CodePen is a great place to find inspiration and see what crazy UI experiments others are coming up with. As well as this, it’s also a useful place to find educational content. In this roundup we’ll explore some cool examples of CodePens that teach us all about web animation.

1. How Keyframes Work

This CodePen illustrates how browsers read through the sequence of steps in a keyframe animation.

2. Performant CSS Animation for Beginners

When we animate with CSS we have a vast array of properties to animate. However, not all are a good idea. Animating the wrong properties can make for slow, janky animations. This example from Ian Hazelton explains how the most efficient four properties work.

3. Keyframes Animation Demo

Sometimes a simple example is all you need. This example shows how the from and to syntax can be used in a simple keyframe.

4. requestAnimationFrame Demo

In this JavaScript demo from Matt West, see how the requestAnimationFrame API can be used to play and pause.

5. How to ChartJS

A great use of inline comments that demonstrate how to create two animated charts using ChartJS.

6. HTML5 Canvas Guide for Beginners

A nicely commented guide to using Canvas, by Petr Tichy.

7. Convert GIF to CSS Animations

Sometimes you don’t need a rendered GIF to get a fancy animation effect. These CSS-only examples from Joey Cheng are a useful example of what’s possible.

8. animateTransform Examples

Chris Coyier demonstrates how to use SVG’s animateTransform.

9. CSS Transforms: 3D Example and TransitionEnd

It’s often useful to know when an animation has finished. This simple demo shows how we can use JavaScript to tell when an animation ends.

10. Switching Animation Keyframes in Media Queries

Another great one to bookmark–this example shows how we can change animations using media queries. Resize the screen to see the effect!

Bonus: CSS Motion Paths

Lastly, let’s glimpse into the future of SVG animation with this demo showing how the motion-path property allows us to create complex paths of motion for our animations.

That’s a Wrap!

These are just a handful of the demos, blogs and walkthroughs available on CodePen. CodePen isn’t just great for animation though; try searching and you’ll find all sorts of great info and demos covering all manner of web development topics. Explore, learn, and have fun!
