Create shimmer/skeleton loading animations by adjusting base color, highlight color, speed and direction. Preview in real-time and copy CSS code.
Shimmer effects are commonly used as loading placeholders to provide visual feedback.
A shimmer effect uses CSS linear gradient background with enlarged background-size and @keyframes to move background-position, creating a highlight sweep animation.
Use will-change: transform or contain: layout to optimize rendering. Remove shimmer elements after content loads.
