Visual interaction on web pages has come a long way from simple hover effects to complex animations that capture attention and improve the user experience. CSS, which has always been the backbone of web design, offers us a powerful tool to create these interactions: animations using @keyframes
. Next, I will guide you step by step in using @keyframes
to breathe life into your web pages with dynamic and captivating animations.

ToggleWhat Are Keyframes in CSS?
Directive @keyframes
It is the essence of CSS animations. With it, we can specify the points over time of how we want the properties of an HTML element to transform. Imagine that keyframes are photographs on a timeline of an animation, where each photo defines the state of your element at a specific moment.
Starting with @keyframes
Wear @keyframes
It is relatively simple. First, you need to define the animation points with an identifying name and then apply that animation to an element.
@keyframes my-animation { from { /* Initial state of the element */ } to { /* Final state of the element */ } } element { animation: my-animation 2s infinite; }
In the example, my-animation
will change the status of element
of desde
a to
in 2 seconds, and it will repeat indefinitely.
Controlling the Moments of your Keyframes
@keyframes
gives control of every moment of your animation. You are not limited to desde
y to
@keyframes my-dynamic-animation { 0% { /* Initial state */ } 50% { /* Intermediate state */ } 100% { /* Final state */ } }
Animatable Properties in CSS
Before you start animating, it's crucial to know what properties you can animate. Some of these include opacity
, transformation
, margin
, color
, etc. Not all properties are animatable, so it's best to check the CSS documentation to find out which ones you can use.
How to Sync Your Animations
Animations can be configured to run at different times and have different durations. The property animation-delay
can delay the start of an animation, while animation-duration
specifies how long it lasts. Varying these values can help you sync multiple animations or create sequential effects.
Advanced Effects with animation-timing-function
This property controls the acceleration of the animation. Do you want your animation to start slow and finish fast? Use a function ease-out
. There are several predefined functions, but you can also create your own with cubic-bezier
.
Animation Iterations and Direction
You can make an animation run a certain number of times or make it infinite with animation-iteration-count
. With animation-direction
, you can even make an animation move backward or alternate between moving forward and backward.
Optimizing the Performance of your Animations
Complex animations can affect performance, especially on devices with less processing power. Use properties like transformation
y opacity
It is preferable because they do not cause reflows or repaints that are intensive for the CPU. Also, always measure and test your animations to make sure they run smoothly.
Creative Examples with @keyframes
To inspire you, here are a series of examples that you can try and modify for your own projects.
Entry and Exit Animations
Use keyframes to make an element slide onto the screen or fade out smoothly. These types of animations are perfect for alerts or modals.
Hover Animations
Give dynamism to your buttons or links with animations that trigger when you hover over them. It can be a color change, a twist, or a subtle shift.
Chargers and Spinners
Instead of using GIF or SVG images, how about creating a spinner with just CSS? These loading indicators are great exercises to hone your keyframing skills.
Tools to Create CSS Animations
Nowadays, there are online tools that can help you visualize and generate the necessary code for your animations. Explore, test and adjust until you find the perfect animation.
