#176: Working with Framer Motion

Matt Perry from Framer and I take a look at the React animation library Framer Motion.

First, we take a look at how simple the API is. You control everything very declaratively through props on elements in your JSX. Controlling animation at this layer is very intuitive and connected to the UI and state in a meaningful way.

Each example we look at is more real-world and involves more features of what Framer Motion is capable of. React developers … Read article

Let’s Make a Fancy, but Uncomplicated Page Loader

It’s pretty common to see a loading state on sites these days, particularly as progressive web apps and reactive sites are on the rise. It’s one way to improve "perceived" performance — that is, making it feel as though the site is loading faster than it actually is.

There’s no shortage of ways to make a loader — all it takes is a quick search on CodePen to see oodles of examples, from animated GIFs to complex animations. While it’s … Read article

Ghost Buttons with Directional Awareness in CSS

It would surprise me if you'd never come across a ghost button 👻. You know the ones: they have a transparent background that fills with a solid color on hover. Smashing Magazine has a whole article going into the idea. In this article, we’re going to build a ghost button, but that will be the easy part. The fun and tricky part will be animating the fill of that ghost button such that the background fills up in the direction … Read article

Bounce Element Around Viewport in CSS

Let's say you were gonna bounce an element all around a screen, sorta like an old school screensaver or Pong or something.

You'd probably be tracking the X location of the element, increasing or decreasing it in a time loop and — when the element reached the maximum or minimum value — it would reverse direction. Then do that same thing with the Y location and you've got the effect we're after. Simple enough with some JavaScript and math. … Read article

CSS Animation Libraries

There are an awful lot of libraries that want to help you animate things on the web. These aren't really libraries that help you with the syntax or the technology of animations, but rather are grab-and-use as-is libraries. Want to apply a class like "animate-flip-up" and watch an element, uhhh, flip up? These are the kind of libraries to look at.

I wholeheartedly think you should both 1) learn how to animate things in CSS by learning the syntax yourself … Read article

Animating with Clip-Path

clip-path is one of those CSS properties we generally know is there but might not reach for often for whatever reason. It’s a little intimidating in the sense that it feels like math class because it requires working with geometric shapes, each with different values that draw certain shapes in certain ways.

We’re going to dive right into clip-path in this article, specifically looking at how we can use it to create pretty complex animations. I hope you’ll see just … Read article

Reduced Motion Picture Technique, Take Two

Did you see that neat technique for using the <picture></picture> element with <source media=""/> to serve an animated image (or not) based on a prefers-reduced-motion media query?

After we shared that in our newsletter, we got an interesting reply from Michael Gale:

What about folks who love their animated GIFs, but just didn’t want the UI to be zooming all over the place? Are they now forced to make a choice between content and UI?

I thought … Read article

Integrating Third-Party Animation Libraries to a Project

Creating CSS-based animations and transitions can be a challenge. They can be complex and time-consuming. Need to move forward with a project with little time to tweak the perfect transition? Consider a third-party CSS animation library with ready-to-go animations waiting to be used. Yet, you might be thinking: What are they? What do they offer? How do I use them?

Well, let’s find out.… Read article

Revisiting prefers-reduced-motion, the reduced motion media query

Two years ago, I wrote about prefers-reduced-motion, a media query introduced into Safari 10.1 to help people with vestibular and seizure disorders use the web. The article provided some background about the media query, why it was needed, and how to work with it to avoid creating disability-triggering visual effects.

The article was informed by other people’s excellent work, namely Orde Saunders’ post about user queries, and Val Head’s article on web animation motion sensitivity. … Read article
