CSS Animation-Duration Enhance Your Web Designs

What is animation-duration?

The animation-duration property in CSS controls how long an animation takes to complete one cycle. It’s essential for creating smooth and engaging animations that enhance user experience.

Syntax

Here’s how you can use animation-duration:

/* Single animation */
animation-duration: auto; /* Default */
animation-duration: 6s;
animation-duration: 120ms;

/* Multiple animations */
animation-duration: 1.64s, 15.22s;
animation-duration: 10s, 35s, 230ms;

/* Global values */
animation-duration: inherit;
animation-duration: initial;
animation-duration: revert;
animation-duration: revert-layer;
animation-duration: unset;

• auto: Equivalent to 0s for time-based animations. For scroll-driven animations, it fills the entire timeline.
• <time>: Specifies the duration in seconds (s) or milliseconds (ms). The value must be positive or zero.

Note: Negative values are invalid and will be ignored.

Property Values

• auto: Same as 0s for time-based animations.
• <time>: Duration in seconds (s) or milliseconds (ms).
• inherit: Inherits the value from the parent element.
• initial: Resets to the default value (0s).
• revert/revert-layer: Resets to the user agent’s default value.
• unset: Resets to the natural value.

Examples

Setting Animation Duration

Let’s create a simple animation that rotates a square.

HTML:

<div class="box"></div>

CSS:

.box {
  background-color: rebeccapurple;
  border-radius: 10px;
  width: 100px;
  height: 100px;
}

.box:hover {
  animation-name: rotate;
  animation-duration: 0.7s;
}

@keyframes rotate {
  0% {
    transform: rotate(0);
  }
  100% {
    transform: rotate(360deg);
  }
}

Multiple Animations

Let’s move a square horizontally and change its color with different durations.

HTML:

<div class="box"></div>

CSS:

.box {
  background-color: rebeccapurple;
  border-radius: 10px;
  width: 100px;
  height: 100px;
  animation-name: move, colorChange;
  animation-duration: 2s, 4s;
  animation-iteration-count: infinite;
}

@keyframes move {
  0% {
    transform: translateX(0);
  }
  100% {
    transform: translateX(200px);
  }
}

@keyframes colorChange {
  0% {
    background-color: rebeccapurple;
  }
  50% {
    background-color: steelblue;
  }
  100% {
    background-color: rebeccapurple;
  }
}

CSS Scroll-Driven Animations

For scroll-driven animations, animation-duration works differently.

HTML:

<div class="scroll-container">
  <div class="scroll-element">Scroll-driven animation</div>
</div>

CSS:

.scroll-container {
  height: 200vh; /* Make the container tall enough to scroll */
  position: relative;
}

.scroll-element {
  position: sticky;
  top: 50%;
  transform: translateY(-50%);
  text-align: center;
  font-size: 2rem;
  opacity: 0;
  animation-name: fadeIn;
  animation-duration: 1ms;
  animation-timeline: scroll();
  animation-fill-mode: forwards;
}

@keyframes fadeIn {
  0% {
    opacity: 0;
  }
  100% {
    opacity: 1;
  }
}

Related Properties

The animation-duration property is a key part of CSS animations, and it works with other properties to create amazing effects. Here are some related properties you can use to make your animations even better:

1. animation: This shorthand property lets you set multiple animation properties at once, including animation-name, animation-duration, animation-timing-function, animation-delay, animation-iteration-count, animation-direction, animation-fill-mode, and animation-play-state.
2. animation-name: Specifies the name of the keyframes animation to apply. This property is essential for defining the animation sequence.
3. animation-timing-function: Defines the speed curve of the animation. It controls how the animation speeds up and slows down over its duration.
4. animation-delay: Specifies the delay before the animation starts. This property is useful for staggering animations.
5. animation-iteration-count: Sets the number of times an animation cycle should be played. You can specify a number or use infinite for continuous playback.
6. animation-direction: Defines the direction of the animation. It can be set to normal, reverse, alternate, or alternate-reverse.
7. animation-fill-mode: Determines how a CSS animation applies styles before and after it is executing. Values include none, forwards, backwards, and both.
8. animation-play-state: Allows you to pause and resume animations. This property can be set to running or paused.
9. animation-timeline: Specifies the timeline for the animation. This property is particularly useful for scroll-driven animations.
10. animation-composition: This newer property allows you to composite multiple animations together, providing more control over how animations interact with each other.

By understanding and using these related properties, you can create sophisticated and engaging animations that enhance the user experience on your website. Each property plays a crucial role in defining the behavior and appearance of your animations, allowing you to create dynamic and interactive web designs.
