2020 is only three weeks old, but there has been a lot of browser news that decreases rendering engine diversity. It’s time for some good news on that front: a new rendering engine, Flow. Below I conduct an interview with Piers Wombwell, Flow’s lead developer. This year alone, on the negative side Mozilla announced it’s laying off 70 people, most of whom appear to come from the browser side of thi

I think that CSS would be greatly helped if we solemnly state that “CSS4 is here!” In this post I’ll try to convince you of my viewpoint. I am proposing that we web developers, supported by the W3C CSS WG, start saying “CSS4 is here!” and excitedly chatter about how it will hit the market any moment now and transform the practice of CSS. Of course “CSS4” has no technical meaning whatsoever. All cu

What do a recent A List Apart article, the ad blocker discussion of a few months back, and my browser testing plans have in common? Free content entitlement, that’s what. I’m seriously questioning the idea that all content on the web ought to be free. I think it’s an essentially accidental initial state of the web that quietly became the default. By now, consumers (also of web development blogs) f

After my recent post about updating Chromium WebViews I was contacted by Scientia Mobile, the company behind the WURFL database, and was offered actual real-life stats! The situation is less dire than I assumed. About 90% of the users do in fact use the latest Chromium WebView. This number is based on several hundred million hits in December 2015, primarily from North America and Europe. The full

I feel it’s time to revisit the web vs. native debate, and concede defeat — or, at least, concede that the web cannot, and should not, compete with native when it comes to complex, app-like structures. I feel we’ve gone too far in emulating native apps. Conceding defeat will force us to rethink the web’s purpose and unique strengths — and that’s long overdue. I feel that our desire to take on nati

Yesterday, in reaction to pointer events becoming a W3C recommendation, Tim Kadlec published an important piece about Apple’s huge influence on the mobile web. I agree with him to the extent of writing this extended Me-Too entry. It is increasingly becoming necessary to do something about Apple, its absolute refusal to talk to anyone, and its dickish way of bending the mobile web to its desires. P

In the last six months or so I talked to several prospective clients that had a problem finding front-end consultants in order to help their dev teams get a grip on their Angular projects. Although there are front-enders that are enthusiastic about Angular, I have the feeling that their number is surprisingly low for a major framework. I expected Angular to gain more traction than it has. Angular

For at least a year now I’ve held to the theory that the huge uptake in Chrome we’re seeing on the mobile web is mostly due to Samsung using its own version (based on Chromium 28) in its high-end smart devices from the Galaxy S4 on. Yesterday Krijn started tweeting about mobile stats he had, and it turned out he was willing to share. He gave me data on about 100K mobile and tablet hits in Q2 on a

There are two really curious cases here: the huge amount of use for device-width, and the huge difference between device-pixel-ratio and resolution. Resolutions Let’s start with that last case. About one quarter of web developers wants to know what resolution they’re on — most likely in order to use some sort of responsive images solution. The problem here is that device-pixel-ratio works only in

One common problem on iOS is that, when you use a meta viewport tag with width=device-width, the page doesn’t react to an orientation change. On the iPhone the page becomes 320px wide and on the iPad 768px, regardless of whether you’re in portrait or in landscape mode. Sometimes this is annoying. Today I found a solution: use initial-scale=1 instead of width=device-width. Although I’m not the firs

So Google created Blink, the new rendering engine for Chrome and Opera. What exactly is going on, and what will the consequences be? Here are some notable sources on Blink that I used for this overview: Blink homepage and developer FAQ. Chromium feature dashboard, where you can see which new features are going to be added. Can use an interface upgrade; right now it’s hard to read. Alex Russell on

In the past month I’ve researched CSS gradients, and I can finally present my findings. As usual, there was no source that gives clear, concise, accurate information about the three syntaxes and the four rendering engines, so I decided to write it myself. Here is the inevitable compatibility table. Below I excerpt part of my introduction to gradients. The problem with gradients is that they are a

Yesterday I found that proper hyphenation of text is now supported by Firefox, IE10, and Safari. So I added it to my main style sheet and it should work in these browsers across my site. I also advise you to add it to your sites straight away. The code: -webkit-hyphens: auto; -moz-hyphens: auto; -ms-hyphens: auto; -o-hyphens: auto; hyphens: auto; So far it’s prefixed, and Opera and Chrome don’t su

I held a JavaScript library poll in the last three weeks, and it’s time to publish the results. At least 3,350 people responded. With nearly 155,000 responses in total, and nearly 1,700 for the least-answered question, I believe this poll is fairly representative of my readers and the readers of my readers, and therefore gives genuinely useful information about current JavaScript library use.

It occurs to me that my recent post about devicePixelRatio was a bit cryptic and short. So I will givde some extra examples in this post. Also, I did some additional research that takes screen.width into account. Remember the definition: devicePixelRatio is the ratio between physical pixels and device-independent pixels (dips) on the device. devicePixelRatio = physical pixels / dips Here is the te

I did some research around the window.devicePixelRatio property that all WebKit browsers, as well as Opera, support, and for once the news is good. This property’s definition makes sense, and it is implemented almost universally. Definition Let’s start with a definition: window.devicePixelRatio is the ratio between physical pixels and device-independent pixels (dips) on the device. window.devicePi

OK, so now we have the rumour that Facebook is going to buy Opera. That would be unexpected. And interesting. In this entry I’m going to pretend the news is true, even though that’s not certain yet, because it is a good starting point for some serious strategic thinking. What is Facebook buying? So. What exactly is Facebook buying here? The obvious answer is that it’s buying the largest (or second
