CSS transition Property

The transition property creates animations.

It does this by changing property values over a period of time.

transition is a shorthand for several other transition properties.



An element with a transition.
Hovering over the rectangle will animate it into a circle.

  .transition {
    width: 150px;
    height: 150px;
    background-color: orangered;
    cursor: pointer;
    transition: border-radius 500ms ease;

  .transition:hover {
    border-radius: 50%;

<div class="transition"></div>

Using transition

The transition property creates CSS animations.

The transition is a shorthand for these properties:

Transitions occur when a property value changes from one value to another.

This will create an step-wise animation over a specified time span.

If no transition-property is provided, the transition will be applied to all animatable properties.


transition: property duration timing-function delay | 
            initial | inherit;



Value Description
transition-property Transition property name
transition-duration Time (seconds or milliseconds) the transition takes to complete
transition-timing-function The easing function for the transition
transition-delay Delay (seconds or milliseconds) before the transition starts
initial Sets the value to its default value.
inherit Inherits the property from its parent element.
