Understanding CSS Transitions: A Comprehensive Guide

In this tutorial, we will delve into the world of Cascading Style Sheets (CSS) and specifically focus on one of its most dynamic features – transitions. The transition property in CSS is a powerful tool that allows you to smoothly change property values over a given duration.

What is Transition Property?

The transition-property in CSS specifies the name or names of the CSS properties to which transitions should be applied. This means you can control which properties will have an animated effect upon changing.


    transition-property: none|all|property|initial|inherit;

Transition Duration

The ‘transition-duration’ property defines the length of time that a transition will take from start to end. It’s usually defined in seconds (s) or milliseconds (ms).


    transition-duration: time|initial|inherit;

Transition Delay

The ‘transition-delay’ property specifies when the transition effect will start. It allows for a delay between when a property changes and when the transition starts.


    transition-delay: time|initial|inherit;

Transition Timing Function

The ‘transition-timing-function’ property describes how intermediate property keyframes are calculated, allowing for effects such as acceleration or slowing down during the animation.


    transition-timing-function: linear|ease|ease-in|
    step-end|steps(int,start | end)|cubic-bezier(n,n,n,n)|initial | inherit;

Putting It All Together

You can use all these properties individually, but for brevity and convenience, CSS provides the ‘transition’ shorthand property. Here’s how you can use it:


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


    div {
        transition: width 2s linear 1s;

In this example, the div’s width will change over a period of 2 seconds in a linear fashion after a delay of 1 second.


CSS transitions provide an easy way to animate changes on your web pages. By understanding and using the transition-property, transition-duration, transition-delay, and transition-timing-function properties effectively, you can create visually appealing websites that enhance user experience.
