CSSanimointi

CSSanimointi, or CSS animation, refers to the process of creating animated visual effects using Cascading Style Sheets. It allows web developers to animate elements on a web page without the need for JavaScript or other scripting languages, relying solely on CSS properties. This makes animations more efficient and accessible.

The core of CSS animation lies in two main components: keyframes and animation properties. Keyframes define the stages of an animation, specifying CSS property values at different points in time. These points are typically expressed as percentages of the animation duration, with 0% representing the start and 100% representing the end. The `animation` property, or its individual sub-properties like `animation-name`, `animation-duration`, `animation-timing-function`, and `animation-iteration-count`, is then used to apply these keyframes to an HTML element and control how the animation plays out.

Common uses for CSS animations include adding subtle transitions to user interface elements, creating loading spinners, animating elements as they enter the viewport, and providing visual feedback for user interactions. Benefits include improved performance, better browser compatibility, and easier maintenance compared to JavaScript-based animations for simpler effects. However, for complex, interactive, or physics-based animations, JavaScript frameworks might still be preferred. CSS animations offer a powerful and efficient way to enhance user experience and add visual appeal to websites.
