I suggest running the code snippet below to better understand this question, as it is a layout question, and visually easier to understand.
I have an element on my page that needs to display one item (a Title) aligned to the left, and another item (Date/Time) aligned to the right, in the same "row". I accomplished this easily using CSS Grid.
My designer told me that when we display on a mobile device, it should instead show the Title left-aligned, and the Date/Time below that on the next line, ALSO left-aligned. CSS Flex does this with grace.
Is there a way to make either CSS Grid or CSS Flex do both of these things, without jumping through hoops?
What I'm trying to avoid is having to write a slew of #media breakpoints, and just handle it organically instead, if possible.
Thanks for any advice you can offer.
.container {
display: grid;
grid-template-columns: 1fr 1fr;
font-weight: bold;
}
.date {
justify-self: end;
}
.flex-container {
display: flex;
flex-direction: column;
font-weight: bold;
}
When on a wide device screen (e.g. Desktop Web Browser) I want the layout to look like this. The title should be on the left and left aligned, the date/time should be on the right and right aligned. The should adjust with the page width.
<p>
<div class="container">
<div>Some Title</div>
<div class="date">01/26/2021 10:30am</div>
</div>
</p>
However, when on a small device screen (e.g. smart phone) the Title should appear on one line, left aligned, and the Date/Time should appear below it, also left aligned.
<p>
<div class="flex-container">
<div>Some Title</div>
<div class="date">01/26/2021 10:30am</div>
</div>
</p>
Is there a way to accomplish this easily, hopefully using CSS Grid or Flex, rather than hard coding CSS changed to breakpoints?
Flexbox is really all you need.
.container {
display: flex;
justify-content: space-between;
flex-wrap: wrap;
}
<div class="container">
<div>Some Title</div>
<div class="date">01/26/2021 10:30am</div>
</div>
Is there a top-level container that applies the styles you get with mat-toolbar or mat-card? This answer seems to recommend using mat-card, but that seems weird to put the main body of an app in a mat-card and also it comes along with some other baggage (eg, border-radius that would need to be unset). I could make a mixin to emulate the styles I see in the dev tools:
#mixin toolbar-like() {
display: flex;
box-sizing: border-box;
padding: 0 16px;
width: 100%;
flex-direction: row;
align-items: center;
white-space: nowrap;
}
but this seems unidiomatic, and I'm not sure if the CSS changes at different viewport sizes that I need to account for, so that is hacky. In the end I am only talking about a few lines of CSS, but it seems odd I cannot a standard way within the framework to accomplish this.
What is the Material-Way to contain a body content so that it displays naturally alongside other material elements?
Not sure if I understand your question correctly, if you want to apply styling to your component itself without wrapping it in a container you can use :host
Consider using regular 'div' tags with #angular/flex-layout.
StackBlitz here:
https://stackblitz.com/edit/angular-material-flex-layout-seed?file=app%2Fapp.module.ts
<div fxLayout="row" fxLayoutAlign="space-around center">
<!-- items to layout horizontally -->
<div>...</div>
<mat-card>...</mat-card>
etc...
</div>
This might not be possible to do strictly with flexbox or it may require some media queries. I'm fine with that. I'm wondering if there is a way to have four items arranged horizontally in one row that will responsively switch to two columns both with two items.
I've tried various things to do this such as:
.flex-container {
display: flex;
flex-flow: row wrap;
justify-content: center;
}
button {
width: 250px;
}
<div class="flex-container">
<button>a</button>
<button>b</button>
<button>c</button>
<button>d</button>
</div>
This works okay, but if you reduce the screen width it wraps to three items in the first row and one item in the second until you reduce the width to less than the width of the three items. If the screen width gets too small to have all four items arranged horizontally, I'd like it to be two columns and two rows of items.
I have some control over the width of each item in the row, but they will be relatively small like buttons (maybe 200px max).
Is this possible to do with flexbox? If not, is there a better alternative to wrapping to an appropriate grid?
One idea without media query is to use extra wrapper for the button like below:
.flex-container,
.flex-container > div{
display: flex;
flex-flow: row wrap;
justify-content: center;
}
button {
width: 250px;
}
<div class="flex-container">
<div>
<button>a</button>
<button>b</button>
</div>
<div>
<button>c</button>
<button>d</button>
</div>
</div>
If the width of each button is to stay fixed, you can simply set the max-width of the container to that width, times the (maximum) number of buttons you want on each row.
See this codepen.
I am trying to vertically align elements within an ID wrapper. I gave the property display:inline-flex; to this ID as the ID wrapper is the flex container.
But there is no difference in presentation. I expected that everything in the wrapper ID would be displayed inline. Why isn't it?
#wrapper {
display: inline-flex;
/*no difference to display:flex; */
}
<body>
<div id="wrapper">
<header>header</header>
<nav>nav</nav>
<aside>aside</aside>
<main>main</main>
<footer>footer</footer>
</div>
</body>
display: inline-flex does not make flex items display inline. It makes the flex container display inline. That is the only difference between display: inline-flex and display: flex. A similar comparison can be made between display: inline-block and display: block, and pretty much any other display type that has an inline counterpart.1
There is absolutely no difference in the effect on flex items; flex layout is identical whether the flex container is block-level or inline-level. In particular, the flex items themselves always behave like block-level boxes (although they do have some properties of inline-blocks). You cannot display flex items inline; otherwise you don't actually have a flex layout.
It is not clear what exactly you mean by "vertically align" or why exactly you want to display the contents inline, but I suspect that flexbox is not the right tool for whatever you are trying to accomplish. Chances are what you're looking for is just plain old inline layout (display: inline and/or display: inline-block), for which flexbox is not a replacement; flexbox is not the universal layout solution that everyone claims it is (I'm stating this because the misconception is probably why you're considering flexbox in the first place).
1 The differences between block layout and inline layout are outside the scope of this question, but the one that stands out the most is auto width: block-level boxes stretch horizontally to fill their containing block, whereas inline-level boxes shrink to fit their contents. In fact, it is for this reason alone you will almost never use display: inline-flex unless you have a very good reason to display your flex container inline.
OK, I know at first might be a bit confusing, but display is talking about the parent element, so means when we say: display: flex;, it's about the element and when we say display:inline-flex;, is also making the element itself inline...
It's like make a div inline or block, run the snippet below and you can see how display flex breaks down to next line:
.inline-flex {
display: inline-flex;
}
.flex {
display: flex;
}
p {
color: red;
}
<body>
<p>Display Inline Flex</p>
<div class="inline-flex">
<header>header</header>
<nav>nav</nav>
<aside>aside</aside>
<main>main</main>
<footer>footer</footer>
</div>
<div class="inline-flex">
<header>header</header>
<nav>nav</nav>
<aside>aside</aside>
<main>main</main>
<footer>footer</footer>
</div>
<p>Display Flex</p>
<div class="flex">
<header>header</header>
<nav>nav</nav>
<aside>aside</aside>
<main>main</main>
<footer>footer</footer>
</div>
<div class="flex">
<header>header</header>
<nav>nav</nav>
<aside>aside</aside>
<main>main</main>
<footer>footer</footer>
</div>
</body>
Also quickly create the image below to show the difference at a glance:
flex and inline-flex both apply flex layout to children of the container. Container with display:flex behaves like a block-level element itself, while display:inline-flex makes the container behaves like an inline element.
Using two-value display syntax instead, for clarity
The display CSS property in fact sets two things at once: the outer display type, and the inner display type. The outer display type affects how the element (which acts as a container) is displayed in its context. The inner display type affects how the children of the element (or the children of the container) are laid out.
If you use the two-value display syntax, which is only supported in some browsers like Firefox, the difference between the two is much more obvious:
display: block is equivalent to display: block flow
display: inline is equivalent to display: inline flow
display: flex is equivalent to display: block flex
display: inline-flex is equivalent to display: inline flex
display: grid is equivalent to display: block grid
display: inline-grid is equivalent to display: inline grid
Outer display type: block or inline:
An element with the outer display type of block will take up the whole width available to it, like <div> does. An element with the outer display type of inline will only take up the width that it needs, with wrapping, like <span> does.
Inner display type: flow, flex or grid:
The inner display type flow is the default inner display type when flex or grid is not specified. It is the way of laying out children elements that we are used to in a <p> for instance. flex and grid are new ways of laying out children that each deserve their own post.
Conclusion:
The difference between display: flex and display: inline-flex is the outer display type, the first's outer display type is block, and the second's outer display type is inline. Both of them have the inner display type of flex.

The Difference between "flex" and "inline-flex"
Short answer:
One is inline and the other basically responds like a block element(but has some of it's own differences).
Longer answer:
Inline-Flex - The inline version of flex allows the element, and it's children, to have flex properties while still remaining in the regular flow of the document/webpage. Basically, you can place two inline flex containers in the same row, if the widths were small enough, without any excess styling to allow them to exist in the same row. This is pretty similar to "inline-block."
Flex - The container and it's children have flex properties but the container reserves the row, as it is taken out of the normal flow of the document. It responds like a block element, in terms of document flow. Two flexbox containers could not exist on the same row without excess styling.
The problem you may be having
Due to the elements you listed in your example, though I am guessing, I think you want to use flex to display the elements listed in an even row-by-row fashion but continue to see the elements side-by-side.
The reason you are likely having issues is because flex and inline-flex have the default "flex-direction" property set to "row." This will display the children side-by side. Changing this property to "column" will allow your elements to stack and reserve space(width) equal to the width of its parent.
Below are some examples to show how flex vs inline-flex works and also a quick demo of how inline vs block elements work...

Also, a great reference doc:
A Complete Guide to Flexbox - css tricks
Display:flex apply flex layout to the flex items or children of the container only. So, the container itself stays a block level element and thus takes up the entire width of the screen.
This causes every flex container to move to a new line on the screen.
Display:inline-flex apply flex layout to the flex items or children as well as to the container itself. As a result the container behaves as an inline flex element just like the children do and thus takes up the width required by its items/children only and not the entire width of the screen.
This causes two or more flex containers one after another, displayed as inline-flex, align themselves side by side on the screen until the whole width of the screen is taken.
I'd like to add some details about screen reader behaviour, because there's some surprises here.
Some background first. Some screen readers like NVDA handle display: block and display: inline-block differently (and they should, as you will see later).
Comparison between different display attributes
display: block
A display: block element will always be announced in a separate "line", meaning NVDA will stop talking after its contents, and the user will manually tell NVDA to announce the next element (typically with Down arrow key).
<div>This is the first line</div>
<div>This is another line</div>
This will make NVDA announce This is the first line, and then This is another line.
The following yields the same result:
<span style="display: block">This is the first line</span>
<span style="display: block">This is another line</span>
display: inline-block
A display: inline-block element will be announced together with all preceding and following other inline elements (display: inline and display: inline-block).
<span style="display: inline-block">This is the first line</span>
<span style="display: inline-block">This is another line</span>
This will make the screen reader announce both elements in one go: This is the first line This is another line.
As said before, it doesn't matter whether it's an inline or inline-block element; the following yields the exact same result:
<span style="display: inline">This is the first line</span> <!-- Inline! -->
<span style="display: inline-block">This is another line</span> <!-- Inline block! -->
display: flex
This works exactly like display: block.
display: inline-flex
Surprisingly, this also works like display: block, not like display: inline-block!
display: grid / display: inline-grid
I didn't test this, but I expect the same like with flex / inline-flex here.
Why is that a problem?
Using display: inline-block, one can create elements that visually look very distinct, but semantically are treated "as one".
For example, consider the following headline in an online news platform:
<h2>
<span class="category">Rain forests</span>
They need our love
</h2>
You now want to visually style the category (Rain forests) very different to the "real" title ('They need our love'), i.e. by putting each in its own line, something like this:
If you'd make category a display: block element, then the screen reader would announce the heading in two separate lines like this: Rain forests, heading level 2, then They need our love, heading level 2. This is confusing to the user: are there two different headings on the page? Why is there no content for the first one (instead, immediately an apparent second heading seems to follow)?
If however you'd make category a display: inline-block element, then the screen reader would announce the heading in one go: Rain forests They need our love, heading level 2.
It is sad, that display: inline-flex (and probably inline-grid, too) does not mimic the behaviour. So if you want to offer perfect accessibility, you might want to use inline-block in such situations.
You can display flex items inline, providing your assumption is based on wanting flexible inline items in the 1st place. Using flex implies a flexible block level element.
The simplest approach is to use a flex container with its children set to a flex property. In terms of code this looks like this:
.parent{
display: inline-flex;
}
.children{
flex: 1;
}
flex: 1 denotes a ratio, similar to percentages of a element's width.
Check these two links in order to see simple live Flexbox examples:
https://njbenjamin.com/bundle-3.htm
https://njbenjamin.com/bundle-4.htm
If you use the 1st example:
https://njbenjamin.com/flex/index_1.htm
You can play around with your browser console, to change the display of the container element between flex and inline-flex.
You need a bit more information so that the browser knows what you want. For instance, the children of the container need to be told "how" to flex.

<h1>Flex vs inline-flex</h1>
<cite>This pen is understand difference between
flex and inline-flex. Follow along to understand this basic property of css</cite>
<ul>
<li>Follow #1 in CSS:
<ul>
<li>Comment <code>display: flex</code></li>
<li>Un-comment <code>display: inline-flex</code></li>
</ul>
</li>
<li>
Hope you would have understood till now. This is very similar to situation of `inline-block` vs `block`. Lets go beyond and understand usecase to apply learning. Now lets play with combinations of A, B, C & D by un-commenting only as instructed:
<ul>
<li>A with D -- does this do same job as <code>display: inline-flex</code>. Umm, you may be right, but not its doesnt do always, keep going !</li>
<li>A with C</li>
<li>A with C & D -- Something wrong ? Keep going !</li>
<li>B with C</li>
<li>B with C & D -- Still same ? Did you learn something ? inline-flex is useful if you have space to occupy in parent of 2 flexboxes <code>.flex-con</code>. That's the only usecase</li>
</ul>

I am building a Windows 8 App in HTML5 and I am trying to center my app menu right in the middle of the screen. I know there are new CSS3 to apply this functionality, by using flexible boxes, however I am not able to recreate that. Here is my HTML

<div id="playControl">
<button>Back</button>
<button>Play</button>
<button>Forward</button>

There is some information here, but looks like isn't working properly (I guess they changed the property names)
Thanks
Here's how I do that. I use a grid instead of a flexbox at all. Let's say your div is inside a div called "parent". I would use...
#parent {
display:-ms-grid;
-ms-grid-columns:1fr;
-ms-grid-rows:1fr;
height:100%;
}
And then on your div I would use...
#yourDiv {
-ms-grid-column-align: center;
-ms-grid-row-align: center;
}
Notice that you need to give the parent div a single row and column and a height of 100%. Then you need to set the alignment for the child div (the initial value is 'stretch').
Hope that helps.
Brute force example... use css styles in real implementation...
You can fill the page with a flexbox like this... (note I used the default ms-flexbox css style to get things started and overrode with inline styling to get what I wanted)
<div class="ms-flexbox" style="width: 100%; height: 100%; -ms-flex-direction: column; -ms-flex-align: center; -ms-flex-pack: center;">
<button>Back</button>
<button>Play</button>
<button>Forward</button>
</div>
or your could create a 3x3 grid and put a smaller flexbox inside the middle cell.
