-both ...">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:fill-mode-forwards to only apply the fill-mode-forwards utility on hover.

<div
	class="animate-bounce duration-300 fill-mode-backwards hover:fill-mode-forwards"
>
	<!-- ... -->
</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:fill-mode-forwards to apply the fill-mode-forwards utility at only medium screen sizes and above.

<div
	class="animate-bounce duration-300 fill-mode-backwards md:fill-mode-forwards"
>
	<!-- ... -->
</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 provides animation-direction utilities for all of the built-in browser keyword options. You can customize these values by editing theme.animationDirection or theme.extend.animationDirection in your tailwind.config.js file.

// @filename tailwind.config.js
module.exports = {
	theme: {
		extend: {
			animationDirection: {
				"forwards-backwards": "forwards, backwards",
			},
		},
	},
}

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

Arbitrary values

If you need to use a one-off animation-fill-mode 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="fill-mode-[forwards,backwards]">
	<!-- ... -->
</div>

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