You're tasked with creating a spinner loader animation that rotates 360 degrees indefinitely. How would you define this in the @keyframes rule?

To create a spinner loader animation that rotates 360 degrees indefinitely, you would define it using the @keyframes rule. The correct definition uses Option 2: @keyframes rotate { 0% { transform: rotate(0deg); } 100% { transform: rotate(360deg); } }. This specifies a continuous rotation animation starting from 0 degrees and ending at 360 degrees, creating an infinite spinning effect.
