Designing for Progressive Disclosure by Steven Hoober

Progressive disclosure interface patterns categorised and evaluated:

• popups,
• drawers,
• mouseover popups (just say no!),
• accordions,
• tabs,
• new pages,
• scrolling,
• scrolling sideways.

I really like the hypertext history invoked in this article.

The piece finishes with a great note on the MacNamara fallacy:

Everyone thinks metrics let us measure results. But, actually, they don’t. They measure only what they are measuring. Engagement, for example, is not something that can be measured, so we use an analogue for it. Time on page. Or clicks.

We often end up measuring what is quick, cheap, and easy to measure. Therefore, few organizations regularly conduct usability testing or customer-satisfaction surveys, but lots use analytics.

Even today, organizations often use clicks as a measure of engagement. So, all too often, they design user interfaces to generate clicks, so the system can measure them.

Fixed Headers and Jump Links? The Solution is scroll-margin-top | CSS-Tricks

I didn’t know about scroll-margin-top! I wonder if you could apply a universal rule …like, say you’ve got a fixed header that’s 2em in height, couldn’t you declare:

:target { scroll-margin-top: 2em; }

WICG/ScrollToTextFragment: Proposal to allow specifying a text snippet in a URL fragment

Native lazy-loading for the web  |  web.dev

The title is somewhat misleading—currently it’s about native lazy-loading for Chrome, which is not (yet) the web.

I’ve just been adding loading="lazy" to most of the iframes and many of the images on adactio.com, and it’s working a treat …in Chrome.

8 DOM features you didn’t know existed - LogRocket Blog

If you ignore the slightly insulting and condescending clickbaity title, this is a handy run-down of eight browser features with good support:

1. extra arguments in addEventListener(),
2. scrollTo(),
3. extra arguments in setTimeout() and setInterval(),
4. the defaultChecked property for checkboxes,
5. normalize() and wholeText for strings of text,
6. insertAdjacentElement() and insertAdjacentText(),
7. event.detail, and
8. scrollHeight and scrollWidth.

Another take on the scrolling navigation pattern. However you feel about the implementation details, it’s got to better than the “teenage tidying” method of shoving everything behind a hamburger icon.

Accessibility for Vestibular Disorders: How My Temporary Disability Changed My Perspective · An A List Apart Article

This is a fascinating insight into what it’s like to use the web if you’ve got vertigo (which is way more common than you might think):

Really, there are no words to describe just how bad a simple parallax effect, scrolljacking, or even background-attachment: fixed would make me feel. I would rather jump on one of those 20-G centrifuges astronauts use than look at a website with parallax scrolling.

Every time I encountered it, I would put the bucket beside me to good use and be forced to lie in bed for hours as I felt the room spinning around me, and no meds could get me out of it. It was THAT bad.

The scrollurbation is so excessive on this site that Reader Mode is pretty much a requirement. A shame, because the actual content buried underneath is pretty great.

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?

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.
