CSS { In Real Life } | Web Sustainability and the Ethical Dilemma

But is it always the case that faster websites are greener websites? We reluctantly have to consider another facet: if making a website for a car manufacturer faster leads to an increase in the number of cars sold, can we really say that our website is greener?

This is very timely for me, given that Clearleft is currently engaged on a project that’s making me decidedly queasy for this exact reason—the success metrics of the project would be net negative for the world.

A long-term plan for logical properties? | Miriam Eric Suzanne

Well, now I’m really glad I wrote that post about logical properties!

We’re not there yet. So how do we get there?

Well, I don’t know for sure – but articles like this are very helpful as we try to work it out!

Let’s get logical

I was refactoring some CSS on The Session over the weekend. I thought it would be good to switch over to using logical properties exclusively. I did this partly to make the site more easily translatable into languages with different writing modes, but mostly as an exercise to help train me in thinking with logical properties by default.

All in all, it went pretty smoothly. You can kick the tyres by opening up dev tools on The Session and adding a writing-mode declaration to the body or html element.

For the most part, the switchover was smooth. It mostly involved swapping out property names with left, right, top, and bottom for inline-start, inline-end, block-start, and block-end.

The border-radius properties tripped me up a little. You have to use shorthand like border-start-end-radius, not border-block-start-inline-end-radius (that doesn’t exist). So you have to keep the order of the properties in mind:

border-{{block direction}}-{{inline-direction}}-radius

Speaking of shorthand, I also had to kiss some shorthand declarations goodbye. Let’s say I use this shorthand for something like margin or padding:

margin: 1em 1.5em 2em 0.5em;

Those values get applied to margin-top, margin-right, margin-bottom, and margin-left, not the logical equivalents (block-start, inline-end, block-end, and inline-start). So separate declarations are needed instead:

margin-block-start: 1em;
margin-inline-end: 1.5em;
margin-block-end: 2em;
margin-inline-start: 0.5em;

Same goes for shorthand like this:

margin: 1em 2em;

That needs to be written as two declarations:

margin-block: 1em;
margin-inline: 2em;

Now I’ve said it before and I’ll say it again: it feels really weird that you can’t use logical properties in media queries. Although as I said:

Now you could rightly argue that in this instance we’re talking about the physical dimensions of the viewport. So maybe width and height make more sense than inline and block.

But along comes the new kid on the block (or inline), container queries, ready to roll with container-type values like inline-size. I hope it’s just a matter of time until we can use logical properties in all our conditional queries.

The other place where there’s still a cognitive mismatch is in transforms and animations. We’ve got a translateX() function but no translate-inline(). We’ve got translateY() but no translate-block().

On The Session I’m using some JavaScript to figure out the details of some animation effects. I’m using methods like getBoundingClientRect(). It doesn’t return logical properties. So if I ever want to adjust my animations based on writing direction, I’ll need to fork my JavaScript code.

Oh, and one other thing: the aspect-ratio property takes values in the form of width/height, not inline/block. That makes sense if you’re dealing with images, videos, or other embedded content but it makes it really tricky to use aspect-ratio on elements that contain text. I mean, it works fine as long as the text is in a language using a top-to-bottom writing mode, but not for any other languages.

The self-fulfilling prophecy of React - Josh Collinsworth blog

Matcalfe’s Law in action:

Companies keep choosing React because they know there’s a massive pool of candidates who know it; candidates keep learning React because they know companies are hiring for it. It’s a self-sustaining cycle.

But the problem is:

React isn’t great at anything except being popular.

Giving your future self a little credit with progressive enhancement - Blog - Pixo | Apps, websites, and software development

We often talk about technical debt — the costs we’ll need to pay in the future when we make short-term compromises. Progressive enhancement is the opposite of that — a sort of technical credit that will make things easier for us in the future.

A good explanation of how progressive enhancement works perfectly with the idea of a minimal viable product:

We focus first on a core experience that delivers what your users are looking for, and then we start adding enhancements that will delight them.

How To Improve Largest Contentful Paint for Faster Load Times - Calibre

A no-nonsense checklist of good performance advice from Karolina.

as days pass by — Farmbound, or how I built an app in 2022

Stuart writes up the process up making a mobile game as a web app—not a native app. The Wordle effect reverberates.

It’s a web app. Works for everyone. And I thought it would be useful to explain why it is, why I think that’s the way to do things, and some of the interesting parts of building an app for everyone to play which is delivered over the web rather than via app stores and downloads.

The capture attribute is pretty nifty—and I just love that you get so much power in a declarative way:

Using :has() as a CSS Parent Selector and much more | WebKit

A terrific tour of just some of the fantastic ways you can use :has() in CSS.

The section on using it with sibling selectors blew my mind:

How often have you wanted to adjust the margins on a headline based on the element following it? Now it’s easy. This code allows us to select any h2 with a p immediately after it.

h2:has(+ p) { margin-bottom: 0; }

Amazing.

The web is a harsh manager - daverupert.com

Dave laments the increasing number of complex jobs involved in front-end (or “full-stack”) development.

But whereas I would just leave at that, Dave does something constructive and points to a potential solution—a corresponding increase of more thinsliced full-time roles like design engineering, front-end ops, and CSS engineering.

Following on from that excellent blog post about removing jQuery from gov.uk, here are the performance improvements in charts and numbers.

It may sound like 32 kb of JavaScript is nothing on today’s modern web with quick devices and fast broadband connections. But for a certain cohort of users, it makes a big difference to how they experience GOV.UK.
