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.

Using CSS variables correctly - Mike Riethmuller

Mike examines the real power of CSS custom properties compared to Sass variables—they can change at runtime.

I’m convinced that in almost all cases, responsive design logic should now be contained in variables. There is a strong argument too, that when changing any value, whether in a media query or an element scope, it belongs in a variable. If it changes, it is by definition a variable and this logic should be separated from design.

How the minmax() Function Works

A great description of one of the most powerful features in CSS Grid.

This function opens the door to us being able to write much more powerful and succinct CSS by allowing us to set, as a value for a grid track, a function including both a minimum and maximum value.

Responsive Design for Motion | WebKit

A really great overview of using prefers-reduced-motion to tone down CSS animations.

This post was written by James Craig, and I’m going to take this opportunity to say a big “thank you!” to James for all the amazing accessibility work he has been doing at Apple through the years. The guy’s a goddamn hero!

A Love Letter to CSS

My argument is relatively simple: creating a comprehensive styling mechanism for building complex user interfaces is startlingly hard, and every alternative to CSS is much worse. Like, it’s not even close.

An introduction to CSS Grid | Charlotte Jackson, Front-end developer

Charlotte has caught the CSS Grid bug. I absolutely love her step-by-step explanation—it’s really clear, and manages to be brief but thorough at the same time.

It’s time to be more experimental and push the boundaries with layouts.

Styling the Patterns Day site

Once I had a design direction for the Patterns Day site, I started combining my marked-up content with some CSS. Ironically for an event that’s all about maintainability and reusability, I wrote the styles for this one-page site with no mind for future use. I treated the page as a one-shot document. I even used ID selectors—gasp! (the IDs were in the HTML anyway as fragment identifiers).

The truth is I didn’t have much of a plan. I just started hacking away in a style element in the head of the document, playing around with colour, typography, and layout.

I started with the small-screen styles. That wasn’t a conscious decision so much as just the way I do things automatically now. When it came time to add some layout for wider viewports, I used a sprinkling of old-fashioned display: inline-block so that things looked so-so. I knew I wanted to play around with Grid layout so the inline-block styles were there as fallback for non-supporting browsers. Once things looked good enough, the fun really started.

I was building the site while I was in Seattle for An Event Apart. CSS Grid layout was definitely a hot topic there. Best of all, I was surrounded by experts: Jen, Rachel, and Eric. It was the perfect environment for me to dip my toes into the waters of grid.

Jen was very patient in talking me through the concepts, syntax, and tools for using CSS grids. Top tip: open Firefox’s inspector, select the element with the display:grid declaration, and click the “waffle” icon—instant grid overlay!

For the header of the Patterns Day site, I started by using named areas. That’s the ASCII-art approach. I got my head around it and it worked okay, but it didn’t give me quite the precision I wanted. I switched over to using explicit grid-row and grid-column declarations.

It’s definitely a new way of thinking about layout: first you define the grid, then you place the items on it (rather than previous CSS layout systems where each element interacted with the elements before and after). It was fun to move things around and not have to worry about the source order of the elements …as long as they were direct children of the element with display:grid applied.

Without any support for sub-grids, I ended up having to nest two separate grids within one another. The logo is a grid parent, which is inside the header, also a grid parent. I managed to get things to line up okay, but I think this might be a good use case for sub-grids.

The logo grid threw up some interesting challenges. I wanted each letter of the words “Patterns Day” to be styleable, but CSS doesn’t give us any way to target individual letters other than :first-letter. I wrapped each letter in a b element, made sure that they were all wrapped in an element with an aria-hidden attribute (so that the letters wouldn’t be spelled out), and then wrapped that in an element with an aria-label of “Patterns Day.” Now I could target those b elements.

For a while, I also had a br element (between “Patterns” and “Day”). That created some interesting side effects. If a br element becomes a grid item, it starts to behave very oddly: you can apply certain styles but not others. Jen and Eric then started to test other interesting elements, like hr. There was much funkiness and gnashing of specs.

It was a total nerdfest, and I loved every minute of it. This is definitely the most excitement I’ve felt around CSS for a while. It feels like a renaissance of zen gardens and layout reservoirs (kids, ask your parents).

After a couple of days playing around with grid, I had the Patterns Day site looking decent enough to launch. I dabbled with some other fun CSS stuff in there too, like gratuitous clip paths and filters when hovering over the speaker images, and applying shape-outside with an image mask.

Go ahead and view source on the Patterns Day page if you want—I ended up keeping all the CSS in the head of the document. That turned out to be pretty good for performance …for first-time visits anyway. But after launching the site, I couldn’t resist applying some more performance tweaks.

Springer Nature frontend playbook: house style guide

I like it when organisations share their in-house coding styles. This one from Springer Nature not only has guides for HTML, CSS, and JavaScript, but it also has a good primer on progressive enhancement.

There are maps for these territories | Clearleft

A great piece from Danielle on the different mental models needed for different languages. When someone describes a language—like CSS—as “broken”, it may well be that there’s a mismatch in mental models.

CSS isn’t a programming language. It’s a stylesheet language. We shouldn’t expect it to behave like a programming language. It has its own unique landscape and structures, ones that people with programming language mental maps might not expect.

I believe that this mismatch of expectation is what has led to the current explosion of CSS-in-JS solutions. Confronted with a language that seems arbitrary and illogical, and having spent little or no time exposed to the landscape, developers dismiss CSS as ‘broken’ and use systems that either sweep it under the rug, or attempt to force it into alignment with the landscape of a programming language — often sacrificing some of the most powerful features of CSS.

Inclusively Hidden | scottohara.me

Comparing different ways to hide content accessibly:

There are three reasons behind hiding content in an interface, and it’s important to identify what those reasons are, as they will correlate with the appropriate technique needed to hide such content.

  1. Temporarily Hidden Content
  2. Purposefully Visually Hidden Content
  3. Purposefully Visual-Only Content

Getting griddy with it

I had the great pleasure of attending An Event Apart Seattle last week. It was, as always, excellent.

It’s always interesting to see themes emerge during an event, especially when those thematic overlaps haven’t been planned in advance. Jen noticed this one:

I remember that being a theme at An Event Apart San Francisco too, when it seemed like every speaker had words to say about ill-judged use of Bootstrap. That theme was certainly in my presentation when I talked about “the fallacy of assumed competency”:

  1. large company X uses technology Y,
  2. company X must know what they are doing because they are large,
  3. therefore technology Y must be good.

Perhaps “the fallacy of assumed suitability” would be a better term. Heydon calls it “the ‘made at Facebook’ fallacy.” But I also made sure to contrast it with the opposite extreme: “Not Invented Here syndrome”.

As well as over-arching themes, it was also interesting to see which technologies were hot topics at An Event Apart. There was one clear winner here—CSS Grid Layout.

Microsoft—a sponsor of the event—used An Event Apart as the place to announce that Grid is officially moving into development for Edge. Jen talked about Grid (of course). Rachel talked about Grid (of course). And while Eric and Una didn’t talk about it on stage, they’ve both been writing about the fun they’ve been having having with Grid. Una wrote about 3 CSS Grid Features That Make My Heart Flutter. Eric is documenting the overall of his site with Grid. So when we were all gathered together, that’s what we were nerding out about.

The CSS Squad.

There are some great resources out there for levelling up in Grid-fu:

With Jen’s help, I’ve been playing with CSS Grid on a little site that I’m planning to launch tomorrow (he said, foreshadowingly). I took me a while to get my head around it, but once it clicked I started to have a lot of fun. “Fun” seems to be the overall feeling around this technology. There’s something infectious about the excitement and enthusiasm that’s returning to the world of layout on the web. And now that the browser support is great pretty much across the board, we can start putting that fun into production.

Here’s a handy interface if you want to get your head around named areas in CSS Grid, also known as doing layout with ASCII art.

Eric’s Archived Thoughts: Grid-Powered Drop Quotes

I’ve been digging into CSS Grid a lot during the past week, so this post from Eric is very timely. On the surface it looks like a fairly simple use case but as you read through the explanation, it starts to become clear that the underlying thinking could be used in a lot of situations.

And, yes, like Eric, I too have been bitten by the Grid bug:

I’m working on my first redesign in a dozen years. If that doesn’t give you some sense of the power of Grid, well, I just don’t know what will.
