Creating distraction-free reading experiences — Adrian Zumbrunnen

It’s our job as designers to bring clarity back to the digital canvas by crafting reading experiences that put readers first.

The Layouts of Tomorrow | Max Böck - Frontend Web Developer

A walkthrough of the process of creating a futuristic interface with CSS (grid and animation).

While this is just one interpretation of what’s possible, I’m sure there are countless other innovative ideas that could be realized using the tools we have today.

Lazy Loading Images and Video  |  Web Fundamentals  |  Google Developers

Jeremy Wagner offers a deep dive into lazy loading images (and video) with some advice for considering the no-JavaScript situation too.

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?

russellgoldenberg/scrollama: Scrollytelling with IntersectionObserver.

This looks like a handy JavaScript library for scroll-based events. But “scrollytelling?” No. Just …no.

One more reason not to use sticky headers on mobile.

thebaer/MMRA: Make Medium Readable Again — a browser extension

I’ve gotten a little tired of showing up to a Medium-powered site on a non-medium.com domain and getting badgered to Sign Up! or Get Updates! when I’m already a Medium user.

A Chrome extension to Make Medium Readable Again by:

• Keeping the top navigation bar from sticking around
• Hiding the bottom “Get Updates” bar completely
• (Optionally) hiding the clap / share bar
• (Optionally) loading all post images up front, instead of lazy loading as you scroll

Shame there isn’t a mobile version to get rid of the insulting install-our-app permabutton.

Sticky headers

A three-part series by Remy looking at one interface pattern (a sticky header) and how his code evolved and changed:

1. Sticky headers
2. Smooth scroll & sticky navigation
3. CSS sticky nav & smooth scroll

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.

Short note on improving usability of scrollable regions

Three very easy to implement additions to scrollable areas of your web pages: tabindex="0", role="region", and an aria-label attribute.

ScrollReveal

A nice self-contained script for animating items into view as the document scrolls.

I’d like be interested to hear what Graham thinks of this code—he’s my go-to person for smooth scroll-based animations.

(I’m very confused by the tagline for ScrollReveal—”Easy scroll animations for web and mobile browsers”—eh? Mobile browsers are web browsers …”web” is not a synonym for “desktop”.)

Interactive Storytelling | Codrops

I think this might be the most tasteful, least intrusive use of scroll events to enhance a Snowfallesque story. It’s executed superbly.

You can read all about the code. Interestingly, it’s using canvas to render the maps even though the maps themselves are being stored as SVG.

(There’s a caveat saying: “This is a highly experimental project and it might not work in all browsers. Currently there is no IE support.” I don’t think that’s true: the story works just in IE …that browser just doesn’t get the mapping enhancements.)

Troubleshooting rendering performance issues - YouTube

Harry packs a lot of great tips and tricks into one short video about performance troubleshooting. It’s also a great lesson in unlocking some handy features in Chrome’s developer tools.

Great stuff!

A look at detecting, pinpointing, measuring, and fixing rendering performance issues.

Native Scrolling by Anselm Hannemann

This gets nothing but agreement from me:

For altering the default scroll speed I honestly couldn’t come up with a valid use-case.

My theory is that site owners are trying to apply app-like whizz-banginess to the act of just trying to read some damn text, and so they end up screwing with the one interaction still left to the reader—scrolling.

There is no fold.

There.

Is.

No.

Fold.

Pure CSS parallax scrolling websites | Keith Clark

This is clever: a way to achieve parallax scrolling without JavaScript—much more performant.

Of course, you might want to ask yourself why you want a parallax effect in the first place.

The Sticky Pagination Fixer

If you insist on having a fixed header on your site, please, please, please add this script to your site. I often use the spacebar to page down so this would be a life-saver.

Scrolling is easier than clicking

This observation by Josh seems obvious in hindsight (all the best insights do), but there’s a powerful idea there:

So here is the real difference: scrolling is a continuation; clicking is a decision. Scrolling is simply continuing to do what you’re currently doing, which is typically reading. Clicking, however, is asking the user to consider something new…is this new thing the same as what I’m already doing, or something new?
