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.
A quick visual guide to CSS Grid properties and values.
Neither matters all that much and you can use every method on the same project without the universe imploding.
Some interesting approaches in the comments too.
This is a really clear explanation of how CSS works.
Paul finishes up his excellent three part series by getting down to the brass tacks of designing and building components on the web …and in cities. His closing provocation has echoes of Heydon’s rallying cry.
If you missed the other parts of this series, they are:
Paul is turning his excellent talk on design systems into a three part series. Here’s part one, looking at urban planning from Brasília to London.
A whole lotta CSS properties and values gathered together in one place. The one-page view is a bit overwhelming, but search and collections can get you to the right bit lickety-split.
Harry demonstrates a really good use for CSS custom properties—allowing users to theme an interface.

Two sides of a debate on progressive enhancement…
Andrey “Rarst” Savchenko wrote Progressive enhancement — JS sites that work:
Joe Hoyle disagrees:
Caspar acknowledges this:
I don’t have any problem buying into pragmatism as the main and often pressing reason for not investing into a no-JS fallback. The idealistic nature of a design directive like progressive enhancement is very clear to me, and so are typical restrictions in client projects (budgets, deadlines, processes of decision making).
But concludes that by itself that’s not enough reason to ditch such a fundamental technique for building a universal, accessible web:
Ain’t nobody got time for progressive enhancement always, maybe. But entirely ditching principle as a compass for resilient decision making won’t do.
A wonderful collection of treasures excavated from GeoCities. Explore, enjoy, and remember what a crime it is that Yahoo wiped out so much creativity and expression.
It will come as no surprise that I agree with every single word that Tim has written here.
I’m at Disney World for a special edition of An Event Apart, so this lightning talk from Dan Williams seems appropriate to revisit.
I think I concur with this list. Although I guess it’s worth remembering that, given the size of the CSS spec, this isn’t an overly-long list.
It’s interesting that quite a few of them are about how things are named. It’s almost as if that’s one of the, say, two hardest things in computer science.
I’m not sure how I managed to miss this site up until now, but it’s right up my alley: equal parts urban planning, ethnography, and food science.
Paris Review – “One Murder Is Statistically Utterly Unimportant”: A Conversation with Warren Ellis, Molly Crabapple
Molly Crabapple interviews Warren Ellis. Fun and interesting …much like Molly Crabapple and Warren Ellis.
Ben proposes an alternative to archive.org: changing the fundamental nature of DNS.
Regarding the boo-hooing of how hard companies have it maintaining unprofitable URLs, I think Ben hasn’t considered the possibility of a handover to a cooperative of users—something that might yet happen with MySpace (at least there’s a campaign to that effect; it will probably come to naught). As Ben rightly points on, domain names are leased, not bought, so the idea of handing them over to better caretakers isn’t that crazy.
Another responsive design case study. This one’s got numbers too.
