CSS Animation Overview

CSS animations allow you to create dynamic transitions and effects on web pages without the need for JavaScript. This guide provides an introduction to the fundamental concepts of CSS animations, helping you enhance user experience through engaging visual effects.

Key Concepts

1. Animation Properties

• @keyframes: Defines the sequence of frames for the animation.
• animation-name: Specifies the name of the keyframes to be used.
• animation-duration: Sets the time over which the animation occurs.
• animation-timing-function: Describes how the animation progresses over time (e.g., linear, ease-in).
• animation-delay: Specifies a delay before the animation starts.
• animation-iteration-count: Determines how many times the animation will play.
• animation-direction: Controls whether the animation plays forward, backward, or alternates.
• animation-fill-mode: Specifies how styles are applied before and after the animation.

2. Creating an Animation

• Use the @keyframes rule to define the animation.
• Apply the animation properties to the target element.

Example

CSS
@keyframes slide {
    from {
        transform: translateX(0);
    }
    to {
        transform: translateX(100px);
    }
}

.box {
    width: 100px;
    height: 100px;
    background-color: blue;
    animation-name: slide;
    animation-duration: 2s;
    animation-timing-function: ease-in-out;
    animation-iteration-count: infinite;
}

3. Using Animation

• To use the defined animation, apply the animation properties to the desired element.
• CSS animations can be combined with transitions for more complex effects.

Conclusion

CSS animations are a powerful tool for enhancing user experience on the web. By understanding the key properties and how to define animations using @keyframes, beginners can easily create engaging visual effects. Experiment with different properties to see how they affect animations!
