Transition Timing Function

Tailwind CSS version

Utilities for controlling the easing of CSS transitions.

Class reference

.ease-lineartransition-timing-function: linear;
.ease-intransition-timing-function: cubic-bezier(0.4, 0, 1, 1);
.ease-outtransition-timing-function: cubic-bezier(0, 0, 0.2, 1);
.ease-in-outtransition-timing-function: cubic-bezier(0.4, 0, 0.2, 1);


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

<button class="transition ease-in duration-700 ...">Hover me</button>
<button class="transition ease-out duration-700 ...">Hover me</button>
<button class="transition ease-in-out duration-700 ...">Hover me</button>


To control an element's transition-timing-function at a specific breakpoint, add a {screen}: prefix to any existing transition-timing-function utility. For example, use md:ease-in-out to apply the ease-in-out utility at only medium screen sizes and above.

Timing values

By default Tailwind provides four general purpose transition-timing-function utilities. You change, add, or remove these by customizing the transitionTimingFunction section of your Tailwind theme config.

  // tailwind.config.js
  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.

Responsive and pseudo-class variants

By default, only responsive variants are generated for transition-timing-function utilities.

You can control which variants are generated for the transition-timing-function utilities by modifying the transitionTimingFunction property in the variants section of your tailwind.config.js file.

For example, this config will also generate hover and focus variants:

  // tailwind.config.js
  module.exports = {
    variants: {
      // ...
-     transitionTimingFunction: ['responsive'],
+     transitionTimingFunction: ['responsive', 'hover', 'focus'],


If you don't plan to use the transition-timing-function utilities in your project, you can disable them entirely by setting the transitionTimingFunction property to false in the corePlugins section of your config file:

  // tailwind.config.js
  module.exports = {
    corePlugins: {
      // ...
+     transitionTimingFunction: false,
