Why does flexbox stretch my image rather than retaining aspect ratio? - html

Flexbox has this behaviour where it stretches images to their natural height. In other words, if I have a flexbox container with a child image, and I resize the width of that image, the height doesn't resize at all and the image gets stretched.
div {
display: flex;
flex-wrap: wrap;
}
img {
width: 50%
}
<div>
<img src="https://i.imgur.com/KAthy7g.jpg" >
<h1>Heading</h1>
<p>Paragraph</p>
</div>
What causes this?

It is stretching because align-self default value is stretch.
Set align-self to center.
align-self: center;
See documentation here:
align-self

The key attribute is align-self: center:
.container {
display: flex;
flex-direction: column;
}
img {
max-width: 100%;
}
img.align-self {
align-self: center;
}
<div class="container">
<p>Without align-self:</p>
<img src="http://i.imgur.com/NFBYJ3hs.jpg" />
<p>With align-self:</p>
<img class="align-self" src="http://i.imgur.com/NFBYJ3hs.jpg" />
</div>

I faced the same issue with a Foundation menu. align-self: center; didn't work for me.
My solution was to wrap the image with a <div style="display: inline-table;">...</div>

Adding margin to align images:
Since we wanted the image to be left-aligned, we added:
img {
margin-right: auto;
}
Similarly for image to be right-aligned, we can add margin-right: auto;. The snippet shows a demo for both types of alignment.
Good Luck...
div {
display:flex;
flex-direction:column;
border: 2px black solid;
}
h1 {
text-align: center;
}
hr {
border: 1px black solid;
width: 100%
}
img.one {
margin-right: auto;
}
img.two {
margin-left: auto;
}
<div>
<h1>Flex Box</h1>
<hr />
<img src="https://via.placeholder.com/80x80" class="one"
/>
<img src="https://via.placeholder.com/80x80" class="two"
/>
<hr />
</div>

It is stretching because align-self default value is stretch.
there is two solution for this case :
1. set img align-self : center
OR
2. set parent align-items : center
img {
align-self: center
}
OR
.parent {
align-items: center
}

I had a similar issue while making my navigation bar, but none of the above worked for me.
My solution was adding height: 100% for the image.
If you're aligning the items horizontally, add width: 100% instead.
EDIT: Chrome seems to add this value by default now, but you'll need to add this for compatibility.

Use one of the CSS settings below: contain or cover is most popular
.my-img {
object-fit: contain;
}
or
.my-img {
object-fit: cover;
}

I had a similar issue, my solution was adding flex-shrink: 0; to the image.

Center an inline element that is a button [duplicate]

Is the property text-align: center; a good way to center an image using CSS?
img {
text-align: center;
}
That will not work as the text-align property applies to block containers, not inline elements, and img is an inline element. See the W3C specification.
Use this instead:
img.center {
display: block;
margin: 0 auto;
}
<div style="border: 1px solid black;">
<img class="center" src ="https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-icon.png?v=c78bd457575a">
</div>
That doesn't always work... if it doesn't, try:
img {
display: block;
margin: 0 auto;
}
I came across this post, and it worked for me:
img {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
margin: auto;
}
<div style="border: 1px solid black; position:relative; min-height: 200px">
<img src="https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-icon.png?v=c78bd457575a">
</div>
(Vertical and horizontal alignment)
Not recommendad:
Another way of doing it would be centering an enclosing paragraph:
<p style="text-align:center"><img src="https://via.placeholder.com/300"></p>
Update:
My answer above is correct if you want to start learning HTML/CSS, but it doesn't follow best practices
Actually, the only problem with your code is that the text-align attribute applies to text (yes, images count as text) inside of the tag. You would want to put a span tag around the image and set its style to text-align: center, as so:
span.centerImage {
text-align: center;
}
<span class="centerImage"><img src="http://placehold.it/60/60" /></span>
The image will be centered. In response to your question, it is the easiest and most foolproof way to center images, as long as you remember to apply the rule to the image's containing span (or div).
You can do:
<center><img src="..." /></center>
There are three methods for centering an element that I can suggest:
Using the text-align property
.parent {
text-align: center;
}
<div class="parent">
<img src="https://placehold.it/60/60" />
</div>
Using the margin property
img {
display: block;
margin: 0 auto;
}
<img src="https://placehold.it/60/60" />
Using the position property
img {
display: block;
position: relative;
left: -50%;
}
.parent {
position: absolute;
left: 50%;
}
<div class="parent">
<img src="https://placehold.it/60/60" />
</div>
The first and second methods only work if the parent is at least as wide as the image. When the image is wider than its parent, the image will not stay centered!!!
But:
The third method is a good way for that!
Here's an example:
img {
display: block;
position: relative;
left: -50%;
}
.parent {
position: absolute;
left: 50%;
}
<div class="parent">
<img src="http://imgsv.imaging.nikon.com/lineup/lens/zoom/normalzoom/af-s_dx_18-140mmf_35-56g_ed_vr/img/sample/img_01.jpg" />
</div>
On the container holding image you can use a CSS 3 Flexbox to perfectly center the image inside, both vertically and horizontally.
Let's assume you have <div class="container"> as the image holder:
Then as CSS you have to use:
.container {
display: flex;
align-items: center;
justify-content: center;
height: 100%;
}
And this will make all your content inside this div perfectly centered.
Only if you need to support ancient versions of Internet Explorer.
The modern approach is to do margin: 0 auto in your CSS.
Example here: http://jsfiddle.net/bKRMY/
HTML:
<p>Hello the following image is centered</p>
<p class="pic"><img src="https://twimg0-a.akamaihd.net/profile_images/440228301/StackoverflowLogo_reasonably_small.png"/></p>
<p>Did it work?</p>
CSS:
p.pic {
width: 48px;
margin: 0 auto;
}
The only issue here is that the width of the paragraph must be the same as the width of the image. If you don't put a width on the paragraph, it will not work, because it will assume 100% and your image will be aligned left, unless of course you use text-align:center.
Try out the fiddle and experiment with it if you like.
img{
display: block;
margin-right: auto;
margin-left: auto;
}
If you are using a class with an image then the following will do
class {
display: block;
margin: 0 auto;
}
If it is only an image in a specific class that you want to center align then following will do:
class img {
display: block;
margin: 0 auto;
}
The simplest solution I found was to add this to my img-element:
style="display:block;margin:auto;"
It seems I don't need to add "0" before the "auto" as suggested by others. Maybe that is the proper way, but it works well enough for my purposes without the "0" as well. At least on latest Firefox, Chrome, and Edge.
Simply change parent align :)
Try this one on parent properties:
text-align:center
You can use text-align: center on the parent and change the img to display: inline-block → it therefore behaves like a text-element and is will be centered if the parent has a width!
img {
display: inline-block
}
To center a non background image depends on whether you want to display the image as an inline (default behavior) or a block element.
Case of inline
If you want to keep the default behavior of the image's display CSS property, you will need to wrap your image inside another block element to which you must set text-align: center;
Case of block
If you want to consider the image as a block element of its own, then text-align property does not make a sens, and you should do this instead:
IMG.display {
display: block;
margin-left: auto;
margin-right: auto;
}
The answer to your question:
Is the property text-align: center; a good way to center an image
using CSS?
Yes and no.
Yes, if the image is the only element inside its wrapper.
No, in case you have other elements inside the image's wrapper because all the children elements which are siblings of the image will inherit the text-align property: and may be you would not like this side effect.

Centering things
.img-container {
display: flex;
}
img {

}
this will make the image center in both vertically and horizontally
I would use a div to center align an image. As in:
<div align="center"><img src="your_image_source"/></div>
If you want to set the image as the background, I've got a solution:
.image {
background-image: url(yourimage.jpg);
background-position: center;
}
One more way to scale - display it:
img {
width: 60%; /* Or required size of image. */
margin-left: 20% /* Or scale it to move image. */
margin-right: 20% /* It doesn't matters much if using left and width */
}
Use this to your img CSS:
img {
margin-right: auto;
margin-left: auto;
}
Use Grids To Stack images. It is very easy here is the code
.grid {
display:grid;
}
.grid img {
display:block;
margin:0 auto;
}
If your img element is inside a div, which is itself inside another div whose display has been set as flexbox, as in my case here:
(HTML)
<nav class="header">
<div class="image">
<img
src=troll
alt="trollface"
></img>
</div>
<div class="title">
Meme Generator
</div>
<div class="subtitle">
React Course - Project 3
</div>
</nav>
(CSS)
.header{
display: flex;
}
.image{
width: 5%;
height: 100%;
}
.image > img{
width: 100%;
}
You could set your .image div to align itself vertically by doing this:
.image{
width: 5%;
height: 100%;
align-self: center;
}
display: block with margin: 0 didn't work for me, neither wrapping with a text-align: center element.
This is my solution:
img.center {
position: absolute;
transform: translateX(-50%);
left: 50%;
}
translateX is supported by most browsers
I discovered that if I have an image and some text inside a div, then I can use text-align:center to align the text and the image in one swoop.
HTML:
<div class="picture-group">
<h2 class="picture-title">Picture #1</h2>
<img src="http://lorempixel.com/99/100/" alt="" class="picture-img" />
<p class="picture-caption">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Temporibus sapiente fuga, quia?</p>
</div>
CSS:
.picture-group {
border: 1px solid black;
width: 25%;
float: left;
height: 300px;
#overflow:scroll;
padding: 5px;
text-align:center;
}
CodePen:
https://codepen.io/artforlife/pen/MoBzrL?editors=1100
Sometimes we directly add the content and images on the WordPress administrator inside the pages. When we insert the images inside the content and want to align that center. Code is displayed as:
**<p><img src="https://abcxyz.com/demo/wp-content/uploads/2018/04/1.jpg" alt=""></p>**
In that case you can add CSS content like this:
article p img{
margin: 0 auto;
display: block;
text-align: center;
float: none;
}
Use:
<dev class="col-sm-8" style="text-align: center;"><img src="{{URL('image/car-trouble-with-clipping-path.jpg')}}" ></dev>
I think this is the way to center an image in the Laravel framework.
To center an image with CSS.
img{
display: block;
margin-left: auto;
margin-right: auto;
}

If you want to center image to the center both vertically and horizontaly, regardless of screen size, you can try out this code
img{
display: flex;
justify-content:center;
align-items: center;
height: 100vh;
}

Resizing flex div image instead of cropping

I have a flex with 3 images and I would want them resize if a window is too small right now when window gets smaller first they reorder so they stack vertically and when window gets even smaller the picture gets squeezed instead of resized I would want to keep the image with proper aspect ratio.
.images {
display: flex;
justify-content: center;
flex-wrap: wrap;
}
.images div {
display: flex;
margin: 1rem;
}
.images img {
height: 16rem;
max-width: 100%;
}
<div class="images">
<div>
<img src="http://placehold.it/150x200">
</div>
<div>
<img src="http://placehold.it/150x150">
</div>
<div>
<img src="http://placehold.it/150x100">
</div>
</div>
First of all the basic thing to keep in mind to maintain aspect ratio (I'm sure you already know this) is to restrict only one dimension of an image. (Read this)
You are already breaking this in your code- resulting in the 'squeeze' at smaller screen widths:
.images img {
height: 16rem;
max-width: 100%;
}
When window gets smaller first they reorder so they stack vertically
and when window gets even smaller the picture gets squeezed instead of
resized I would want to keep the image with proper aspect ratio.
So here are your options:
So I guess you should remove max-width: 100% and keep width adjust depending on the 16rem height.
.images {
display: flex;
justify-content: center;
flex-wrap: wrap;
}
.images div {
display: flex;
margin: 1rem;
}
.images img {
height: 16rem;
/*max-width: 100%;*/
}
<div class="images">
<div>
<img src="http://placehold.it/150x200">
</div>
<div>
<img src="http://placehold.it/150x150">
</div>
<div>
<img src="http://placehold.it/150x100">
</div>
</div>
Well, for small widths you would have horizontal scroll. According to the particular case, if needed you can use some media queries to adjust height at small screen widths.
Let me know your feedback on this. Thanks!
.images img{
height: 16rem;
max-width: 100%;
object-fit: contain;
}
For the aspect ratio fix, you can just run with the CSS3 object-fit property. CSS3 Object-Fit
Set it on your image as:
.images img {
object-fit: contain;
}
That should do the trick of keeping the aspect ratio of the image.
As for the Wrapping that takes place within the flex container, just take out the flex-wrap property in your code so they'll all stay on the same row, rather than wrapping as the container size gets smaller.
EDIT
Try adding a align-self CSS Property to the .images img, see if that's what you're looking for:
.images {
display: flex;
justify-content: center;
flex-wrap: wrap;
}
.images div {
display: flex;
margin: 1rem;
}
.images img {
width: 100%;
height: auto;
object-fit: contain;
align-self: flex-start;
}
Hope this helps!

Force an image to ALWAYS stay at the middle of a div

I'm searching ways to force an image element to stay always aligned at the middle of a div even when the div element gets too small to properly center the image. Here's an explanation of what I want to do: Question.jpg
I need the solution to be purely CSS if possible?
Using this centering trick should give you what you want:
img {
position:relative; (or absolute, it depends on your needs)
top:50%;
left:50%;
transform:translate(-50%, -50%);
}
This keeps the image centered no matter the size of the container it is in. It doesn't resize the image though. Based on that pic you out it seems like you didn't want that.
Use the following grid layout and styles:
style{
.container{ max-width:800px; margin:0 auto;}
}
#media
only screen and (max-width:600px) {
.mCenter{margin:0 auto;}
.mImage600:{width:100%; height:auto;}
}
<div class=container>
<div class=mCenter>
<img class=mImage600 src 'img.jpg' width=600 >
</div>
<div>
Fiddle
img{
margin: 0 auto;
}
could help
You can do like this, using display flex.
div {
width: 100%;
height: 500px;
border: 1px solid gray;
display: flex;
align-items: flex-start;
text-align: center;
}
img {
align-self: center;
margin: 0 auto;
}
<div>

Vertically centering with flexbox

I'm trying to center a div on a webpage using flexbox. I'm setting the following CSS properties. I see that it's being centered horizontally, but not vertically.
.flex-container {
display: flex;
align-items: center;
justify-content: center;
}
Here's the fiddle: JSFIDDLE
Can you explain what I'm doing wrong?
A <div> element without an explicit height defaults to the height of it's contents, as all block elements do. You'd probably want to set it to 100% of it's parent, the <body>, but that's not enough, since that is also a block element. So again, you need to set that to 100% height, to match it's parent, the <html>. And yet again, 100% is still required.
But once all that is done, you get that annoying vertical scroll bar. That's a result of the default margin the body has, and the way the box model is defined. You have several ways you can combat that, but the easiest is to set your margins to 0.
See corrected fiddle.
html, body {
height: 100%;
margin: 0px;
}
.flex-container {
display: flex;
align-items: center;
justify-content: center;
height: 100%;
}
.item {
background-color: blue;
height: 50px;
width: 50px;
}
<div class="flex-container">
<div class="item">
</div>
</div>
You just need to set html, body, and your flex container to height: 100%. The reason it wasn't working is that your flex container didn't have an explicit height set, so it defaulted to the height of its contents.
Live Demo:
html, body {
height: 100%;
}
.flex-container {
display: flex;
align-items: center;
justify-content: center;
height: 100%;
}
.item {
background-color: blue;
height: 50px;
width: 50px;
}
<div class="flex-container">
<div class="item">
</div>
</div>

center image in div with overflow hidden

I have an image of 400px and a div that is smaller (the width is not always 300px as in my example). I want to center the image in the div, and if there is an overflow, hide it.
Note: I must keep the position:absolute on the image. I'm working with css-transitions, and if I use position:relative, my image shakes a bit (https://web.archive.org/web/20120528225923/http://ta6.maxplus.be:8888/).

http://jsfiddle.net/wjw83/1/
You should make the container relative and give it a height as well and you're done.
http://jsfiddle.net/jaap/wjw83/4/
.main {
width: 300px;
margin: 0 auto;
overflow: hidden;
position: relative;
height: 200px;

img.absolute {
left: 50%;
margin-left: -200px;
position: absolute;
}
<div class="main">
<img class="absolute" src="http://via.placeholder.com/400x200/A44/EED?text=Hello" alt="" />
</div>
<br />
<img src="http://via.placeholder.com/400x200/A44/EED?text=Hello" alt="" />
If you want to you can also center the image vertically by adding a negative margin and top position: http://jsfiddle.net/jaap/wjw83/5/
None of the above solutions were working out well for me. I needed a dynamic image size to fit in a circular parent container with overflow:hidden

border-radius:50%;
overflow:hidden;

For me flex-box worked perfect to center the image.
this is my html-code:
<div class="img-wrapper">
<img src="..." >
</div>
and this i used for css:
I wanted the Image same wide as the wrapper-element, but if the height is greater than the height of the wrapper-element it should be "cropped"/not displayed.
.img-wrapper{
width: 100%;
height: 50%;
overflow: hidden;
display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
}
img {
height: auto;
width: 100%;
}
working solution with flex-box for posterity:
main points:
overflow hidden for wrapper
image height and width must be specified, cannot be percentage.
use any method you want to center the image.
wrapper {
width: 80;
height: 80;
overflow: hidden;
align-items: center;
justify-content: center;
}
image {
width: min-content;
height: min-content;
}
<html>
<head>
<style type="text/css">
.div-main{
height:200px;
width:200px;
overflow: hidden;
background:url(img.jpg) no-repeat center center
}
</style>
</head>
<body>
<div class="div-main">
</div>
</body>
just make sure how you are using image through css background use backgroud image position like background: url(your image path) no-repeat center center; automatically it wil align center to the screen.
this seems to work on our site, using your ideas and a little math based upon the left edge of wrapper div. It seems redundant to go left 50% then take out 50% extra margin, but it seems to work.
div.ImgWrapper {
width: 160px;
height: 160px
overflow: hidden;
text-align: center;
}
img.CropCenter {
left: 50%;
margin-left: -100%;
position: relative;
width: auto !important;
height: 160px !important;
}
<div class="ImgWrapper">
<img class="CropCenter" src="img.png">
</div>
I have been trying to implement Jaap's answer inside this page of my recent site, with one difference : the .main {height:} was set to auto instead of a fixed px value.
As responsive developer i am looking for a solution to synchronize the image height with the left floating text element, yet only in case my text height becomes greater then my actual image height.
In that case the image should not be rescaled, but cropped and centered as decribed in the original question here above.
Can this be done ?
You can simulate the behaviour by slowly downsizing the browser's width.
This issue is a huge pain in the a.. but I finally got it.
I've seen a lot of complicated solutions. This is so simple now that I see it.
.parent {
width:70px;
height:70px;
}
.child {
height:100%;
width:10000px; /* Or some other impossibly large number */
margin-left: -4965px; /* -1*((child width-parent width)/2) */
}
.child img {
display:block; /* won't work without this */
height:100%;
margin:0 auto;
}
