Inside a super fast CSS engine: Quantum CSS (aka Stylo) ★ Mozilla Hacks – the Web developer blog

Lin gives a deep dive into Firefox’s new CSS engine specifically, but this is also an excellent primer on how browsers handle CSS in general: parsing, styling, layout, painting, compositing, and rendering.

If you really dislike FOUT, `font-display: optional` might be your jam | CSS-Tricks

Everyone’s been talking about font-display: swap as a way of taking the pain out of loading web fonts, but here Chris looks at font-display: optional and font-display: fallback as well.

Shadow DOM: fast and encapsulated styles – Monica Dinculescu

Monica explains how Shadow DOM could be the perfect answer for scoping CSS:

We didn’t have style encapsulation, so we started naming things “the right way” with BEM, so that we didn’t accidentally stomp over each other’s styles. We wanted to be able to author CSS from inside a JavaScript component, so we started using CSS-in-JS. We needed all these tools, because “the platform” (read: the browsers that be) wasn’t there, and building these tools showed that there was a need to move forward. For style encapsulation, Shadow DOM is the platform moving forward.

Although, in a way, Shadow DOM is also another flavour of CSS-in-JS:

Before you complain that using a Shadow DOM and Web Components means that it absolutely requires JavaScript: this is true.

CSS: Current, Soon, Someday (Web Directions Code 2017) // Speaker Deck

Oh, how I wish I could’ve been at Web Directions Code in Melbourne to see this amazing presentation by Charlotte. I can’t quite get over how many amazing knowledge bombs she managed to drop in just 20 minutes!

Shoelace.css: a back to the basics CSS starter kit

A starter kit of CSS that gives you some basic styles that you can tweak with custom properties.

For when you don’t need the whole boot.


Shoelace doesn’t ship with a grid system because you don’t need one. You should use the CSS Grid Layout instead.

I approve this message!

Tooltips & Toggletips

Another great deep dive by Heydon into a single interface pattern. This time it’s the tooltip, and its cousin, the toggletip.

There’s some great accessibility advice in here.

rachelandrew/gridbugs: A curated list of Grid interop issues

Rachel is maintaining this (short) list of browser bugs with CSS Grid, inspired by the excellent Flexbugs.

Grid shipped into browsers](https://gridbyexample.com/browsers) in a highly interoperable state, however there are a few issues - let’s document any we find here.

Testing the accessibility of pattern libraries

Riffing on Rachel’s talk at Patterns Day:

At the Patterns Day conference last month, Rachel Andrew mentioned something interesting about patterns. She said that working with reusable interface components, where each one has its own page, made her realise that those work quite well as isolated test cases. I feel this also goes for some accessibility tests: there is a number of criteria where isolation aids testing.

Hidde specifically singles out these patterns:

  • Collapsible (“Show/hide”)
  • Form field
  • Video player

Progressively Enhancing CSS Layout: From Floats To Flexbox To Grid – Smashing Magazine

A great example of progressive enhancement in action.

You can perfectly use CSS grid layout today if you don’t expect exactly the same appearance in every single browser, which isn’t possible to achieve nowadays anyway. I’m well aware that this decision isn’t always up to us developers, but I believe that our clients are willing to accept those differences if they understand the benefits (future-proof design, better accessibility and better performance). On top of that, I believe that our clients and users have — thanks to responsive design — already learned that websites don’t look the same in every device and browser.

Against the grain | susan jean robertson

I’m looking for work. I’d prefer to work remotely with a product team and to work in the areas I love: accessibility, CSS, and HTML. But it turns out those three things are considered “easy” in the industry right now. Which is fascinating because if you talk to anyone who uses assistive technology to surf the web or who doesn’t use a mouse, or who is accessing content in a different manner, you’ll find out it isn’t so easy.

Somebody hire Susan already!

Patterns Day 2017: Rachel Andrew on Vimeo

Rachel’s fantastic talk from Patterns Day. There’s a lot of love for Fractal specifically, but there are also some great points about keeping a pattern library in sync with a live site, and treating individual components as reduced test-cases.

Well, well, well …following on from my post about container queries, it turns out that Eric has also been thinking about wrangling custom properties. He’s even written some code.

Time for another video from Patterns Day. Here’s Sareh Heidari walking us through Grandstand, the CSS framework at the BBC.

CSS is Awesome | CSS-Tricks

Geek humour is no laughing matter, as Chris demonstrates here with his thorough dissection of that coffee mug.

CSS is weird. It’s unlike any other code, and that makes a lot of programmers uncomfortable. But used wisely it can, in fact, be awesome.

It’s not often I say this, but read the comments.

Is it really safe to start using CSS Grid Layout?

Rachel uncovers a great phrase for dealing with older browsers:

It isn’t your fault, but it is your problem.

She points to multiple ways of using CSS Grid today while still providing a decent experience for older browsers.

Crucially, there’s one message that hasn’t changed in fifteen years:

Websites do not need to look the same in every browser.

It’s crazy that there are still designers and developers who haven’t internalised this. And before anyone starts claiming that the problem is with the clients and the bosses, Rachel has plenty of advice for talking with them too.

Your job is to learn about new things, and advise your client or your boss in the best way to achieve their business goals through your use of the available technology. You can only do that if you have learned about the new things. You can then advise them which compromises are worth making.

Fixing fieldsets — That Emil is Emil Björklund

This is an excellent proposal from Emil. If we can apply display: contents to fieldsets, then we would finally have a way of undoing the byzantine browser styles that have hindered adoption of this element. This proposal also ensures backwards compatibility so there’d be no breakage of older sites:

The legacy appearance of fieldsets probably needs to be preserved for compatibility reasons. But display: contents is not supported in any old browsers, and is most likely used on exactly zero sites using the legacy look of fieldsets.

Whaddya say, browser makers?

Sticky headers

A three-part series by Remy looking at one interface pattern (a sticky header) and how his code evolved and changed:

  1. Sticky headers
  2. Smooth scroll & sticky navigation
  3. CSS sticky nav & smooth scroll

Aspect Ratios in CSS are a Hack | Bram.us

Bram hopes for a way to define aspect ratios natively in CSS. We can sort of manage it now, but all the solutions are pretty hacky.

Form validation taken to the extreme. If you want to know more about how it was done, there’s an article explaining the markup and CSS.

Oh No! Our Stylesheet Only Grows and Grows and Grows! (The Append-Only Stylesheet Problem) | CSS-Tricks

I think Chris is on to something here when he identifies one of the biggest issues with CSS growing out of control:

The developers are afraid of the CSS.
