What Is CSS Spinner Generator?

The CSS Spinner Generator creates animated loading indicators using pure CSS. Loading spinners provide visual feedback to users during asynchronous operations like data fetching, file uploads, or page transitions. This tool offers four distinct spinner styles: border spinner (classic rotating circle), dots (bouncing dots), pulse (expanding circle), and ring (rotating ring). Each style is fully customizable with controls for color, size, border width, and animation speed. The generated code includes both the HTML markup and the CSS with @keyframes animation definitions. All spinners are lightweight, performant, and require no JavaScript or external libraries. They work across all modern browsers and are easily integrated into any web project.

Why Use CSS Spinner Generator?

  • Four distinct spinner styles for different design contexts
  • Pure CSS with no JavaScript or library dependencies
  • Customizable size, color, speed, and border width
  • Generated code includes HTML and complete CSS with keyframes

Technical Guide

CSS spinners use @keyframes animations to create continuous motion. The border spinner technique uses a circular element with a transparent border on most sides and a colored border on one side, then rotates it 360 degrees. The dots animation uses scale transforms to create a bouncing effect with staggered animation-delay. The pulse animation scales an element from 0 to 1 while fading opacity. All animations use animation: name duration timing-function iteration-count. Setting iteration-count to infinite ensures continuous looping. The animation-timing-function (ease, linear, ease-in-out) controls the speed curve. For accessibility, add role="status" and an aria-label to spinners. Consider using prefers-reduced-motion media query to disable or reduce animations for users who prefer reduced motion.

Tips & Best Practices

  • 1
    Use animation-timing-function: linear for smooth, constant rotation
  • 2
    Add prefers-reduced-motion media query for accessibility
  • 3
    Keep spinner size appropriate—48px is standard, 24px for inline
  • 4
    Use aria-label="Loading" for screen reader accessibility

Frequently Asked Questions

Q Are CSS spinners accessible?
Yes — add role="status" and aria-label="Loading" to the spinner element, and respect prefers-reduced-motion preferences.
Q Can I change the rotation direction?
Yes, change the @keyframes from rotate(360deg) to rotate(-360deg) for counter-clockwise rotation.
Q How do I center the spinner on the page?
Use flexbox: display: flex; justify-content: center; align-items: center on the parent container.
Q Will CSS spinners work in older browsers?
CSS animations and border-radius are supported in IE10+ and all modern browsers.
Q How do I change the animation speed?
Adjust the animation duration value. Lower values (0.5s) make it faster, higher values (2s) make it slower.
