Resize Images as viewport resizes without sides being cut off - css

I have a CSS problem. I have an image that is 1024x500 pixels. Now the problem is, whenever the browser window/viewport changes width below the width of the image(1024px), the image starts to get cut off. Now as you can see, I set the container width to 100% when the viewport size goes below 1024px, and it does resize proportionally, but the sides of my image get cut off more and more as the browser resizes(smaller).
Could anyone help me get my image to resize dynamically pixel for pixel (without losing any of the original picture - no cut offs)?
Check out my webpage and resize the browser window to see what I mean. Pay attention to the sides of the images getting cut away...
HTML: Note my Original image is 1024x500
<div class="ei-slider">
<ul class="ei-slider-large">
<li>
<img src="http://lamininbeauty.co.za/images/large/makeup.jpg" alt="Vertical Sunbed TanCan"/>
</li>
</ul>
</div>
CSS:
The normal CSS for large screens
.ei-slider{
position: relative;
width: 1024px;
height: 500px;
margin: 0 auto;
}
.ei-slider-large{
height: 100%;
width: 100%;
position:relative;
overflow: hidden;
}
.ei-slider-large li{
position: absolute;
top: 0px;
left: 0px;
overflow: hidden;
height: 100%;
width: 100%;
}
.ei-slider-large li img{
width: 100%;
}
For when the Browser window goes below the image width: 1024px:
#media screen and (max-width : 1023px){
.ei-slider{
width: 100%;
}
}
For smaller screens when my images are cut off: Note my Original image is 1024x500
#media screen and (max-width: 930px) and (min-width : 831px){
.ei-slider{
width: 100%;
}
.ei-slider-thumbs li a{
font-size: 11px;
}
.ei-slider-large li{
position: absolute;
top: 0px;
left: 0px;
overflow: visible;
height: 100%;
width: 100%;
}
.ei-slider-large li img{ /*HERE IS MY PROBLEM*/
width: 930px;
height: 454px;
}
}
Thank you!

you use:
max-width: 100%;
height: auto;
width: auto; /* for ie9 */
This will make whatever you assign the css to resize dynamically to fit its container based on the max-width: 100% statement. If you would like it differently, change the max width statement accordingly.

I have a simple solution for that. Just give the width parameter in terms of view-port percentage.
Syntax :
width: <Percentage>vw;
Example :
<img src="Resources/Head.png" alt="" style="width: 100vw; height: 85px">
Here, the height of the image is fixed but the width will be resized to 100% of the view-port, whatever its size may be.
Hope this helps :)

I had the same problem because I'm using the same jquery plugin (ie-slider). I found out that the image is passed additional (inline) styles from the Javascript code and in fact it is just shifted-left and not actually cut off. The code passes dynamic values to the tag which are got from the image itself at the time of re/load in a particular viewport width. The author uses this in the .js file.
var $img = $(this);
imgDim = _self._getImageDim( $img.attr('src')); //gets the dimensions from the image
He then gives the image a margin-left like so
$img.css({marginLeft: imgDim.left}); //assigns a new margin-left, overrides any value set for this property in the .css file because it's inline
When the viewport width gets smaller this is always a negative value. The work around is to set
$img.css({marginLeft: 0});
It worked fine for me after, with no arising issues from the change. Good luck.

Scale dynamic image with different widths and heights

I have image in the header and populate its source from the database, so it has different width and height. Image dimensions could be max 2000x2000px. I'm trying to scale it but when it's very large e.g more than 1000px it's very big and it's not looking good.
This is what I currently have.
#image {
position: absolute;
display: block;
top: 20px;
left: 20px;
height: 50px;
}
<div id="wrapper">
<img src="some-dynamic-url" id="image">
</div>
I've also tried with background-size: cover but it's not stretched and how to preserve the aspect ratio and set max-width and max-height not to be so big?
Updated. My current code is the following:
#image {
display: block;
top: 20px;
left: 20px;
width: 100%;
max-width: 170px;
}
<div id="wrapper">
<img src="some-dynamic-url" id="image">
</div>
Will the height always be 50px? If not, you should remove that from your CSS and instead use height: auto;.
Also, if it starts to not look so great at 1000px by 1000px, maybe set width: 1000px; and max-width: 85%; to keep it at that width and make it responsive on smaller screens. You can adjust the max-width value to your liking or remove it.
So, the CSS would change to:
#image {
position: absolute;
display: block;
top: 20px;
left: 20px;
width: 1000px;
max-width: 85%; /* adjust as needed or remove */
height: auto;
}
Here's an example.
If I'm understanding correctly, you have a header container area where various images get populated, and sometimes the images are too big for the container and not looking good. (A screenshot would be helpful if my summary is wrong.)
The trick here is to set the image width to 100%, then set a max-width to either the image or the header container. (I picked 1200px for this example.) That ensures that your image will fill up all of the space, but not go over.
NOTE: this will cause images with widths smaller than 1200px to be stretched to fit, and may not look good either and would require some more coding to fix.
#image {
position: absolute;
display: block;
top: 20px;
left: 20px;
width: 100%;
max-width: 1200px;
}
<div id="wrapper">
<img src="https://upload.wikimedia.org/wikipedia/commons/c/cc/ESC_large_ISS022_ISS022-E-11387-edit_01.JPG" id="image">
</div>
However, if you're looking for a work-around for images that are smaller than 2000px wide, I'd suggest something like centering them with a colored background, or perhaps tiling them. Those solutions will be good for some content, and ugly for others - it depends what you images are like and how the site looks. But those are some ideas.
You may want to use the simple trick to automatically fit size with:
img { max-width: 1200px; height: auto;}
I guess 50px for height is not a must since you thought using "cover" in backround property. Also if you wish this sort of behavior from your image, you can add "object-fit: cover;".
Read more here: https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit
EDIT
You can also use that version of the "trick":
img { max-height: 100px; width: auto; }
Note: Using files that big for logo is not recomand. If you got access tto database you should consider save a copy to more light version with less pixels.

BS carousel image distorted on mobile and on smaller size browser

I'm Making a BS Carousel. Images look out of place and don't cover carousel completely when browser is smaller and text doesn't stay centered. How can I figure this out? I haven't found an answer that could help me.
This is my CSS:
.carousel-inner {
height: 400px; }
.carousel-caption {
padding-bottom: 30%;
}
Here is the site: ' http://machinist-alec-32224.bitballoon.com '
Well at the moment your .carousel-caption has bottom padding set at 30%. On bigger screens that padding moves caption out of carousel. You should change that to a margin.
Also, your images stretch because you gave them fixed height but in the same time you expect them to stretch till they fill 100% of website width. You should set fixed height and on carousel item and not on image.
This CSS should give better results:
.carousel-caption {
margin-bottom: 125px;
}
.carousel-inner> .item {
margin: 0 auto;
height: 500px;
}
.carousel .item > img {
height: auto;
min-height:500px;
min-width: 100%;
}
You need to made the image resonsive. Something like that:
<img src="IMAGE LINK" border="0" class="responsive-image" alt="Null">
.responsive-image{
height:auto;
width:100%;
}

Dynamically scale images by height using pure CSS in Chrome 27 and above

Thanks to James Montagne's solution I built a one-row-gallery which scales images in a specific behaviour just using CSS.
Works great - except in Chrome 27 and above. Here the images' width stay at the initial value while the heights scale properly.
Please check this Fiddle or the code below:
HTML:
<div>
<img src="http://placekitten.com/200/300" class="vert"/>
<img src="http://placekitten.com/500/200" class="horiz"/>
<img src="http://placekitten.com/200/300" class="vert"/>
<img src="http://placekitten.com/400/300" class="horiz"/>
<img src="http://placekitten.com/200/300" class="vert"/>
</div>
CSS:
body,html{
height: 100%;
}
div{
white-space: nowrap;
height: 100%;
}
img{
min-height: 200px;
height: 100%;
vertical-align: top;
}
.horiz{
max-height: 300px;
}
.vert{
max-height: 500px;
}
I already dug through the Chrome 27 changelog (~13MB) but didn't find any useful info on that matter.
Any ideas how to avoid the images to blur on a window resize in Chrome >= 27?
If you want to change the dimensions of images with CSS, you should choose one dimension to change and let the other adjust automatically.
In this case, if you're more concerned with the width of the images, you could get rid of min-height and do something like this:
body,html{
height: 100%;
}
div{
height: 100%;
width: 100%;
padding: 0;
}
img{
float: left;
height: auto;
vertical-align: top;
width: 19%;
margin: 0.5%;
}
See example here.
Since I know you have a row of 5 images, we can use a width of 19% of the div width and fit them nicely.
EDIT
On the other hand, if you're looking to control minimum and maximum heights, you can wrap your images in a container, specify an explicit height on that container, and position the images within the container. Here you lose the ability to control keeping all images on one line while maintaining the original aspect ratio.
This example is here.

How to always center a flexible square in viewport with pure CSS?

I know this question: Height equal to dynamic width (CSS fluid layout)
But I want more!! I want a flexible container which has always the aspect ratio of a square but with max-height and max-width of 100% of the page (the window element) and on the top of it is always vertically and horizontally centered.
Like this:
// Container matches height of the window
// container-height = 100%; container-width = absolute-container-height
-page/browser-window-
- ####### -
- #cont-# -
- #ainer# -
- ####### -
---------------------
// container matches width of the window
// container-width = 100%; container-height = absolute-container-width
--page---
- -
- -
-#######-
-#######-
-#######-
-#######-
- -
- -
---------
Is it possible to achieve this with pure css (and even better cross-browser)?
Edit:
I know there is calc() for css3, but due to the poor mobile browser-support, I don't want to use it.
Edit2:
Seems like, I didn't make myself clear enough. I need height and width of the wrapper to match the height OR the width of the window, depending on which is smaller.The square-container should never exceed the smaller value of the window-height/width.
This is, how it would be done with jQuery:
// container/#main-wrapper has top: 50%, left: 50%, position: absolute via css
$(window).resize(function () {
var $ww = $(window).width();
var $wh = $(window).height();
if ($ww > $wh) {
$('#main-wrapper').css({
height: $wh,
width: $wh,
marginTop : ($wh / 2) * -1,
marginLeft : ($wh / 2) * -1
});
} else {
$('#main-wrapper').css({
height: $ww,
width: $ww,
marginTop : ($ww / 2) * -1,
marginLeft : ($ww / 2) * -1
});
}
});
I finally figured it out. The magic ingredients are the view-port units.
Given this html structure:
.l-table
.l-table-cell
.square
You can use this css (well actuall its scss, but you get the idea) to make it work
html,
body{
height: 100%
}
l-table{
background: orange;
display: table;
height: 100%;
width: 100%;
}
.l-table-cell{
display: table-cell;
vertical-align: middle;
border: 2px solid black;
}
.square{
background: red;
margin: auto;
#media (orientation:landscape) {
width: 70vh;
height: 70vh;
}
#media screen and (orientation:portrait) {
width: 70vw;
height: 70vw;
}
}

For those who need it, there is a polyfill.
EDIT: Since writing the below, I appealed on Twitter and got a response from Brian Johnson. He came up with a solution that isn't 100% perfect semantically, but it's pretty damn good and I'll certainly be using it. He asked that I share it in this discussion. LINK
I'm having the same issue right now and I was just typing out pretty much this exact question, so although I can't answer it, I wanted to share what I've found so far in case it helps anyone come up with the final solution.
To clarify, I need my content to fit into a square which fills 60% of the browser's width if portrait or 60% of the height if landscape.
However, this square must never exceed the width or height of the viewport.
Using the technique found here I've managed to create the fluid square, but it still exceeds the viewport when landscape.
width: 60%;
height:0;
padding-bottom: 60%;
Link to Codepen example
I have tried flipping that technique on it's side for landscape but that doesn't work. (You can see that code in the above example, noted out.)
I can't use a simple max-height property because the height is being worked out by the padding-bottom property.
I've thought about adding an extra div as someone else has suggested (C-Link's post is really interesting) but I can't work out how I'd get it to do what we want it do here.
html
<div id="outer">
<div id="inner">YOUR CONTENTS HERE
</div>
</div>
css
html, body{
height: 100%;
}
#outer{
max-height: 100%;
max-width: 100%;
position: relative;
height: 100%;
}
#inner{
position: relative;
top: 50%;
margin-top: -50% auto auto auto;
background: red;
text-align: center;
color: yellow;
}
See this fiddle.
How about if you take the earlier concept a step further with a similar div as a container. The container has an added max-height & width. I tried this and the container does not throw a scrollbar at me. It is quite interesting in behavior I must say myself. Does this work for you?
<div id="container">
<div id="centered">A DIV</div>
</div>
#container {
top:0;
bottom:0;
right:0;
left:0;
margin:auto;
position:absolute;
width:200px;
height:200px;
max-width:100%;
max-height:100%;
background:#00f;
padding:0;
}
#centered {
background: green;
bottom: 0;
height: 80px;
left: 0;
margin: auto;
position: absolute;
top: 0;
right: 0;
width: 80px;
}

CSS force image resize and keep aspect ratio

I am working with images, and I ran into a problem with aspect ratios.
<img src="big_image.jpg" width="900" height="600" alt="" />
As you can see, height and width are already specified. I added a CSS rule for images:
img {
max-width: 500px;
}
But for big_image.jpg, I receive width=500 and height=600. How do I set images to be re-sized, whilst keeping their aspect ratios.
img {
display: block;
max-width:230px;
max-height:95px;
width: auto;
height: auto;
}
<p>This image is originally 400x400 pixels, but should get resized by the CSS:</p>
<img width="400" height="400" src="http://i.stack.imgur.com/aEEkn.png">
This will make image shrink if it's too big for specified area (as downside, it will not enlarge image).
Here's a solution:
object-fit: cover;
width: 100%;
height: 250px;
You can adjust the width and height to fit your needs, and the object-fit property will do the cropping for you.
More information about the possible values for the object-fit property and a compatibility table are available here: https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit
The solutions below will allow scaling up and scaling down of the image, depending on the parent box width.
All images have a parent container with a fixed width for demonstration purposes only. In production, this will be the width of the parent box.
Best Practice (2018):
This solution tells the browser to render the image with max available width and adjust the height as a percentage of that width.
.parent {
width: 100px;
}
img {
display: block;
width: 100%;
height: auto;
}
<p>This image is originally 400x400 pixels, but should get resized by the CSS:</p>
<div class="parent">
<img width="400" height="400" src="https://placehold.it/400x400">
</div>
Fancier Solution:
With the fancier solution, you'll be able to crop the image regardless of its size and add a background color to compensate for the cropping.
.parent {
width: 100px;
}
.container {
display: block;
width: 100%;
height: auto;
position: relative;
overflow: hidden;
padding: 34.37% 0 0 0; /* 34.37% = 100 / (w / h) = 100 / (640 / 220) */
}
.container img {
display: block;
max-width: 100%;
max-height: 100%;
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
}
<p>This image is originally 640x220, but should get resized by the CSS:</p>
<div class="parent">
<div class="container">
<img width="640" height="220" src="https://placehold.it/640x220">
</div>
</div>
For the line specifying padding, you need to calculate the aspect ratio of the image, for example:
640px (w) = 100%
220px (h) = ?
640/220 = 2.909
100/2.909 = 34.37%
So, top padding = 34.37%.
Very similar to some answers here, but in my case I had images that sometimes were taller, sometimes larger.
This style worked like a charm to make sure that all images use all available space, keep the ratio and not cuts:
.img {
object-fit: contain;
max-width: 100%;
max-height: 100%;
width: auto;
height: auto;
}
The background-size property is ie>=9 only, but if that is fine with you, you can use a div with background-image and set background-size: contain:
div.image{
background-image: url("your/url/here");
background-size: contain;
background-repeat: no-repeat;
background-position: center;
}
Now you can just set your div size to whatever you want and not only will the image keep its aspect ratio it will also be centralized both vertically and horizontally within the div. Just don't forget to set the sizes on the css since divs don't have the width/height attribute on the tag itself.
This approach is different than setecs answer, using this the image area will be constant and defined by you (leaving empty spaces either horizontally or vertically depending on the div size and image aspect ratio), while setecs answer will get you a box that exactly the size of the scaled image (without empty spaces).
Edit:
According to the MDN background-size documentation you can simulate the background-size property in IE8 using a proprietary filter declaration:
Though Internet Explorer 8 doesn't support the background-size property, it is possible to emulate some of its functionality using the non-standard -ms-filter function:
-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='path_relative_to_the_HTML_file', sizingMethod='scale')";
Remove the "height" property.
<img src="big_image.jpg" width="900" alt=""/>
By specifying both you are changing the aspect ratio of the image. Just setting one will resize but preserve the aspect ratio.
Optionally, to restrict oversizings:
<img src="big_image.jpg" width="900" alt="" style="max-width:500px; height:auto; max-height:600px;"/>
Firefox 71+ (2019-12-03) and Chrome 79+ (2019-12-10) support internal mapping of the width and height HTML attributes of the IMG element to the new aspect-ratio CSS property (the property itself is not yet available for direct use).
The calculated aspect ratio is used to reserve space for the image until it is loaded, and as long as the calculated aspect ratio is equal to the actual aspect ratio of the image, page “jump” is prevented after loading the image.
For this to work, one of the two image dimensions must be overridden via CSS to the auto value:
IMG {max-width: 100%; height: auto; }
<img src="example.png" width="1280" height="720" alt="Example" />
In the example, the aspect ratio of 16:9 (1280:720) is maintained even if the image is not yet loaded and the effective image width is less than 1280 as a result of max-width: 100%.
See also the related Firefox bug 392261.
Here is a solution :
img {
width: 100%;
height: auto;
object-fit: cover;
}
This will make sure the image always covers the entire parent (scaling down and up) and keeps the same aspect ratio.
Just add this to your css, It will automaticly shrink and expand with keeping the original ratio.
img {
display: block;
max-width: 100%;
max-height: 100%;
width: auto;
height: auto;
}
This is mental. Use the scale-down property - it explains itself.
Inline styling:
<img src='/nic-cage.png' style={{ maxWidth: '50%', objectFit: 'scale-down' }} />
This will stop flex from stretching it. In this case, the image would go to 50% of the width of its parent container and the height would scale down to match.
Keep it simple.
Just replace the height attribute by the aspect-ratio attribute.
img {
max-width: 500px;
aspect-ratio: 900 / 600;
}
<img src="big_image.png" width="900"/>
The aspect-ratio attribute is not necessary, but prevent image layout shifts.
To maintain a responsive image while still enforcing the image to have a certain aspect ratio you can do the following:
HTML:
<div class="ratio2-1">
<img src="../image.png" alt="image">
</div>
And SCSS:
.ratio2-1 {
overflow: hidden;
position: relative;
&:before {
content: '';
display: block;
padding-top: 50%; // ratio 2:1
}
img {
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
}
}
This can be used to enforce a certain aspect ratio, regardless of the size of the image that authors upload.
Thanks to #Kseso at http://codepen.io/Kseso/pen/bfdhg. Check this URL for more ratios and a working example.
Set the CSS class of your image container tag to image-class:
<div class="image-full"></div>
and add this you your CSS stylesheet.
.image-full {
background: url(...some image...) no-repeat;
background-size: cover;
background-position: center center;
}
I would suggest for a responsive approach the best practice would be using the Viewport units and min/max attributes as follows:
img{
display: block;
width: 12vw;
height:12vw;
max-width:100%;
min-width:100px;
min-height:100px;
object-fit:contain;
}
To force image that fit in a exact size, you don't need to write too many codes. It's so simple
img{
width: 200px;
height: auto;
object-fit: contain; /* Fit logo in the image size */
-o-object-fit: contain; /* Fit logo fro opera browser */
object-position: top; /* Set logo position */
-o-object-position: top; /* Logo position for opera browser */
}

Here is the answer if you want to put image with fixed percentage of width, but not fixed pixel of width.
And this will be useful when dealing with different size of screen.
The tricks are
Using padding-top to set the height from width.
Using position: absolute to put image in the padding space.
Using max-height and max-width to make sure the image will not over the parent element.
using display:block and margin: auto to center the image.
I've also comment most of the tricks inside the fiddle.
I also find some other ways to make this happen.
There will be no real image in html, so I personly perfer the top answer when I need "img" element in html.
simple css by using background
http://jsfiddle.net/4660s79h/2/
background-image with word on top
http://jsfiddle.net/4660s79h/1/
the concept to use position absolute is from here
http://www.w3schools.com/howto/howto_css_aspect_ratio.asp
You can use this:
img {
width: 500px;
height: 600px;
object-fit: contain;
position: relative;
top: 50%;
transform: translateY(-50%);
}
You can create a div like this:
<div class="image" style="background-image:url('/to/your/image')"></div>
And use this css to style it:
height: 100%;
width: 100%;
background-position: center center;
background-repeat: no-repeat;
background-size: contain; // this can also be cover
You can set the container to display: flex and align-items: center (other align-items values work too). Instead of align-items you can also set align-self on the image itself.
This will make image shrink if it's too big for specified area (as downside, it will not enlarge image).
The solution by setec is fine for "Shrink to Fit" in auto mode.
But, to optimally EXPAND to fit in 'auto' mode, you need to first put the received image into a temp id,
Check if it can be expanded in height or in width (depending upon its aspect ration v/s the aspect ratio of your display block),
$(".temp_image").attr("src","str.jpg" ).load(function() {
// callback to get actual size of received image
// define to expand image in Height
if(($(".temp_image").height() / $(".temp_image").width()) > display_aspect_ratio ) {
$(".image").css('height', max_height_of_box);
$(".image").css('width',' auto');
} else {
// define to expand image in Width
$(".image").css('width' ,max_width_of_box);
$(".image").css('height','auto');
}
//Finally put the image to Completely Fill the display area while maintaining aspect ratio.
$(".image").attr("src","str.jpg");
});
This approach is useful when received images are smaller than display box. You must save them on your server in Original Small size rather than their expanded version to fill your Bigger display Box to save on size and bandwidth.
You Can use:-
transform: scaleX(1.2);
to change the width without changing height.
And
transform: scaleY(1.2);
to change the height without changing width
You can use this on images and video tags in html and css. This does not change the aspect ration also.
you can use aspect-ratio property css
.my-image {
aspect-ratio: 1/1; // square
aspect-ratio: 16/9; // wide screen 1080p
aspect-ratio: 4/3;
aspect-ratio: 2/3;
}
img {
max-width: 80px; /* Also works with percentage value like 100% */
height: auto;
}
<p>This image is originally 400x400 pixels, but should get resized by the CSS:</p>
<img width="400" height="400" src="https://i.stack.imgur.com/aEEkn.png">
<p>Let's say the author of the HTML deliberately wants
the height to be half the value of the width,
this CSS will ignore the HTML author's wishes, which may or may not be what you want:
</p>
<img width="400" height="200" src="https://i.stack.imgur.com/aEEkn.png">
How about using a pseudo element for vertical alignment? This less code is for a carousel but i guess it works on every fixed size container. It will keep the aspect ratio and insert #gray-dark bars on top/bottom or left/write for the shortest dimension. In the meanwhile the image is centered horizontally by the text-align and vertically by the pseudo element.
> li {
float: left;
overflow: hidden;
background-color: #gray-dark;
text-align: center;
> a img,
> img {
display: inline-block;
max-height: 100%;
max-width: 100%;
width: auto;
height: auto;
margin: auto;
text-align: center;
}
// Add pseudo element for vertical alignment of inline (img)
&:before {
content: "";
height: 100%;
display: inline-block;
vertical-align: middle;
}
}
Fullscreen presentation:
img[data-attribute] {height: 100vh;}
Keep in mind that if the view-port height is greater than the image the image will naturally degrade relative to the difference.
If the application can have an image of any aspect ratio or resolution then you can manage height and width as in this link.
