This CSS animation defines a smooth looping motion that makes a box appear to travel around the edges of a square container while changing its shape dynamically at each corner. The @keyframes move sequence adjusts the width, height, margins, and border-radius of the box to simulate rounded transitions and smooth corner turns. As the animation progresses through key stages (12.5%, 25%, 37.5%, etc.), the box stretches horizontally or vertically and rounds specific corners to give a flowing, fluid effect. When combined with the .animate-move class, this animation brings a lively geometric movement that feels both mathematical and elegant—perfect for visually engaging loaders, UI highlights, or modern motion effects.
