What is a CSS Easing Generator?

A CSS Easing Generator is an online tool that helps you create timing functions for CSS transitions and animations. Instead of guessing easing values manually, you can choose an easing preset, customize the curve, preview the motion and copy the generated CSS code.

Easing controls how an animation moves over time. It decides whether motion starts slowly, speeds up, slows down, feels snappy, feels soft or creates a more playful overshoot effect.

This CSS Easing Generator runs directly in your browser, making it fast and simple to create animation easing CSS without installing software.

What can you use it for?

You can use this online easing generator to create smoother buttons, hover effects, menu transitions, modal animations, card effects, sliders, dropdowns, page transitions, loading effects and micro-interactions.

For example, you may want a soft ease-out curve for a modal entrance, a snappy easing curve for a button hover, a balanced ease-in-out curve for a toggle, or a custom cubic-bezier curve for a branded animation style.

How to use the CSS Easing Generator

Step 1: Choose an easing style

Select an easing style such as linear, ease, ease-in, ease-out, ease-in-out or a custom cubic-bezier curve.

Step 2: Preview the motion

Use the live preview to see how the easing affects the animation. Adjust the curve, duration or timing values until the motion feels right.

Step 3: Copy the CSS code

Copy the generated easing CSS and use it in transition, transition-timing-function, animation or animation-timing-function.

What is easing in CSS?

Easing is the timing behavior of an animation or transition. It controls how quickly an element moves between its starting state and ending state.

Without easing, an animation may move at the same speed from beginning to end. This is called linear motion. Linear motion can be useful for loaders or continuous movement, but it often feels unnatural for interface interactions.

With easing, the motion can accelerate, decelerate or settle smoothly. This makes buttons, menus, cards, modals and page elements feel more polished and natural.

Basic CSS easing example

A simple easing function can be added to a CSS transition.

.button {
  transition: transform 0.25s ease-out;
}

.button:hover {
  transform: translateY(-4px);
}

In this example, ease-out controls how the button moves when the hover effect starts.

You can also use a custom cubic-bezier easing function.

.button {
  transition: transform 0.25s cubic-bezier(0.22, 1, 0.36, 1);
}

.button:hover {
  transform: translateY(-4px);
}

CSS transition easing

CSS transitions use easing to control the movement between two states, such as normal and hover.

.card {
  transition-property: transform, box-shadow;
  transition-duration: 0.3s;
  transition-timing-function: ease-out;
}

.card:hover {
  transform: translateY(-6px);
  box-shadow: 0 18px 40px rgba(0, 0, 0, 0.18);
}

Transition easing is useful for buttons, cards, links, images, menus, icons, form fields and other interactive elements.

CSS animation easing

CSS animations can also use easing to control how keyframes progress over time.

.modal {
  animation: modalIn 0.45s ease-out forwards;
}

@keyframes modalIn {
  from {
    opacity: 0;
    transform: translateY(24px) scale(0.96);
  }

  to {
    opacity: 1;
    transform: translateY(0) scale(1);
  }
}

Animation easing is useful for entrance effects, loaders, modals, notifications, banners, hero sections and decorative UI motion.

Common CSS easing values

Linear

Linear easing moves at the same speed from start to finish.

transition-timing-function: linear;

Linear motion is useful for continuous animations such as loaders, rotating icons or progress effects.

Ease

The ease value starts slowly, speeds up and then slows down near the end.

transition-timing-function: ease;

This is a common default easing value for general UI transitions.

Ease-in

The ease-in value starts slowly and speeds up toward the end.

transition-timing-function: ease-in;

Ease-in is often useful when an element is leaving the screen or moving away.

Ease-out

The ease-out value starts quickly and slows down near the end.

transition-timing-function: ease-out;

Ease-out is often useful when an element enters the screen or settles into place.

Ease-in-out

The ease-in-out value starts slowly, speeds up in the middle and slows down at the end.

transition-timing-function: ease-in-out;

Ease-in-out is useful for balanced motion, toggles, sliders and state changes.

Cubic-bezier

The cubic-bezier() function lets you create a custom easing curve.

transition-timing-function: cubic-bezier(0.16, 1, 0.3, 1);

Custom cubic-bezier easing is useful when you want more precise control over motion.

Custom cubic-bezier easing

A cubic-bezier easing function uses four values:

cubic-bezier(x1, y1, x2, y2)

These values define the shape of the timing curve. The curve controls how the animation progresses over time.

For example:

transition-timing-function: cubic-bezier(0.22, 1, 0.36, 1);

This type of easing can feel smooth and responsive for modern UI interactions.

Easing presets for UI motion

Smooth easing

Smooth easing is useful for cards, menus and modal entrances.

transition-timing-function: cubic-bezier(0.22, 1, 0.36, 1);

Snappy easing

Snappy easing is useful for fast UI feedback, button hovers and small interactions.

transition-timing-function: cubic-bezier(0.16, 1, 0.3, 1);

Soft easing

Soft easing is useful for calm interfaces, subtle hover effects and gentle transitions.

transition-timing-function: cubic-bezier(0.4, 0, 0.2, 1);

Overshoot easing

Overshoot easing can create a playful bounce-like effect.

transition-timing-function: cubic-bezier(0.34, 1.56, 0.64, 1);

Use overshoot carefully so the animation does not feel distracting.

Easing for hover effects

Hover effects usually feel better with a short duration and a smooth easing function.

.button {
  transition: transform 0.2s ease-out, box-shadow 0.2s ease-out;
}

.button:hover {
  transform: translateY(-3px);
  box-shadow: 0 14px 32px rgba(0, 0, 0, 0.2);
}

For more custom motion, use a cubic-bezier value:

.button {
  transition: transform 0.2s cubic-bezier(0.16, 1, 0.3, 1);
}

Easing for modals and menus

Modals and menus often feel better with ease-out motion because they enter quickly and settle smoothly.

.menu {
  transition: opacity 0.25s ease-out, transform 0.25s ease-out;
}

.menu.is-open {
  opacity: 1;
  transform: translateY(0);
}

For a more polished entrance, use a custom easing curve:

.menu {
  transition: opacity 0.3s cubic-bezier(0.16, 1, 0.3, 1),
              transform 0.3s cubic-bezier(0.16, 1, 0.3, 1);
}

Easing for CSS animations

Easing can be used directly in the animation shorthand property.

.badge {
  animation: popIn 0.45s cubic-bezier(0.34, 1.56, 0.64, 1) forwards;
}

@keyframes popIn {
  from {
    opacity: 0;
    transform: scale(0.8);
  }

  to {
    opacity: 1;
    transform: scale(1);
  }
}

This can create a lively pop-in effect for badges, notifications, icons and small UI elements.

Easing vs duration

Easing controls the rhythm of motion. Duration controls how long the motion takes.

A good easing curve can feel wrong if the duration is too slow or too fast. Small UI interactions often work well with short durations, while larger transitions usually need slightly more time.

For example:

transition: transform 0.2s ease-out;

This may work well for a button hover.

transition: opacity 0.45s ease-out, transform 0.45s ease-out;

This may work better for a modal or page section entrance.

Easing vs animation vs transition

Easing

Easing controls the timing curve of motion.

Transition

A transition animates a change between two states, such as normal and hover.

Animation

An animation uses keyframes and can run automatically, repeat or move through multiple stages.

Easing can be used with both transitions and animations.

Easing design tips

Use ease-out for entering elements

Elements that appear on screen often feel better when they start quickly and slow down into place.

Use ease-in for exiting elements

Elements leaving the screen often feel more natural when they start slowly and speed away.

Use ease-in-out for balanced state changes

Toggles, sliders and layout changes often feel smooth with ease-in-out motion.

Use linear for continuous motion

Spinners, loaders and infinite rotation often work better with linear timing.

Keep motion subtle

A small amount of easing can make UI feel polished. Extreme curves should be used only when they match the design.

Pair easing with transform and opacity

Animating transform and opacity usually feels smoother than animating layout-heavy properties.

Respect reduced motion

For accessibility, consider supporting users who prefer reduced motion.

@media (prefers-reduced-motion: reduce) {
  * {
    animation: none !important;
    transition: none !important;
  }
}

Common easing use cases

For buttons

Create smooth hover effects, press effects, CTA interactions and button lift animations.

For cards

Apply custom easing to card hover effects, shadow changes, image zoom effects and entrance animations.

For menus

Create dropdown menus, mobile navigation, sidebars and off-canvas panels with smoother motion.

For modals

Use easing for modal fade, slide, scale and pop-in effects.

For sliders

Create smoother carousel transitions, content sliders and UI panel changes.

For page transitions

Use easing to make sections, hero elements and layout changes feel more natural.
