HTML5 is taking over the browsers and one of the coolest things in HTML5 is the canvas - the immediate mode drawing surface you have in HTML for bringing pixels to life using JavaScript. It is used to create games, graphs, and animations.

This is an extensive course with interactive playgrounds (so you don't have to install anything). The course can be divided into four parts.

1. Understand basics of Canvas and compare it with DOM.
2. Learn how to draw shapes.
3. Take a deep dive into canvas transformations and animations.
4. Explore advanced mouse and keyboard handling to create truly interactive applications using canvas.

If none of what I just wrote makes sense, then the content here is just what you need 😀 . Let's get started.

HTML5 Canvas: From Noob to Ninja - an interactive deep dive

For displaying 2d visuals, sprite sheets are wildly popular. They are most commonly used in games, but as you saw here, you can also use sprite sheets to define normal (and boring) things. Now that you've seen how to implement an animation using a sprite sheet, it all seems pretty easy, right? All you do is just load your sprite sheet and use `drawImage` to display a frame of your sprite sheet at a time. The fun starts to happen when you have no control over the sprite sheets you have to work with. In those cases, your `drawImage` shifting logic might be more involved than just incrementing one variable by a fixed amount. Anyway, no need to worry about that now. When you get to that point, you'll know what to do. If not, just comment here or post on the forums, and I or somebody else will try to help you out :P
