Bounce Particles around a Website

How to make particles interact with any HTML element on a website? We can do it with a help of a simple collision detection formula and a built-in JavaScript .getBoundingClientRect method. Let's discover more particle effects and creative coding experiments.

One of the simpler forms of collision detection is between TWO RECTANGLES that are axis aligned, they are not rotated. The algorithm works by ensuring there is no gap between any of the 4 sides of the rectangles. Let me show you the formula, explain it line by line and apply it in a real project.

Create beautiful particle systems with HTML5, CSS3 and plain vanilla JavaScript, no frameworks and no libraries. Understanding how the code works will allow us to transform this codebase into multiple very different effects. Let's explore the basic techniques and then take them to the limits in this particle effects crash course.
