Creating Custom Cursor Animations with JavaScript and Lerp

Modern web design relies on subtle, interactive details to engage visitors. Adding a smooth, custom cursor using linear interpolation (Lerp) is a powerful way to make your websites feel polished and responsive. In this course, you will learn how to design, code, and optimize custom cursor animations from scratch. By reading through structured explanations and analyzing clean code snippets, you will understand how to implement fluid motion that responds gracefully to user input. What you'll learn: Understand the fundamental math behind linear interpolation (Lerp) for smooth movement; Build custom cursor elements using HTML, CSS, and vanilla JavaScript; Implement high-performance rendering loops using requestAnimationFrame; Apply CSS transitions and transforms to enhance interactive hover states; Configure accessibility features to respect user preferences like reduced motion. You will start with the foundational concepts of coordinate systems and mathematical interpolation before moving on to practical implementation and performance optimization techniques. This text-based guide is designed for beginner to intermediate web developers who want to improve their front-end interaction skills, with no advanced prerequisites required. Start reading today to bring fluid, interactive animations to your web projects.
