I have a little problem with some of the images on my website. I have a 280x310 div-container, but all of my images are bigger than this container. I'd like to maintain the aspect ratio of the images, and fit them to the full height of the div, cropping any extra parts of the image on the left and right (keeping the image centered). Is this possible in css? Thanks for your help.
Add this to your css code
.imgfit { width: 250px; height:500px; object-fit: cover}
Object-fit will do the job for you.
Place the image as a background image for the div and use background-size: contain (to see all of the image) or background-size: cover (to scale and crop)
Check out Set size on background image with CSS?
This can be achieved with a little bit of jQuery:
By setting overflow:hidden to the div containing the image, and height:100% to the image, it will be resized to fill the height of the div, without distortion. Then we use jQuery to center the image with position:absolute.

HTML:
<div class="container">
<img src="http://placehold.it/350x150">
</div>
<div class="container2">
<img src="http://placehold.it/350x150" class="imageid">
</div>
<div class="container2">
<img src="http://placehold.it/600x300" class="imageid">
</div>
CSS:
.container {
border:1px solid red;
width: 280px;
height:310px;
}
.container2 {
border:1px solid blue;
width: 280px;
height:310px;
overflow: hidden;
position:relative;
}
.container2 img {
height:100%;
}
.js-fix {
position:absolute;
top:0;
left:50%;
}
jQuery:
$(".imageid").each(function(){
var hWide = ($(this).width())/2; //half the image's width
hWide = '-' + hWide + 'px';
$(this).addClass("js-fix").css({
"margin-left" : hWide,
});
});
(jQuery code borrowed from here)
position: fixed;
x-overflow: hidden;
max-width: 100%
You can do this using html:
<img src='image.jpg' alt='Image' width='240' height='310'/>
You can view more of this at http://www.w3schools.com/tags/att_img_height.asp
Also, using css you can make a class or ID for the image itself:
img.sized{
height:310px;
width:210px;
}
Then use the class in your img tag:
<img src='image.jpg' class='sized'/>
You can read more about CSS sizing on http://www.w3schools.com/css/css_dimension.asp

Here's the fiddle I'd like to have those divs in right column to fill the height. So the first div should start at the top, and the last should end at the bottom, and the space between each div would be the same. How can I achieve this ?
<div>
<div class="left">
<img src="http://serwer1307713.home.pl/bg.png" />
</div>
<div class="right">
<img src="http://serwer1307713.home.pl/bg-2.png" />
<img src="http://serwer1307713.home.pl/bg-2.png" />
<img src="http://serwer1307713.home.pl/bg-2.png" />
<img src="http://serwer1307713.home.pl/bg-2.png" />
</div>
This is how I would like to make it looks like
I've forgotten to add one important info, I need that to be responsive ;)
I think this is what you mean, your images do not reach the end of the page?
Add this to your CSS file:
body {
padding:0;
margin:0;
}
It's not that easy, but I think I did it: http://jsfiddle.net/Whre/X3vKd/2/
I added some wrapping divs and used :before and :after pseudo elements to enforce equal heights:
.wrapper {
position:relative;
display:inline-block;
}
.wrapper:after {
content:".";
display:block;
visibility:hidden;
height:0;
}
Assign a height property to your html and your respective divs, then you can manually specify the height for the images in your right or left divs, like so:
.left img {
height: 42%;
}
.right img {
height: 10%;
}
html, body {
height: 100%;
}

I have done this with js. Have a look

I am building a website and I am using 2000px wide images. I want the images to be visible on wide screens (like mine - im using TV as monitor) but the smaller screens will only see the images size adequate to their size. (rest will be cropped). The problem is that the image must be centered no matter what size the viewport is. I have used text-align:center; to make the text responsive. I did read the similar topics but no matter what I do the image stays static and not centered. Please help.
HTML:
<body>
<div id="wrapper">
<div class="header">
<img src="images/design/header.png">
</div>
<div class="nav-bar">
Home
About
Portfolio
Gallery

</div>
<div class="side-bar">
<h1>This is my side bar</h1>
</div>
<div class="content">
<h1>This is my content</h1>
</div>
<div class="footer">
<h1>This is my footer</h1>
</div>
</div>
</body>
CSS:
#wrapper {
max-width: 2000px;
margin: -8px;
overflow: hidden;
text-align: center;
}
One way is to use a responsive layout. Twitter Bootstrap provides the same by default.
Another way is by using #media tags. Refer http://www.w3schools.com/css/css_mediatypes.asp . Here, you will need to make a function like this: Get the screen size using mediacheck and then set up thresholds using #media.
Use the following css to make the image center. max-width:100% will fit the image if the container is smaller than the image width. the image width and height will be reduced to fit.
#wrapper > .header img
{
display: block;
height: auto;
max-width: 100%;
margin:0 auto; /* to make the image center of its container, if container is larger than image size */
}
Update
If you know the exact height of the image, then please see this fiddle. Resize fullscreen to see the image cropping.
HTML:
<div class="position-img-outer">
<div class="position-img-inner">
<img src="http://placehold.it/1000x300" class="position-img" alt="img" style=" height: 300px; " />
</div>
</div>
CSS:
.position-img-outer
{
height: 300px;
margin: 0 auto;
overflow: hidden;
}
.position-img-outer .position-img-inner
{
display: inline-block;
position: relative;
right: -50%;
}
.position-img-outer .position-img-inner .position-img
{
position: relative;
left: -50%;
}
If you know the width of the images, you can use the following:
#wrapper .header img{
position:relative;
width:2000px;
left:50%;
margin-left:-1000px;
}
UPDATE:
To avoid a horizontal Scrollbar, you can set the container element to width:100% and overflow:hidden
#wrapper .header {
position:relative;
width:100%;
overflow:hidden;
}
First, please consider this fiddle.
I need to get some links over specific image regions, however those images are scaled according to the parent size...
that's why the link's position and size are relative(percentages) to the image.
But the fiddle shows the problem of this approach.
Is there anyway to get the .image-wrapper to "mimic" the img size and position after scaled?! Any trick or whatever?
Note: I'm OK with webkit-only solutions!
Edit 1
Actually I'm more focused in making the image fit on the content div, then making the image wrapper follow the resulting image size. Here's what I achieved so far...
Now I'm trying to get it working with the image centralized.
Here is the CSS skeleton for a solution.
Suppose your HTML looks like the following:
<div id="content1" class="content portrait">
<div class="panel-wrapper">
<div class="image-wrapper">
<img src="http://placekitten.com/200/250" />
</div>
</div>
</div>
<div id="content2" class="content landscape">
<div class="panel-wrapper">
<div class="image-wrapper">
<img src="http://placekitten.com/300/200" />
</div>
</div>
</div>
The HTML is similar to your original code except that there is an extra wrapper .panel-wrapper.
I used the following CSS:
.content {
background: lightgray;
display: table;
margin: 40px 0;
}
#content1 {
width:100px;
height:150px;
}
#content2 {
width:150px;
height:150px;
}
.panel-wrapper {
display: table-cell;
vertical-align: middle;
text-align: center;
}
.image-wrapper {
outline: 1px solid green;
position:relative;
display: inline-block;
}
.content img {
display: block;
width: 100%;
}
.portrait .image-wrapper {
height: calc(100% - 2px);
}
.portrait .img {
height: 100%;
}
.landscape .image-wrapper {
width: calc(100% - 2px);
}
.landscape .img {
width: 100%;
}
.sample-link {
background:rgba(0, 0, 255, 0.3);
position:absolute;
display:block;
width: 50%;
height:20%;
top:5%;
left:5%;
}
I apply display: table to .content and display: table-cell to .panel-wrapper so that I can get a get the image centered both vertically and horizontally.
The .image-wrapper has display: inline-block.
To get the scaling right, you need to consider two cases depending on the aspect ratio of the image.
For portrait images, apply height: 100% to the .image-wrapper and the child img.
For landscape images, apply width: 100% respectively.
If you have a border on .image-wrapper, use the CSS calc() function to adjust for the 2px width of the borders.
What you need to do is use JavaScript/jQuery to determine the aspect ratio of the image and then apply the correct class (.portrait or .landscape) to the .content block.
See demo at: http://jsfiddle.net/audetwebdesign/SZjvJ/
A possible way is to work with image ratio and to adjust link ratio and margins according to image dimensions, with Jquery.
Have a look at this example fiddle: http://jsfiddle.net/t7Ucj/
The Js measures width and height of the image and according to its ratio, it works on the width or on the height of the link.
var width = $('#content2 img').width();
var height = $('#content2 img').height();
//vertical image
if(height > width){
var left = $('#content2 img').css('margin-left');
$('#content2 .sample-link').css({'width': width, 'left' : left});
}
else{
var top = $('#content2 img').css('margin-top');
$('#content2 .sample-link').css({'height': height*0.2, 'top' : top + height*0.4});
}
Then you can wrap all the instructions in a simple function obviously.
I know it can be tricky to put all the possible cases but i had a similar problem and solved in this way.
hope it helps
I'm trying to achieve, that the div's will behave like an example on picture, using css:
Is there any clean way to do this? I achieve this using javascript to calculate "left" div height and "main" div width and height. But i dont like this solution...is there any way to do this using css only?
Edit:
Page must not have scrollbar...so page's height is always max 100%, and no more...
thanks
If the sidebar (or any other div) is 100% height, and on top you have a 30px header, so that causes your container to be 100% + 30px height.
In the future you will have in css3 calc():
http://hacks.mozilla.org/2010/06/css3-calc/
This will solve your problem.
But for now you can add overflow: hidden; to the html and body section, but I recommend calculate the height of the sidebar ( container height - header height) using Javascript.
Check fiddle here
If you mean the two-column layout, you do it with pure CSS like this:
.container {
background-color: #aaaaaa;
}
.left {
float: left;
width: 100px;
clear: left;
}
.right {
margin-left: 100px;
background-color: #888888;
}
and HTML:
<div class="container">
<div class="left">left</div>
<div class="right">right</div>
</div>
Live demo: jsFiddle
The div on top can be achieved without any special CSS. To place something below (a footer for example), you'll need to use clear: both.
Without any code it is hard to determine what you want. Here is a extremely simple version of what I believe you want.
HTML:
<div id="header">
</div>
<div id="side">
</div>
<div id="content">
</div>
CSS:
#header {
width:100%;
height:50px;
}
#side {
width:300px;
height:100%;
float:left;
}
#content {
width:660px;
height:100%;
float:left;
}

So yet another question about vertically aligning an image within a div, but I think mine is different than the others I've found on here. I can't seem to find a solution that works for my situation.
I have a DIV that is 100% width (to it's container, which is floating left and has a set pixel width) and has a set pixel height. I have an image inside that I am positioning absolute to get it to the background of content within the DIV. The image is fluid with a width of 100%.
All works well, but I want to get the image to vertically align to the middle of the container and height is unknown.
Here is some sample code that shows what I'm trying to do:
<div class="container">
<div class="image-wrapper">
<img src="http://farm5.staticflickr.com/4111/4968056789_d872094672_o.jpg"
width="100%" />
</div>
<p>Some text</p>
</div>
And some sample CSS:
.container {
width:100%;
margin-top:10px;
height:100px;
overflow:hidden;
}
.image-wrapper {
position: relative;
}
.image-wrapper > img {
position: absolute;
z-index: -1;
}
p {
text-align: center;
padding-top: 10px;
color:#fff;
font-weight: bold;
}
But the flower should show up with it's center visible within the container div.
Any thoughts? I'm trying to avoid any Javascript sizing (the outer container, not shown in this sample, is already being sized). I'm not opposed to more DIVs, tables.. whatever you got!
A jsFiddle to demo this:
http://jsfiddle.net/JonMcL/sNz9h/
Why not go for the background-image property? That allows vertical centering...

Assuming you want to only scale the image down and not stretch it beyond its native resolution this should do the trick. A little bit of jQuery is involved but it's minimal. Essentially, this adjusts the top-margin of the IMG on the window.resize event.
HTML
<div id="container">
<img id="image" src="image.jpg"> <!-- native size is 480x300 -->
</div>
CSS
#container {
margin: auto;
width: 80%;
height: 300px;
border: 1px solid gray;
}
#image {
display: block;
width: 100%;
max-width: 480px;
margin: auto;
}
jQuery
function adjustImage() {
$("#image").css('margin-top', ($("#container").height() - $("#image").height()) / 2);
}
$(window).load(function() {
adjustImage();
$(window).resize(function() {
adjustImage();
});
});
If I get what you need I would suggest setting the background image via css, then you can set the position correctly etc.
.container {
width:100%;
margin-top:10px;
background-image:url("http://farm5.staticflickr.com/4111/4968056789_d872094672_o.jpg");
background-repeat:no-repeat;
background-position:left center;
height:100px;
overflow:hidden;
}
