🔥 In Part 12 of the Mastering CSS series, we craft a sleek Shimmering Loader Effect — a modern, skeleton-style loading animation that mimics content loading states using only HTML and CSS.

✅ What you’ll learn in this video:
✔️ Structuring placeholder elements to represent text, images, or cards
✔️ Creating a shimmering effect using @keyframes, linear-gradient, and background-position
✔️ Applying animation and background-size for fluid motion
✔️ Making the shimmer reusable across different UI components
✔️ Designing responsive skeleton loaders for various screen sizes

💡 Why the Shimmering Loader Effect Matters:
🔹 Enhances perceived performance by showing structured placeholders
🔹 Delivers a polished, professional look seen in top apps and platforms
🔹 Helps users feel engaged during async data loading
🔹 JavaScript-free — optimized for speed and simplicity
