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.

Using Hamburger Menus? Try Sausage Links · Bradley Taunt

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.

Work and life of Stanley Kubrick

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.

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.

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.

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.

CSS only scroll indicator

This is witchcraft. I’ve been deconstructing the CSS to figure out how this works and it’s really clever.

(Hint: try commenting out some of the CSS and see what happens.)

Sticky headers

I made a little tweak to The Session today. The navigation bar across the top is “sticky” now—it doesn’t scroll with the rest of the content.

I made sure that the stickiness only kicks in if the screen is both wide and tall enough to warrant it. Vertical media queries are your friend!

But it’s not enough to just put some position: fixed CSS inside a media query. There are some knock-on effects that I needed to mitigate.

I use the space bar to paginate through long pages. It drives me nuts when sites with sticky headers don’t accommodate this. I made use of Tim Murtaugh’s sticky pagination fixer. It makes sure that page-jumping with the keyboard (using the space bar or page down) still works. I remember when I linked to this script two years ago, thinking “I bet this will come in handy one day.” Past me was right!

The other “gotcha!” with having a sticky header is making sure that in-page anchors still work. Nicolas Gallagher covers the options for this in a post called Jump links and viewport positioning. Here’s the CSS I ended up using:

:target:before {
    content: '';
    display: block;
    height: 3em;
    margin: -3em 0 0;
}

I also needed to check any of my existing JavaScript to see if I was using scrollTo anywhere, and adjust the calculations to account for the newly-sticky header.

Anyway, just a few things to consider if you’re going to make a navigational element “sticky”:

  1. Use min-height in your media query,
  2. Take care of keyboard-initiated page scrolling,
  3. Adjust the positioning of in-page links.
