CSSWG Minutes Telecon (2024-12-04): Simply Use Grid vs. Show: Masonry

The CSS Working Group (CSSWG) meets weekly (or near it) to debate and rapidly resolve points from their GitHub that may in any other case be misplaced within the back-and-forth of discussion board dialog. Whereas every assembly brings attention-grabbing dialog, this previous Wednesday (December 4th) was particular. The CSSWG met to attempt to lastly squash a debate that has been happening for 5 years: whether or not Masonry must be part of Grid or a separate system.

I’ll attempt to summarize the present state of the talk, however in case you are in search of the lengthy model, I like to recommend studying CSS Masonry & CSS Grid by Geoff and Selecting a Masonry Syntax in CSS by Miriam Suzanne.

In 2017, it was steadily requested whether or not Grid may deal with masonry layouts; layouts the place the columns (or the rows) may maintain erratically sized objects with out gaps in between. Whereas this is only one of a number of potentialities with masonry, you’ll be able to take into consideration the format popularized by Pinterest:

In 2020, Firefox launched a prototype during which masonry was built-in into the CSS Grid format module. The principle voice towards it was Rachel Andrew, arguing that it must be its personal, separate factor. Since then, the talk has escalated with two proposals from Apple and Google, arguing for and towards a grid-integrated syntax, respectively.

There have been some technical worries towards a grid-masonry implementation that have been since resolved. What it’s a must to know is that this: proper now, it’s a matter of syntax. To be particular, which syntax is

a. is less complicated to study for authors and

b. how would possibly this choice affect attainable future developments in a single or each fashions (or CSS normally).

Within the center, the W3C Technical Structure Group (TAG) was requested for enter on the difficulty which has prompted an effort to unify the 2 proposals. Either side have introduced robust arguments to the desk over a sequence of posts, and within the following assembly, they have been requested to put these arguments as soon as once more in a presentation, with the hope of reaching a consensus.

The Battle of PowerPoints

Alison Maher representing Google and an advocate of implementing Masonry as a brand new show worth, opened the assembly with a presentation. The details have been:

A number of properties behave otherwise between masonry and grid.

Higher defaults when setting show: masonry, one thing that Rachel Andrew just lately argued for.

There was an argument towards show: masonry since fallbacks could be extra prolonged to implement, whereas in a grid-integrated the fallback to grid is already there. Alison Maher refutes this since “needing one is a short lived downside, so [we] ought to concentrate on the longer term,” and that “authors ought to make express fallback, to keep away from surprises.”

“Positioning in masonry is less complicated than grid, it’s solely positioned in 1 axis as an alternative of two.”

Shorthands are additionally higher: “Grid shorthand is difficult, onerous to make use of. Masonry shorthand is less complicated as a result of don’t want to recollect the order.”

“Placement works otherwise in grid vs masonry” and “alignment can be very totally different”

There might be “different modifications for submasonry/subgrid that may result in divergences.”

“Integrating masonry into grid will result in spec bloat, might be more durable to show, and result in developer confusion.”

alisonmaher: “Conclusion: masonry must be a separate show sort”

Jen Simmons, representing the WebKit group and advocate of the “Simply Use Grid” method adopted with one other presentation. On this facet, the details have been:

Writer studying could possibly be skewed since “a brand new format sort creates a separate instrument with separate syntax that’s related however not the identical as what exists […]. They’re acquainted however not fairly the identical”

The Chrome proposal would add round 10 new properties. “We don’t consider there’s a compelling argument so as to add so many new properties to CSS.”

“Chromium argues that their new syntax is extra comprehensible. We disagree, simply use grid-auto-flow“

“Whenever you format rows in grid, template syntax is a bit totally different — you stack the template names to bodily diagram the names for the rows. Simply Use Grid re-uses this syntax precisely; however new masonry format makes use of the column syntax for rows”

“Different distinction is the auto-flow — grid’s signifies the first fill route, Chrome believes this doesn’t make sense and adjusted it to match the orientation of strains”

“Chrome argues that new show sort permits higher defaults — however the defaults suggest aren’t good […] it doesn’t fairly work as simply as claimed [see article] requires deep understanding of autosizing”

“Simpler to modify, e.g. at breakpoints or progressive enhancement”

“Follows CSS design rules to re-use what already exists”

The TAG assessment

After two shows with compelling arguments, Lea Verou (additionally a member of the TAG) adopted with their enter.

lea: We did a TAG assessment on this. My opinion is totally mirrored there. I believe the arguments WebKit group makes are compelling. We thought not solely ought to masonry be a part of grid, however ought to go additional. Numerous arguments for integrating is that “grid is just too onerous”. In that case we must always make grid issues simpler. Complicated issues are attainable, however easy issues aren’t really easy.

Large a part of Google’s argument is defaults, however we may simply have smarter defaults — there’s precedent for this in CSS if we determined that may assist ergonomics We agree that switching between grid vs. masonry is frequent. Grid is likely to be a barely higher fallback than nothing, however minor argument as a result of folks can use @helps. Introducing all these new properties rising the API surfaces that authors have to study. Much less they’ll port over. Even when we are saying we might be disciplined, expertise reveals that we received’t. Even when not intentional, unintentional. DRY – don’t have a number of sources of fact

One in every of arguments towards masonry in grid is that grids are 2D, however truly in graphic design grids have been typically 1D. I agree that almost all masonry use instances want easier grids than common grid use instances, however which means we must always make these grids simpler to outline for each grid and masonry. The extra we seemed into this, we understand there are 3 totally different format modes that provide you with 2D association of kids. We advisable not simply make masonry a part of grid, however discover methods of integrating what we have already got higher may we give you a shorthand that units grid-auto-flow and flex-direction, and promote that for format route normally? Then authors solely have to study one management for it.

The controversy

All was laid out onto the desk, it was solely left what different members needed to say.

oriol: Drawback with Jen Simmons’s reasoning. She stated the proposed masonry-direction property could be new syntax that doesn’t match grid-auto-flow property, however this property matches flex-direction property so as an alternative of making an attempt to be near grid, tries to be near flexbox. Nearer to grid is a selection, could possibly be in keeping with various things.

astearns: One query I requested is, has anybody modified their thoughts on which proposal they help? I personally have. I believed that separate show property made much more sense, when it comes to designing the function and I used to be very daunted by the concept we’d have to think about each grid and masonry for any new growth in both appeared sticky to me however the TAG argument satisfied me that we must always do the work of integrating these items.

TabAtkins: Thanks for setting that up for me, as a result of I’m going to refute the TAG argument! I believe they’re improper on this case. You’ll be able to draw a variety of surface-level connections between Grid and Masonry, and Flexbox, and different hypothetical layouts however once you truly take a look at particulars of how they work, behaviors each is able to, they’re fairly distinct for those who attempt to mix collectively, it will be an unholy mess of conflicting constraints — e.g. flexing in objects of masonry or grid otherwise you’d have a bizarre mish-mash of, “the 2D format.

However for those who name it a flex you get entry to those properties, name it grid, entry to those different properties concrete instance, “pillar” instance talked about in webKit weblog put up, that wasn’t appropriate with the bottom ideas in masonry and flex as a result of it desires a shared block formatting context grid and many others have totally different formatting contexts, can’t use floats.

lea: truly, the TAG argument was that format appears to truly be a continuum, and syntax ought to accommodate that fairly than forcing one in all two extremes (present flex vs present grid).

The controversy saved backwards and forwards till there was an try and set a common north star to observe.

jyasskin: Needed to emphasise a pair features of TAG assessment. It appears very nice to maintain the property from Chrome proposal that you just don’t should study each, can simply study to do masonry with out studying all of Grid even when that’s in a unified system maybe nonetheless outline masonry shorthand, and have it set grid propertie

jensimmons: To create a easy masonry-style format in Grid, you simply want 3 strains of code (4 with a spot). It’s fairly easy.

jyasskin: Most consensus a part of TAG suggestions was to share properties each time attainable. Not essential to share the identical ‘show’ values; may outline totally different ‘show’ values however share the properties. One factor we didn’t like about unified proposal was grid-auto-flow within the unified proposal, the place some values have been ignored. Yeah, that is the usability level I’m pounding on

One other Cut up Determination

Regardless of all, it seemed like no person was freely giving, and the talk appeared caught as soon as once more:

astearns: I’m not listening to a approach ahead but. In some unspecified time in the future, one of many camps goes to should concede with the intention to transfer this ahead.

lea: What if we do a straw ballot. To not determine, however to determine how far are we from consensus? +1 lea

The votes have been forged and the outcomes have been… break up.

florian: although we may nonetheless not attain consensus, I need to thank either side for presenting clear arguments, densely packed, effectively delivered. I’ll return to the shows, and revisit some factors, it actually was informative to current the way in which it was.

That’s all of us, a break up choice! There isn’t a desire for both of the 2 proposals and implementing one thing with such combined opinions is one thing no person would approve. After just a little over 5 years of debate, I believe this assembly is one more good signal {that a} new proposal addressing the issues of either side must be thought-about, however that’s only a private opinion. To me, masonry (or no matter identify it could be) is a crucial step in CSS format that will form future layouts, it shouldn’t be rushed so till then, I’m more than pleased to attend for a proposal that satisfies either side.
