Tim explains why that neat trick of making a really big JPEG with quality set to 0% is no longer necessary, and how the savings you make in bandwidth with that technique are nullified by the expense of the memory footprint needed.

Here’s a really smart approach to creating container queries today—it uses
ResizeObserver to ensure that listening for size changes is nice and performant.
There’s a demo site you can play around with to see it in action.
While the strategy I outline in this post is production-ready, I see us as being still very much in the early stages of this space. As the web development community starts shifting its component design from viewport or device-oriented to container-oriented, I’m excited to see what possibilities and best practices emerge.

A well-written (and beautifully designed) article on the nature of the web, and what that means for those of us who build upon it. Matthias builds on the idea of material honestly and concludes that designing through prototypes—rather than making pictures of websites—results in a truer product.
A prototyping mindset means cultivating transparency and showing your work early to your team, to users – and to clients as well, which can spark excited conversations. A prototyping mindset also means valuing learning over fast results. And it means involving everyone from the beginning and closely working together as a team to dissolve the separation of linear workflows.

From Scott McCloud to responsive design, Dave is pondering our assumptions about screen real estate:
As the amount of information increases, removing details reduces information density and thereby increasing comprehension.
It reminds me of Edward Tufte’s data-ink ratio.

An extract from Richard’s excellent book, this is a deep dive into styling tables for the web (featuring some CSS I had never even heard of).
Tables can be beautiful but they are not works of art. Instead of painting and decorating them, design tables for your reader.
(It also contains a splendid use of the term “crawl bar.”)

What an excellent example of a responsive calendar!

The BBC has been experimenting with some alternative layouts for some articles on mobile devices. Read on for the details, but especially for the philosophical musings towards the end—this is gold dust:
Even the subtext of Google’s marketing push around Progressive Web Apps is that mobile websites must aspire to be more like native apps. While I’m as excited about getting access to previously native-only features such as offline support and push notifications as the next web dev, I’m not sure that the mobile web should only try to imitate the kind of user interfaces that we see on native.
Do mobile websites really dream of being native apps, any more than they dreamt of being magazines?

Every single browser maker has the same stance when it comes to features—they want to hear from developers at the coalface.
“Tell us what you want! We’re listening. We want to know which features to prioritise based on real-world feedback from developers like you.”
“How about container quer—”
I don’t think it’s an exaggeration to say that literally every web developer I know would love to have container queries. If you’ve worked on any responsive project of any size, you’re bound to have bumped up against the problem of only being able to respond to viewport size, rather than the size of the containing element. Without container queries, our design systems can never be truly modular.
But there’s a divide growing between what our responsive designs need to do, and the tools CSS gives us to meet those needs. We’re making design decisions at smaller and smaller levels, but our code asks us to bind those decisions to a larger, often-irrelevant abstraction of a “page.”
But the message from browser makers has consistently been “it’s simply too hard.”
Now, as I understand it, Houdini is the CSS arm of the extensible web. Just as web components will allow us to create powerful new HTML without lobbying browser makers, Houdini will allow us to create powerful new CSS features without going cap-in-hand to standards bodies.
During the talks, you could send questions over Twitter that the speaker could be quizzed on afterwards. As Philip was talking, I began to tap out a question: “Could this be used to polyfill container queries?” My thumb was hovering over the tweet button at the very moment that Philip said in his talk, “This could be used to polyfill container queries.”
For that happen, browsers need to implement the layout API for Houdini. But I’m betting that browser makers will be far more receptive to calls to implement the layout API than calls for container queries directly.
Once we have that, there are two possible outcomes:
- We try to polyfill container queries and find out that the browser makers were right—it’s simply too hard. This certainty is itself a useful outcome.
- We successfully polyfill container queries, and then instead of asking browser makers to figure out implementation, we can hand it to them for standardisation.
But, as Eric Portis points out in his talk on container queries, Houdini is still a ways off (by the way, browser makers, that’s two different conference talks I’ve mentioned about container queries, just in case you were keeping track of how much developers want this).
However it happens, I’d just love to see some movement on container queries. I’m not alone.
I know container queries would revolutionize my design practice, and better prepare responsive design for mobile, desktop, tablet—and whatever’s coming next.

Progressing the web
Frances has written up some of the history behind her minting of the term “progressive web app”. She points out that accuracy is secondary to marketing:
I keep seeing folks (developers) getting all smart-ass saying they should have been PW “Sites” not “Apps” but I just want to put on the record that it doesn’t matter. The name isn’t for you and worrying about it is distraction from just building things that work better for everyone. The name is for your boss, for your investor, for your marketeer.
Personally, I think “progressive web app” is a pretty good phrase—two out of three words in it are spot on. I really like the word “progressive”, with its echoes of progressive enhancement. I really, really like the word “web”. But, yeah, I’m one of those smart-asses who points out that the “app” part isn’t great.
That’s not just me being a pedant (or, it’s not only me being a pedant). I’ve seen people who were genuinely put off investigating the technologies behind progressive web apps because of the naming.
The name is one of the reasons I didn’t look into PWAs 6 months ago. Can we change the name itself? 😎— Julian Gaviria (@juliangav) March 24, 2017
Here’s an article with the spot-on title Progressive Web Apps — The Next Step In Responsive Web Design:
Late last week, Smashing Magazine, one of the largest and most influential online publications for web design, posted on Facebook that their website was “now running as a Progressive Web App.”
Honestly, I didn’t think much of it. Progressive Web Apps are for the hardcore web application developers creating the next online cloud-based Photoshop (complicated stuff), right? I scrolled on and went about my day.
And here’s someone feeling the cognitive dissonance of turning a website into a progressive web app, even though that’s exactly the right thing to do:
My personal website is a collection of static HTML files and is also a progressive web app. Transforming it into a progressive web app felt a bit weird in the beginning because it’s not an actual application but I wanted to be one of the cool kids, and PWAs still offer a lot of additional improvements.
Still, it could well be that these are the exceptions and that most people are not being discouraged by the “app” phrasing. I certainly hope that there aren’t more people out there thinking “well, progressive web apps aren’t for me because I’m building a content site.”
In short, the name might not be perfect but it’s pretty damn good.
What I find more troubling is the grouping of unrelated technologies under the “progressive web app” banner. If Google devrel events were anything to go by, you’d be forgiven for thinking that progressive web apps have something to do with AMP or Polymer (they don’t). One of the great things about progressive web apps is that they are agnostic to tech stacks. Still, I totally get why Googlers would want to use the opportunity to point to their other projects.
Far more troubling is the entanglement of the term “progressive web app” with the architectural choice of “single page app”. I’m not the only one who’s worried about this.
I’ve seen too many devs assume PWA is a subset of SPA. We need to improve our messaging— Jake Archibald (@jaffathecake) June 4, 2016
Here’s the most egregious example: an article on Hacker Noon called Before You Build a PWA You Need a SPA.
No! Not true! Literally any website can be a progressive web app:
Alas, I think that many of the initial poster-children for progressive web apps gave the impression that you had to make a completely separate app/site at a different URL. It was like a return to the bad old days of
m. sites for mobile. The Washington Post’s progressive web app (currently offline) went so far as to turn away traffic from the “wrong” browsers. This is despite the fact that the very first item in the list of criteria for a progressive web app is:
Responsive: to fit any form factor
Now, I absolutely understand that the immediate priority is to demonstrate that a progressive web app can compete with a native mobile app in terms of features (and trounce it in terms of installation friction). But I’m worried that in our rush to match what native apps can do, we may end up ditching the very features that make the web a universally-accessible medium. Killing URLs simply because native apps don’t have URLs is a classic example of throwing the baby out with the bath water:
Up until now I’ve been a big fan of Progressive Web Apps. I understood them to be combining the best of the web (responsiveness, linkability) with the best of native (installable, connectivity independent). Now I see that balance shifting towards the native end of the scale at the expense of the web’s best features. I’d love to see that balance restored with a little less emphasis on the “Apps” and a little more emphasis on the “Web.” Now that would be progressive.
If the goal of the web is just to compete with native, then we’ve set the bar way too low.
So if you’ve been wary of investing the technologies behind progressive web apps because you’re “just” building a website, please try to see past the name. As Frances says:
It’s marketing, just like HTML5 had very little to do with actual HTML. PWAs are just a bunch of technologies with a zingy-new brandname.
Literally any website can—and should—be a progressive web app. Don’t let anyone tell you otherwise.
I was at an event last year where I heard Chris Heilmann say that you shouldn’t make your blog into a progressive web app. I couldn’t believe what I was hearing. He repeats that message in this video chat:
When somebody, for example, turns their blog into a PWA, I don’t see the point. I don’t want to have that icon on my homepage. This doesn’t make any sense to me.
Excuse me!? Just because you don’t want to have someone’s icon on your home screen, that person shouldn’t be using state-of-the-art technologies!? Excuse my French, but Fuck. That. Shit!
Our imaginations have become so limited by what native mobile apps currently do that we can’t see past merely imitating the status quo like a sad cargo cult.
I don’t want the web to equal native; I want the web to surpass it. I, for one, would prefer a reality where my home screen isn’t filled with the icons of startups and companies that have fulfilled the criteria of the gatekeepers. But a home screen filled with the faces of people who didn’t have to ask anyone’s permission to publish? That’s what I want!
Like Frances says:
Remember, this is for everyone.

Mike examines the real power of CSS custom properties compared to Sass variables—they can change at runtime.
I’m convinced that in almost all cases, responsive design logic should now be contained in variables. There is a strong argument too, that when changing any value, whether in a media query or an element scope, it belongs in a variable. If it changes, it is by definition a variable and this logic should be separated from design.

Your website’s only as strong as the weakest device you’ve tested it on.

It’s no substitute for testing with real devices, but the “device wall” view in this Chrome plug-in is a nifty way of getting an overview of a site’s responsiveness at a glance.

Chris rounds up the discussion that’s been happening around container queries, for and against.
Personally, I’d like to see about 100 different use cases fleshed out. If it turns out some of them can be done sans container queries, awesome, but it still seems highly likely to me that having container queries available to us would be mighty handy.

Paul’s being contrary again.
Seriously though, this is a good well-reasoned post about why container queries might not be the the all-healing solution for our responsive design problems. Thing is, I don’t think container queries are trying to be an all-encompassing solution, but rather a very useful solution for one particular class of problem.
So I don’t really see container queries competing with, say, grid layout (any more than grid layout is competing with flexbox), but rather one more tool that would be really useful to have in our arsenal.
