A demo of page transition animations by Sarah—she’s written about how she did it. I really like it as an example of progressive enhancement: you can navigate around the site just fine, but with JavaScript you get the smooth transitions as a bonus.

All of this reminds me of Jake’s proposal for navigation transitions in the browser. I honestly think this would solve 80% of the use-cases for single page apps.

Parallax scrolling with CSS variables | basicScroll

Don’t let the title fool you—this isn’t just for parallax scrolling (thank goodness!)—it’s for triggering any CSS updates based on scroll position. Using CSS custom properties makes a lot of sense. The JavaScript/CSS bridge enabled by custom properties is kind of their superpower. (That’s one of the reasons why I don’t like calling them “CSS variables” which makes them sound like Sass variables—they’re so much more than that!)

Your Interactive Makes Me Sick - Features - Source: An OpenNews project

Browsers have had consistent scrolling behavior for years, even across vendors and platforms. There’s an established set of physics, and if you muck with the physics, you can assume you’re making some people sick.

Guidelines to consider before adding swooshy parallax effects:

  1. Respect the Physics
  2. Remember that We Call Them “Readers”
  3. Ask for Consent

Given all the work that goes into a powerful piece of journalism—research, interviews, writing, fact-checking, editing, design, coding, testing—is it really in our best interests to end up with a finished product that some people literally can’t bear to scroll through?

Electronic Items

I love the way Guillaume Kurkdjian uses animation here to demonstrate how these gadgets from the ’90s would work.

Scrolling on the web: A primer - Microsoft Edge Dev BlogMicrosoft Edge Dev Blog

A ludicrously deep dive by Nolan into how scrolling works in web browsers. No, wait, come back! It’s more interesting than it sounds …and it certainly isn’t as simple as you might think.

For instance, do you know the difference between the following scenarios?

  • User scrolls with two fingers on a touch pad
  • User scrolls with one finger on a touch screen
  • User scrolls with a mouse wheel on a physical mouse
  • User clicks the sidebar and drags it up and down
  • User presses up, down, PageUp, PageDown, or spacebar keys on a keyboard

If you ask the average web user (or even the average web developer!) they might tell you that these interactions are all equivalent. The truth is far more interesting.

This comes complete with lovely animated illustrations by Rachel.

A wonderful short story by Matt Webb, who is clearly still thinking about movement (his theme from Web Directions North earlier this year).
