what is spinkit fr?

SpinKit is a collection of animated loading indicators, the spinning or pulsing shapes that appear on a website while content is loading, built entirely with CSS. The problem it solves is that creating smooth, good-looking loading animations from scratch is surprisingly time-consuming, and many developers reach for JavaScript-based solutions or heavy GIF images instead. SpinKit provides a set of ready-made, lightweight animations that require no JavaScript and no images. Each spinner is a small HTML snippet paired with CSS that uses only the "transform" and "opacity" properties to animate, keeping the animations smooth and hardware-accelerated. Available styles include Plane, Chase, Bounce, Wave, Pulse, Flow, Swing, Circle, Grid, Fold, and Wander. You add the CSS file to your project, copy a few lines of HTML, and the spinner appears. Color and size are controlled with CSS variables, specifically --sk-color and --sk-size, making customization straightforward. Spinners are self-contained with no shared classes, so you can copy just the code for the one animation you need. You would use SpinKit any time you are building a website or web app and need a polished loading indicator without the overhead of a full animation library. The tech stack is pure CSS.
