This strikes me as an eminently sensible idea by Emil: using the picture element to begin providing WebP alternatives to JPG.
Of course, picture-supporting browsers will have to adjust their decision-making algorithm to support this pattern.
Paul Ford’s potted history of web standards, delivered in his own inimitable style.
Reading through the standards, which are dry as can be, you might imagine that standardization is a polite, almost academic process, where wonks calmly debate topics like semicolon placement. This is not the case.
I’m an advocate for progressive enhancement. Tom Dale is not. But even though we may disagree on that, there’s a lot to like in his sensible, balanced answers to some sensationalist linkbaity questions.
It’s not that the pace of innovation on the Web is slower, it’s just solving a problem that is an order of magnitude more challenging than how to build and distribute trusted apps for a single platform. As we saw on the desktop, it may take a few years to catch up to all of the capabilities of a native, proprietary platform, but in terms of the impact it will have on humanity, forgive me for not losing sleep if we have to wait a few years for it to arrive.
I mentioned this a little while back, but it’s worth remembering just how many people are using Opera Mini …and how many more are about to join them.
Bring it on!
Angry, but true.
Don’t lock yourself into a comprehensive technology that may just die within the next few months and leave you stranded. With progressive enhancement you’ll never go wrong. Progressive enhancement means your code will always work, because you’ll always focus on providing a minimal experience first, and then adding features, functionality, and behavior on top of the content.
My name is Jeremy and I am a boring front-end developer.
I share the concerns expressed here about the “sizes” attribute that’s part of the new turbo-powered img element (or “the picture element and its associates”, if you prefer). Putting style or layout information into HTML smells bad.
This is a concern that Matt Wilcox has raised:
Change the design and those breakpoints are likely to be wrong. So you’ll need to change all of the client-side mark-up that references images.
I can give you a current use-case: right here on adactio.com, you can change the stylesheet …so I can’t embed breakpoints or sizes into my img elements because—quite rightly—there’s a separation between the structural HTML layer and the presentational CSS layer.
Following on from that post of Jason’s I linked to, Chris also emphasises that, for most use cases, you probably only need to use srcset (and maybe sizes), but not the picture element with explicit sources.
It’s really, really great that people are writing about this, because it can be quite a confusing topic to wrap your head around at first.
It’s very early days for ServiceWorker, but Jake is on hand with documentation and instructions on its use. To be honest, most of this is over my head and I suspect it won’t really “click” until I try using it for myself.
Where it gets really interesting is in the comments. Stuart asks “What about progressive enhancement?” And Jake points out that because a ServiceWorker won’t be installed on a first visit, you pretty much have to treat it as an enhancement. In fact, you’d have to go out of your way to make it a requirement:
You could, of course, throw up a splash screen and wait for the ServiceWorker to install, creating a ServiceWorker-dependant experience. I will hunt those people down.
Jason points out that the picture element might not be needed for most responsive image use cases; the srcset and sizes attributes will probably be enough—that’s what I’m doing for the photos on my site.
Bruce went to the Extensible Web Summit in Berlin and wrote up his notes.
Sounds like he shares my excitement, but also my nervousness.
There’s also this important point, that Alex would do well to remember before crying “Piffle and tosh!”:
We need to ensure that all devs who want to can participate by allowing ease of collaboration, courteous discourse.
Opera Mini is about to be installed as the default browser on a few more million phones.
Dan Donald gets to the heart of progressive enhancement:
Assumptions in themselves don’t have to be inherently bad but let’s recognise them for what they are. We know very little but that can hopefully enable us to be far more flexible and understanding in what we create.
One more reason why you should never sniff user-agent strings: Internet Explorer is going to lie some more. Can’t really blame them though—if developers didn’t insist on making spurious conclusions based on information in the user-agent string, then browsers wouldn’t have to lie.
Oh, and Internet Explorer is going to parse -webkit prefixed styles. Again, if developers hadn’t abused vendor prefixes, we wouldn’t be in this mess.
Personally, I’m all for more browsers. The more, the merrier.
I, for one, don’t welcome our applinks overlords.
So, you’re checking out your news feed on your Facebook app and you see a CNN post that you want to read. After reading the post on CNN, you decide you want to to read the source article on TMZ…
Some URLs are ugly. Some URLs aren’t. Let’s not sacrifice them.
A lovely post by Mark on the value of URLs.
Right now, this move to remove URLs from the interface of Chrome is just an experiment …but the fact that Google are even experimenting with it is very disturbing.
“Who? Me? No, I was never going to actually blow the web’s brains out—I just wanted to feel the heft of the weapon as I stroked it against the face of the web.”
Derek’s excellent advice on avoiding over-reliance on data attributes has this brilliant nugget of insight:
In the web front-end stack — HTML, CSS, JS, and ARIA — if you can solve a problem with a simpler solution lower in the stack, you should. It’s less fragile, more foolproof, and just works
I like this idea. It would be nice to see it catch on…
- Report a bug for any website or browser.
- Our team of volunteers diagnoses the bug.
- We send a fix to the site owner or browser.
A nice summation by Dan of when it makes sense to use a graphic design tool like Photoshop and when it makes sense to use a web browser.
John echoes some of my recent thinking about what qualifies as a web browser and, by extension, what qualifies as the web:
We shouldn’t think of “the web” as only what renders in web browsers. We should think of the web as anything transmitted using HTTP and HTTPS. Apps and websites are peers, not competitors. They’re all just clients to the same services.
That said, I think he is perhaps underestimating the power of URLs. Addressability—particularly over an extended time period—remains the powerful feature of the web.
A handy way of automating the creation of old-IE stylesheets using Grunt. This follows on from Jake’s work in using preprocessors and conditional comments to send a different stylesheet to IE8 and below—one that doesn’t contain media queries. It’s a clever way of creating mobile-first responsive sites that still provide large-screen styles to older versions of IE.
The importance of long-term thinking in web design. I love this description of the web:
a truly fluid, chaotic design medium serving millions of imperfect clients
Some good ideas on the idea of element-level media queries, a feature that developers are crying out for and browser makers are saying is too hard. This post has some thoughts on how to deal with the potential issues.
A lovely history lesson on CSS from John.
I think Chrome is doing the right thing by removing the 300 millisecond tap delay on sites that set width=device-width — it’s certainly better than only doing it on sites that set user-scalable=no, which felt like rewarding bad behaviour.
John shares his concerns about the increasing complexity involved in developing for the web.
Some excellent research for web developers: find out which unicode characters have the widest support—release useful for choosing icons.
I really like Scott’s approach to defining what “support” means in terms of browsers—it makes a lot sense to break things down to the component level.
The authors of the Extensible Web Manifesto explain the thinking behind their …uh… thinking.
Alex starts with a bit of a rant about the phrase “semantic HTML”, which should really just be “well-written HTML, but there then follows some excellent thoughts on the emergence of meaning and the process of standardising on vocabularies.
Good luck getting that script updated for the thousands of sites and applications, you say to yourself, where it’s laying dormant just waiting to send devices the wrong content based on a UA substring.
Henri gives an overview of the DRM-style encryption proposed for HTML. It’s a very balanced unbiased description, but if you have the slightest concern about security, sentences like this should give you the heebie-jeebies:
This is the worst idea for a W3C community group ever. Come to think of it, it’s the worst idea for an idea ever.
Brian writes up his experience working on the line-mode browser hack event at CERN.
Once you get past the cheesy intro music, there are some gems from Robert Cailliau in here.
I took a little time out of the hacking here at CERN to answer a few questions about the line-mode browser project.
This is what I’m working on today (where by “working on”, I mean “watching other far more talented people work on”).
Alas, that clever SVG fallback trick I linked to a couple of days ago has some unexpected performance side-effects.
WebKit nightlies now have support for
srcset. I’m pleased to see that it’s currently constrained to just handling the case of high-density displays; it doesn’t duplicate the media query functionality of
I’ve always maintained that the best solution to responsive images will be some combination of
picture: they each have their strengths and weaknesses. The “art direction” use case is better handled by
picture, but the “retina” use case is better handled by
A great call-to-arms from Tim, simply asking that we create websites that take advantage of the amazing universality of the web:
The web has the power to go anywhere—any network, any device, any browser. Why not take advantage of that?
Inevitably there is pushback in the comments from developers still in the “denial” stage of coming to terms with what the web is.
A call for developers to let standards bodies know what we want:
It is important that we as developers focus on the right things again. If you encounter a bug, you should not only fix it for your site; you should reach out to browser vendors and web standards people to fix this in a long-term solution. It might cost you a few minutes, but brings a lot of improvement to the whole developer community.
Well, this is interesting: it looks like Chrome might stop waiting 300ms for potential double-tap-to-zoom events if the site is using a meta viewport declaration that sets the width to device-width.

A terrific quiz about browser performance from Jake. I had the pleasure of watching him present this in a bar in Amsterdam—he was like a circus carny hoodwinking the assembled geeks.
I guarantee you won’t get all of this right, and that’s a good thing: you’ll learn something. If you do get them all right, either you are Jake or you are very, very sad.
Squee! I’m going to CERN on the 19th and 20th of September to take part in this hackday-like project to recreate the first line-browser.

Wow! The CSS Zen Garden is a decade old. Crazy! It’s a true piece of web history …and it’s back!
A handy plugin for Chrome that always you to inspect media query breakpoints and take screenshots at any of them.
A terrific piece by Remy—based on a talk he gave—on when he uses jQuery and, more importantly, when he doesn’t. His experiences and conclusions pretty much mirror my own, but of course Remy is far more thoughtful and smart than I.
Really good stuff.
Want to style those new HTML5 input types? I hope you like vendor prefixes.

A handy one-stop-shop for tips on improving front-end performance.
This issue of A List Apart is a great double-whammy. Lara Swanson has a ton of practical tips for front-end performance enhancements, and Brian dives deep into making your own icon fonts.
The “client hints” proposal looks really interesting: a way for user-agents to send data to the server without requiring the server to have a library of user-agent strings. But Scott has a few concerns about some of the details.
The slides from Anna’s terrific talk at the Responsive Day Out.
And this is why user-agent sniffing not a future-friendly technique. A new mobile browser comes along, and it has to spoof a fake UA string to all of these sites.
It’s a Red Queen arms race.
A very hand tip from Ben on using SVG background images with a PNG fallback for IE8 and below.
Everything you ever wanted to know about using SVG today.
A good explanation of the litany of woes that comes from Internet Explorer 8 being the highest that users of Windows XP can upgrade to. It’s a particularly woeful situation if you are a web developer attempting to provide parity. But there is hope on the horizon:
2013 will see the culmination of all these issues; support for IE 8 will drop of rapidly, users of XP will find an increasingly broken web, the cost of building software in XP organisations will increase.
A gorgeous collection of experiments that showcase just how much is possible in browsers today.
Bruce sits down for a chat with Hixie. This is a good insight into the past and present process behind HTML.

David takes a look at worldwide trends in web browsing, pointing out where mobile traffic exceeds desktop …and we’re not necessarily talking about smartphones here either.
It would be possible to travel from the Niger Delta on the west coast of Africa, to the horn of Africa on the east coast, without passing through a country where people surf more on desktop than a mobile phone.

Andrea looks at support for HTML5 input types in IE10 Mobile.
Useful advice from Tim on preparing your responsive site for IE10’s new “snap mode”. Don’t worry: it doesn’t involve adding any proprietary crap …quite the opposite, in fact.

Hey look; Anna’s in a CSSquirrel comic! And for good reason: Kyle is as impressed as I am with Anna’s research into browsers on gaming devices.
There’s also a call for more community device labs. I approve.
An excellent in-depth article from Anna on the many gaming devices out there that have both an internet connection and a web browser.
Luke collates some useful mobile browsing statistics once again. Most of it is quite US-centric, but this closing point is a whopper:
36 countries more than doubled their Opera Mini user bases in one year.
Bruce writes about a worrying trend in standards work:
Tossing a specification that you’ve written in-house, in secret and already implemented onto a table at W3C, saying “here, standardise this” as you saunter past isn’t a Get Out of Jail Free card for proprietary misdemeanours. And it isn’t standardisation.
Stuart on the importance of View Source.
A great behind-the-scenes look at the redesign (and redevelopment) of Twitter’s mobile subdomain silo. Man, I would love to see this progressively enhanced up to the current widescreen view for “desktop” browsers without the need for separate URLs for any class of device.
But I digress …this is good stuff.
Nicholas is inside my head! Get out of my head, Nicholas!
What makes the web beautiful is precisely that there are multiple browsers and, if you build things correctly, your sites and applications work in them all. They might not necessarily work exactly the same in them all, but they should still be able to work. There is absolutely nothing preventing you from using new features in your web applications, that’s what progressive enhancement is all about.
Here’s a brainbuster for ya: a single file that renders both as HTML and as a JPEG. As an HTML page, it even contains an img element with a src of …itself!
Compare the “view source” output with the generated source output to see it’s being interpreted.
Anna reports on her experience testing on a device we don’t often think about: the Nintendo DS …very popular with the young ‘uns.
A nice timeline visualisation of recent history.
Wilto does an excellent job of summarising the current state of responsive images, highlighting Florian Rivoal’s compromise proposal that combines the best of the picture element with the best of srcset.
Well, I guess this is one way of encouraging people to upgrade their browser.
A nice round-up of the issues around responsive images and their potential solutions.
This is an excellent idea from Jake: use a preprocessor to automatically spit out a stylesheet for older versions of IE that includes desktop styles (garnered from the declarations within media queries).
If you’re a dab hand with Ruby and you’d like to see this in SASS, you can help.

Have you thought “There must be a good reason for the blink element.” Well, read on.
Here’s the video of the mobile browser panel I moderated at Mobilism in Amsterdam. These guys were really good sports to put up with my wisecracking shots for cheap laughs at their expense.
This seems like a sensible way for browsers to approach implementing vendor-prefixed CSS properties.
This is the absolutely worst way to think about browser support: because the design doesn’t render “pixel perfect” (whatever that means) in a browser, that browser is blocked from accessing content. This is completely unnecessary and shows a fundamental lack of understanding of the web’s greatest feature: progressive enhancement.
