Examples

Basic example

Use utilities like ease-in and ease-out to control the easing curve of an element's transition:

<button class="duration-300 ease-in ...">Button A</button>
<button class="duration-300 ease-out ...">Button B</button>
<button class="duration-300 ease-in-out ...">Button C</button>

Using a custom value

Use the ease-[<value>] syntax to set the transition timing function based on a completely custom value:

<button class="ease-[cubic-bezier(0.95,0.05,0.795,0.035)] ...">
  <!-- ... -->
</button>

For CSS variables, you can also use the ease-(<custom-property>) syntax:

<button class="ease-(--my-easing) ...">
  <!-- ... -->
</button>

This is just a shorthand for ease-[var(<custom-property>)] that adds the var() function for you automatically.

Responsive design

Prefix a transition-timing-function utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:

<button class="ease-out md:ease-in ...">
  <!-- ... -->
</button>

Learn more about using variants in the variants documentation.

Customizing your theme

The ease-* utilities are driven by the --ease-* theme variables, which can be customized in your own theme:

@theme {
  --ease-in: cubic-bezier(0.4, 0, 1, 1);
  --ease-out: cubic-bezier(0, 0, 0.2, 1);
  --ease-in-out: cubic-bezier(0.4, 0, 0.2, 1);
}

Learn more about customizing the easing scale in the theme variable documentation.
