Material Design Animation Guides

I’ve seen two guides posted to Medium about animation in the last month that have seriously blown up! Taras Skytskyi’s The ultimate guide to proper use of animation in UX Jonas Naimark’s Motion design doesn’t have to be hard There is a lot to learn in each one! The demonstration animations they use are wonderfully well done and each guide demonstrates an interesting and effective animation technique, often paired next to a less successful technique to drive the point home. They are both heavily focused on Material Design though, which is fine, but I think Val Head said it best: Google wrote material design for branding Google things. When you use material design on things that aren’t Google, you’re kind of using Google’s branding on a thing that is not Google, and that’s weird. Material design is Google’s opinion on motion. It’s Google’s branding opinion on motion. It’s not a de facto standard of how motion should happen. The post Material Design Animation Guides appeared first on CSS-Tricks....

Browser painting and considerations for web performance

The process of a web browser turning HTML, CSS, and JavaScript into a finished visual representation is quite complex and involves a good bit of magic. Here’s a simplified set of steps the browser goes through: Browser creates the DOM and CSSOM. Browser creates the render tree, where the DOM and styles from the CSSOM are taken into account (display: none elements are avoided). Browser computes the geometry of the layout and its elements based on the render tree. Browser paints pixel by pixel to create the visual representation we see on the screen. In this article, I’d like...

Page Transitions for Everyone

As Sarah mentioned in her previous post about page transition using Vue.js, there is plenty of motivation for designers and developers to be building page transitions. Let’s consider mobile applications. While mobile applications are evolving, more and more attention is given to the animation experience, while the web pretty much stays the same. Why is that? Maybe it’s because native app developers spend more time working on those animations. Maybe it’s because users say that’s what they want. Maybe it’s because they know more about the environment in which the app is going to run. All of that helps...

Simple Swipe With Vanilla JavaScript

I used to think implementing swipe gestures had to be very difficult, but I have recently found myself in a situation where I had to do it and discovered the reality is nowhere near as gloomy as I had imagined. This article is going to take you, step by step, through the implementation with the least amount of code I could come up with. So, let’s jump right into it! The HTML Structure We start off with a .container that has a bunch of images inside: ... Basic Styles We use display: flex to make sure images go alongside each other with no spaces in between. align-items: center middle aligns them vertically. We make both the images and the container take the width of the container’s parent (the body in our case). .container { display: flex; align-items: center; width: 100%; img { min-width: 100%; /* needed so Firefox doesn't make img shrink to fit */ width: 100%; /* can't take this out either as it breaks Chrome */ } } The fact that both the .container and its child images have the same width makes these images spill out on the right side (as highlighted by the red outline) creating a horizontal scrollbar, but this is precisely what we want: The initial layout (see live demo). Given that not all the images have the same dimensions and aspect ratio,...

What Houdini Means for Animating Transforms

I’ve been playing with CSS transforms for over five years and one thing that has always bugged me was that I couldn’t animate the components of a transform chain individually. This article is going to explain the problem, the old workaround, the new magic Houdini solution and, finally, will offer you a feast of eye candy through better looking examples than those used to illustrate concepts. The Problem In order to better understand the issue at hand, let’s consider the example of a box we move horizontally across the screen. This means one div as far as the HTML...

The Red Reveal: Illusions on the Web

In part one of a series of posts about optical illusions on the web, Dan Wilson looks at how to create the “Red Reveal” that he happens to describe like this: Growing up, my family played a lot of board games. Several games such as Outburst, Password, and Clue Jr. included something that amazed me at the time — a red lens and cards with some light blue text that was obscured by a myriad of red lines. When you put the red lens over the card, the text would magically appear. Here’s one example of that effect from...

Web Animation Workshops Dates for 2018 Announced

“I’m getting a raise!” This was my favorite quote from last year’s Web Animation Workshops, as Val and I covered performance, tooling, and creating animations for SVG, CSS, JS and React. Now we’re gearing up for another round of Web Animation Workshops in 2018! But we’re only offering two workshops this time since both of us have moved away from full-time consulting. The aim of these workshops is to level up your animation skills in just two days and equip you with a full understanding of animation concepts without having to rely on copying and pasting code from other people in your web applications. These are the dates and locations: Chicago: March 19 – 20 Brighton, UK: July 9 – 10 We’re already out of early bird tickets for Chicago and space is limited, so grab yours quickly before they sell out. We’ll see you there! Direct Link to Article — Permalink Web Animation Workshops Dates for 2018 Announced is a post from CSS-Tricks...

Robust React User Interfaces with Finite State Machines

User interfaces can be expressed by two things: The state of the UI Actions that can change that state From credit card payment devices and gas pump screens to the software that your company creates, user interfaces react to the actions of the user and other sources and change their state accordingly. This concept isn’t just limited to technology, it’s a fundamental part of how everything works: For every action, there is an equal and opposite reaction. – Isaac Newton This is a concept we can apply to developing better user interfaces, but before we go there, I want...

Creating Vue.js Transitions & Animations

My last two projects hurled me into the JAMstack. SPAs, headless content management, static generation… you name it. More importantly, they gave me the opportunity to learn Vue.js. More than “Build a To-Do App” Vue.js, I got to ship real-life, production-ready Vue apps. The agency behind Snipcart (Spektrum) wanted to start using decoupled JavaScript frameworks for small to medium sites. Before using them on client projects, however, they chose to experiment on themselves. After a few of my peers had unfruitful experiences with React, I was given the green light to prototype a few apps in Vue. This prototyping...
