  • Understand how to connect (or map) inputs to outputs in JavaScript
  • Understand the theory behind Parallax


With JavaScript, HTML & CSS

You know what parallax is right? It’s that awesome 3D effect we’ve seen in tons of websites, games and apps (like Alto's Adventure for example). Parallax is an interaction delight and it attracts people like crazy. It may appear like voodoo and dark magic, but it’s actually pretty simple to code yourself! In this class I’m going to peel back the illusion that parallax is and show you how to start making interactive web pages with JavaScript.

You'll learn to create an interactive illusion of depth – where items further away move at a slower speed than items that are closer. And you’ll learn to make everything respond to a user's movement, like when the mouse moves or when the page scrolls.

The class is designed for someone with a basic knowledge of HTML, CSS + JavaScript. I do have some beginner classes on HTML + CSS and JavaScript that should get you up to speed.

Throughout this class, we'll cover:

  • Listening for user input (mouse movement and scroll position changes).

  • Connecting element properties like position, blur, and scale to user input.

  • Creating life-like illusions.

  • JavaScript principles.
