This is a wonderful interactive explanation of the way CSS hierarchy works—beautiful!

I’ve been thinking about some of the default behaviours that are built into web browsers.
First off, there’s the decision that a browser makes if you enter a web address without a protocol. Let’s say you type in
example.com without specifying whether you’re looking for
Browsers default to HTTP rather than HTTPS. Given that HTTP is older than HTTPS that makes sense. But given that there’s been such a push for TLS on the web, and the huge increase in sites served over HTTPS, I wonder if it’s time to reconsider that default?
Most websites that are served over HTTPS have an automatic redirect from HTTP to HTTPS (enforced with HSTS). There’s an ever so slight performance hit from that, at least for the very first visit. If, when no protocol is specified, browsers were to attempt to reach the HTTPS port first, we’d get a little bit of a speed improvement.
But would that break any existing behaviour? I don’t know. I guess there would be a bit of a performance hit in the other direction. That is, the browser would try HTTPS first, and when that doesn’t exist, go for HTTP. Sites served only over HTTP would suffer that little bit of lag.
Whatever the default behaviour, some sites are going to pay that performance penalty. Right now it’s being paid by sites that are served over HTTPS.
Here’s another browser default that Rob mentioned recently: the
I thought I might be able to get away with omitting
meta name="viewport". Apparently not! Maybe someday.
This all goes back to the default behaviour of Mobile Safari when the iPhone was first released. Most sites wouldn’t display correctly if one pixel were treated as one pixel. That’s because most sites were built with the assumption that they would be viewed on monitors rather than phones. Only weirdos like me were building sites without that assumption.
So the default behaviour in Mobile Safari is assume a page width of 1024 pixels, and then shrink that down to fit on the screen …unless the developer over-rides that behaviour with a
meta tag. That default behaviour was adopted by other mobile browsers. I think it’s a universal default.
But the web has changed since the iPhone was released in 2007. Responsive design has swept the web. What would happen if mobile browsers were to assume
meta element always felt like a (proprietary) band-aid rather than a long-term solution—for one thing, it’s the kind of presentational information that belongs in CSS rather than HTML. It would be nice if we could bid it farewell.

Supporting Internet Explorer 11 doesn’t mean you need to give it the same experience as a modern browser:
Making sure (some of) your code works in older browsers, does not mean all functionality has to work everywhere. But, mind you, ninety percent of web development means putting text and images in boxes.
And to be honest, there is no reason to not enable this everywhere. Same for form submissions. Make it boring. Make it solid. And sprinkle delight on it.
Surveillance giants: How the business model of Google and Facebook threatens human rights | Amnesty International
Amnesty International have released a PDF report on the out-of-control surveillance perpetrated by Google and Facebook:
Google and Facebook’s platforms come at a systemic cost. The companies’ surveillance-based business model forces people to make a Faustian bargain, whereby they are only able to enjoy their human rights online by submitting to a system predicated on human rights abuse. Firstly, an assault on the right to privacy on an unprecedented scale, and then a series of knock-on effects that pose a serious risk to a range of other rights, from freedom of expression and opinion, to freedom of thought and the right to non-discrimination.
This page on the Amnesty International website has six tracking scripts. Also, consent to accept tracking cookies is assumed (check dev tools). It looks like you can reject marketing cookies, but I tried that without any success.
The stone PDF has been thrown from a very badly-performing glass house.

When it comes to frameworks and UI libraries, there are some interesting numbers. Given the volume of chatter in the dev world, you’d be forgiven for thinking that React is used on the majority of websites today. The real number? 4.6% of websites. That’s less than the number of websites using CSS custom properties.
This is reminding me of what I wrote about dev perception.

With a Progressive Enhancement mindset, support actually means support. We’re not trying to create an identical experience: we’re creating a viable experience instead.
Also with Progressive Enhancement, it’s incredibly likely that your IE11 user, or your user on a low-powered device, or even your user on a poor connection won’t notice that they’re experiencing a “minor” experience because it’ll just work for them. This is the magic, right there. Everyone’s a winner.

The transcript of a fantastic talk by Stuart. The latter half is a demo of Portals, but in the early part of the talk, he absolutely nails the rise in popularity of complex front-end frameworks:
I think the reason people started inventing client-side frameworks is this: that you lose control when you load another page. You click on a link, you say to the browser: navigate to here. And that’s it; it’s now out of your hands and in the browser’s hands. And then the browser gives you back control when the new page loads.

PWAs just work better than your typical mobile site. Period.
But bear in mind:
Maybe simply because the “A” in PWA stands for “app,” too much discussion around PWAs focuses on comparing and contrasting to native mobile applications. We believe this comparison (and the accompanying discussion) is misguided.

The web embodies principles of openness and portability and access that best align with the needs, and frankly the purpose, of the cultural heritage sector.
Aaron’s talk from the 2019 Museums and the Web conference.
In 2019 the web is not “sexy” anymore and compared to native platforms it can sometimes seems lacking, but I think that speaks as much to people’s desire for something “new” as it does to any apples to apples comparison. On measure – and that’s the important part: on measure – the web affords a better and more sustainable framework for the cultural heritage to work in than any of the shifting agendas of the various platform vendors.

This is very handy! Export your data from Ev’s blog and then import it into a static site generator of your choice.
You may have noticed the recent movement of people looking to get off Medium. Most of us are motivated by a desire to own our content, have data portability and get more control over how/where our content is displayed and monetized. Most importantly many of us consider our blog/site to be a core part of our online identity and while Medium offers a fantastic writing experience it sacrifices other important values. Luckily there’s a modern approach to running your blog which aligns with these ideals, its called the JAMstack and its all around us.

Andrew looks at AMP from a technical, UX, and commercial perspective. It looks pretty bad in all three areas. And the common thread is the coercion being applied to publishers.
But casting the web aside and pushing a new proprietary content format (which is optional, but see coercion) seems like an extraordinarily heavy handed way to address it. It’s like saying I see you have a graze on your knee so let’s chop off and replace your whole leg. Instead, we could use the carrot of a premium search result position (as AMP has done) and make it only possible to be there if your site is fast.
He’s absolutely right about how it sounds when the AMP team proudly talk about how many publishers are adopting their framework, as if the framework were actually standing on its own merits instead of being used to blackmail publishers:
It is utterly bizarre to me, akin to a street robber that has convinced himself that people just randomly like giving him their money and has managed to forget the fact that he’s holding a gun to their head.

Never mind their recent data breach—the reason to avoid Quora is that it’s a data roach motel.
All of Quora’s efforts to lock up its community’s contributions make it incredibly difficult to preserve when that they go away, which they someday will. If you choose to contribute to Quora, they’re actively fighting to limit future access to your own work.
