Flat Design Horizontal Shape Expansion Animation

A solid yellow, irregular rectangular shape with small black dots animates from a compact, rounded form, smoothly expanding horizontally across the frame before contracting back to its initial size. This animated clip features a clean flat design aesthetic with a solid color palette and simple circular accents, providing a minimalist and modern visual tone. Its gentle, fluid expansion and contraction make it a versatile asset for understated transitions, as a dynamic background element, or to subtly introduce information in explainer videos, presentations, or digital interfaces that require a touch of soft, expanding motion.
