Loading indicators tell users that something is happening in the background. A pulsing ring loader is a clean, modern way to show activity without taking up much space.
In this challenge, you will build a Pulsing Loader Ring — a centered circular animation with expanding rings that pulse outward infinitely. The rings should start small, grow larger, and fade out, creating a radar-like scanning effect.
Use CSS @keyframes to animate the scale and opacity of each ring. Add multiple rings with staggered animation delays so they pulse one after another.
