Here is a solution that will both vertically and horizontally align your img within a div without any stretching even if the image supplied is too small or too big to fit in the div.
The HTML content:
<div id="myDiv">
<img alt="Client Logo" title="Client Logo" src="Imagelocation" />
</div>
The CSS content:
#myDiv
{
height: 104px;
width: 140px;
}
#myDiv img
{
max-width: 100%;
max-height: 100%;
margin: auto;
display: block;
}
The jQuery part:
var logoHeight = $('#myDiv img').height();
if (logoHeight < 104) {
var margintop = (104 - logoHeight) / 2;
$('#myDiv img').css('margin-top', margintop);
}How to auto-resize an image to fit a ‘div’ container?
Do not apply an explicit width or height to the image tag. Instead, give it:
max-width:100%;
max-height:100%;
Also, height: auto; if you want to specify a width only.
img {
max-width: 100%;
max-height: 100%;
}
.portrait {
height: 80px;
width: 30px;
}
.landscape {
height: 30px;
width: 80px;
}
.square {
height: 75px;
width: 75px;
}Portrait Div
<div class="portrait">
<img src="http://i.stack.imgur.com/xkF9Q.jpg">
</div>
Landscape Div
<div class="landscape">
<img src="http://i.stack.imgur.com/xkF9Q.jpg">
</div>
Square Div

It turns out there’s another way to do this.
<img style='height: 100%; width: 100%; object-fit: contain'/>
will do the work. It’s CSS 3 stuff.
Answer #4:
Currently there is no way to do this correctly in a deterministic way, with fixed-size images such as JPEGs or PNG files.
To resize an image proportionally, you have to set either the height or width to “100%”, but not both. If you set both to “100%”, your image will be stretched.
Choosing whether to do height or width depends on your image and container dimensions:
- If your image and container are both “portrait shaped” or both “landscape shaped” (taller than they are wide, or wider than they are tall, respectively), then it doesn’t matter which of height or width are “%100”.
- If your image is portrait, and your container is landscape, you must set
height="100%"on the image. - If your image is landscape, and your container is portrait, you must set
width="100%"on the image.
If your image is an SVG, which is a variable-sized vector image format, you can have the expansion to fit the container happen automatically.
You just have to ensure that the SVG file has none of these properties set in the <svg> tag:
height
width
viewbox
Most vector drawing programs out there will set these properties when exporting an SVG file, so you will have to manually edit your file every time you export or write a script to do it.
Answer #5:
You have two ways of making the image responsive.
1). When an image is a background image.
#container{
width: 300px;
height: 300px;
background-image: url(https://images.fonearena.com/blog/wp-content/uploads/2013/11/Lenovo-p780-camera-sample-10.jpg);
background-size: cover;
background-repeat: no-repeat;
background-position: center;
}
<div id="container"><div>But one should use img tag to put images as it is better than background-image in terms of SEO as you can write keyword in the alt of the img tag. So here is you can make the image responsive.
2). When image is in img tag.
#container{
max-width: 400px;
overflow: hidden;
}
img{
width: 100%;
object-fit: contain;
}
<div id="container">
<img src="https://images.fonearena.com/blog/wp-content/uploads/2013/11/Lenovo-p780-camera-sample-10.jpg" alt="your_keyword"/>
<div>Answer #6:
Make it simple!
Give the container a fixed height and then for the img tag inside it, set width and max-height.
<div style="height: 250px">
<img src="..." alt=" " style="width: 100%;max-height: 100%" />
</div>
The difference is that you set the width to be 100%, not the max-width.
How to auto-resize an image to fit a ‘div’ container using CSS?
It’s written in pure CSS, without any JavaScript code. It can handle images of any size and any orientation.
Given such HTML:
<div class="image">
<div class="trick"></div>
<img src="http://placekitten.com/415/200"/>
</div>
the CSS code would be:
.image {
font-size: 0;
text-align: center;
width: 200px; /* Container's dimensions */
height: 150px;
}
img {
display: inline-block;
vertical-align: middle;
max-height: 100%;
max-width: 100%;
}
.trick {
display: inline-block;
vertical-align: middle;
height: 150px;
}Answer #8:
There are several ways to fit the image to <div>.
img {
object-fit: cover;
}
The CSS object-fit property is used to specify how an <img> or <video> should be resized to fit its container.
This property tells the content to fill the container in a variety of ways; such as “preserve that aspect ratio” or “stretch up and take up as much space as possible”.
- fill – This is default. The image is resized to fill the given dimension. If necessary, the image will be stretched or squished to fit
- contain – The image keeps its aspect ratio, but is resized to fit within the given dimension
- cover – The image keeps its aspect ratio and fills the given dimension. The image will be clipped to fit
- none – The image is not resized
- scale-down – the image is scaled down to the smallest version of none or contain
Solution #9:
I have a much better solution without the need for any JavaScript. It is fully responsive, and I use it a lot. You often need to fit an image of any aspect ratio to a container element with a specified aspect ratio. And having whole this thing fully responsive is a must.
/* For this demo only */
.container {
max-width: 300px;
margin: 0 auto;
}
.img-frame {
box-shadow: 3px 3px 6px rgba(0, 0, 0, .15);
background: #ee0;
margin: 20px auto;
}
/* This is for responsive container with specified aspect ratio */
.aspect-ratio {
position: relative;
}
.aspect-ratio-1-1 {
padding-bottom: 100%;
}
.aspect-ratio-4-3 {
padding-bottom: 75%;
}
.aspect-ratio-16-9 {
padding-bottom: 56.25%;
}
/* This is the key part - position and fit the image to the container */
.fit-img {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
margin: auto;
max-width: 80%;
max-height: 90%
}
.fit-img-bottom {
top: auto;
}
.fit-img-tight {
max-width: 100%;
max-height: 100%
}<div class="container">
<div class="aspect-ratio aspect-ratio-1-1 img-frame">
<img src="https://via.placeholder.com/400x300" class="fit-img" alt="sample">
</div>
<div class="aspect-ratio aspect-ratio-4-3 img-frame">
<img src="https://via.placeholder.com/400x300" class="fit-img fit-img-tight" alt="sample">
</div>
<div class="aspect-ratio aspect-ratio-16-9 img-frame">
<img src="https://via.placeholder.com/400x400" class="fit-img" alt="sample">
</div>
<div class="aspect-ratio aspect-ratio-16-9 img-frame">
<img src="https://via.placeholder.com/300x400" class="fit-img fit-img-bottom" alt="sample">
</div>
</div>You can set max-width and max-height independently; the image will respect the smallest one (depending on the values and aspect ratio of the image). You can also set the image to be aligned as you want (for example, for a product picture on an infinite white background you can position it to the center bottom easily).
Answer #10:
This solution doesn’t stretch the image and fills the whole container, but it cuts some of the image.
HTML:
<div><img src="/images/image.png"></div>
CSS:
div {
width: 100%;
height: 10em;
overflow: hidden;
img {
min-width: 100%;
min-height: 100%;
}Answer #11:
I see that many people have suggested object-fit which is a good option. But if you want it to work in older browsers as well, there is another way of doing it easily.
It’s quite simple. The approach I took was to position the image inside the container with absolute and then place it right at the centre using the combination:
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
Once it is in the centre, I give to the image,
// For vertical blocks (i.e., where height is greater than width)
height: 100%;
width: auto;
// For horizontal blocks (i.e., where width is greater than height)
height: auto;
width: 100%;
This makes the image get the effect of object-fit:cover.
This logic works in all browsers.
