I want the content inside of my div to scale with the browser vertically to prevent the need for scrolling The images will be different orientations so the width will be different. I know this can be achieved horizontally with width:100%; but max-height:100%; or height:auto; both still extend past the browser window for me and I'm not sure why.
EDIT: Had a lot of additional modal code in here, and simplified it down to the html/css and switched from simple width:100% height: 100% to vh and vw.

What's happening:
How I want it to look:
<body>
<style>
.modal {
display: block;
position: fixed;
z-index: 1;
box-sizing:border-box;
left: 0;
top: 0;
height: 100%;
width:100%;
overflow:auto;
background-color:#D81E21;
}
.modal-content {
position: relative;/*modal x button */
width: auto;
height: auto;
background-color: #7E7DE1;
max-height: 50vh;
max-width:70vw;
margin: auto;
}
.mySlides{
max-height:100%;
max-width: 100%;
height:auto;
width:auto;
}
.roll-img {
display:flex;
flex-wrap:wrap;
}
.column {
flex:1;
}
.caption-container {
text-align: center;
background-color: black;
padding: 2px 16px;
color: white;
}
</style>
<div id="myModal" class="modal">
<div class="modal-content">
<div class="mySlides">
<img src="images/5_2.jpg">
</div>
<div class="caption-container">
<p id="caption"></p>
</div>
<div class="roll-img">
<div class="column">
<img class="demo cursor" src="images/5_2.jpg">
</div>
</div> <!--roll-img-->
</div> <!--modal-content-->
</div> <!--myModal-->
</body>
As your .modal-content width is 30%. it might help
.modal-content .mySlides img {
position: relative;
width: 100%;
height: auto;
}
to fit image in 30% width of model content
Try using
min-height: 100vh;
vh refers to the viewport height.
I am able to get the desired result by applying 4 things:
max-width: 90vw; ensures that the object will never exceed 90% of the screen width.
max-height: 90vh; ensures that the object will never exceed 90% of the screen height.
width: auto; adjusts the width to maintain the original aspect ratio
height: auto; adjusts the width to maintain the original aspect ratio
With these four combined, the object will always be fully in view and you will not need to scroll the screen.
Working example:
(open in full screen and resize vertically or horizontally to see the effect)
body {
background: #131418;
margin: auto;
padding: 0;
text-align: center;
}
.adjust {
width: auto;
height: auto;
max-width: 90vw;
max-height: 90vh;
margin: 0 auto;
}
<img class="adjust" src="https://unsplash.it/3000/3000">
As you can see in the picture below, my logo/banner is overlapping the body of my site when I zoom in using any browser. It continues to overflow the farther you zoom in.
What would be the best way to keep the banner the same width as the body even after zooming occurs?
HTML:
<div class="container1"> <div class="header"><img src="images/banner test.jpg" alt="logo" />
CSS:
.container1 {
width: 80%;
max-width: 1260px;
min-width: 780px;
margin: 0 auto;
}
.header {
max-width: 900px;
margin: 0 auto;
}

Thanks a lot in advance.
Add overflow to your div
.header {
max-width: 900px;
margin: 0 auto;
overflow: hidden;
}
I have a header image that stopped resizing after I placed it in a CSS wrapper. I specified the width of the wrapper, b/c I want the navigation to the right to be directly above the white space area below - flushed to the right.
How can I set the width of the wrapper in which I place an image but maintain the responsiveness (image responds to resizing)?
HERE's the URL; http://www.insidemarketblog.com/
Here's the code:
HTML
<div id="header">
<div class="wrap">
<span class="menu_control">≡ Menu</span>
<ul class="nav"><li class="page_item page-item-35">ABOUT US</li></ul>
<h1 id="site_title"><a href="http://www.insidemarketblog.com"><img id="thesis_logo_image" src="http://www.insidemarketblog.com/wp-content/uploads/2014/03/logo_header1.png" alt="Inside Market Strategy" width="400" height="87" title="click to go home" />
</a></h1>
</div>
</div>
CSS:
.wrap {
width: 1000px;
margin: 0 auto;
border: 1px solid #000;
position: relative;
}
You need to make the image flex too:
img {
display: block;
width: 100%;
height: auto;
}
I believe you have two issues here:
1st, Your .wrap is 1000px in width. please make it 100%
2nd, your img css should have a max-width: 400px; and width:100%
This way you will have your img exactly the way you want it.
Here is the css:
.wrap {
width: 100%;
margin: 0 auto;
border: 1px solid #000;
position: relative;
}
img {
width: 100%;
max-width: 400px;
height: auto;
}

Is there a css-only solution to scale an image into a bounding box (keeping aspect-ratio)? This works if the image is bigger than the container:
img {
max-width: 100%;
max-height: 100%;
}
Example:
Use case 1 (works): http://jsfiddle.net/Jp5AQ/2/
Use case 2 (works): http://jsfiddle.net/Jp5AQ/3/
But I want to scale up the image until a dimension is 100% of the container.
Use case 3 (doesn't work): http://jsfiddle.net/Jp5AQ/4/
Thanks to CSS3 there is a solution !
The solution is to put the image as background-image and then set the background-size to contain.
HTML
<div class='bounding-box'>
</div>
CSS
.bounding-box {
background-image: url(...);
background-repeat: no-repeat;
background-size: contain;
}
Test it here: http://www.w3schools.com/cssref/playit.asp?filename=playcss_background-size&preval=contain
Full compatibility with latest browsers: http://caniuse.com/background-img-opts
To align the div in the center, you can use this variation:
.bounding-box {
background-image: url(...);
background-size: contain;
position: absolute;
background-position: center;
background-repeat: no-repeat;
height: 100%;
width: 100%;
}
Note: Even though this is the accepted answer, the answer below is more accurate and is currently supported in all browsers if you have the option of using a background image.
Edit 2: In the modern age, using object-fit might be an even better solution: https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit
No, there is no CSS only way to do this in both directions. You could add
.fillwidth {
min-width: 100%;
height: auto;
}
To the an element to always have it 100% width and automatically scale the height to the aspect ratio, or the inverse:
.fillheight {
min-height: 100%;
width: auto;
}
to always scale to max height and relative width. To do both, you will need to determine if the aspect ratio is higher or lower than it's container, and CSS can't do this.
The reason is that CSS does not know what the page looks like. It sets rules beforehand, but only after that it is that the elements get rendered and you know exactly what sizes and ratios you're dealing with. The only way to detect that is with JavaScript.
Although you're not looking for a JS solution I'll add one anyway if someone might need it. The easiest way to handle this with JavaScript is to add a class based on the difference in ratio. If the width-to-height ratio of the box is greater than that of the image, add the class "fillwidth", else add the class "fillheight".
$('div').each(function() {
var fillClass = ($(this).height() > $(this).width())
? 'fillheight'
: 'fillwidth';
$(this).find('img').addClass(fillClass);
});
.fillwidth {
width: 100%;
height: auto;
}
.fillheight {
height: 100%;
width: auto;
}
div {
border: 1px solid black;
overflow: hidden;
}
.tower {
width: 100px;
height: 200px;
}
.trailer {
width: 200px;
height: 100px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="tower">
<img src="http://placekitten.com/150/150" />
</div>
<div class="trailer">
<img src="http://placekitten.com/150/150" />
</div>
Here's a hackish solution I discovered:
#image {
max-width: 10%;
max-height: 10%;
transform: scale(10);
}
This will enlarge the image tenfold, but restrict it to 10% of its final size - thus bounding it to the container.
Unlike the background-image solution, this will also work with <video> elements.
Interactive example:
function step(timestamp) {
var container = document.getElementById('container');
timestamp /= 1000;
container.style.left = (200 + 100 * Math.sin(timestamp * 1.0)) + 'px';
container.style.top = (200 + 100 * Math.sin(timestamp * 1.1)) + 'px';
container.style.width = (500 + 500 * Math.sin(timestamp * 1.2)) + 'px';
container.style.height = (500 + 500 * Math.sin(timestamp * 1.3)) + 'px';
window.requestAnimationFrame(step);
}
window.requestAnimationFrame(step);
#container {
outline: 1px solid black;
position: relative;
background-color: red;
}
#image {
display: block;
max-width: 10%;
max-height: 10%;
transform-origin: 0 0;
transform: scale(10);
}
<div id="container">
<img id="image" src="https://upload.wikimedia.org/wikipedia/en/7/7d/Lenna_%28test_image%29.png">
</div>
Today, just say object-fit: contain. Support is everything but IE: http://caniuse.com/#feat=object-fit
html:
<div class="container">
<img class="flowerImg" src="flower.jpg">
</div>
css:
.container{
width: 100px;
height: 100px;
}
.flowerImg{
width: 100px;
height: 100px;
object-fit: cover;
/*object-fit: contain;
object-fit: scale-down;
object-position: -10% 0;
object-fit: none;
object-fit: fill;*/
}
You can accomplish this with pure CSS and complete browser support, both for vertically-long and horizontally-long images at the same time.
Here's a snippet which works in Chrome, Firefox, and Safari (both using object-fit: scale-down, and without using it):
figure {
margin: 0;
}
.container {
display: table-cell;
vertical-align: middle;
width: 80px;
height: 80px;
border: 1px solid #aaa;
}
.container_image {
display: block;
max-width: 100%;
max-height: 100%;
margin-left: auto;
margin-right: auto;
}
.container2_image2 {
width: 80px;
height: 80px;
object-fit: scale-down;
border: 1px solid #aaa;
}
Without `object-fit: scale-down`:
<br>
<br>
<figure class="container">
<img class="container_image" src="https://i.imgur.com/EQgexUd.jpg">
</figure>
<br>
<figure class="container">
<img class="container_image" src="https://i.imgur.com/ptO8pGi.jpg">
</figure>
<br> Using `object-fit: scale-down`:
<br>
<br>
<figure>
<img class="container2_image2" src="https://i.imgur.com/EQgexUd.jpg">
</figure>
<br>
<figure>
<img class="container2_image2" src="https://i.imgur.com/ptO8pGi.jpg">
</figure>
Another solution without background image and without the need for a container (though the max sizes of the bounding box must be known):
img{
max-height: 100px;
max-width: 100px;
width: auto; /* These two are added only for clarity, */
height: auto; /* as the default is auto anyway */
}
If a container's use is required, then the max-width and max-height can be set to 100%:
img {
max-height: 100%;
max-width: 100%;
width: auto; /* These two are added only for clarity, */
height: auto; /* as the default is auto anyway */
}
div.container {
width: 100px;
height: 100px;
}
For this you would have something like:
<table>
<tr>
<td>Lorem</td>
<td>Ipsum<br />dolor</td>
<td>
<div class="container"><img src="image5.png" /></div>
</td>
</tr>
</table>
This example to stretch the image proportionally to fit the entire window.
An improvisation to the above correct code is to add $( window ).resize(function(){});
function stretchImg(){
$('div').each(function() {
($(this).height() > $(this).find('img').height())
? $(this).find('img').removeClass('fillwidth').addClass('fillheight')
: '';
($(this).width() > $(this).find('img').width())
? $(this).find('img').removeClass('fillheight').addClass('fillwidth')
: '';
});
}
stretchImg();
$( window ).resize(function() {
strechImg();
});
There are two if conditions. The first one keeps checking if the image height is less than the div and applies .fillheight class while the next checks for width and applies .fillwidth class.
In both cases the other class is removed using .removeClass()
Here is the CSS
.fillwidth {
width: 100%;
max-width: none;
height: auto;
}
.fillheight {
height: 100vh;
max-width: none;
width: auto;
}
You can replace 100vh by 100% if you want to stretch the image with in a div. This example to stretch the image proportionally to fit the entire window.
Are you looking to scale upwards but not downwards?
div {
border: solid 1px green;
width: 60px;
height: 70px;
}
div img {
width: 100%;
height: 100%;
min-height: 500px;
min-width: 500px;
outline: solid 1px red;
}
This however, does not lock aspect-ratio.
I have used table to center image inside the box. It keeps aspect ratio and scales image in a way that is totally inside the box. If the image is smaller than the box then it is shown as it is in the center. Below code uses 40px width and 40px height box. (Not quite sure how well it works because I removed it from another more complex code and simplified it little bit)
.SmallThumbnailContainer {
display: inline-block;
position: relative;
float: left;
width: 40px;
height: 40px;
border: 1px solid #ccc;
margin: 0px;
padding: 0px;
}
.SmallThumbnailContainer {
width: 40px;
margin: 0px 10px 0px 0px;
}
.SmallThumbnailContainer tr {
height: 40px;
text-align: center;
}
.SmallThumbnailContainer tr td {
vertical-align: middle;
position: relative;
width: 40px;
}
.SmallThumbnailContainer tr td img {
overflow: hidden;
max-height: 40px;
max-width: 40px;
vertical-align: middle;
margin: -1px -1px 1px -1px;
}
<table class="SmallThumbnailContainer" cellpadding="0" cellspacing="0">
<tr>
<td>
<img src="https://www.gravatar.com/avatar/bf7d39f4ed9c289feca7de38a0093250?s=32&d=identicon&r=PG" width="32" height="32" alt="OP's SO avatar image used as a sample jpg because it is hosted on SO, thus always available" />
</td>
</tr>
</table>
Note: the native thumbnail size in this snippet is 32px x 32px, which is smaller than its 40px x 40px container. If the container is instead sized smaller than the thumbnail in any dimension, say 40px x 20px, the image flows outside the container in the dimensions that are smaller than the corresponding image dimension. The container is marked by a gray 1px border.
Use Object Fit on both div and img to scale image
<div class="box"><img src="image.jpg"></div>
.box {height: auto;
object-fit: cover;}
img { height: 100%; object-fit: cover; }
This worked for my needs, doesn't flatten out the image while setting height limitation, it overflows instead.
.top-container{
width:50%;
}
.img-container {
display: flex;
justify-content: center;
align-items: center;
height: 40vh;
width: 100%;
overflow: hidden;
}
.img-container img {
max-width: 10%;
max-height: auto;
transform: scale(10);
}
<div class='top-container'>
<div class='img-container'>
<img src='image.jpg'>
</div>
</div>
First some CSS:
div.image-wrapper {
height: 230px; /* Suggestive number; pick your own height as desired */
position: relative;
overflow: hidden; /* This will do the magic */
width: 300px; /* Pick an appropriate width as desired, unless you already use a grid, in that case use 100% */
}
img {
width: 100%;
position: absolute;
left: 0;
top: 0;
height: auto;
}
The HTML:
<div class="image-wrapper">
<img src="yourSource.jpg">
</div>
.img-class {
width: <img width>;
height: <img height>;
content: url('/path/to/img.png');
}
Then on the element (you can use javascript or media queries to add responsiveness):
<div class='img-class' style='transform: scale(X);'></div>
.boundingbox {
width: 400px;
height: 500px;
border: 2px solid #F63;
}
img{
width:400px;
max-height: 500px;
height:auto;
}
With the styles set as shown above in css, now the following html div will show the image always fit width wise and will adjust hight aspect ratio to width. Thus image will scale to fit a bounding box as asked in the question.
<div class="boundingbox"><img src="image.jpg"/></div>
I want to have a login form centred on the page. An example is here
I know how to centre an element what I can't work out is how to centre an element always in the centre of the page even if the browser window changes size
Classic problem. Here's some example CSS:
#your_element{
position: fixed;
left: 50%;
top: 50%;
width: 600px;
height: 400px;
margin-left: -300px;
margin-top: -200px;
}
Important bit: the negative margins should be half of the respective dimensions.
Add position: fixed; to it's style. If you know how to center it, then just adding this should do the trick.
Have a look here for more info: http://www.w3.org/TR/CSS2/visuren.html#choose-position
I keep this template HTML just for this situation, when I need a container that is vertically and horizontally centered:
CSS:
html, body {
height: 100%;
}
body {
background: #ffc;
margin: 0;
padding: 0;
}
#vertical-center {
float: left;
height: 50%;
width: 100%;
margin-top: -185px;
}
#content {
background: #ffffde;
border: 2px dashed red;
clear: both;
margin: 0 auto;
padding: 10px;
height: 350px;
width: 500px;
}
HTML:
<div id="vertical-center"></div>
<div id="content">
<h1>Centered Content</h1>
<p>This content is centered on the page.</p>
<p>More importantly, it won't get cut off when the browser window becomes too small to display it.</p>
</div>
Note that the #vertical-center has a margin-top that has to be half the height of the #content div, and it has to be negative.
