Blinkit Christmas Section Animation

This interaction showcases a seasonal Christmas-themed header in a grocery delivery app. As the search bar's placeholder text automatically cycles through relevant keywords (like 'rice', 'cookies', 'sweets', and 'disposables') using a slide-up crossfade, the promotional banner directly below it transitions in sync. The banner alternates between a row of festive gift boxes, a stylized 'MERRY CHRISTMAS' greeting, and co-branded sponsor logos. These elements slide vertically using smooth masking and springy easing, creating a cohesive and delightful seasonal atmosphere.
