Responsive Letter Spacing – Cloud Four

Another clever use of clamp() and calc() for web typography, but this time it’s adjusting letter-spacing.

I’m more proud of these 128 kilobytes than anything I’ve built since | by Mike Hall | Jul, 2025 | Medium

I don’t normally link to articles on Medium—I respect you too much—and I do wish this were written on Mike Hall’s own site, but this is just too good not to share.

And don’t dismiss this as a nostalgiac case study from the past:

At no point did the constraints make the product feel compromised. Users on modern devices got a smooth experience and instant feedback, while those on older devices got fast, reliable functionality. Users on feature phones got the same core experience without the bells and whistles.

The constraints forced us to solve problems in ways we wouldn’t have considered otherwise. Without those constraints, we could have just thrown bytes at the problem, but with them every feature had to justify itself. Core functionality had to work everywhere, and without JavaScript crutches proper markup became essential.

This experience changed how I approach design problems. Constraints aren’t a straitjacket, keeping us from doing our best work; they are the foundation that makes innovation possible. When you have to work within severe limitations, you find elegant solutions that scale beyond those limitations.

Taking RWD To The Extreme — Smashing Magazine

Some really great advice here:

• Use native layout systems
• Start with semantic HTML
• Use fluid type with fluid space
• Always bet on progressive enhancement
• Trust the browser
• Ditch the “physical” CSS

Hyper-responsive web components | Trys Mudford

Trys describes exactly the situation where you really do need to use the Shadow DOM in a web component—as opposed to just sticking to HTML web components—, and that’s when the component is going to be distributed and you have no idea where:

This component needed to be incredibly portable, looking great on any third-party website, in any position, at any viewport, with any amount of content. It had to be a “hyper-responsive” component.

I really like the newly-launched website for this year’s XOXO festival. I like that the design is pretty much the same for really small screens, really large screens, and everything in between because everything just scales. It’s simultaneously a flyer, a poster, and a billboard.

Trys has written about the websites he’s noticed using fluid type and spacing: There it is again, that fluid feeling.

I know what he means. I get a similar feeling when I’m on a site that adjusts fluidly to any browser window—it feels very …webby.

I’ve had this feeling before.

When responsive design was on the rise, it was a real treat to come across a responsive site. After a while, it stopped being remarkable. Now if I come across a site that isn’t responsive, it feels broken.

And now it’s a treat to come across a site that uses fluid type. But how long will it be until it feels unremarkable? How will it be until a website that doesn’t use fluid type feels broken?

Printing music with CSS grid

Laying out sheet music with CSS grid—sounds extreme until you see it abstracted into a web component.

We need fluid and responsive music rendering for the web!

Extending Responsive Video with HTML Web Components | Scott Jehl, Web Designer/Developer

Scott gives a thorough step-by-step walkthrough of building an HTML web component, in this case for responsive video:

In this post, I’m going to talk briefly about responsive video, but most of the post will be about using HTML web components to extend native video behavior in very helpful ways. But even if you’re not particularly interested in video development, stick around as I’ll demonstrate how to build an HTML Web Component to progressively enhance anything you need.

Getting started with CSS container queries | MDN Blog

Michelle has written a detailed practical guide to container queries here.

I had a lot of fun making the website for Patterns Day.

If you’re interested in the tech stack, here’s what I used:

1. HTML
2. CSS

Actually, technically it’s all HTML because the styles are inside a style element rather than a separate style sheet, but you know what I mean. Also, there is technically some JavaScript but all it does is register a service worker that takes care of caching and going offline.

I didn’t use any build tools. There was no pipeline. There is no node_modules folder filling up my hard drive. Nothing was automated. The website was hand-crafted the long hard stupid way.

I started with the content. I wrote out the words and marked them up with the most appropriate HTML elements.

Time to layer on the presentation.

For the design, I turned to Michelle for help. I gave her a brief, describing the vibe of the conference, and asked her to come up with an appropriate visual language.

Crucially, I asked her not to design a website. Instead I asked her to think about other places where this design language might be used: a poster, social media, anything but a website.

Partly I was doing this for my own benefit. If you give me a pixel-perfect design for a web page and tell me to code it up, either I won’t do it or I won’t enjoy it. I just don’t get any motivation out of that kind of direct one-to-one translation.

But give me guardrails, give me constraints, give me boundary conditions, and off I go!

Michelle was very gracious in dealing with such a finicky client as myself (“Can you try this other direction?”, “Hmm… I think I preferred the first one after all!”) She delivered a colour palette, a type scale, typeface choices, and some wonderful tiling patterns …it is Patterns Day after all!

With just a few extra lines of CSS, the basic typography was in place.

I started layering on the colours. Even though this was a one-page site, I still made liberal use of custom properties in the CSS. It just feels good to be able to update one value and see the results, well …cascade.

I had a lot of fun with the tiling background images. SVG was the perfect format for these. And because the tiles were so small in file size, I just inlined them straight into the CSS.

By this point, I felt like I was truly designing in the browser. Adjusting spacing, playing around with layout, and all that squishy stuff. Some of the best results came from happy accidents—the way that certain elements behaved at certain screen sizes would lead me into little experiments that yielded interesting results.

I’m not sure it’s possible to engineer that kind of serendipity in Figma. Figma was the perfect tool for exploring ideas around the visual vocabulary, and for handing over design decisions around colour, typography, and texture. But when it comes to how the content is going to behave on the World Wide Web, nothing beats a browser for fidelity.

By this point I was really sweating the details, like getting the logo just right and adjusting the type scale for different screen sizes. Needless to say, Utopia was a godsend for that.

I was also checking back in with Michelle to get her take on design decisions I was making.

I could’ve kept tinkering but the diminishing returns were a sign that it was time to put this out into the world.

It felt really good to work on a web page like this. It felt like I was getting my hands into the soil of the web. I don’t think it’s an accident that the result turned out to be very performant.

Getting hands-on like this stops me from getting rusty. And honestly, working with CSS these days is a joy. There’s such power to be had from using var() in combination with functions like calc() and clamp(). Layout is a breeze with flexbox and grid. Browser differences are practically non-existent. We’ve never had it so good.

Here’s something I noticed about my relationship to CSS; my brain has finally made the switch to logical properties. Now if I’m looking at some CSS and I see left, right, top, or bottom, it looks like a bug to me. Those directional properties feel loaded with assumptions whereas logical properties feel much more like working with the grain of the web.

Clamp calculator | Utopia

Oh, this is a nice addition to the Utopia set of tools: when you don’t need a full-on type scale but you still want to figure out fluid clamp() values, the clamp calculator has you covered.

It’s got permalinks too!

zachleat/table-saw: A small web component for responsive `table` elements.

Now, this is how you design a web component. It’s a progressive enhancement.

Wrap your existing table element inside table-saw and it will behave responsively. If anything goes wrong with the JavaScript, the fallback is the regular table that’s already in your markup.

I just wish the installation didn’t assume that you’re using npm …it’s not really “zero dependency” if it depends on that.

The ideal viewport doesn’t exist

Some lovely scroll-driven animations illustrate this great little microsite.

There’s something very pleasy about the chunky design that harkens back to the Zeldmanesque early web.

On Container Queries, Responsive Images, and JPEG-XL – Cloud Four

Container queries can’t be used in the sizes attribute for responsive images. Here, Jason breaks down why that is (spoiler: it’s the lookahead pre-parser) and segues into a truly long term solution: a “magical” image format.

If you’ve ever thought it felt weird to put media conditions inside the HTML for responsive images, this will resonate.
