Flexbox css3 make a responsive centred row? - css

I have a 3 box example here all horizontally centered and trying to make them responsive, so if the resolution drops they will stack. I've tried doing this with flex box because it allows any box to grow and still lines up. Originally I put the boxes in bootstrap 3 row with the cols-lg (md etc) set but it would never unstack them! The outer wrapper (.wpr) will on implementation be a banner which is why I would like the positional boxes horizontally aligned where possible.
Note: The answer doesn't have to use flexbox!
Here is the fiddle
HTML
<div class="wpr">
<div class="box" style="background-color: red;">A B C</div>
<div class="box" style="background-color: blue;">2</div>
<div class="box" style="background-color: pink;">3</div>
</div>
CSS
.wpr
{
width: 100%;
background: grey;
padding: 10px 30px;
display: flex;
justify-content: center; /* align horizontal */
align-items: top; /* align vertical */
}
div.box
{
width: 200px;
min-width: 200px;
float: left;
margin: 0 5px;
padding: 30px;
text-align: center;
color: white;
font-size: 72px;
min-height: 100px;
}

You could add a flex-wrap: wrap; to .wpr as seen in my demo.

You just need to add the flex-wrap: wrap; property to the .wpr class.
.wpr
{
width: 100%;
background: grey;
padding: 10px 30px;
display: flex;
justify-content: center; /* align horizontal */
align-items: top; /* align vertical */
flex-wrap: wrap; <===
}

Centering DIV horizontally with uneven width DIVs on each side [duplicate]

Imagine the following layout, where the dots represent the space between the boxes:
[Left box]......[Center box]......[Right box]
When I remove the right box, I like the center box to still be in the center, like so:
[Left box]......[Center box].................
The same goes for if I would remove the left box.
................[Center box].................
Now when the content within the center box gets longer, it will take up as much available space as needed while remaining centered. The left and right box will never shrink and thus when where is no space left the overflow:hidden and text-overflow: ellipsis will come in effect to break the content;
[Left box][Center boxxxxxxxxxxxxx][Right box]
All the above is my ideal situation, but I have no idea how to accomplish this effect. Because when I create a flex structure like so:
.parent {
display : flex; // flex box
justify-content : space-between; // horizontal alignment
align-content : center; // vertical alignment
}
If the left and right box would be exactly the same size, I get the desired effect. However when one of the two is from a different size the centered box is not truly centered anymore.
Is there anyone that can help me?
Update
A justify-self would be nice, this would be ideal:
.leftBox {
justify-self : flex-start;
}
.rightBox {
justify-self : flex-end;
}
If the left and right boxes would be exactly the same size, I get the desired effect. However when one of the two is a different size the centered box is not truly centered anymore. Is there anyone that can help me?
Here's a method using flexbox to center the middle item, regardless of the width of siblings.
Key features:
pure CSS
no absolute positioning
no JS/jQuery
Use nested flex containers and auto margins:
.container {
display: flex;
}
.box {
flex: 1;
display: flex;
justify-content: center;
}
.box:first-child > span { margin-right: auto; }
.box:last-child > span { margin-left: auto; }
/* non-essential */
.box {
align-items: center;
border: 1px solid #ccc;
background-color: lightgreen;
height: 40px;
}
p {
text-align: center;
margin: 5px 0 0 0;
}
<div class="container">
<div class="box"><span>short text</span></div>
<div class="box"><span>centered text</span></div>
<div class="box"><span>loooooooooooooooong text</span></div>
</div>
<p>↑<br>true center</p>
Here's how it works:
The top-level div (.container) is a flex container.
Each child div (.box) is now a flex item.
Each .box item is given flex: 1 in order to distribute container space equally (more details).
Now the items are consuming all space in the row and are equal width.
Make each item a (nested) flex container and add justify-content: center.
Now each span element is a centered flex item.
Use flex auto margins to shift the outer spans left and right.
You could also forgo justify-content and use auto margins exclusively.
But justify-content can work here because auto margins always have priority.
8.1. Aligning with auto
margins
Prior to alignment via justify-content and align-self, any
positive free space is distributed to auto margins in that dimension.
Use three flex items in the container
Set flex: 1 to the first and last ones. This makes them grow equally to fill the available space left by the middle one.
Thus, the middle one will tend to be centered.
However, if the first or last item has a wide content, that flex item will also grow due to the new min-width: auto initial value.
Note Chrome doesn't seem to implement this properly. However, you can set min-width to -webkit-max-content or -webkit-min-content and it will work too.
Only in that case the middle element will be pushed out of the center.
.outer-wrapper {
display: flex;
}
.item {
background: lime;
margin: 5px;
}
.left.inner-wrapper, .right.inner-wrapper {
flex: 1;
display: flex;
min-width: -webkit-min-content; /* Workaround to Chrome bug */
}
.right.inner-wrapper {
justify-content: flex-end;
}
.animate {
animation: anim 5s infinite alternate;
}
#keyframes anim {
from { min-width: 0 }
to { min-width: 100vw; }
}
<div class="outer-wrapper">
<div class="left inner-wrapper">
<div class="item animate">Left</div>
</div>
<div class="center inner-wrapper">
<div class="item">Center</div>
</div>
<div class="right inner-wrapper">
<div class="item">Right</div>
</div>
</div>
<!-- Analogous to above --> <div class="outer-wrapper"><div class="left inner-wrapper"><div class="item">Left</div></div><div class="center inner-wrapper"><div class="item animate">Center</div></div><div class="right inner-wrapper"><div class="item">Right</div></div></div><div class="outer-wrapper"><div class="left inner-wrapper"><div class="item">Left</div></div><div class="center inner-wrapper"><div class="item">Center</div></div><div class="right inner-wrapper"><div class="item animate">Right</div></div></div>
The key is to use flex-basis. Then the solution is simple as:
.parent {
display: flex;
justify-content: space-between;
}
.left, .right {
flex-grow: 1;
flex-basis: 0;
}
CodePen is available here.
Here's an answer that uses grid instead of flexbox. This solution doesn't require extra grandchild elements in the HTML like the accepted answer does. And it works correctly even when the content on one side gets long enough to overflow into the center, unlike the grid answer from 2019.
The one thing this solution doesn't do is show an ellipsis or hide the extra content in the center box, as described in the question.
section {
display: grid;
grid-template-columns: 1fr auto 1fr;
}
section > *:last-child {
white-space: nowrap;
text-align: right;
}
/* not essential; just for demo purposes */
section {
background-color: #eee;
font-family: helvetica, arial;
font-size: 10pt;
padding: 4px;
}
section > * {
border: 1px solid #bbb;
padding: 2px;
}
<section>
<div>left</div>
<div>center</div>
<div>right side is longer</div>
</section>
<section>
<div>left</div>
<div>center</div>
<div>right side is much, much longer</div>
</section>
<section>
<div>left</div>
<div>center</div>
<div>right side is much, much longer, super long in fact</div>
</section>
Instead of defaulting to using flexbox, using grid solves it in 2 lines of CSS without additional markup inside the top level children.
HTML:
<header class="header">
<div class="left">variable content</div>
<div class="middle">variable content</div>
<div class="right">variable content which happens to be very long</div>
</header>
CSS:
.header {
display: grid;
grid-template-columns: [first] 20% auto [last] 20%;
}
.middle {
/* use either */
margin: 0 auto;
/* or */
text-align: center;
}
Flexbox rocks but shouldn't be the answer for everything. In this case grid is clearly the cleanest option.
Even made a codepen for your testing pleasure:
https://codepen.io/anon/pen/mooQOV
You can do this like so:
.bar {
display: flex;
background: #B0BEC5;
}
.l {
width: 50%;
flex-shrink: 1;
display: flex;
}
.l-content {
background: #9C27B0;
}
.m {
flex-shrink: 0;
}
.m-content {
text-align: center;
background: #2196F3;
}
.r {
width: 50%;
flex-shrink: 1;
display: flex;
flex-direction: row-reverse;
}
.r-content {
background: #E91E63;
}
<div class="bar">
<div class="l">
<div class="l-content">This is really long content. More content. So much content.</div>
</div>
<div class="m">
<div class="m-content">This will always be in the center.</div>
</div>
<div class="r">
<div class="r-content">This is short.</div>
</div>
</div>
Here is another way to do it, using display: flex in the parents and childs:
.Layout{
display: flex;
justify-content: center;
}
.Left{
display: flex;
justify-content: flex-start;
width: 100%;
}
.Right{
display: flex;
justify-content: flex-end;
width: 100%;
}
<div class = 'Layout'>
<div class = 'Left'>I'm on the left</div>
<div class = 'Mid'>Centered</div>
<div class = 'Right'>I'm on the right</div>
</div>
A slightly more robust grid solution looks like this:
.container {
overflow: hidden;
border-radius: 2px;
padding: 4px;
background: orange;
display: grid;
grid-template-columns: minmax(max-content, 1fr) auto minmax(max-content, 1fr);
}
.item > div {
display: inline-block;
padding: 6px;
border-radius: 2px;
background: teal;
}
.item:last-child > div {
float: right;
}
<div class="container">
<div class="item"><div contenteditable>edit the text to test the layout</div></div>
<div class="item"><div contenteditable>just click me and</div></div>
<div class="item"><div contenteditable>edit</div></div>
</div>
And here you can see it in Codepen: https://codepen.io/benshope2234/pen/qBmZJWN
I wanted the exact result shown in the question, I combined answers from gamliela and Erik Martín Jordán and it works best for me.
.parent {
display: flex;
justify-content: space-between;
}
.left, .right {
flex-grow: 1;
flex-basis: 0;
}
.right {
display: flex;
justify-content: flex-end;
}
you can also use this simple way to reach exact center alignment for middle element :
.container {
display: flex;
justify-content: space-between;
}
.container .sibling {
display: flex;
align-items: center;
height: 50px;
background-color: gray;
}
.container .sibling:first-child {
width: 50%;
display: flex;
justify-content: space-between;
}
.container .sibling:last-child {
justify-content: flex-end;
width: 50%;
box-sizing: border-box;
padding-left: 100px; /* .center's width divided by 2 */
}
.container .sibling:last-child .content {
text-align: right;
}
.container .sibling .center {
height: 100%;
width: 200px;
background-color: lightgreen;
transform: translateX(50%);
}

Althought I might be late on this one, all those solutions seems complicated and may not work depending on the cases you're facing.
Very simply, just wrap the component you want to center with position : absolute, while letting the other two with justify-content : space-between, like so :
CSS:
.container {
display: flex;
justify-content: space-between;
align-items: center;
background-color: lightgray;
}
.middle {
position: absolute;
margin-left: auto;
margin-right: auto;
/* You should adapt percentages here if you have a background ; else, left: 0 and right: 0 should do the trick */
left: 40%;
right: 40%;
text-align: center;
}
/* non-essential, copied from #Brian Morearty answer */
.element {
border: 1px solid #ccc;
background-color: lightgreen;
}
p {
margin: 5px;
padding: 5px;
}
<div class="container">
<p class="element">First block</p>
<p class="middle element">Middle block</p>
<p class="element">Third THICC blockkkkkkkkk</p>
</div>
Michael Benjamin has a decent answer but there is no reason it can't / shouldn't be simplified further:
.container {
display: flex;
}
.box {
flex: 1;
display: flex;
justify-content: center;
}
.box:first-child { justify-content: left; }
.box:last-child { justify-content: right; }
And html
<div class="container">
<div class="box">short text</div>
<div class="box">centered tex</div>
<div class="box">loooooooooooooooong text</div>
</div>

As a note, in the CSS rule for the flex container, place the regular display: flex property after all the prefix-versions.
For it to work also in IE11, use width: 50% instead of flex: 50%, combined with box-sizing: border-box, where borders/padding gets included in the set width.
.wrapper {
display: -ms-flexbox;
display: -webkit-flex;
display: -moz-box;
display: flex;
flex-wrap: wrap;
}
.box {
box-sizing: border-box;
width: 50%;
padding: 0 30px 10px;
text-align: center;
color: #8988DB;
border: 1px solid black;
}
<div class="wrapper">
<div class="box"><br>Valerian Root</div>
<div class="box"><br>Lavender</div>
<div class="box"><br>Lemon Balm</div>
<div class="box"><br>Chamomile</div>
<div class="box"><br>Passion Flower</div>
<div class="box"><br>Hops</div>
<div class="box"><br>Rooibos</div>
<div class="box"><br>Cinnamon</div>
</div>
Step into CSS Grid, it's ideal for this use case. Your use case is so simple, you only need three lines of CSS to pull it off.
.wrapper {
display: grid;
grid-template-columns: 1fr 1fr; // creates two responsive columns
grid-gap: 10px; // puts 10px between each node in the grid
}
Looks like all you need is a proper CSS reset, specifically, the box-sizing property so that borders are not included in the width calculations.
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
.wrapper {
display: flex;
flex-wrap: wrap;
}
.box {
flex: 50%;
text-align: center;
padding-bottom: 10px;
color: #8988DB;
border: 1px solid black;
}
<div class="wrapper">
<div class="box"><br>Valerian Root</div>
<div class="box"><br>Lavender</div>
<div class="box"><br>Lemon Balm</div>
<div class="box"><br>Chamomile</div>
<div class="box"><br>Passion Flower</div>
<div class="box"><br>Hops</div>
<div class="box"><br>Rooibos</div>

Flexbox: Keep text with line break horizontally centered

I have a flex container with some text (an h1, for example) that has a line break due to the width of the container. I'm trying to keep the text inline so that it doesn't automatically take up 100% of the width of the container, so that it stays centered horizontally, but having Flex on the container breaks this. I've tried using align-self: center on the h1 and a number of other things with no luck. Any help would be much appreciated.
Edit: I want to keep the text itself left-aligned, but have the h1 element centered within the container.
.container {
width: 250px;
background-color: tomato;
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
}
h1 {
display: inline; /* should only take as much space as it needs */
align-self: center;
}
<div class="container">
<h1>Text text sdfsdlfkjs</h1>
</div>
Is this what are you looking for?
.container {
width: 250px;
background-color:tomato;
display: flex;
flex-direction: column;
justify-content: center;
}
h1 {
width: 90%;
margin-left: auto;
margin-right: auto;
border: 1px solid white;
}

Closed 5 years ago.
Whilst trying to answer this question, I was trying to come up with a flex solution. The closest I could get was this:
.container {
height: 500px;
width: 500px;
background-color: red;
display: flex;
flex-direction: row;
flex-wrap: wrap;
justify-content:space-between; /* puts spacing between left and right column */
}
.headerTitle {
width:100%;
height: 24px;
margin: 24px 24px 0;
padding: 0;
line-height: 24px;
}
.sectionClass {
width: 249px;
height: 200px;
background-color: yellow;
}
.rightSideDiv {
width: 249px;
height: 200px;
border: 4px solid green;
box-sizing:border-box; /* need this otherwise border will take an extra 8px width in some browsers */
}
<aside>
<div class="container">
<header class="headerTitle"> Header Title </header>
<section class="sectionClass"> . </section>
<div class="rightSideDiv"> </div>
</div>
</aside>
However, I couldn't make the 2 lower boxes start flush to the top heading. Is there a way of doing this using flex? I tried align-items and align-self but that didn't seem to do anything.
I also tried adding a pseudo element to the container with flex-grow:1; but it didn't grow in the required manner.
It would be interesting to see if flex can handle this as I'm still trying to learn the intricacies of it
Just add align-content: flex-start to the .container div:
.container {
height: 500px;
width: 500px;
background-color: red;
display: flex;
flex-direction: row;
flex-wrap: wrap;
justify-content:space-between; /* puts spacing between left and right column */
align-content: flex-start;
}
.headerTitle {
width:100%;
height: 24px;
margin: 24px 24px 0;
padding: 0;
line-height: 24px;
}
.sectionClass {
width: 249px;
height: 200px;
background-color: yellow;
}
.rightSideDiv {
width: 249px;
height: 200px;
border: 4px solid green;
box-sizing:border-box; /* need this otherwise border will take an extra 8px width in some browsers */

Image height inside flexbox not working in Chrome

I have a div using flexbox to center its items. Inside this div I have 3 elements, one of them is an image.
<div id="flex-container">
<div id="container1"></div>
<img src="#" alt="">
<div id="container2"></div>
</div>
#container1 and #container2 have their own height, and the img should use the remaining height inside #flex-container.
This snippet works on Firefox, but doesn't work in Chrome. (jsfiddle)
#flex-container{
height: 300px;
width: 500px;
display: flex;
display: -webkit-flex;
flex-flow: column nowrap;
-webkit-flex-flow: column nowrap;
justify-content: center;
-webkit-justify-content: center;
align-items: center;
-webkit-align-items: center;
border: 5px solid black;
}
#container1, #container2{
height: 100px;
width: 300px;
background: orange;
flex: 1 0 auto;
-webkit-flex: 1 0 auto;
}
<div id="flex-container">
<div id="container1">300x100 px</div>
<img src="http://i.imgur.com/RRUe0Mo.png" alt="">
<div id="container2">300x100 px</div>
</div>
Chrome needs -webkit- prefixes for flexbox, but the issue doesn't seem to be this.
What can be happening? Is a browser bug or I'm forgetting something?
There are two problems you need to overcome:
Firefox solves them both on its own, but Chrome needs assistance.
Problem #1
The first problem is that flex items, by default, cannot be smaller than their content. An initial setting on flex items is min-height: auto.
Therefore, a flex item with a replaced element, like an image, will default to the inherent size of the image. The item cannot be made smaller, unless you override the initial setting (use min-height: 0).
#flex-container {
height: 300px;
width: 500px;
display: flex;
flex-flow: column nowrap;
justify-content: center;
align-items: center;
border: 5px solid black;
}
#container1, #container2 {
height: 100px;
width: 300px;
background: orange;
flex: 1 0 auto;
}
img { min-height: 0; } /* NEW */
<div id="flex-container">
<div id="container1">300x100 px</div>
<img src="http://i.imgur.com/RRUe0Mo.png" alt="">
<div id="container2">300x100 px</div>
</div>
A complete explanation of this issue can be found here:
Why doesn't flex item shrink past content size?
Problem #2
Then you hit the second problem: keeping the aspect ratio. This is a common problem in flex containers. One option is to define a height for the image:
#flex-container {
height: 300px;
width: 500px;
display: flex;
flex-flow: column nowrap;
justify-content: center;
align-items: center;
border: 5px solid black;
}
#container1, #container2 {
height: 100px;
width: 300px;
background: orange;
flex: 1 0 auto;
}
img { min-height: 0; height: 100px; } /* NEW */
<div id="flex-container">
<div id="container1">300x100 px</div>
<img src="http://i.imgur.com/RRUe0Mo.png" alt="">
<div id="container2">300x100 px</div>
</div>
