Transition Timing Function

​

Basic usage

​

Controlling the easing curve

Use the ease-{timing} utilities to control an element’s easing curve.

<button class="ease-in duration-300 ...">Button A</button>
<button class="ease-out duration-300 ...">Button B</button>
<button class="ease-in-out duration-300 ...">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:ease-in to only apply the ease-in utility on hover.

<div class="transition duration-150 ease-out hover:ease-in">
  <!-- ... -->
</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:ease-in to apply the ease-in utility at only medium screen sizes and above.

<div class="transition duration-150 ease-out md:ease-in">
  <!-- ... -->
</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 four general purpose transition-timing-function utilities. You can customize these values by editing theme.transitionTimingFunction or theme.extend.transitionTimingFunction in your tailwind.config.js file.

module.exports = {
  theme: {
    extend: {
      transitionTimingFunction: {
        'in-expo': 'cubic-bezier(0.95, 0.05, 0.795, 0.035)',
        'out-expo': 'cubic-bezier(0.19, 1, 0.22, 1)',
      }
    }
  }
}

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

​

Arbitrary values

If you need to use a one-off transition-timing-function 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="ease-[cubic-bezier(0.95,0.05,0.795,0.035)]">
  <!-- ... -->
</div>
