I need mix-blend-mode element in my project, so I use mix-blend-mode property.
It looked fine at first, but as the screen narrowed, it changed to an unexpected appearance.
Also overflow: hidden doesn't work, so blue comes out of the corner.
I run this code in Chrome browser.
Looks different depending on screen width
.card{
position: relative;
width: 300px;
height: 50vh;
background-color: pink;
margin: auto;
overflow: hidden;
border-radius: 24px;
}
.blend{
width: 100%;
height: 100%;
background-color: blue;
mix-blend-mode: color-dodge;
will-change: transform;
}
<div class="card">
<div class="blend"></div>
</div>
Here's my code.
Please let me know why this problem happen.
Thank you!
I think border-radius, overflow, mix-blend-mode and will-change properties seems to be contributing to this problem, but still I don't know ★why★ this happens.
while using border-radius Opera won't actually hide the overflowing parts of elements. I already tried to apply things I managed to find in similar threads, such as defining the border style or paying attention to positioning with absolute and relative parameters. It is still not working though.

Thanks for any help.
Actually the code you provided works in latest Opera with Blink engine, so I guess you can leave your code as is. However if you need it to work in versions up to 12.16 and your page background is white, what you can do is to put .png overlay over your chart which will clip the chart, just like webdevelopers did in old days when there were no border-radius:)
According to the W3 specification:
http://www.w3.org/TR/css3-background/#corner-clipping
A box's backgrounds, but not its border-image, are clipped to the
appropriate curve (as determined by ‘background-clip’). Other effects
that clip to the border or padding edge (such as ‘overflow’ other than
‘visible’) also must clip to the curve. The content of replaced
elements is always trimmed to the content edge curve.
It appears that Firefox implemented the spec correctly by clipping the content to the edge of the curve when using overflow: hidden.
However, Opera is not compliant on this detail.
As an aside, if you add border-radius property to an img element, the image will be clipped correctly.
At this moment, there is no work-around that I know of unless you try HTML5 canvas.
What is the proper way to create responsive, transparent CSS captions over images — with graceful degradation in older browsers?
I am trying to achieve:
Centered vertical column of images
Images are equal heights and widths
Each image has a caption which should be centered
Caption should have a see-through background
Would be nice if the background became black in older browsers that don't support transparency
If you take a look at this Fiddle example, there's clearly a lot wrong with it.
The basic premise for HTML5 is:
<section>
<figure>
<img src="1.jpg">
<figcaption>Caption 1</figcaption>
</figure>
<figure>
<img src="2.jpg">
<figcaption>Caption 2</figcaption>
</figure>
<figure>
<img src="3.jpg">
<figcaption>Caption 3</figcaption>
</figure>
</section>
But the CSS3 code is where we get some problems. Is it the right approach even? I got it to work with some fine-tuning (not included), but the fine-tuning doesn't seem to make semantic sense to me anyway.
For example, this is the result:
I have a feeling the CSS is wrong on many levels (pun intended).
I modified your CSS slightly. The main changes were adding position: relative; to the parent element and position: absolute; to the caption.
CSS:
section {
overflow: auto;
}
section figure {
float: left;
clear: both;
position: relative;
overflow: auto;
margin: 0 auto;
padding: 30px 0 0 0;
font-size: 15px;
}
section figure img {
vertical-align: bottom;
}
section figure figcaption {
position: absolute;
bottom: 0;
left: 0;
right: 0;
background: rgba(0,0,0,0.7);
text-align: center;
color: #fff;
padding: 10px;
}
section {
padding-bottom: 30px;
background: #ccc;
}

At the moment I have this, a small DIV that slides in from the top to the center of a container DIV when the mouse hovers over the container DIV; but on mouseout, it slides back out to where it came from. What I'd like to do is have the DIV slide out of the other side of the DIV, directly opposite where it entered.
Is this possible using just CSS? (I imagine with JQuery it would be more straightforward)
<div class="blocks">
<div class="blocks_title">
</div>
</div>
<div class="blocks">
<div class="blocks_title">
</div>
</div>
.blocks {
position: relative;
float: left;
margin: 20px;
width: 100px;
height: 100px;
border: 1px dotted #333;
overflow: hidden;
}
.blocks_title {
position: relative;
width: 20px;
height: 20px;
top: 0px;
left: 40px;
background: #333;
opacity: 0;
-webkit-transition: all .25s;
-moz-transition: all .25s;
transition: all .25s;
}
.blocks:hover .blocks_title {
top: 40px;
opacity: 1;
}
And just when everyone is convinced that it's not gonna work with css only:
http://jsfiddle.net/Xkee9/36/
I used an animation for the mouseenter and a transiton for the mouseleave
Edit: added firefox fix
Edit: Explanation:
(I always use -webkit- -prefixes, just to explain it in Chrome and Safari, Firefox uses the -moz- -prefix, opera the -o- - prefix)
When nothing happens:
the block is at the bottom of the div.blocks (top:80px;), with an opacity of 0, also there is no animation running
When hovering:
the block moves instantaneous to the top with no transition (see:-webkit-transition: none;), because then the animation down-1 is running. That animation moves the block from top:0 to top:40px; in .25s. After the animation, the block stays at top:40px; because that's what I added in .blocks:hover .blocks_title.
When mousleaving:
there is no animation running anymore, but the block moves from top:40px to top:80px; in .25s because of -webkit-transition: all .25s;
I need to make this image stretch to the maximum size possible without overflowing it's <div> or skewing the image.
I can't predict the aspect-ratio of the image, so there's no way to know whether to use:
<img src="url" style="width: 100%;">
or
<img src="url" style="height: 100%;">
I can't use both (i.e. style="width: 100%; height: 100%;") because that will stretch the image to fit the <div>.
The <div> has a size set by percentage of the screen, which is also unpredictable.
Update 2016:
Modern browser behave much better. All you should need to do is to set the image width to 100% (demo)
.container img {
width: 100%;
}
Since you don't know the aspect ratio, you'll have to use some scripting. Here is how I would do it with jQuery (demo):
CSS
.container {
width: 40%;
height: 40%;
background: #444;
margin: 0 auto;
}
.container img.wide {
max-width: 100%;
max-height: 100%;
height: auto;
}
.container img.tall {
max-height: 100%;
max-width: 100%;
width: auto;
}
HTML
<div class="container">
<img src="http://i48.tinypic.com/wrltuc.jpg" />
</div>
<br />
<br />
<div class="container">
<img src="http://i47.tinypic.com/i1bek8.jpg" />
</div>
Script
$(window).load(function(){
$('.container').find('img').each(function(){
var imgClass = (this.width/this.height > 1) ? 'wide' : 'tall';
$(this).addClass(imgClass);
})
})
There is a much easier way to do this using only CSS and HTML:
HTML:
<div
class="fill"
style="background-image: url('path/to/image.jpg');">
</div>
CSS:
.fill {
background-size: cover;
background-position: center;
width: 100%;
height: 100%;
}
This will place your image as the background, and stretch it to fit the div size without distortion.
Not a perfect solution, but this CSS might help. The zoom is what makes this code work, and the factor should theoretically be infinite to work ideally for small images - but 2, 4, or 8 works fine in most cases.
#myImage {
zoom: 2; //increase if you have very small images
display: block;
margin: auto;
height: auto;
max-height: 100%;
width: auto;
max-width: 100%;
}
If you're able to set the image as a background-image then you can do something like this, which will crop the image without stretching it:
<div style="background-image: url(...); background-size: cover; width: 100%; height: 100%;"></div>
If you need to stick with an <img> tag, then as of 2019, you can now use the object-fit css property that accepts the following values:
fill | contain | cover | none | scale-down
See https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit
As an example, you could have a container that holds an image:
<div class="container">
<img src="" class="container_img" />
</div>
.container {
height: 50px;
width: 50%;
}
.container_img {
height: 100%;
width: 100%;
object-fit: cover;
}
If you can, use background images and set background-size: cover. This will make the background cover the whole element.
CSS
div {
background-image: url(path/to/your/image.png);
background-repeat: no-repeat;
background-position: 50% 50%;
background-size: cover;
}
If you're stuck with using inline images there are a few options. First, there is
object-fit
This property acts on images, videos and other objects similar to background-size: cover.
CSS
img {
object-fit: cover;
}
Sadly, browser support is not that great with IE up to version 11 not supporting it at all. The next option uses jQuery
CSS + jQuery
HTML
<div>
<img src="image.png" class="cover-image">
</div>
CSS
div {
height: 8em;
width: 15em;
}
Custom jQuery plugin
(function ($) {
$.fn.coverImage = function(contain) {
this.each(function() {
var $this = $(this),
src = $this.get(0).src,
$wrapper = $this.parent();
if (contain) {
$wrapper.css({
'background': 'url(' + src + ') 50% 50%/contain no-repeat'
});
} else {
$wrapper.css({
'background': 'url(' + src + ') 50% 50%/cover no-repeat'
});
}
$this.remove();
});
return this;
};
})(jQuery);
Use the plugin like this
jQuery('.cover-image').coverImage();
It will take an image, set it as a background image on the image's wrapper element and remove the img tag from the document. Lastly you could use
Pure CSS
You might use this as a fallback. The image will scale up to cover it's container but it won't scale down.
CSS
div {
height: 8em;
width: 15em;
overflow: hidden;
}
div img {
min-height: 100%;
min-width: 100%;
width: auto;
height: auto;
max-width: none;
max-height: none;
display: block;
position: relative;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
Hope this might help somebody, happy coding!
Thanks to CSS3
img
{
object-fit: contain;
}
https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit
IE and EDGE as always outsiders:
http://caniuse.com/#feat=object-fit
That's impossible with just HTML and CSS, or at least wildly exotic and complicated. If you're willing to throw some javascript in, here's a solution using jQuery:
$(function() {
$(window).resize(function() {
var $i = $('img#image_to_resize');
var $c = $img.parent();
var i_ar = $i.width() / $i.height(), c_ar = $c.width() / $c.height();
$i.width(i_ar > c_ar ? $c.width() : $c.height() * (i_ar));
});
$(window).resize();
});
That will resize the image so that it will always fit inside the parent element, regardless of it's size. And as it's binded to the $(window).resize() event, when user resizes the window, the image will adjust.
This does not try to center the image in the container, that would be possible but I guess that's not what you're after.
You can use object-fit: cover; on the parent div.
https://css-tricks.com/almanac/properties/o/object-fit/
Set width and height of the outer container div. Then use below styling on img:
.container img{
width:100%;
height:auto;
max-height:100%;
}
This will help you to keep an aspect ratio of your img
If you want to set a max width or height (so that it will not be very large) while keeping the images aspect-ratio, you can do this:
img{
object-fit: contain;
max-height: 70px;
}
I came across this question searching for a simular problem. I'm making a webpage with responsive design and the width of elements placed on the page is set to a percent of the screen width. The height is set with a vw value.
Since I'm adding posts with PHP and a database backend, pure CSS was out of the question. I did however find the jQuery/javascript solution a bit troblesome, so I came up with a neat (so I think myself at least) solution.
HTML (or php)
div.imgfill {
float: left;
position: relative;
background-repeat: no-repeat;
background-position: 50% 50%;
background-size: cover;
width: 33.333%;
height: 18vw;
border: 1px solid black; /*frame of the image*/
margin: -1px;
}
<div class="imgfill" style="background-image:url(source/image.jpg);">
This might be some info
</div>
<div class="imgfill" style="background-image:url(source/image2.jpg);">
This might be some info
</div>
<div class="imgfill" style="background-image:url(source/image3.jpg);">
This might be some info
</div>
By using style="" it's posible to have PHP update my page dynamically and the CSS-styling together with style="" will end up in a perfectly covered image, scaled to cover the dynamic div-tag.
To make this image stretch to the maximum size possible without overflowing it's or skewing the image.
Apply...
img {
object-fit: cover;
height: -webkit-fill-available;
}
styles to the image.
Using this method you can fill in your div with the image varying ratio of divs and images.
jQuery:
$(window).load(function(){
$('body').find(.fillme).each(function(){
var fillmeval = $(this).width()/$(this).height();
var imgval = $this.children('img').width()/$this.children('img').height();
var imgClass;
if(imgval > fillmeval){
imgClass = "stretchy";
}else{
imgClass = "stretchx";
}
$(this).children('img').addClass(imgClass);
});
});
HTML:
<div class="fillme">
<img src="../images/myimg.jpg" />
</div>
CSS:
.fillme{
overflow:hidden;
}
.fillme img.stretchx{
height:auto;
width:100%;
}
.fillme img.stretchy{
height:100%;
width:auto;
}
This did the trick for me
div img {
width: 100%;
min-height: 500px;
width: 100vw;
height: 100vh;
object-fit: cover;
}
if you working with IMG tag, it's easy.
I made this:
<style>
#pic{
height: 400px;
width: 400px;
}
#pic img{
height: 225px;
position: relative;
margin: 0 auto;
}
</style>
<div id="pic"><img src="images/menu.png"></div>
$(document).ready(function(){
$('#pic img').attr({ 'style':'height:25%; display:none; left:100px; top:100px;' })
)}
but i didn't find how to make it work with #pic { background:url(img/menu.png)}
Enyone?
Thanks
I had similar issue. I resolved it with just CSS.
Basically Object-fit: cover helps you achieve the task of maintaining the aspect ratio while positioning an image inside a div.
But the problem was Object-fit: cover was not working in IE and it was taking 100% width and 100% height and aspect ratio was distorted. In other words image zooming effect wasn't there which I was seeing in chrome.
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.
Here is a demonstration of the above logic.
https://jsfiddle.net/furqan_694/s3xLe1gp/
This logic works in all browsers.
HTML:
<style>
#foo, #bar{
width: 50px; /* use any width or height */
height: 50px;
background-position: center center;
background-repeat: no-repeat;
background-size: cover;
}
</style>
<div id="foo" style="background-image: url('path/to/image1.png');">
<div id="bar" style="background-image: url('path/to/image2.png');">
JSFiddle
...And if you want to set or change the image (using #foo as an example):
jQuery:
$("#foo").css("background-image", "url('path/to/image.png')");
JavaScript:
document.getElementById("foo").style.backgroundImage = "url('path/to/image.png')";
Many of the solutions found here have some limitation: some not working in IE ( object-fit) or older browsers, other solutions do not scale up the images (only shrink it), many solution do not support resize of the window and many are not generic, either expect fix resolution or layout(portrait or landscape)
If using javascript and jquery is not a problem I have this solution based on the code of #Tatu Ulmanen. I fixed some issues, and added some code in case the image is loaded dinamically and not available at begining. Basically the idea is to have two different css rules and apply them when required: one when the limitation is the height, so we need to show black bars at the sides, and othe css rule when the limitation is the width, so we need to show black bars at the top/bottom.
function applyResizeCSS(){
var $i = $('img#imageToResize');
var $c = $i.parent();
var i_ar = Oriwidth / Oriheight, c_ar = $c.width() / $c.height();
if(i_ar > c_ar){
$i.css( "width","100%");
$i.css( "height","auto");
}else{
$i.css( "height","100%");
$i.css( "width","auto");
}
}
var Oriwidth,Oriheight;
$(function() {
$(window).resize(function() {
applyResizeCSS();
});
$("#slide").load(function(){
Oriwidth = this.width,
Oriheight = this.height;
applyResizeCSS();
});
$(window).resize();
});
For an HTML element like:
<img src="images/loading.gif" name="imageToResize" id="imageToResize"/>
try this
HTML:
<div class="container"></div>
CSS:
.container{
background-image: url("...");
background-size: 100%;
background-position: center;
}
