CCS is worst language ever created
-
I'm not talking about clever ways to generate complex CSS, I'm talking about expressing relationships between page elements that is not possible at all with current CSS. For example: "The height of element B is 1/10th of what ever the page height is at the moment. The width of element A should be equal to the height of element B, but only if B's height is less than 100px, in other case it should be half of the height of element B.". Here is how simple it could look in theory: B.height = PAGE.height / 10; A.width = B.height < 100px? B.height : B.height / 2;

The reason stuff like that isn't possible is because you will get endless recursion. Let's say you have:
The height of B is determined by the content of A, but if you are changing the width of A based on the height of B then the height of A will also change, which in turn forces the height of B to change, which would then require the width of A to change, which will once again change the height of B, and the loop continues until you get a StackOverflow exception. So perhaps you say: "Well, don't allow rules like that", but then you end up with even more of a headache trying to make sure your rules don't conflict with other rules. Put it this way, if it was possible to make it work well then it would for sure already exist. As the saying goes: if you have a good idea, it either already exists or it really isn't that good an idea.

No language has casued me more grief in my 30+ year career than CSS. It is almost like some form of black magic, where you can never be 100% sure what a page will look like. Even for the simplest designs you have to allocate 4 hours, just to make sure it looks the same in all browsers. Why the decision to write an enormously complex layout engine, and then keep adding more bloat to it every year? Why not let the page designer interact with the layout engine instead, as it is laying out the elements on the page? It could be done through JS calls, or even by writing simple math formulas into the CSS, that refer to the sizes of other elements. For example "the width of this element should be equal to half the width of that element". Then let the browser's layout engine simply be a multi variable equation solver. End of rant.

It's a language by committee. And a committee made up of teams that are actively competing with each other. Read this discussion on CSS4[^]. They actually, deliberately, don't want to increment the CSS version anymore. That's like macOS stopping at version 10 (...but instead is 10.1, 10.2 etc), and Windows 10 stopping at 10. Or 10 20H1, 20H2...) I think the hardest part of CSS is the "C" - the cascading, which relies on Specificity. It's super logical and very well defined. And an utter nightmare as soon as you step off the beaten track. Switch elements around, decide you need some special formatting, try and generalise it, and boom! Still - it does at least attempt to encourage a separation of layout and style. Except the CSS defines the layout :doh:

Indeed, most people don't even think at all... But I don't particularly agree that we only advance from unique ideas. I am sure a lot of people come up with the same ideas all the time, it's just who gets to market first, so to speak.

What you describe already happens in the layout engine of modern browsers. The rules that I outlined earlier already happen, but is invisible to us. There are hundreds of such rules that must be evaluated to produce the final layout, and some are in direct conflict with each other, so the engine is designed to make a compromise. These compromise heuristics is what avoids endless recursion. So imagine that tomorrow the Google Chrome team launches a new module called JSCSS, were they have moved out all those heuristics from inside the layout engine and written them in JS. From now on you point to a JSCSS file at the beginning of a HTML page, which defines all the CSS rules you intend to use. CSS still works exactly like before. But the HUGE difference is, now you can see how a flexbox actually figures out layout, AND you can extend CSS with your own definitions for things you think is better than the standard. AND you can omit CSS altogether, and write your layout directly in JSCSS of you want. This would be a huge relief for everyone, because browser makers only have to make sure the core layout engine works correctly, and every CSS definition is in external JS, exactly the same for every browser. And any developer can extend CSS with his own definitions.

Yea I wish CSS was only about style, and layout was handled in a different way. I think it is possible to keep the core layout engine of the current browsers, and create a kind of scripting language they can run, so the developer can interact with the layout procedure. These ideas have been proposed before, so I can't understand why we still have CSS today. I was cursing HTML layout 15 years ago, and couldn't imagine we would still be doing things the same way today. Some developments in this space have been amazing, but HTML/CSS/JS has really been a disappointment. There is still not a practical way to write C# and run it in the browser, just promises of WASM and compilers that never hit mainstream.

Thanks for the link, interesting read. If PSL96 had been implemented instead, CSS would be a lot easier. You simply express sizes of things in terms of sizes of other things. It would have resulted in a much smaller language, that most people could grasp. And people would create libraries of handy expressions that accomplish the very same things that flex and grid does today. With the huge difference that you can look at the code and see what happens. Right now it is just a back box that almost no one understands. Browser support would be easier and more uniform, not harder, because there is a smaller feature set to implement. Do you know of any other language where there is so low predictability of outcome? You basically spend your time trying 100 different tweaks until it looks right.

That might work for basic stuff. Once you want to use different styles for different screen sizes, this becomes unworkable very quickly.

They have started to add programmatic elements to it and it won't be long before there will be a full blown css scripting language based on COBOL - because for reasons that are unclear to me the entire community is committed to making things as complex/multi-layered/obtuse as possible. Whatever you do on a webpage you must never just put an input element on the form - it must have a template that references other templates and style sheets that must be run through SASS and dozens of other utilities/mods/nightmares - all to collect a first and last name from a customer. I swear to Judas that some developers go into a project seeking to add as much complexity as possible.

Haters are going to hate. I don't know much JavaScript, never worked in it. But I have made a very nice living/career over the last 43 years with VB. :) All languages are just syntax. VB is a tool just like any other. If you misuse an axe bad things are going to happen to you. I am sorry to learn that someone who does "Thought for the Day" could be such an elitist.
