Meet Utopia: Designing And Building With Fluid Type And Space Scales — Smashing Magazine

An excellent explainer from Trys and James of their supersmart Utopia approach:

Utopia encourages the curation of a system small enough to be held in short-term memory, rather than one so sprawling it must be constantly referred to.

Prototyping on the Clearleft podcast

The latest episode of the Clearleft podcast is live and it’s all about prototyping.

There’s a bit of a narrative thread in there about airplanes, kicked off by a great story Benjamin tells about testing a physical prototype …of the inside of a transatlantic airliner. Lorenzo recounts his story of mocking up a fake CMS with readily-available tools. And Trys tells of a progressive web app he whipped up for our friends at Suffolk Libraries. There’s even a bit about Hack Farm in there too.

But just to make sure it isn’t too much of a Clearleft love-in, I also interviewed an outside expert: Adekunle Oduye. It was very kind of him to give up his time, especially considering he had just moved house …in a pandemic!

There are some great words of wisdom, immortalised in the transcript:

Prototypical code isn’t production code. It’s quick and it’s often a little bit dirty and it’s not really fit for purpose in that final deliverable. But it’s also there to be inspiring and to gather a team and show that something is possible.


If you’re building something and you’re not really sure if it’s a right solution, use the word prototype versus design, because I feel like when people say design, that’s like the end result.


I always think of a prototype as a prop. It’s something to look at, something to prod. And ideally you’re trying to work out what works and what doesn’t.

— Benjamin

The whole episode is just over 21 minutes long. Have a listen and enjoy the stories.

If you like what you hear, please spread the word. Tell your Slack colleagues, your Twitter friends, your LinkedIn acquaintances. And if you’re not already subscribed, you can remedy that on Apple Podcasts, Google Podcasts, Spotify, Overcast and anywhere that accepts RSS.

Continuous Typography / MK

Sounds like some convergent thinking with the ideas behind Utopia.

I think that the idea that that any typographic attribute (including variable font parameters) can be a function (linear, exponential, stepped, Bezier, random, or otherwise) of any given input variable (user preference, screen dimensions, connection speed, time of day, display language, or whatever else) is an incredibly powerful one, and worth exploring as an aesthetic as well as a technical proposition.

Here’s a demo you can play with.

Standards processing

I’ve been like a dog with a bone the way I’ve been pushing for a declarative option for the Web Share API in the shape of button type=“share”. It’s been an interesting window into the world of web standards.

The story so far…

That’s the situation currently. The general consensus seems to be that it’s probably too soon to be talking about implementation at this stage—the Web Share API itself is still pretty new—but gathering data to inform future work is good.

In planning for the next TPAC meeting (the big web standards gathering), Marcos summarised the situation like this:

Not blocking: but a proposal was made by @adactio to come up with a declarative solution, but at least two implementers have said that now is not the appropriate time to add such a thing to the spec (we need more implementation experience + and also to see how devs use the API) - but it would be great to see a proposal incubated at the WICG.

Now this where things can get a little confusing because it used to be that if you wanted to incubate a proposal, you’d have to do on Discourse, which is a steaming pile of crap that requires JavaScript in order to put text on a screen. But Šime pointed out that proposals can now be submitted on Github.

So that’s where I’ve submitted my proposal, linking through to the explainer document.

Like I said, I’m not expecting anything to happen anytime soon, but it would be really good to gather as much data as possible around existing usage of the Web Share API. If you’re using it, or you know anyone who’s using it, please, please, please take a moment to provide a quick description. And if you could help spread the word to get that issue in front of as many devs as possible, I’d be very grateful.

(Many thanks to everyone who’s already contributed to that issue—much appreciated!)

The reason for a share button type

If you’re at all interested in what I wrote about a declarative Web Share API—and its sequel, a polyfill for button type=”share”—then you might be interested in an explainer document I’ve put together.

It’s a useful exercise for me to enumerate the reasoning for button type=“share” in one place. If you have any feedback, feel free to fork it or create an issue.

The document is based on my initial blog posts and the discussion that followed in this issue on the repo for the Web Share API. In that thread I got some pushback from Marcos. There are three points he makes. I think that two of them lack merit, but the third one is actually spot on.

Here’s the first bit of pushback:

Apart from placing a button in the content, I’m not sure what the proposal offers over what (at least one) browser already provides? For instance, Safari UI already provides a share button by default on every page

But that is addressed in the explainer document for the Web Share API itself:

The browser UI may not always be available, e.g., when a web app has been installed as a standalone/fullscreen app.

That’s exactly what I wanted to address. Browser UI is not always available and as progressive web apps become more popular, authors will need to provide a way for users to share the current URL—something that previously was handled by browsers.

That use-case of sharing the current page leads nicely into the second bit of pushback:

The API is specialized… using it to share the same page is kinda pointless.

But again, the explainer document for the Web Share API directly contradicts this:

Sharing the page’s own URL (a very common case)…

Rather than being a difference of opinion, this is something that could be resolved with data. I’d really like to find out how people are currently using the Web Share API. How much of the current usage falls into the category of “share the current page”? I don’t know the best way to gather this data though. If you have any ideas, let me know. I’ve started an issue where you can share how you’re using the Web Share API. Or if you’re not using the Web Share API, but you know someone who is, please let them know.

Okay, so those first two bits of pushback directly contradict what’s in the explainer document for the Web Share API. The third bit of pushback is more philosophical and, I think, more interesting.

The Web Share API explainer document does a good job of explaining why a declarative solution is desirable:

The link can be placed declaratively on the page, with no need for a JavaScript click event handler.

That’s also my justification for having a declarative alternative: it would be easier for more people to use. I said:

At a fundamental level, declarative technologies have a lower barrier to entry than imperative technologies.

But Marcos wrote:

That’s demonstrably false and a common misconception: See OWL, XForms, SVG, or any XML+namespace spec. Even HTML is poorly understood, but it just happens to have extremely robust error recovery (giving the illusion of it being easy). However, that’s not a function of it being “declarative”.

He’s absolutely right.

It’s not so much that I want a declarative option—I want an option that has robust error recovery. After all, XML is a declarative language but its error handling is as strict as an imperative language like JavaScript: make one syntactical error and nothing works. XML has a brittle error-handling model by design. HTML and CSS have extremely robust error recovery by design. It’s that error-handling model that gives HTML and CSS their robustness.

I’ve been using the word “declarative” when I actually meant “robust in handling errors”.

I guess that when I’ve been talking about “a declarative solution”, I’ve been thinking in terms of the three languages parsed by browsers: HTML, CSS, and JavaScript. Two of those languages are declarative, and those two also happen to have much more forgiving error-handling than the third language. That’s the important part—the error handling—not the fact that they’re declarative.

I’ve been using “declarative” as a shorthand for “either HTML or CSS”, but really I should try to be more precise in my language. The word “declarative” covers a wide range of possible languages, and not all of them lower the barrier to entry. A declarative language with a brittle error-handling model is as daunting as an imperative language.

I should try to use a more descriptive word than “declarative” when I’m describing HTML or CSS. Resilient? Robust?

With that in mind, button type=“share” is worth pursuing. Yes, it’s a declarative option for using the Web Share API, but more important, it’s a robust option for using the Web Share API.

I invite you to read the explainer document for a share button type and I welcome your feedback …especially if you’re currently using the Web Share API!

Downloading from Google Fonts

If you’re using web fonts, there are good performance (and privacy) reasons for hosting your own font files. And fortunately, Google Fonts gives you that option. There’s a “Download family” button on every specimen page.

But if you go ahead and download a font family from Google Fonts, you’ll notice something a bit odd. The .zip file only contains .ttf files. You can serve those on the web, but it’s far from the best choice. Woff2 is far leaner in file size.

This means you need to manually convert the downloaded .ttf files into .woff or .woff2 files using something like Font Squirrel’s generator. That’s fine, but I’m curious as to why this step is necessary. Why doesn’t Google Fonts provide .woff or .woff2 files in the downloaded folder? After all, if you choose to use Google Fonts as a third-party hosting service for your fonts, it most definitely serves up the appropriate file formats.

I thought maybe it was something to do with the licensing. Maybe some licenses only allow for unmodified truetype files to be distributed? But I’ve looked at fonts with different licenses—some have Apache 2 licensing, some have Open Font licensing—and they’re all quite permissive and definitely allow for modification.

Maybe the thinking is that, if you’re hosting your own font files, then you know what you’re doing and you should be able to do your own file conversion and subsetting. But I’ve come across more than one website in the wild serving up .ttf files. And who can blame them? They want to host their own font files. They downloaded those files from Google Fonts. Why shouldn’t they assume that they’re good to go?

It’s all a bit strange. If anyone knows why Google Fonts only provides .ttf files for download, please let me know. In a pinch, I will also accept rampant speculation.

Trys also pointed out some weird default behaviour if you do let Google Fonts do the hosting for you. Specifically if it’s a variable font. Let’s say it’s a font with weight as a variable axis. You specify in advance which weights you’ll be using, and then it generates separate font files to serve for each different weight.

Doesn’t that defeat the whole point of using a variable font? I mean, I can see how it could result in smaller file sizes if you’re just using one or two weights, but isn’t half the fun of having a weight axis that you can go crazy with as many weights as you want and it’s all still one font file?

Like I said, it’s all very strange.


If you’ve been following my recent blog posts about a declarative option for the Web Share API, you might be interested in this explainer document I’ve put together. It outlines the use case for button type="share".

Clamp | Utopia

Trys has been investigating how to incorporate CSS clamp() into the brilliant Utopia project. I won’t pretend to understand all the maths here—this is a very deep dive!

He’s also created a CSS generator Mark 2 if you want to use clamp() in your fluid type.

What is happening to our digital archives?

Employing the principle of least power for better digital preservation:

New frameworks and technologies spring up to try and cope with the speed of change. More and more ways to build and release things faster and cheaper becomes the norm. And, the more this happens, the more we deviate from standards: good ol’ HTML and CSS.

A polyfill for button type=”share”

After writing about a declarative Web Share API here yesterday I thought I’d better share the idea (see what I did there?).

I opened an issue on the Github repo for the spec.

(I hope that’s the right place for this proposal. I know that in the past ideas were kicked around on the Discourse site for Web platform Incubator Community Group but I can’t stand Discourse. It literally requires JavaScript to render anything to the screen even though the entire content is text. If it turns out that that is the place I should’ve posted, I guess I’ll hold my nose and do it using the most over-engineered reinvention of the browser I’ve ever seen. But I believe that the plan is for WICG to migrate proposals to Github anyway.)

I also realised that, as the JavaScript Web Share API already exists, I can use it to polyfill my suggestion for:

<button type="share">

The polyfill also demonstrates how feature detection could work. Here’s the code.

This polyfill takes an Inception approach to feature detection. There are three nested levels:

  1. This browser supports button type="share". Great! Don’t do anything. Otherwise proceed to level two.
  2. This browser supports the JavaScript Web Share API. Use that API to share the current page URL and title. Otherwise proceed to level three.
  3. Use a mailto: link to prefill an email with the page title as the subject and the URL in the body. Ya basic!

The idea is that, as long as you include the 20 lines of polyfill code, you could start using button type="share" in your pages today.

I’ve made a test page on Codepen. I’m just using plain text in the button but you could use a nice image or SVG or combination. You can use the Codepen test page to observe two of the three possible behaviours browsers could exhibit:

  1. A browser supports button type="share". Currently that’s none because I literally made this shit up yesterday.
  2. A browser supports the JavaScript Web Share API. This is Safari on Mac, Edge on Windows, Safari on iOS, and Chrome, Samsung Internet, and Firefox on Android.
  3. A browser supports neither button type="share" nor the existing JavaScript Web Share API. This is Firefox and Chrome on desktop (and Edge if you’re on a Mac).

See the Pen Polyfill for button type=”share" by Jeremy Keith (@adactio) on CodePen.

The polyfill doesn’t support Internet Explorer 11 or lower because it uses the DOM closest() method. Feel free to fork and rewrite if you need to support old IE.

A declarative Web Share API

I’ve written about the Web Share API before. It’s a handy little bit of JavaScript that—if supported—brings up a system-level way of sharing a page. Seeing as it probably won’t be long before we won’t be able to see full URLs in browsers anymore, it’s going to fall on us as site owners to provide this kind of fundamental access.

Right now the Web Share API exists entirely in JavaScript. There are quite a few browser APIs like that, and it always feels like a bit of a shame to me. Ideally there should be a JavaScript API and a declarative option, even if the declarative option isn’t as powerful.

Take form validation. To cover the most common use cases, you probably only need to use declarative markup like input type="email" or the required attribute. But if your use case gets a bit more complicated, you can reach for the Constraint Validation API in JavaScript.

I like that pattern. I wish it were an option for JavaScript-only APIs. Take the Geolocation API, for example. Right now it’s only available through JavaScript. But what if there were an input type="geolocation" ? It wouldn’t cover all use cases, but it wouldn’t have to. For the simple case of getting someone’s location (like getting someone’s email or telephone number), it would do. For anything more complex than that, that’s what the JavaScript API is for.

I was reminded of this recently when Ada Rose Cannon tweeted:

It really feels like there should be a semantic version of the share API, like a mailto: link

I think she’s absolutely right. The Web Share API has one primary use case: let the user share the current page. If that use case could be met in a declarative way, then it would have a lower barrier to entry. And for anyone who needs to do something more complicated, that’s what the JavaScript API is for.

But Pete LePage asked:

How would you feature detect for it?

Good question. With the JavaScript API you can do feature detection—if the API isn’t supported you can either bail or provide your own implementation.

There a few different ways of extending HTML that allow you to provide a fallback for non-supporting browsers.

You could mint a new element with a content model that says “Browsers, if you do support this element, ignore everything inside the opening and closing tags.” That’s the way that the canvas element works. It’s the same for audio and video—they ignore everything inside them that isn’t a source element. So developers can provide a fallback within the opening and closing tags.

But forging a new element would be overkill for something like the Web Share API (or Geolocation). There are more subtle ways of extending HTML that I’ve already alluded to.

Making a new element is a lot of work. Making a new attribute could also be a lot of work. But making a new attribute value might hit the sweet spot. That’s why I suggested something like input type="geolocation" for the declarative version of the Geolocation API. There’s prior art here; this is how we got input types for email, url, tel, color, date, etc. The key piece of behaviour is that non-supporting browsers will treat any value they don’t understand as “text”.

I don’t think there should be input type="share". The action of sharing isn’t an input. But I do think we could find an existing HTML element with an attribute that currently accepts a list of possible values. Adding one more value to that list feels like an inexpensive move.

Here’s what I suggested:

<button type=”share” value=”title,text”>

For non-supporting browsers, it’s a regular button and needs polyfilling, no different to the situation with the JavaScript API. But if supported, no JS needed?

The type attribute of the button element currently accepts three possible values: “submit”, “reset”, or “button”. If you give it any other value, it will behave as though you gave it a type of “submit” or “button” (depending on whether it’s in a form or not) …just like an unknown type value on an input element will behave like “text”.

If a browser supports button type="share”, then when the user clicks on it, the browser can go “Right, I’m handing over to the operating system now.”

There’s still the question of how to pass data to the operating system on what gets shared. Currently the JavaScript API allows you to share any combination of URL, text, and description.

Initially I was thinking that the value attribute could be used to store this data in some kind of key/value pairing, but the more I think about it, the more I think that this aspect should remain the exclusive domain of the JavaScript API. The declarative version could grab the current URL and the value of the page’s title element and pass those along to the operating system. If you need anything more complex than that, use the JavaScript API.

So what I’m proposing is:

<button type="share">

That’s it.

But how would you test for browser support? The same way as you can currently test for supported input types. Make use of the fact that an element’s attribute value and an element’s property value (which 99% of the time are the same), will be different if the attribute value isn’t supported:

var testButton = document.createElement("button");
if (testButton.type != "share") {
// polyfill

So that’s my modest proposal. Extend the list of possible values for the type attribute on the button element to include “share” (or something like that). In supporting browsers, it triggers a very bare-bones handover to the OS (the current URL and the current page title). In non-supporting browsers, it behaves like a button currently behaves.
