CSS Transitions let you create smooth and eye-catching animations by smoothly changing CSS properties over a specific time period. Whether you want to add elegance when hovering over an element or make it pop when a class is applied, CSS Transitions have covered you.
Using CSS Transitions is totally effortless. You need to specify the transition properties, such as duration, timing function, and delay, in the CSS rule for the element you want to animate. You can animate various properties like colors, sizes, positions, opacity, etc.
When a property change happens, the transition kicks in and smoothly takes your element from its original state to the new state. You control the transition's speed and style through the timing function. Want a snappy acceleration or a gentle deceleration? It's all up to you!
With CSS Transitions, you can easily bring your web elements to life. They add that extra touch of interactivity and visual appeal, making your website or web application more engaging and delightful for users.
So, let's go ahead and learn how to add some CSS Transition magic into your projects for an interactive UI!

What are CSS Transitions?
CSS Transitions are a CSS feature that enables smooth animations and transitions between different states of an element. They allow you to specify how an element should change over time when certain CSS properties are modified.
The transition is controlled by the duration, which determines how long the animation takes, and the timing function, which defines the pace of the animation. The delay property allows you to introduce a pause before the transition starts.
Cross-Browser Compatibility and Support for CSS transition
Cross-browser compatibility is important when using CSS Transitions to ensure consistent behavior and visual effects across different web browsers.
While CSS Transitions are widely supported by modern browsers, you should be aware of some differences in implementation and support. Here's an overview of cross-browser compatibility and support for CSS Transitions:
- W3C Standardization: CSS Transitions, included in the CSS3 standard established by the World Wide Web Consortium (W3C), are typically supported by contemporary web browsers, aligning with the universally accepted specifications.
- Modern Browser Support: CSS Transitions are widely supported by the latest iterations of commonly used web browsers such as Chrome, Firefox, Safari, and Edge. These browsers exhibit consistent behavior when it comes to CSS Transitions. To ensure compatibility, testing your transitions on these recommended browsers is advisable.
- Vendor Prefixes: Previously, various browser vendors utilized vendor prefixes (e.g., -WebKit-, -moz-) to implement experimental CSS features like Transitions. While the necessity for vendor prefixes in CSS Transitions has diminished in recent times, older browser versions might still rely on them. To ensure wider compatibility, especially with older browsers, it is advisable to include vendor prefixes as a good practice.
- Compatibility Testing: To guarantee compatibility across various browsers and their versions, it is essential to thoroughly test CSS Transitions. This can be achieved using browser testing tools. Alternatively, you can conduct tests on physical devices or virtual machines running different browsers.
CSS Transition Properties
CSS transitions offer a powerful toolset that allows you to control the duration, delay, timing function, and targeted properties of your web designs and captivating animations. We'll dive into the essential CSS transition properties and explore how you can use them to create visually appealing and engaging animations.
#1 CSS transition-property
Now, let's talk about the Transition-Property! With Transition-Property, you have the power to explicitly choose which properties you want to animate. You can be specific and target only the properties that need a touch of enchantment, saving your other properties from the transformation.
transition-property: width, height;
In this example, we have the
transition-property transition at work. It explicitly specifies that only the
height properties will experience the transformation. When the user hovers over the box, only the width and height properties will change, while the background-color remains untouched.
#2 CSS transition-duration
The transition-duration property in CSS allows you to specify the duration of a transition effect, determining how long the animation will take to complete. By setting a specific duration, such as 1 second (
1s) or 500 milliseconds (
500ms), you can control the speed at which the transition occurs.
Here's an example to demonstrate the usage of the transition-duration property:
transition-property: width, height;
transition-property property is used to specify that the
height properties of the
.box class will undergo a transition animation just like in the previous transition of
transition-property. This means that when these properties change, such as when the user hovers over the element, a smooth transition effect will be applied.
The "transition-duration" property is like the conductor of a CSS transition. It determines the length of time it takes for a transition to perform its magical animation.
transition-duration: 2s; sets the duration of the transition to 2 seconds. This means that whenever the width and height properties of the
.box element change, the transition will take a leisurely 2 seconds to smoothly transform from one state to another transition.
If you want a slower and more graceful transformation, you can increase the duration. For a quick and snappy change, a shorter duration will do the trick.
By adjusting with the
transition-duration property, you can play with the speed and timing of your transitions, creating captivating effects that perfectly suit your style. Just remember to find the right balance, so the duration is noticeable to users without making the transition feel like an eternity or disrupting their overall experience.
#3 CSS transition-delay
transition-delay property in CSS allows you to specify a pause or delay before a transition effect starts. It introduces a waiting period between the moment a CSS property changes and the beginning of the transition animation. By using the transition-delay property, you can create more dynamic and controlled effects by sequencing transitions or adding delays between them.
Here's an example to illustrate the usage of the transition-delay property:
transition-property: width, height;
Let's dive into the
transition-delay property! When you hover over the
.box element with the transition-delay property set to 2 seconds
2s, a moment of suspense unfolds before the transition effect kicks in.
As you hover over the
.box element the width property will gracefully transition from 200 pixels to 400 pixels, and the height property will undergo a transformation from 200 pixels to 300 pixels. The whole performance lasts for a 2 seconds.
But here's the twist! Before the transition starts, there's a playful pause of 2 seconds. This brief delay adds a touch of anticipation and excitement, making the animation feel purposeful and engaging.
By adjusting with the transition-delay property, you can craft experiences that build up anticipation and surprise. It's like giving your transitions their own dramatic entrance, ensuring they captivate your audience and create a lasting impression.
The transition-delay property works by adding a suspenseful 2-second pause before the width and height properties of the
.box element elegantly transition.
#4 CSS transition-timing-functions
Before continuing into how to use the
transition-timing-function property into your codes, we need to explore these transition timing functions.
This is the default transition timing function, and it's like the "smooth operator" of the bunch. It starts slowly, picks up speed in the middle, and then eases off towards the end. It creates a natural and graceful transition effect that flows seamlessly.
With this timing function, the transition progresses at a constant speed from start to end. It lacks the gradual acceleration and deceleration of other timing functions, resulting in a steady and consistent transition.
This timing function provides a slow start to the transition, gradually picking up speed as it progresses. It creates an effect where the transition seems to ease into the new state.
On the contrary, this timing function starts with a normal speed and then gradually slows down towards the end of the transition. It produces an effect where the transition seems to ease out of the current state.
This timing function combines the characteristics of both
ease-out. It starts with a slow start, accelerates in the middle, and then slows down towards the end. It creates a smooth and balanced transition that eases both into and out of the animation.
This cubic-bezier is also one of the timing function yet unique as it allows you to define your own custom values in a cubic-bezier function. The n values range from 0 to 1 and define the control points of a cubic Bézier curve. By adjusting these values, you can create unique and personalized timing functions, giving you complete control over the acceleration and deceleration of the transition. This enables you to create custom easing effects that match your design vision precisely.
Let's now continue with our transitions, by added a little something extra to make our transitions even more delightful. We've included the
transition-timing-function property, which allows us to create custom easing curves for our transition animation.
transition-property: width, height;
transition-timing-function: cubic-bezier(0.25, 0.1, 0.25, 1);
By specifying the cubic-bezier timing function and tweaking the control points (in this case, using the values 0.25, 0.1, 0.25, 1), we can design unique and captivating transitions. It's like having our very own control to the acceleration and deceleration of the animation. We can make it start slow, speed up, and then slow down again, all with a touch of creativity.
When the user hovers over our
.box element, the width gracefully transitions from 200px to 400px, and the height undergoes a change from 200px to 300px. The transition takes a delightful 2 seconds to complete. To top it off, the custom easing effect provided by the cubic-bezier timing function gives the animation its own unique personality, making it stand out from the crowd.
With this addition of the
transition-timing-function property and our carefully chosen cubic-bezier values, our
.box element truly comes to life. It's like adding a sprinkle of magic to the mix, enhancing the overall user experience and leaving a lasting impression. So get ready to bring your designs to the next level with these delightful and customizable transition effects.
#5 CSS transition - Shorthand Value
CSS Transition allows you to create super-smooth animations for multiple CSS properties in just one go. It's a handy shortcut that saves you from writing multiple lines of code. With the transition property, you can define the duration, timing function, delay, and the properties that will magically transform in your animation. It's like creating visually stunning and seamless transitions just with one property to access all the other within transition properties.
transition: width 1s ease-in-out, height 0.5s linear;
In this example, the
.box class has the transition property set
transition: width 1s ease-in-out, height 0.5s linear. It says that when the user hovers over the box, the width will gracefully transform from 200px to 400px over a magical 1-second duration with an enchanting ease-in-out timing function. Meanwhile, the height will transform from 200px to 300px, accompanied by a swift 0.5-second linear transition. It's like watching the box grow and shrink without giving the actual transitions one by one.
Note: By understanding the difference between CSS Transition and CSS Transition-Property, you can use your CSS transition wisely. Whether you want to use transition on multiple properties or specifically choose properties for transformation with the transition-property for your designs.
CSS Triggering Transitions
Triggering transitions involves the event or action that starts the transition animation on an element. It determines when the transition effect should take place, like when a user interacts with the element or when specific conditions are fulfilled.
Here are some triggers where you can use CSS transitions:
When the user hovers over an element, it can trigger transitions that smoothly change its color, size, or other visual properties. For example, imagine a button that gracefully transitions to a different color when the user hovers over it. It adds a delightful touch to the user experience.
Clicking on an element can also trigger transitions. This is often used for interactive elements like menus or dropdowns. For instance, when a user clicks on a menu item, the menu can smoothly transition to reveal additional sub-items, creating a seamless navigation experience.
Transitions can be triggered when the page or specific elements finish loading. This is perfect for creating entrance animations or revealing content gradually to capture the user's attention. Imagine elements fading in or sliding into view as the page loads, creating an enticing experience.
#5 Time-based Triggers
As the user scrolls the page, transitions can be triggered based on scroll events. This allows elements to gracefully come into view or change their appearance depending on their position in the viewport. It's a powerful way to add depth and interactivity to a webpage.
