Can I use multiple pulsing rings?

Yes. The generator automatically calculates staggered 'animation-delay' offsets across pseudo-elements and child spans for smooth, continuous wave propagation.

Understanding Your Results

Generates cross-browser optimized CSS @keyframes and HTML markup for concentric pulsing rings, opacity falloff, and glowing core indicators.

Practical Guidance & Next Steps

Use GPU-accelerated properties (transform: scale() and opacity) rather than width/height to guarantee stutter-free 60 FPS animations on mobile devices.

What is this?

A CSS code generator that builds tactical radar pulses, expanding sonar waves, and live beacon animations using hardware-accelerated CSS keyframes.

How does it work?

1. Choose beacon theme (Tactical Emerald, Radar Cyan, Warning Amber, Crimson Alert, or Neon Purple). 2. Customize ring count, pulse duration, maximum expansion scale, and core size. 3. Preview live animation and copy ready-to-use HTML and CSS.
