“float” and “normal” (what?) aren’t layout modes. the rest didn’t exist in css until relatively recently. postion: relative exists, yes, but it doesn’t do what you say it does. - it sets the top, left, bottom and right properties to be relative its own natural position. it doesn’t specify any relationship to any other element. the other properties you say specify layout relative other elements- don’t do what you think they do either. align and margin only effects an element’s content, margin only refers to other elements in edge cases, and float was only ever supposed to let you embed figures that text would wraparound. it’s use for layout was an abuse and not what it was designed for. Though i can see how it can seem like those elements seem like they refer to other elements, but that is just a consequence of the properties interacting with the document flow algorithm, which is there with or without css. while css now does have real layout modules: flexbox and grid, CSS wasn’t designed for layout and it just isn’t very good at it, especially if you compare it to say, cocoa autolayout, or the flexbox model in UI frameworks that were designed to do this stuff at the start instesd of having it awkwardly bolted on. and just what is document flow? is it a layout algorithm? no, it’s a greedy word wrap algorithm applied to boxes. that’s it. finally, 15 year old display: table and flex hacks? what are you smoking. ie8 was released in 2009 and didn’t uproot ie6 and ie7 until many years later. i had to have fallbacks for ie7 up to 2015. flex only became usable after 2015. it existed before that but not in all the browsers. the closest thing in css to what I am talking about is position:absolute, which implicitly refers an element to its nearest parent with either position relative or position absolute. i don’t get to identify which element or elements i would like to refer to directly. the only other thing is percentage unit which refers to a percentage of the paren’s width or height depending on which property it appears in- which was annoying enough they almost fixed it with vw and vh units which refer specifically to width and height of the viewport, but if i want a proportion of any other element’s dinensions my option is to use javascript or eat a bag of donkeys. |

> the rest didn’t exist in css until relatively recently.
Out of the 7 layout modes, only the last two came into existence recently. The point is, when CSS was being designed as a declarative, domain specific programming language, it was designed to handle EVERYTHING to do with how things appear on a browser. Even when you specify styles using JS or directly in HTML, those are simple handed over to the browsers CSS engine. The HTML engine deals with markup, while the JS engine deals with behavior. If you want to talk directly and powerfully to the CSS engine, use CSS. That what it was designed to handle: everything to do with what you SEE in a browsers screen.
> position: relative exists, yes, but it doesn’t do what you say it does. - it sets the top, left, bottom and right properties to be relative its own natural position.
If I want to position elements absolutely within a container element, one way is to have the container "position: relative" and the child elements "position: absolute". The same effect can be achieved via flex or grid layouts.
> it’s use for layout was an abuse and not what it was designed for.
I am honestly flabbergasted by this assertion. The layout of something is part of its style. See https://en.wikipedia.org/wiki/Visual_design_elements_and_pri... CSS was designed to handle all that. Layout is all about shape, space and form.
> CSS wasn’t designed for layout and it just isn’t very good at it, especially if you compare it to say, cocoa autolayout, or the flexbox model in UI frameworks that were designed to do this stuff at the start instead of having it awkwardly bolted on.
Whenever anyone dumps on CSS, HTML and JS, I simply remind them that they run the web, and the web is the most successful, open, flexible and used platform in existence. CSS is doing exactly what it was designed to do, and will outlive and outperform all those UI frameworks as it breaks out of the browser into desktop and mobile app space.
