Making Animations Wait

I recently launched a CSS animation course for designers and developers wanting to improve their web animation skills. While building the course, I ran into the issue where content would animate before assets had downloaded. This article covers the approach I put together to fix the problem and ensure all animations played when expected.

Building Performant Expand & Collapse Animations

It's starting to be pretty common knowledge that there are only 2 things you can animate cheaply in CSS: opacity and transforms. Anything else, you run a high risk of that animation/transition being choppy. Fortunately, there is a ton of animation possibility with those properties, especially since transform can move and resize elements any-which-way.

You can even get tricky and fake the animating of other properties with transforms. In this tutorial on the Google Chrome Developers Blog, Paul Lewis and Stephen McGruer explain how you can use a vertical scale transform to fake a height animation, while simultaneously triggering a vertical scale transform the other direction so nothing looks squished.

It's clever, performant, and useful. I moved a copy to CodePen to play with.

It sure is a bunch of code for such a simple result, though. What I'd prefer to do as a developer is just have that click toggle a class, and the menu animate to an auto dimension, and have it all happen performantly.

Creating a Book Cover Using JavaScript and p5.js

I recently published a book and an interactive course called Coding for Visual Learners. It teaches coding to beginners from scratch using the widely popular JavaScript programming language and the p5.js programming library. Since p5.js a great and an easy to use drawing library, I wanted to make use of it to create the cover of my book and course as well. This is a tutorial on how to create this particular visual using JavaScript and p5.js.

An Animated Intro to RxJS

You might have heard of RxJS, or ReactiveX, or reactive programming, or even just functional programming before. These are terms that are becoming more and more prominent when talking about the latest-and-greatest front-end technologies. And if you're anything like me, you were completely bewildered when you first tried learning about it.

An Introduction to the Reduced Motion Media Query

The open web's success is built on interoperable technologies. The ability to control animation now exists alongside important features such as zooming content, installing extensions, enabling high contrast display, loading custom stylesheets, or disabling JavaScript.

Sites all too often inundate their audiences with automatically playing, battery-draining, resource-hogging animations. The need for people being able to take back control of animations might be more prevalent than you may initially think.

Intro to Vue.js: Animations

This is the fifth part in a five-part series about the JavaScript framework, Vue.js. In this last part of the series, we'll cover Animations (if you know me at all, you probably knew this was coming). This is not intended to be a complete guide, but rather an overview of the basics to get you up and running so you can get to know Vue.js and understand what the framework has to offer.

Web Animation Workshops in Spring

Web Animation Workshops has started up again for Spring, we're headed for San Francisco, Chicago, and Paris this year, some dates still to be announced. Val Head and I team up to bring you two packed days full of content and exercises so that when you leave the class, you not only understand the techniques of how to animate in different tech stacks/environments but why. Here's is some of the content we cover:
