2024: Extra CSS At-Guidelines Than the Previous Decade Mixed

Extra occasions than I can rely, whereas writing, I get myself into random however fascinating subjects with little relation to the unique publish. In the long run, I’ve to make the straightforward however painful alternative of deleting or archiving hours of analysis and writing as a result of I do know most individuals click on on a publish with a sure expectation of what they’ll get, and I do know it isn’t me bombing them with unrelated rants about CSS.

This occurred to me whereas engaged on Monday’s article about at-rules. All I did there was deal with a variety of recipes to check browser assist for CSS at-rules. Within the course of, I started to appreciate, geez we’ve so many new at-rules — I’m wondering what number of of them are from this yr alone. That’s the rabbit gap I discovered myself in as soon as I wrapped up the article I used to be engaged on.

And guess what, my hunch was proper: 2024 has introduced extra at-rules than a complete decade of CSS.

It began once I requested myself why we obtained a selector() wrapper perform for the @helps at-rule however are nonetheless ready for an at-rule() model. I can’t pinpoint the precise reasoning there, however I’m sure rthere wasn’t a lot of a have to verify the assist of at-rules as a result of, nicely, there weren’t that a lot of them — it’s only in the near past that we obtained a windfall of at-rules.

Some historic context

So, proper round 1998 when the CSS 2 suggestion was launched, @import and @web page have been the one at-rules that made it into the CSS spec. That’s just about how issues remained till the CSS 2.1 suggestion in 2011 launched @media. After all, there have been different at-rules like — @font-face, @namespace and @keyframes to call a number of — that had already debuted in their very own respective modules. By this time, CSS dropped semantic versioning, and the specification didn’t give a real image of the entire, however moderately particular person modules organized by characteristic.

Random tangent: The final accepted consensus says we’re at “CSS 3”, however that was a decade in the past and a few even say we should always begin stepping into CSS 5. Wherever we’re is inappropriate, though it’s definitely a subject of debate taking place. Is it even helpful to have a named model?

The @helps at-rule was launched in 2011 in CSS Conditional Guidelines Module Stage 3 — Ranges 1 and a couple of don’t formally exist however seek advice from the unique CSS 1 and a couple of suggestions. We didn’t truly get assist for it in most browsers till 2015, and at the moment, the present at-rules already had widespread assist. The @helps was solely geared in the direction of new properties and values, designed to check browser assist for CSS options earlier than trying to use kinds.

The numbers

As of as we speak, we’ve a grand complete of 18 at-rules in CSS which are supported by at the least one main browser. If we have a look at the yr every at-rule was initially outlined in a CSSWG Working Draft, we are able to see all of them have been revealed at a reasonably constant charge:

If we verify the variety of at-rules supported on every browser per yr, nevertheless, we are able to see the large distinction in browser exercise:

If we simply deal with the final yr a serious browser shipped every at-rule, we are going to discover that 2024 has introduced us a whopping seven at-rules to this point!

I like little thought experiments like this. One thing you’re researching results in researching about the identical matter; out of scope, however tangentially associated. It is probably not the type of factor you bookmark and reference each day, however it’s good cocktail chatter. If nothing else, it’s affirming the sensation that CSS is shifting quick, like actually quick in a means we haven’t seen since CSS 3 first landed.

It additionally provides context for the CSS options we’ve — and don’t have. There was no at-rule() perform initially as a result of there weren’t many at-rules to start with. Now that we’ve exploded with extra new at-rules than the previous decade mixed, it might be no coincidence that simply final week the Chrome Crew up to date the perform’s standing from New to Assigned!

One final observe: the rationale I’m even eager about at-rules in any respect is that we’ve up to date the CSS Almanac, increasing it to incorporate extra CSS options together with at-rules. I’m making an attempt to fill it up and you may all the time assist by turning into a visitor author.
