I will never understand the bizarre scene of the web's smug collective declaration that tables were dead and not to be used juxtaposed against the years it took to regain the ability to reliably center things. Assuming one agrees that we even did regain it.
Related: I also love when I can't paste tabular data into Excel/etc. anymore
For the record, I don't hate the idea of stylesheets, but...sheesh
I’ve gotten in several arguments over the years where webdevs insisted on showing tabular data using flexbox or hardcoded div widths or worse. They insisted that html tables were never ever to be used and couldn’t be persuaded.
I agree, but it is funny to me that your Hacker News comment is itself a table. It's in the same vein as "don't freak out, but there's a spooky skeleton inside you!"
Even for layout, CSS took a long time to catch up with tables in some areas. Tables were not designed for layout, but there's a lot of aspects to them which are easier to grasp and work with than trying to get the same effect with early CSS.
They shamed everybody into the torturous use of floats for layout and then eventually, about 15 years later, added layout features back into a layout language.
I try to politely debate the proponents with each hype cycle giving them the benefit of the doubt. They lost the "lets get rid of tables" debate quite miserably. I would quickly slap something together in jsfiddle, they would try recreate it. Adding some col- and/or rowspan programmatically for cells with the same value. Give an rgba color to rows and nth cells (columns). Resizing columns by size of cell content. It took tons of ugly css to replicate. Pasting the table into a wysiwyg editor is something they can never hope to re-create.
Usually I declare victory when they say that tables might get depreciated in the future.
They at one point really wanted to get rid of framesets. I asked how to make the classic scrollable resizable side top bottom UI in pure CSS. We've tried for hours, everything we tried looked ugly and didn't fully work. framesets are here to stay now :)
I still have one of the funnier "how to make this without tables?" challenges. It's not a very good example of the use of tables but did make me laugh.
>Give an rgba color to rows and nth cells (columns).
that sounds like a use for tables, so I find it difficult to imagine a non-table layout that would want this.
>Resizing columns by size of cell content.
I can sort of see this as a requirement for non-table layouts that would not work well, however my experience from table time was that was one of the biggest irritants at least for me, that columns would haphazardly resize based on what was in them, and sometimes you wanted them to and sometimes not. As a general rule I found it better design wise to truncate text rather than have things expanding and contracting in response to what copy editors were doing.
>framesets are here to stay now
woo yeah, I see them a lot in the wild. I mean really the only time I really see frames used anymore are iframes and generally in eCommerce and similar security requiring solutions where the frame can be partially controlled by the storefront, but is more fully controlled by the payment provider. I just find the statement "framesets are here to stay now" really weird and triumphal for something that is so rarely used?
>I still have one of the funnier "how to make this without tables?" challenges.
I followed the link, I would think it is better suited to a "why would you make this" challenge. I'm not sure
1. it shouldn't be a table. seems like maybe it should be
2. why the freaky animation. or for that matter why the animation nearly crashed my browser.
I'm definitely sure lots of designs could not be adequately achieved without tables and framesets, but my experience seems to have run contrary to yours because for me CSS was a godsend in fixing the things I found irritating about those two technologies, this does not mean that I never encountered situations where I thought this would be easier with tables, but as soon as I tried putting tables back in I found all those irritants came back in.
From my experience tables and framesets were best suited to layouts that are rarely ever wanted, and when used to implement slightly different layouts had too many problems and irritants to be useful.
Your mileage has obviously differed, but I'm not sure that "here is a particular problem that people seldom wish to solve and which I have constructed, that plays to the strengths of my favored technology while avoiding its pitfalls" is as impressive an argument as you seem to think it is.
I think it's fairly easy to understand if you understand what it was a backlash against. Tables today are used sensibly, for the most part, but the pre-CSS world was truly absurd in its table use.
The reaction may well have been over-the-top, but it wasn't disproportionate given the state of table usage at the time.
CSS's initial forays into layout seem bad today because people think of tables in terms of their intended use (not the now long-gone monstrosities the community actually extracted from them), but in comparison to the previous ecosystem, floats were a relative godsend.
Tables as a layout primitive are fine. Lots of modern layout engines are based around vstacks and hstacks, which are just single table rows and columns. Most paper forms use a 2d table layout, and newspapers arrange their articles in a 2d table layout.
There were some reasonable concerns. Using tables for both layout and literal tables removes semantic meaning, nested tables can get complicated to layout, and layout the whole page as a giant table makes it difficult to adapt to screen size. But the first could easily be solved by adding a tag that works exactly like table but is for layout, the other two are about overuse of tables in the absence of viable options. We could have easily kept table layouts for the parts where it makes sense and augmented it with something css-like for the parts where it doesn't.
This is somehow worse than "never use goto"; because there are plenty of good uses for tables, and CSS was lacking features for forever after the clowns declared "tables bad" and the other clowns followed without thinking
The killer argument at the time (and even now most likely) is that screen readers could not distinguish whether the table was used for layout or for data and therefore sight-impaired users would have trouble.
The argument doesn't make sense because it is not too hard for a screenreader to understand whether a table is used for layout and even if it was hard the problem would more easily be solved by just adding an attribute to the table to indicate that it is used for layout.
Tables aren’t dead, they never were… when displaying tabular data. When it comes to layout I think you might be wearing rose tinted glasses. Remember having to put a 1px image in a table cell to avoid it disappearing? Remember “best viewed at 800x600”? I’m personally not nostalgic for either.
For what it’s worth, the very page we’re on here still uses tables and spacer gifs, in 2025. (EDIT: I don’t mean to imply that this is good, just an inescapable observation in this context)
Today it's usually implicitly designed for iphone, designed for 1080p, or ipad, and you have to guess, strong correlation with whatever device the designer uses in his personal life.
sidenote: as a teen, i would regularly layout posters and presentations in excel.. the page preview dashed-border and the grid stability was such a relief compared to word
On commodore 64 the screen is just a fixed size grid of characters. No one ever had issues making an ui. We pretend but flexible viewport size is not actually possible. If you are making a painting for example the size of the canvas greatly influences what can and can be done.
I made a stunning landscape photo one time that looked great only when displayed at roughly the size of a hand. If made larger undesirable details became visible (littering), when smaller important details were lost (a formation of birds over a fishing vessel).
> The display property should be called display-type.
More importantly to me, "display" has been overloaded with two meanings: Display of the element this rule applies to/how it interacts with surrounding elements (none, block, inline, inline-block) and display of the contents of this element (flex, grid).
Which is why we now also have inline-flex and inline-grid.
Default heading styles should not have equal top and bottom margin. Headings should be closer to the content they label than to the content they are setting their content apart from.
h1, h2, h3 should not have different styles. it's an anti-pattern that leads to broken accessibility
moreover h* is just broken whenever dealing with more dynamic content — it simply can’t reasonably be made to work according to accessibility recommendations — and the accessibility guidelines around never skipping a level themselves are ridiculous given the practical reality that dynamic content exists and we have only h1, h2, etc. to work with — the readers and specs are what need to adapt here, not the entire internet
there should really be one header tag and its level should be based on some nesting depth
and don’t get me started on the maintainability mess that is z-index… better we have a system to centrally maintain an ordering list than a distributed one which only works reasonably consistently if you already know everything in the whole system
I like how z-index works, currently. And though I agree with the article, it should apply to all elements by default, I'm not sure how you'd do stacking differently in a way that'd work any better than the current situation?
You can't do away with stacking contexts, you need those to isolate content you don't control to prevent it from breaking the stacking order of content you do control.
I completely agree with you about h* tags, though. I wish html5 sectioning hadn't been killed by the browser vendors. As is there's no safe way to put headings inside custom elements. We almost had it, it was specified and everything.
The problem with trying determine heading depth automatically is the depth is not something that can be deduced just by the structure. If headings are siblings, for example, the may be on the same level semantically or not.
One way I've dealt with this in react is combine a Heading component with ContentGroup component. Each content group needs exactly one heading, and heading can't exist without it. Content group can contain other content groups. The tag for heading can then be determined by how many content groups are in the tree above it.
This works pretty well ime, but it can be hard to get devs to use (or think about accessibility at all).
That's sensible, but I think default styles for specific elements are not part of the CSS standard, and are instead dictated by the user-agent stylesheet of your browser.
> h1, h2, h3 should not have different styles. it's an anti-pattern that leads to broken accessibility
How does that hurt accessibility? Are you saying people use h3 in order to get its style even when they didn't mean h3?
I think the opposite could happen too - if they all have the same style then people might just use h1 everywhere which is probably just as bad. People tend not to use elements that have no obvious use, like <output> which apparently has better accessibility but does absolutely nothing else, so nobody bothers. The whole "semantic web" thing failed partly because of this.
This felt relieving. As in: some part of me had felt stupid for thinking some of this seems really unintuitive when using it in practice. Like z-index stuff, margins, vertical-align, border-radius, ...
Meanwhile, one of the linked pages mentioned bluegriffon, so I got curious if such editors can handle template languages such as django's.
While I don't know that yet (edit:no templates at all, what a shame), I also found this tutorial, and it was inspiring that such a pedagogical approach to online authoring still exists.
Edit: no seriously, why don't these editors support at least some established template language? I think dreamweaver had a concept of templates, which made using these editors make at least some sense.
Edit: oh wow dreamweaver still exists. Any of you have experience? Still good?
It is extremely funny to me that the list thinks the mistake about !important was using the exclamation mark sigil, and not the concept of a single priority level.
In the words of one of my CS profs, from a few decades ago: "There are only 3 numbers - zero, one, and infinity. And 'one' is often a mistake"
As opposed to the 15 levels of priority available in Chef.
5 different types (default, force_default, normal, override, force_override)
which can be in 4 different places (attribute, node, environment, role) but not all of the types can be in all of the places
PLUS the "automatic" type, which is from somewhere else entirely
Oh and there's inheritance and merging which does not behave intuitively at all because it's not exactly inheritance.
In other words I have early career trauma from someone's extremely unwise priority implementation and am deeply suspicious of ANY priority override system which isn't just code I've written in a normal programming language.
A lingering bit of weirdness is that all !important declarations, no matter the layer they appear on, are interpreted as being part of their own implicit layer.
There is no need for more priority levels, because precedence is already defined by
inline > #ID > .class / [attribute=""] / :pseudo-classes / elements / ::pseudo-element / universal selector (*). And the order they're written, if both have the same priority. The !important just exists to override that order.
When I occasionally venture I to standards-land, I always ask "what user research have you done on this?"
So many weird design choices in computing are because one person said "this seems right to me" without considering other viewpoints or consulting with the wider community.
Sure, you probably dont want death by committee, but a tiny cabal engaging in groupthink often produces unhelpful results.
Many of these mistakes weren't even made by any committee, but were stuff shipped in a rush by Netscape or Microsoft to win the browser wars.
There was some (academic) reaserch behind early CSS concept, but the original vision for it didn't pan out ("cascading" was meant to blend style preferences of users, browsers and page authors, but all we got is selector specificity footguns).
Netscape was planning to release their own imperative styling language, and ended up shipping a buggy CSS hackjob instead.
Once IE was dominant, Microsoft didn't think they have to listen to anybody, so for a while W3C was writing CSS specs that nobody implemented. It's hard to do user research when nothing works and 90% of CSS devs' work is fighting browser bugs.
This feels like the origin of a lot of these mistakes (and more besides): they weren't based on "what is it that lots of real designers are actually trying to accomplish?". Why did it take so long to get support for pinstriping, when prior to that there were 1001 different ways to try and accomplish it, because so many people wanted it? Why did it take so long to get layout functionality that even just matched the power of what CSS was intending to replace? Or vertical alignment, or drop shadows, etc, etc, etc. I like CSS and the intentions of it, but man, it was designed from a place of having no idea what people wanted to do.
This is true, but my feeling is that with CSS, a lot of the weird decisions are for backwards compatibility with way back when HTML was just tag soup and browser implementations were haphazard.
I don't understand the point about comments. Why shouldn't they be allowed? What object model?
>Comments shouldn't have been allowed basically everywhere in CSS (compare to HTML, which basically only allows them where content goes), because it makes them basically unrepresentable in the object model, which in turn makes building editing directly on top of the object model impossible
Imagine you have something like `width /comment/: /comment2 /12px /comment3/,`. Now you want to load your css into some kind of structured representation, rearrange it, then spit it back out again with that comment intact. The requirement to represent such comments in your structured format so you can retain them is really obnoxious. In html you can just view comments as another node in a uniform tree.
> In html you can just view comments as another node in a uniform tree.
When you parse an AST with comments (or a CST), they do become "just another node in a uniform tree". Think about it - in HTML you have a tree of nodes but comments can be anywhere, which is exactly as obnoxious to deal with as a CST where comment nodes can be anywhere.
This is a terrible reason to not support comments. If it was really important, then probably you should support comments in only a couple of places, e.g. on attributes or on selectors.
But I don't think it is very important. I can't think of a single tool that loads CSS, rearranges it, and then spits it back out in a form that would benefit from comments.
I'm guessing they mean that comments shouldn't be allowed everywhere, not that they shouldn't be allowed at all? i.e. CSS lets you put comments in many more places than HTML, in such a way that it's hard to practically impossible to represent in an AST? At least that's how I read it
Same reason why JSON prohibits comments: When you parse it, there is no place to represent the comments in the JavaScript object and array tree, so they must be thrown away, therefore it's impossible to write it out with the same comments in the same places.
Same thing with white space: JSON can not round trip white space or comments the way XML or HTML can, because XML and HTML DOM represents comments and white space explicitly.
Also you can't put comments inside elements like <div <--! comment --> class="foo">. There is no way to represent a comment inside an element in XML or HTML DOM.
But CSS lets you, so you can't round trip comments in CSS.
HTML comments are basically just a HTML tag that isn't rendered. Tools that 'compile' the HTML code into a document tree, including browsers, preserve comments as nodes without any extra effort.
CSS comments can go anywhere:
/*wow*/ .selector /*x*/ {animation /*z*/: 2s /*z*/ linear /*z*/ bounce;}
Tools that transform/parse CSS can either:
1. Strip comments before parsing, meaning anything based on the parsed version will lose the comments.
2. Dedicate a disproportionate amount of complexity to retaining the comments, and still not really have a good way to handle them through edits/transformations.
But if it's valid CSS it has to be representable in AST/object model? It's a comment, it can't have any child nodes, it doesn't depend on anything - pretty trivial. And if it's in the tree you can transform it with proper tools. If you are transforming CSS you have to write a proper parser and not just a bunch of regexes
EDIT: also why is it useful to have comments in the object model in the first place? To access them from js?
The greatest mistake IMO is the way float state leaks out of blocks, as this
is both extremely unintuitive and undesirable for performance reasons.[1]
Floats should've been restricted to inline formatting contexts, with all
in-flow blocks behaving as if they had `clear: both' set.
I also don't understand why they never specced the (much simpler)
`text-align: -moz-left/-moz-right/-moz-center' which already had precedent
in HTML with `<div align=left/right/center>'. It's the saddest part of the
"center a div" saga, all the W3C had to do to fix it is to assign a standard
keyword to a feature that everybody already implemented, but to this day
it still hasn't happened.[2]
[2]: After many long decades, they did finally specify block-level
`justify-items'. Two problems: a) it's backwards-incompatible with
text-align, b) it still doesn't work in Gecko.
