This is such a great clear explanation from Lynn on how to add some tasteful parallax depth to scrolling pages.
This is a useful technique that future me is almost certainly going to need at some point.
Cassie’s enthusiasm for fun and interesting SVG animation shines through in her writing!
Progressive disclosure interface patterns categorised and evaluated:
- mouseover popups (just say no!),
- new pages,
- 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.
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:
It looks (a more complex version of) fragmention might be coming to Chrome.
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.
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.

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: fixedwould 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.
It’s our job as designers to bring clarity back to the digital canvas by crafting reading experiences that put readers first.
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.
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:
- Respect the Physics
- Remember that We Call Them “Readers”
- 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?
One more reason not to use sticky headers on mobile.
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.
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.
Three very easy to implement additions to scrollable areas of your web pages:
role="region", and an
