Sometimes, after wrapping a list of widgets inside a Column or a ListView, the widget takes the whole width or height of this column. However, I simply wish it took the height or width of its contents, but so far I've only been able to find either very complicated ways of doing this or ways of giving, for example, buttons and texts fixed width or height.
In CSS, there's min-content and max-content for doing this sort of stuff. Is there an equivalent in Flutter?
Look at the Flexible widget. Unlike Expanded, it tells the widgets to take up as much space as they need. They can fill the whole space if they need to, but otherwise they only take up the space their contents do.
See also this comparison of Flexible and Expanded: Flutter: Expanded vs Flexible.
Partial answer here: sometimes, putting the stretched widget inside a Row or a Column can work. And there are also some specific widgets for this, e.g. ConstrainedBox.

I'm looking at creating a grid for a day view of a calendar, where the items are vertically positioned and sized according to their start and end times. If an agenda item doesn't overlap with anything else, its width will span the full width of the column; however, if items overlap, they split the width between them. Example images below:
Full-width items, no overlap
Overlapping items
Clearly, this can all be calculated using Javascript with full knowledge of all the meetings at once. However, I'm wondering if there's an elegant CSS solution to handle this, where the code needs to only provide the vertical position and height?
I ask because I'm hoping to organize my React code such that each grid box only needs to know the data for its own agenda item, keeping good encapsulation; rather than needing to pass in a bunch of data (pre-processed or not) about other items.
This sounds like a perfect use case for flexbox. Which also plays nicely with React.
Bootstrap V4 can be used with flexbox. Another good option if you are using PostCSS is lost grid.
I have this ui-grid containing a random number of rows, but sure thing, it contains a great number of columns.
That said, I have a someway responsive-related problem: I want the grid to fill the remaining space of the page, in both width and height.
Apart from look-and-feel reasoning, the logic behind this is, on large screen devices, to allow the user to look at as much columns as possible and to extend the ui-grid height to the bottom, even if there are few rows displayed (btw, the page has no footer).
So, using a media query, I set width: 100% to the grid and manage to do the first part of the trick, but I'm struggling for the second part: the height.
I can't really make the gridWrapper height to expand the grid to the bottom, even if his width behaves correctly, without using Bootstrap but... the css struggle is real.
So I managed to have something near to what I want, but:
it's a ridicoulusly complicated, weak and un-reusable solution;
the row selection icon layout (the one on the left side of the rows) messes up as the row number grows, and i can't get rid of the selection feature by now;
the height of the grid is greater than the height of the page. I could set it to 90% instead of 100% to make it work... close, but not responsive, still.
Even if this scenario is the subject of many issues on the GitHub of the project, I'm asking you:
Is there a way to obtain what I want in a responsive, maybe bootstrap-inclusive way before I delve in a swamp made of display: table;, display: flex; & Co.?
give grid height: auto either in css or once grid is ready i mean once you have assigned array to gridOptions.data after that
$(".ui-grid").css("height", "auto");
I am affraid that only way how to achieve this is use of JS and setting css height and width programatically.
You have to set it when:
grid is created
window size changes
I have never heard of this intrinsic value before until I come across this page on MDN.
From what I know intrinsic means natural. So how does this work out in CSS. I thought that auto would have been natural. I've searched around a bit but can't find anything on it.
What does it do different than auto?
The example I saw was max-width: intrinsic;
It looks like the intrinsic value is part of the newer CSS3 sizing module:
http://dev.w3.org/csswg/css-sizing/
I have not used it yet but perhaps the reference will provide you with more information.
Based on a quick review, this module would make it easier to specify how content fills the width and height of a parent containing block.
At the moment, JavaScript functions are often used to compute widths and heights of container blocks based on % values for variable child elements content.
It allows you to set the width of an element to stretch wide enough to accommodate its children. So, if a div element contained a wide image and some text, the div would stretch wide enough to accommodate the image, and the text would begin breaking at that threshold.
Definitely experimental and not widely supported: http://caniuse.com/intrinsic-width
Intrinsic sizing determines sizes based on the contents of an element,
without regard for its context.

I have found that in iOS8, flexbox children may not always try to contain all their children and instead max their height to the available viewport.
min-height: min-intrinsic fixes that problem.
I am trying to do something similar to float:left. For float:left, if you set a bunch of divs with this style property, it will position itself according to the width of window. When the window gets too narrow, it will become one column, and when we have large window, it will expand to multiple columns and so forth.
I want to do something similar but I want it to work like a vertical float. So if I have 5 items and the browser's window height can only contain 4 in one column, the extra div should position itself to the 2nd column. In simple terms, if I have a long list of divs, they should be listed in columns depending on the height of window.
Is there a way to do this with div and css or jquery ui?
This isn't possible with CSS alone. Your best bet is something like masonry:

(or for snazzy filtering and stuffs isotope, which is powered by masonry: http://isotope.metafizzy.co/)
Hope that helps :)
Now this is a tricky question, with the concern of not using tables or JavaScript for this task.
Basically I have a five columned row, one column takes any type of content that can extend the height, but the task is to make the sibling columns take up the same height as that column with fluid content.
Demo: http://jsfiddle.net/Mrg5E/
As you can see in the second row, it has bigger content inside it that takes up the height, but this breaks the siblings height too.
I've looked around proposed answers, mainly using tables or JavaScript - this is something I need to avoid this. I've also looked at hacks such as the Holy Grail, etc, but this is mainly for 2-3 columns when I have 5 columns (sometimes 4).
Is there a possible fix in CSS to match all the siblings heights?
If you have no idea what the one column with variable content's height will be, then no, you can't do this with CSS alone. You will need to either fake it, or use javascript.
If you have a fixed width layout, you could try the faux column technique. That's "faking it" with a background image that tiles vertically, giving the illusion that the columns are the same height. The example in the article uses two columns, but there is no reason you can't use it for five.
The other way is using javascript. If you are using jquery, there is a plugin that can help you out. The basic idea is to identify the greatest column height, then apply that height to the other columns.
Use the min-height property and for cross browser solution, take a look at:
