Background
I need to have an image larger than its container. The idea is to give the users the option to add full-width images to content pages, if they want to.
Problem
I used calc(100vw) with left: 50%; and translateX(-50%). This works perfectly in Chrome and Firefox. However, IE11 and Edge bring a horizontal scroll bar.
Code
HTML
<div>
<img />
</div>
CSS
div {
margin: 0 auto;
width: 400px;
}
img {
display: block;
left: 50%;
position: relative;
transform: translateX(-50%);
width: calc(100vw);
}
Fiddle
Here's an example so you can test and play: https://jsfiddle.net/Cthulhu/nbmy5mjf/1/
Question
How can I remove/hide the scroll bar from IE and Edge?
I thought this happened due to the way the image's position is being calculated. However, I noticed that Firefox and Chrome also show a scroll bar if I remove the display: block; from the image. Any ideas?
use
body {
overflow: hidden
}
or just:
body {
overflow-x: hidden
}
and drop the calc() it isn't doing anything there.
Snippet
body {
overflow: hidden
}
div {
border: 5px solid red;
margin: 0 auto;
width: 400px;
}
img {
display: block;
left: 50%;
position: relative;
transform: translateX(-50%);
width: 100vw;
overflow: hidden
}

OK, this is a bit of a mouthful and very super specific. I will try my best to explain!
The goal is to maintain aspect ratio while scaling an image and keeping it vertically and horizontally centred inside a DIV that is defined only by percentages. The image needs to maintain best fit, so if max width is required then it's used and vice versa.
Use Firefox version 33 (or a few earlier versions) to view this js fiddle to see it working properly:
http://jsfiddle.net/3vr9v2fL/1/
HTML:
<div id="imageviewer" >
<div class="dummy"></div>
<div class="img-container centerer" id="imagevieweroriginal">
<img class="centered" src="http://chrisnuzzaco.com/couch/uploads/image/gallery/smiling_woman_wearing_drivers_cap.jpg" alt="Doctor Concentrating on Work"></img>
</div>
</div>
</div>
CSS:
#imagewrapper{
position:absolute;
width:69%;
height:100%;
top:0px;
bottom:0px;
background-color:gray;
}
#imageviewer{
position:relative;
width:100%;
height:100%;
}
.responsive-container {
position: relative;
width: 100%;
border: 1px solid black;
}
.dummy {
padding-top: 100%; /* forces 1:1 aspect ratio */
}
.img-container {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
}
.centerer {
text-align:center; /* Align center inline elements */
font: 0/0 a; /* Hide the characters like spaces */
}
.centerer:before {
content: ' ';
display: inline-block;
vertical-align: middle;
height: 100%;
}
.centered {
vertical-align: middle;
display: inline-block;
max-height: 100%;
max-width: 100%;
}
The Problem:
I originally found my code here on stackoverflow and made a simple mod adding max-height/width to the .centered class. At the time, this worked in all major browsers. The only exception being Opera.
Vertically align an image inside a div with responsive height
There is a big problem however: the latest version of Chrome (Version 38.0.2125.111) no longer works with this code and my users prefer chrome to other browsers by a large margin.
Any ideas on how to solve this? Is this a bug with Chrome? I'm open to javascript suggestions to make this work again.
I came up with this: JSFiddle - centered image keeps aspect ratio in resizable fluid container
.container {
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
width: 100%;
height: 100%;
}
.image {
position: absolute;
max-width: 100%;
max-height: 100%;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
body {
width: 100%;
height: 100%;
position: absolute;
margin: 0;
}
<div class='container'>
<img class='image' src='http://imgsv.imaging.nikon.com/lineup/lens/zoom/normalzoom/af-s_dx_18-140mmf_35-56g_ed_vr/img/sample/sample1_l.jpg'>
</div>
The image stays centered both horizontally and vertically. If the window is scaled down the image shrinks respecting original aspect ratio.
I didn't test it on all browsers though.
Take a look at CSS object-fit property:
You may need a polyfill for older browsers, though.
View browser support for object-fit.
i want to place text on top of the image inside container with width 80%
conainer.width 80% - code below not working
conainer.width 100% - code below working
screen shot of my brouser
<style type="text/css">
.conainer {
margin: auto;
width: 80%; /* change that to 100% code will work */
border: thin solid #000;
}
h2 {
position: absolute;
top: 200px;
left: 0;
width: 100%;
}
.image {
position: relative;
width: 100%; /* for IE 6 */
}
</style>
<div class="conainer">
<div class="image">
<img src="img/banners.jpg" width="100%" height="100%" />
<h2>some text gos here</h2>
</div>
</div>
You should just set the background of your div, instead of trying to place the h2 on top of an img tag
It works for me. Is there any more code?
I think the most code-efficient and compatible method would be to define your banner image as the background-image of div.image using CSS.
Replace your h2 style as
h2 {
position: fixed;//yours is on top of image but absolutely positioned, so not visible
top: 200px;
left: 0; //Specify where you want to put your image with top and left properly now.
width: 100%;
}
Ok! i found the problem change top 200 => top 0
h2 {
position: absolute;
top: 0px;
left: 0;
width: 100%;
UPDATE 2: Making further progress. Almost there!
jsFiddle: http://jsfiddle.net/persianturtle/Tfemm/6/
The sprite is now 99% responsive, except that the
margin-bottom: %
Does not line up perfectly as the page changes width. The
margin-left: %
Seems to work great.
Any thoughts on how to align the margin-bottom perfectly?
UPDATE: Making progress, but still not yet there.
Below is the jsFiddle: http://jsfiddle.net/persianturtle/Tfemm/5/
The sprite image that I wanted to crop is working responsively, except it is only being cropped horizontally and not vertically.
The Code below:
<div class="responsive-sprite" style="width: 100%;">
<img alt="Yay for alt tags..." src="http://zx85.dyndns.org/raphtest/img/nav-buttons2.jpg" />
</div>
img {
width: 100%;
height: 200%;
margin-left: -81.869%;
}
.responsive-sprite {
overflow: hidden;
}
Can anyone think of a way to crop this vertically as well?
Below is the original post:
Is there a way to make CSS sprites responsive?
Take a look at the attached jsFiddle: http://jsfiddle.net/persianturtle/Tfemm/2/
Is there a way to resize this CSS sprite once the container can no longer fit the full size image?
<div class="container">
<h2 class="popular"><img src="http://zx85.dyndns.org/raphtest/img/nav-buttons2.jpg" alt="" />Featured</h2>
</div>
.container {
width: 20%;
margin: 0 auto;
}
h2 {
overflow: hidden;
position: relative;
height: 128px;
width: 192px;
max-width: 100%;
}
h2 img {
position: relative;
}
h2.popular img {
top: 0;
left: -867px;
}
h2.popular img:hover {
top: -128px;
left: -867px;
}
Hmmm. Tricky.
I haven't tested but would it work to orient the sprite horizontally instead of vertically and then:
h2 {
overflow: hidden;
position: relative;
width: 192px;
max-width: 100%;
}
h2 img {
position: relative;
width: 200%;
}
h2.popular img {
top: 0;
left: 0;
}
h2.popular:hover img {
top: 0;
left: -100%;
}
Edit:
Seems to work, the sprite just needs to be configured. Have a look at this JSFiddle.
Unfortunately, I think you will have to do each button individually because the image height is what determines the button height when it is resized.
I am working on a website and the client wants to have something similar to this: http://www.csszengarden.com/?cssfile=202/202.css
There are several overlays that are attached to the edges of the screen, while the text in the center is contained in such a way that the original browser scroll bars remain usable. This design is made elastic by allowing it to stretch at least vertically through an extra div.
The tricky part about my design: I have a fixed size div that is supposed to be centered both vertically and horizontally. What I need now are further divs that surround the centered div and expand as the user resizes their window, in order to serve as overlays to hide the text below them.
This is basically it: http://imgur.com/TNaTU
So broken down even further, what I need is a way to have the four surrounding divs automatically expand or reduce their size so they always fill up all of the screen.
Is there a way to do this without Javascript?
This won't work in IE7 without some crazy hacks, because IE7 does not support display: table and friends.
I will have a look at making this work in IE7 if it's a requirement for you.
Tested in IE8 and recent versions of Firefox, Chrome, Safari, Opera.

Normally, you center images with display: block; margin: auto, but if the image is larger than the container, it overflows to the right. How do I make it overflow to the both sides equally? The width of the container is fixed and known. The width of the image is unknown.
A pure css solution
Requiring one extra wrapper (tested in FireFox, IE8, IE7):
Improved Answer
There was a problem with the original answer (below). If the image is larger than the container that outer is centered on with it's auto margins, then it truncates the image on the left and creates excessive space on the right, as this fiddle shows.
We can resolve that by floating inner right and then centering from the right. This still truncates the img off the page to the left, but it does so by explicitly pushing it that way and then centers back off of that, the combination of which is what prevents the extra horizontal scroll on the right. Now we only get as much right scroll as we need in order to see the right part of the image.
Fiddle Example (Borders in fiddle are for demo only.)
Essential CSS
div.outer {
width: 300px; /* some width amount needed */
margin: 0 auto;
overflow: visible;
}
div.inner {
position:relative;
float: right; /* this was added and display removed */
right: 50%;
}
div.inner img {
position: relative;
right:-50%; /* this was changed from "left" in original */
}
If you desire no right scroll at all for wide images
Then using the above, also set whatever element wraps outer (like body or a third wrapper) to have overflow: hidden.
Original Idea (for History)
Fiddle Example (Borders in fiddle are for demo only.)
HTML
<div class="outer">
<div class="inner">
<img src="/yourimage.png">
</div>
</div>
CSS
div.outer {
width: 300px; /* some width amount needed */
margin: 0 auto;
overflow: visible;
}
div.inner {
display: inline-block;
position:relative;
right: -50%;
}
div.inner img {
position: relative;
left:-50%;
}
Here's a 2 line CSS solution (a couple more lines might be required for cross-browser support):
img {
margin-left: 50%;
transform: translateX(-50%);
}
HTML
<div class="image-container">
<img src="http://www.google.com/images/logo.gif" height="100" />
</div>
CSS
.image-container {
width: 150px;
border: solid 1px red;
margin:100px;
}
.image-container img {
border: solid 1px green;
}
jQuery
$(".image-container>img").each(function(i, img) {
$(img).css({
position: "relative",
left: ($(img).parent().width() - $(img).width()) / 2
});
});
See it on jsFiddle: http://jsfiddle.net/4eYX9/30/
Alternative pure CSS solution is to use transform attribute:
HTML:
<div class="outer">
<img class="image" src="http://www.gstatic.com/webp/gallery/4.jpg" />
</div>
CSS:
.outer {
position: relative;
width: 100px;
border: 1px solid black;
height: 150px;
margin-left: 100px; /* for demo */
/* overflow: hidden; */
}
img.image {
width: 200px;
opacity: 0.7;
position: absolute;
left: 50%;
transform: translateX(-50%);
-webkit-transform: translateX(-50%);
}
Fiddle
Just to add a overflow:hidden to parent div to hide the extra area of the image.
Your best bet is to set it as background image of the container instead.
#container {
background: url('url/to/image.gif') no-repeat center top;
}
In fact there is a simpler pure css/html way (without large horizontal scroll) :
Html :
<div class="outer">
<img src="/my/sample/image.jpg">
</div>
Css :
If you don't want to see image overflow
div.outer img {
position: absolute;
left: -50%;
z-index:-1;
}
div.outer {
overflow: hidden;
position: relative;
height: 200px;
}
With image overflow visible
div.outer img {
position: absolute;
left: -50%;
z-index:-1;
}
div.outer {
overflow: visible;
position: relative;
height: 200px;
}
body, html {
overflow-x:hidden;
}
A background solution with image overflow visible :
Html :
<div class="outer">
<div class="inner"></div>
</div>
Css :
div.outer {
width: 100%;
height: 200px;
}
div.inner {
background: url('/assets/layout/bg.jpg') center no-repeat;
position: absolute;
left: 0;
width: 100%;
height: inherit;
}
assuming outer is in a width specified container.
I see this is an old post, so maybe everybody knows this by now, but I needed help for this and I solved it using flex:
.parent {
display: flex;
/* give it the width and height you like */
}
.parent img {
min-width: 100%;
min-height: 100%;
object-fit: cover;
}
I can only think of a Javascript solution since what you need to do is relatively position the image a negative amount to the left of its container:
jQuery
$(document).ready(function(){
var theImg = $('#container img');
var theContainer = $('#container');
if(theImg.width() > theContainer.width()){
theImg.css({
position: 'relative',
left: (theContainer.width() - theImg.width()) / 2
})
}
})
I found this to be a more elegant solution, without flex, similar to something above, but more generalized (applies on both vertical and horizontal):
.wrapper {
overflow: hidden;
}
.wrapper img {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
/* height: 100%; */ /* optional */
}
I don't think there is a pure CSS solution (Except for the next answer :)). However with Javascript it would be just a matter of finding the width of the image, subtracting the container width, dividing by two and you have how far to the left of the container you need.
