Frequently Asked Questions

What is a CSS loader? +

A CSS loader (also called a spinner or loading indicator) is a pure CSS animation that shows users content is loading. Using CSS instead of GIFs gives you smaller file sizes, smoother animations, and easy customization.

How do I center a CSS spinner on the page? +

Use flexbox: add display:flex; justify-content:center; align-items:center; height:100vh; to the container. Or use position:fixed with top:50%; left:50%; transform:translate(-50%,-50%) on the loader itself.

What animation properties are used in CSS loaders? +

@keyframes defines the animation frames. animation sets the name, duration, iteration count (infinite), and timing function. transform:rotate() creates spinning, and opacity changes create pulse effects.

Can I use these CSS loaders in React or Vue? +

Yes — copy the CSS into your stylesheet and the HTML into your component. In React, convert class to className. For Vue, use the HTML directly in your template.

What is the performance impact of CSS animations? +

CSS animations using transform and opacity are GPU-accelerated and have minimal performance impact. Avoid animating properties like width, height, top, or left as they trigger layout reflows and are more expensive.
