I have a container that will grow/shrink in height based on how much text is dynamically placed inside it. The container will have a background image that needs to stretch/shrink as the container changes height and this image cannot be cropped in any way. I am wondering how would I style .container to get the background-image to be stay 100% of the div.
I have tried the following, but it didn't seem to work:
.container { background: url('backgroundImage.jpg') 0 100% no-repeat; }
Sample of HTML Structure:
<div class="container">
<p class="text">This is a short container</p>
</div>
<div class="container">
<p class="text">This<br> is<br> a<br> tall<br> container</p>
</div>
You need to set the background-size property.
background-size: 100% 100%; will scale it to fill the container both horizontally and vertically.
I usually prefer background-size: cover; as it gracefully scales up the image as needed, maintaining the aspect ratio. Make sure to check the support for background-size, as it is a fairly new property.
In case background-size: contain; is not helpful and if you are looking for full HEIGHT background image without loosing aspect ratio then use below written CSS
background-size: auto 100%;
setting first parameter to "auto" will ensure that image keep width in ratio of current height. Second parameter which is "100%" will help background image adapt same height as DIV.
Did you try background-size: cover; ?
In your example you're adjusting background-position.
There is a property in css3 called as background-size:cover; and background-size:contain;. You might want to use background-size:cover; to suit your needs.
**contain
Specifies that the background image should be scaled to be as large as
possible while ensuring both its dimensions are less than or equal to
the corresponding dimensions of the background positioning area.
cover
Specifies that the background image should be scaled to be as small as
possible while ensuring both its dimensions are greater than or equal
to the corresponding dimensions of the background positioning area.

When I place a background image in my div to create a background for it a scrollbar horizontally for the whole webpage. I think it is because my background-size: cover; made the background image grow to its original size but I want the image to scale down exactly to fit all devices.
Codepen: https://codepen.io/Javscript/pen/WNXmRMp?editors=1100
The scrollbar has nothing to do with the background image, not even with the element which has the background image. (Btw., a background image can never affect box sizing.)
The .main-con element has a width of 100% and a margin of 160px. The 100% does not refer to the remaining space; it refers to the width of the parent element, in this case the body.
So the .main-con element is as big as the body/screen, but has a 160px distance from the left side, resulting in it overflowing 160px on the right side.
One way to counteract this without completly reimplementing your website would be to set the width of the .main-con element to calc(100% - 160px).
Try to use this property:
background-size: contain;
background-repeat: no-repeat;;
The difference between the values cover and contain is that:
1- cover: makes the background covers the whole div
2- size: makes the background fits inside the div
You gave your background Image a size of 100%. But you have allso ur Sidebar. So the Image itself cant take all 100% of the screen. Try using
calc(100% - 160px)
for the with of the .main-con
Is there a way, using solely CSS, to set an image's height to its container's height, while maintaining aspect ratio, allowing the width to overflow and be hidden? That sounds like a lot of requirements, but surely there's a way. What I mean is, I want the full height of the image to be displayed, but if the width is wider than the container allows (using bootstraps grid system), then just overflow: hidden. I have the height set to 100% which looks good, but the picture squishes in from the sides to fit inside the container rather than overflowing and being cropped. By setting width to 100%, it's filling the container. I believe it's using the container as the standard for the 100%, rather than the aspect ratio of the photo. So that's what I need to do.
This is what I have going on:
<div style="width:150px; height:150px; display:flex; flex-direction:column">
<img src="http://i.imgur.com/RiX7XfW.jpg" alt="Banana" style="height:100%;width:auto;overflow:hidden">
</div>
TL;DR I need to maintain aspect ration of an image, lock the height to the container height and let the excess of the picture just overflow and be hidden, allowing me to see the maximum amount of the picture possible, while still filling the container.
Bonus points if there's a way to somehow calculate which dimension is smaller and lock that one to the relevant container dimension.
Not so easy to do this if using an image tag, but if using the CSS background-image property (or the shortcut background), then
#wrap{width:300px;height:200px;margin:50px;overflow:hidden;}
#imgDiv{width:1000px;height:1000px;background-image:url(http://placekitten.com/900/900); background-size:cover;}
<div id="wrap">
<div id="imgDiv">
</div>
</div>
Are you suggesting overflow: hidden in the CSS? It's a routine default measure, and you speak around it, like you might be recalling the measure.
Not setting a height, and setting width: 100%, is a nice way to regard the aspect ratio with more concern to the full width. So height: 100% without a specification for width may be a best way to keep full height with aspect ratio intact.
Instead of embedding the image with an img tag, you can set the image as the background image of the container. Then by using a combination of background-size:cover; and background-position:center center; you can cause the image to match the height of the container while keeping the aspect ratio of the original image. The background-position property will center the image so that the left and right sides are cropped off.
Using shorthand, that code would look like this:
<div style="background:url('http://i.imgur.com/RiX7XfW.jpg') center center / cover no-repeat; width:150px; height:150px; display:flex; flex-direction:column"></div>
I would like a div with a background-image that keeps the aspect ratio of the image, with a fixed height of 500px and i want no "padding" on the background of that div.
Is this possible to do?
I Can get a div with a fixed height and a background-image that keeps aspect ratio :
<div style="background: url(something.png) 50% 50% / cover #D6D6D6;background-size: contain;background-repeat: no-repeat;height:500px"></div>
This makes the image centered in the middle of the div ( either vertically or horizontally ) but gives some padding to the background of the div ...
Can anybody help me out ?
What you are trying to achieve is not possible using only CSS, you could use JavaScript to detect the width of the image and then set the width of the div to be the same. Or alternatively you could simply remove the background-image property and rather add the image as an img tag into your HTML. If you do that you can display the div as inline-block which will take care of making the div as wide as the width of the image.
body
{
text-align:center;
}
div
{
background-color:#666;
display:inline-block;
}
div img
{
height:500px;
}
<div>
<img src="http://lorempixel.com/200/500" alt="">
</div>
background-size: contain; will always display the whole image (without cutting off anything), thereby leaving some space either vertically or horizontally.
On the other hand, background-size: cover; will fill the whole DIV in a way that the shorter side of the image corresponds exactly to the length or height of the DIV (depending on the relation of the proportions between DIV and image) and the longer one is cut off on the sides or on top and bottom.
If you don't want a distorted image, those are the options you have.
I'm trying to fill a whole div with an image, regardless of the size of the image, but for some reason the image is only as big as it's default size. It does not automatically stretch to fit the size of the div. I tried setting the width and height of the image to 100%, thinking that it'll fit the div that way, but the image still stayed in its default size. Is there a way to automatically stretch an image to fill a div, without testing and changing each image by hand?
<style>
div {
border: 1px solid red;
width: 1000px;
height: 1000px;
background-image: url("side.jpg");
background-repeat: no-repeat;
}
img {
width: 100%;
height: 100%;
}
</style>
<div> </div>
From your question, it is unclear whether you are trying to use a background image or an img element to fill the div.
If you want to fill the div using an img element, the code you've posted will already do that for you. You just need to place an img element within the div, such as:
<div><img src="http://placehold.it/250x250" /></div>
If you want to stretch the image to fill the div using it as a background image, you simply need to add the value cover to the background-size property:
background-size:cover;

The <img> tag is an html element that has nothing to do with the background image of that <div>.
As APAD1 correctly points out, the proper way to force a background image to fill an html element is to use background-size.
background-size: contain fills the element until the background image touches the first edge of its container (maintaining the aspect ratio).
background-size: cover fills the element entirely while maintaining the aspect ratio of the image.
background-size: 100% 100% fills the element entirely so that the background image touches the edge of the element on all sides (thus potentially distorting the image).
I have a wrapper div that contains arbitrary content (I don't know its length). How can I put a background image that stretches its whole length since background-images doesn't stretch?
I've tried with a div containing a img tag. The div has a lover z-index that the rest of the content and has position: absolute. The problem is that the image is longer that the content and so it just makes it longer (the wrapper has overflow: auto).
<div id="wrapper">
<div id="image-wrapper" style="position: absolute"><img src="bg.jpg"></div>
[.. OTHER CONTENT ..]
</div>
If I set the div and the image's width and height to 100%, it takes the window's height, not the wrapper's.
Any help?
background-size is available since CSS3:
#image {
background-image: url("bg.png");
background-size: auto;
}
auto is the default value and does not stretch the image.
You can set the width and height manually:
#image {
background-size: 100% 100%;
}
or
#image {
background-size: 500px 300px;
}
The alternative: background-size: contain and background-size: cover.
contain stretches the image so that the image is as big as possible but completely visible within the element, whereas cover stretches the image to 100% width, regardless if the image is cropped at the top and/or the bottom.
But the different browsers are not completely consistent when rendering backgrounds with these keywords.
If you are willing to use JavaScript, check out Supersized. It seems to work well for this particular case.
you might also try html5 method on image.
#image-wrapper img {max-width: 100%}
Add position: relative to the styles for #wrapper.
