Animations with Keyframes in CSS: Life to Your Website

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.

What 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.

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.
