Designing for Inclusion with Media Queries

The slides and notes from a great presentation by Eric Bailey that takes a really thoughtful deep dive into media types, media queries, and inclusive design.

Meet swup

This looks like a handy library for managing page transitions on sites that are not single page apps.

Here’s the code.

I’ve said it before and I’ll say it again, but I really think that this handles 80% of the justification for using a single page app architecture.

The Slow Death of Internet Explorer and the Future of Progressive Enhancement · An A List Apart Article

Oliver Williams makes the case—and shows the code—for delivering only HTML to old versions of Internet Explorer, sparing them from the kind of CSS and JavaScript that they can’t deal with it. Seems like a sensible approach to me (assuming you’re correctly building in a layered way so that your core content is delivered in markup).

Rather than transpiling and polyfilling and hoping for the best, we can deliver what the person came for, in the most resilient, performant, and robust form possible: unadulterated HTML. No company has the resources to actively test their site on every old version of every browser. Malfunctioning JavaScript can ruin a web experience and make a simple page unusable. Rather than leaving users to a mass of polyfills and potential JavaScript errors, we give them a basic but functional experience.

Super-powered layouts with CSS Variables + CSS Grid by Michelle Barker on CodePen

This article is about using custom properties and CSS grid together, but I think my favourite part is this description of how custom properties differ from the kind of variables you get from a preprocessor:

If you’re familiar with Javascript, I like to think of the difference between preprocessor variables and CSS Variables as similar to the difference between const and let - they both serve different purposes.

CSS Grid: More flexibility with minmax() by Michelle Barker on CodePen

A good use case for using minmax with CSS grid to dispense with a media query.

HTML5 Constraint Validation

The slides from a presentation by Drew on all the functionality that browsers give us for free when it comes to validating form inputs.

Half the battle of the web platform is knowing what technology is out there, ready to use. We’re all familiar with the ability to declare validation constraints in our HTML5 forms, but were you aware there’s a JavaScript API that goes along with it?

A Guide To The State Of Print Stylesheets In 2018 — Smashing Magazine

Good advice on print styles from Rachel. The browser support situation is frustrating; I suspect it’s because the people working on browsers would rather get stuck in on shinier stuff.

Wakamai Fondue

A drag-and-drop tool for examining variable fonts (kind of like FontDrop but with more sliders to play with).

I didn’t get the name until I said it out loud.

Radial Gradient Recipes | CSS-Tricks

Chris takes us on a whirlwind tour of radial gradients in CSS.

Upcoming changes to the CSS you need for variable fonts | Clagnut

Rich enumerates some changes in how you set up variable fonts. So if you’re pulling in a font that has weight as an axis, you can now add this to your @font-face rule:

font-weight: 1 999;

I’m already very excited about variable fonts—I’m going to be positively giddy by the time Ampersand rolls around (which, by the way, you should totally go to—it’s going to be sooo good!).

Grid to Flex

Una has put together this handy one-pager of flexbox fallbacks for some common grid layouts.


A demo of page transition animations by Sarah—she’s written about how she did it. I really like it as an example of progressive enhancement: you can navigate around the site just fine, but with JavaScript you get the smooth transitions as a bonus.

All of this reminds me of Jake’s proposal for navigation transitions in the browser. I honestly think this would solve 80% of the use-cases for single page apps.

Animating Progress - Snook.ca

Jonathan goes down the rabbit hole of trying to animate a progress element.

Inside CSS | Clearleft

If you’ve ever wondered what it would be like to be a fly on the wall at a CSS Working Group meeting, Richard has the inside scoop.

The consensus building is vital. Representatives from all the major browsers were in the room, collaborating closely by proposing ideas and sharing implementations. But most fundamentally they were agreeing together what should go in the specifications, because what goes in the specs is what gets built and ends up in the hands of users.

:focus-visible and backwards compatibility

Patrick is thinking through a way to implement :focus-visible that’s forwards and backwards compatible.

Best Practices With CSS Grid Layout — Smashing Magazine

A great set of answers from Rachel to frequently asked questions about CSS grid. She addresses the evergreen question of when to use flexbox and when to use grid:

I tend to use Flexbox for components where I want the natural size of items to strongly control their layout, essentially pushing the other items around.

A sign that perhaps Flexbox isn’t the layout method I should choose is when I start adding percentage widths to flex items and setting flex-grow to 0. The reason to add percentage widths to flex items is often because I’m trying to line them up in two dimensions (lining things up in two dimensions is exactly what Grid is for).

Keep Pixelated Images Pixelated as They Scale | CSS-Tricks

This is a potentially useful bit of CSS that I had no idea existed.

Notes on `lang` by Taylor Hunt on CodePen

A really deep dive into the lang attribute, and the :lang() pseudo-class (hitherto unknown to me). This is all proving really useful for a little side project I’m working on.

Think like it’s 1995; code like it’s 2035 - Grayscale

This is such a great write-up of the workshop I did in Hong Kong!

Jeremy, it was a pleasure to work with you and you are always welcome here in Hong Kong!

If you fancy having this one-day workshop at your company, get in touch.

Starability - Accessible rating system demo

Accessible star ratings (progressively enhanced from radio buttons) with lots of animation options. The code is on Github.
