CSS Transitions

CSS Transitions

CSS transitions allows you to change property values smoothly, over a given duration.

 Mouse over the element below to see a CSS transition effect:


In this chapter you will learn about the following properties:

  • transition
  • transition-delay
  • transition-duration
  • transition-property
  • transition-timing-function

Browser Support for Transitions

The numbers in the table specify the first browser version that fully supports the property.

transition 26.0 10.0 16.0 6.1 12.1
transition-delay 26.0 10.0 16.0 6.1 12.1
transition-duration 26.0 10.0 16.0 6.1 12.1
transition-property 26.0 10.0 16.0 6.1 12.1
transition-timing-function 26.0 10.0 16.0 6.1 12.1

How to Use CSS Transitions?

To create a transition effect, you must specify two things:

  • the CSS property you want to add an effect to
  • the duration of the effect

Note: If the duration part is not specified, the transition will have no effect, because the default value is 0.

The following example shows a 100px * 100px red <div> element. The <div> element has also specified a transition effect for the width property, with a duration of 2 seconds:


div {
  width: 100px;
  height: 100px;
  background: red;
  transition: width 2s;

The transition effect will start when the specified CSS property (width) changes value.

Now, let us specify a new value for the width property when a user mouses over the <div> element:


div:hover {
  width: 300px;

Notice that when the cursor mouses out of the element, it will gradually change back to its original style.

Change Several Property Values

The following example adds a transition effect for both the width and height property, with a duration of 2 seconds for the width and 4 seconds for the height:


div {
  transition: width 2s, height 4s;

Specify the Speed Curve of the Transition

The transition-timing-function property specifies the speed curve of the transition effect.

The transition-timing-function property can have the following values:

  • ease - specifies a transition effect with a slow start, then fast, then end slowly (this is default)
  • linear - specifies a transition effect with the same speed from start to end
  • ease-in - specifies a transition effect with a slow start
  • ease-out - specifies a transition effect with a slow end
  • ease-in-out - specifies a transition effect with a slow start and end
  • cubic-bezier(n,n,n,n) - lets you define your own values in a cubic-bezier function

The following example shows some of the different speed curves that can be used:


#div1 {transition-timing-function: linear;}
#div2 {transition-timing-function: ease;}
#div3 {transition-timing-function: ease-in;}
#div4 {transition-timing-function: ease-out;}
#div5 {transition-timing-function: ease-in-out;}

Delay the Transition Effect

The transition-delay property specifies a delay (in seconds) for the transition effect.

The following example has a 1 second delay before starting:


div {
  transition-delay: 1s;
Try it Yourself »

Transition + Transformation

The following example adds a transition effect to the transformation:


div {
  transition: width 2s, height 2s, transform 2s;
Try it Yourself »

More Transition Examples

The CSS transition properties can be specified one by one, like this:


div {
  transition-property: width;
  transition-duration: 2s;
  transition-timing-function: linear;
  transition-delay: 1s;
Try it Yourself »

or by using the shorthand property transition:


div {
  transition: width 2s linear 1s;
Try it Yourself »

CSS Transition Properties

The following table lists all the CSS transition properties:

Property Description
transition A shorthand property for setting the four transition properties into a single property
transition-delay Specifies a delay (in seconds) for the transition effect
transition-duration Specifies how many seconds or milliseconds a transition effect takes to complete
transition-property Specifies the name of the CSS property the transition effect is for
transition-timing-function Specifies the speed curve of the transition effect
