I have come across a problem while trying to make a background for my website. I am trying to have an image that can be scrolled and resized as seen on: https://sketchthemes.com/preview/?theme=98.
I have tried this:
<div id="back_img" style="background-image: url("test.jpg");"></div>
And then setting the style to:
#back_img {
width: 100%;
position: absolute;
top: 0;
left: 0;
}
But this does not contain all of the functionalities I wished for.
Setting background-attachment: fixed; and background-size: cover; will bring it closer to that effect, however to get the parallax scrolling you will need to write / use a script to adjust it's position based on the current scroll.
#back_img {
width: 100%;
position: absolute;
top: 0;
left: 0;
background-attachment: fixed;
background-size: cover;
}
Hi guys I was trying to swap the background of two images down the footer section of my website using skrollr.js (https://github.com/Prinzhorn/skrollr). For some reason it won't scroll at all. I am trying to create a parallax site that has fixed position on the part below.
See image: http://prntscr.com/6yrckx
Here's the Markup of that part:
<div id="starynight"
data-bottom-top="opacity: 1; background: !url(images/sunny.jpg); background-size: cover;"
data--40-top="opacity: 0.5; background: !url(images/night.jpg); background-size: cover;"
data--50-top="opacity: 0; background: !url(images/night.jpg); background-size: cover;"
data--60-top="opacity: 0.5; background: !url(images/night.jpg); background-size: cover;"
data--70-top="opacity: 1; background: !url(images/night.jpg); background-size: cover;"
>
</div>
While here's the CSS:
#starynight{
background: url('../images/sunny.jpg') no-repeat center;
width: 100%;
height: 307px;
background-size: cover;
}
#road{
background: url('../images/road.jpg') no-repeat center;
width: 100%;
height: 145px;
background-size:cover;
}
#car{
background: url('../images/car.png') no-repeat center;
width: 325px;
height: 125px;
display: block;
position: absolute;
z-index: 9999;
left: 950px;
top: 2100px;
}
My issue here is that when I scroll this part of my website it should swap the images of the sunny.jpg and night.jpg while the car is moving from right to left and also this background image must be fixed in position. For some reason my codes won't just work. Any idea what went wrong?
See my website here: http://goo.gl/aNOCiJ
Animating backgrounds is not like animating positions or "number" data. You can't just transform one background into another by fading them (actually Firefox somehow can animate the transition, but lets not depend on that).
A solution to your problem is having 2 diferent divs for, 1 for your night scene, and other for your sunny sky just in the same position, one over the other and with the sunny one with a higher z-index.
Then what you need to animate on scroll is the opacity of the sunny sky, what makes the night scene appear.
Also I found that your level of scroll isn't enough to fade the opacity of the sunny sky completly, it ends in 0.603448.
Hope it helps, please tell me if this worked.
As stated already, background images can't be animated, only background colors. So you'll have to lay both images on top of each other and fade the top layer in like this -
*Untested
#starynight-wrap {
position: relative;
width: 100%; height: 307px;
}
#starynight-day {
position: relative;
width: 100%; height: 100%;
background: url('images/sunny.jpg');
background-size: cover;
}
#starynight-night {
position: absolute;
top: 0; left: 0;
width: 100%; height: 100%;
background: url('images/night.jpg');
background-size: cover;
}
<div id="starynight-wrap">
<div id="starynight-day"></div>
<div id="starynight-night"
data-bottom-top="opacity: 0"
data--50-top="opacity: 0;"
data--60-top="opacity: 0.5;"
data--70-top="opacity: 1;"
>
</div>

I'm looking for a way to darken all of the area within a container except for a transparent child div. This div is draggable, so the dimmed area would have to move with it. Does anyone know of a way to achieve this using jQuery/CSS? Here is a picture of the effect I am trying to achieve:
EDIT: SOLVED
See #Robby Cornelissen's answer
Could do something like this fiddle. It relies on an absolutely positioned viewport element with a fixed background. If you click the viewport element, you'll see that it moves while the background stays fixed.
HTML
<div class="back">
<div class="overlay">
<div class="front">
</div>
</div>
</div>
CSS
.back, .front {
background-image: url("http://upload.wikimedia.org/wikipedia/commons/thumb/5/51/Swallow_flying_drinking.jpg/1024px-Swallow_flying_drinking.jpg");
background-attachment: fixed;
background-position: 0,0;
}
.back {
width: 1024px;
height: 623px;
}
.front {
position: absolute;
left: 200px;
top: 50px;
width: 300px;
height: 150px;
z-index: 100;
}
.overlay {
width: 100%;
height: 100%;
background-color: rgba(0,0,0,0.5);
}
PROBLEM SOLVED
I'm working on a personal website and my background image won't appear, I am using a JavaScript code to change my background color from time to time and my default background-image is set to a color so my the first second of website won't appear white. Could that be the problem of my image not appearing?
This is part of my html code:
<!doctype html>
window.onload = function() {
var currentColor = '#61a18e';
setInterval(function() {
document.body.style.backgroundColor = currentColor;
currentColor = currentColor === '#dd9023' ? '#61a18e' : '#dd9023';
}, 10000);//
};
</script>
</head>
<body>
<div id="wrapper">
<div class="nowplaying">
Text
</div>
<div class="song">
TExt
</div>
</div>
</body>
</html>
And this is a part of my css code including html, body and the main wrapper container(if it helps for some reason):
html, body{
width:100%;
height:99%;
position: relative;
margin: auto;
background-color:#61a18e;
-webkit-background-size: cover;
-moz-background-size: cover;
background-size: cover;
background-image:url ('img/background.png');
}
#wrapper{
position:absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
position:absolute;
width: 50%;
height: 40%;
overflow: auto;
}
Hope I'm not missing anything here.
Thanks
EDIT :
Interesting my code on JSFiddle is working....
But none of my browser (Mozilla and IE9) is showing any image,but if i insert it with the image is showing...
Is there some settings to browser not showing?
NEW EDIT!
Problems solved, silly for me, but it looks like I should have put background-image:url ('../path');, for some reason it won't take without the ../.
Thanks for the help.
It’s the extra space between "url" and the parenthesis.
background-image:url ('img/background.png');
Becomes
background-image: url('img/background.png');
Remove the space between url ('image.jpg').
Also, it's going to duplicate when you get it to work, for HTML and Body elements.
You are setting some colours via the tag. If they are for background and if you load the css file before it, the script will override it.
Here you go: http://jsfiddle.net/g8Jhe/1/
CSS
html,body
{
width:100%;
height:99%;
position: relative;
margin: auto;
background-color:#61a18e;
-webkit-background-size: cover;
-moz-background-size: cover;
background-size: cover;
background-image:url('https://www.google.com/images/srpr/logo11w.png');
background-repeat: no-repeat;
margin: 0px;
padding: 0px;
}
I have large images of varying dimensions that need to completely fill 240px by 300px containers in both dimensions. Here is what I got right now, which only works for one dimension:
http://jsfiddle.net/HsE6H/
HTML
<div class="container">
<img src="http://placehold.it/300x1500">
</div>
<div class="container">
<img src="http://placehold.it/1500x300">
</div
CSS
.container {
height: 300px;
width: 240px;
background-color: red;
float: left;
overflow: hidden;
margin: 20px;
}
img {
max-width: 100%;
height: auto;
}
The proportions should stay the same. Essentially, wide images should be cut off in width, while high images need to be cut off in height. So just zooming in as much as is needed to fill the container.
Not sure why I can't get it to work, do I need JavaScript for this?
Edit: To be clear. I need everything red on the fiddle gone. The images coming in are dynamic, therefore I can't use background-images. I'm open to using JavaScript. Thanks! :)
Auto-sizing Images to Fit a Div - Making the CSS Work
Here is one way of doing it, start with the following HTML:
<div class="container portrait">
<h4>Portrait Style</h4>
<img src="http://placekitten.com/150/300">
</div>
and the CSS:
.container {
height: 300px;
width: 240px;
background-color: red;
float: left;
overflow: hidden;
margin: 20px;
}
.container img {
display: block;
}
.portrait img {
width: 100%;
}
.landscape img {
height: 100%;
}
and the demo fiddle: http://jsfiddle.net/audetwebdesign/QEpJH/
When you have an image oriented as a portrait, you need to scale the width to 100%. Conversely, when the image is landscape oriented, you need to scale the height.
Unfortunately, there is no combination of selectors in CSS that targets the aspect ratio of the image, so you can't use CSS to pick out the correct scaling.
In addition, you have no easy way of centering the image since the top left corner of the image is pinned to the top left corner of the containing block.
jQuery Helper
You can use the following jQuery action to determine which class to set based
on the aspect ratio of the image.
$(".container").each(function(){
// Uncomment the following if you need to make this dynamic
//var refH = $(this).height();
//var refW = $(this).width();
//var refRatio = refW/refH;
// Hard coded value...
var refRatio = 240/300;
var imgH = $(this).children("img").height();
var imgW = $(this).children("img").width();
if ( (imgW/imgH) < refRatio ) {
$(this).addClass("portrait");
} else {
$(this).addClass("landscape");
}
})
For each image in .container, get the height and width, test if width<height and then set the appropriate class.
Also, I added a check to take into account the aspect ratio of the containing block.
Before, I had implicitly assumed a square view panel.
For anyone looking to do this that doesn't have dynamic images, here's an all-CSS solution using background-image.
<div class="container"
style="background-image: url('http://placehold.it/300x1500');
background-size: cover; background-position: center;">
</div>
<div class="container"
style="background-image: url('http://placehold.it/1500x300');
background-size: cover; background-position: center;">
</div>
The "background-size: cover" makes it so that the image scales to cover all of the div while maintaining the aspect ratio. The CSS could also be moved to a CSS file. Although if it's dynamically generated, the background-image property will have to stay in the style attribute.
Taking out the line: max-width:100% in your CSS file seems to do the trick.
.container {
height: 300px;
width: 240px;
background-color: red;
float: left;
overflow: hidden;
margin: 20px;
}
img {
height: auto;
}
Also you can add > to your closing div in your HTML file could make the code neater.
<div class="container">
<img src="http://placehold.it/300x1500">
</div>
<div class="container">
<img src="http://placehold.it/1500x300">
</div>
Here is a working JSFiddle link: http://jsfiddle.net/HsE6H/19/
Here is another solution I found, that no need to seperate portraid or landscape or scripting.
<div class="container">
<img src="http://placehold.it/500x500" class="pic" />
</div>
CSS
.container{
position: relative;
width: 500px;
height: 300px;
margin-top: 30px;
background: #4477bb;
}
.pic{
max-width: 100%;
width: auto;
max-height: 100%;
position: absolute;
left: 0;
right: 0;
top: 0;
bottom: 0;
margin: auto;
}
Here it is, it works well...
https://jsfiddle.net/efirat/17bopn2q/2/
Background can do this
set image as background
2.
div {
-webkit-background-size: auto 100%;
-moz-background-size: auto 100%;
-o-background-size: auto 100%;
background-size: auto 100%;
}
or
div {
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
You should try this:
img {
min-width:100%;
min-height:100%;
}
I used this plugin that accounts for any ratio. It also requires imagesloaded plugin to work. This would be useful for numerous images across a site needing this treatment. Simple to initiate too.
https://github.com/johnpolacek/imagefill.js/
It works if you add the following to the parent div for img styling;
https://jsfiddle.net/yrrncees/10/
.container img {
position: relative;
vertical-align: middle;
top: 50%;
-webkit-transform: translateY(-50%);
min-height: 100%;
min-width: 100%;
object-fit:cover;
}
This could do the job:
.container {
float: left;
height: 300px;
width: 240px;
background-color: red;
margin: 20px;
}
img {
width:240px;
height:300px;
}
We went down the path with an Angular app of using a variation on the jQuery approach above. Then one of our bright colleagues came up with a pure CSS approach. See this example here: https://jsfiddle.net/jeffturner/yrrncees/1/.
Basically using line-height solved the problem for us. For those not wanting to hit the fiddle, the code fragments are:
.container {
margin: 10px;
width: 125px;
height: 125px;
line-height: 115px;
text-align: center;
border: 1px solid red;
}
.resize_fit_center {
max-width:100%;
max-height:100%;
vertical-align: middle;
}
The key is in using line-height and setting the container to do the same.
I came across this topic because I was trying to solve a similar problem. Then a lightbulb went off in my head and I couldn't believe it worked because it was so simple and so obvious.
CSS
.container {
height: 300px;
width: 240px;
background-color: red;
float: left;
overflow: hidden;
margin: 20px;
}
img {
min-width:100%;
min-height:100%;
}
Just set the min-width and min-height to 100% and it will always automatically resize to fit the div, cutting off the excess image. No muss no fuss.
Using an image as Div background has many disadvantages (like missing ALT for SEO). Instead of it, use object-fit: cover; in the image tag style!
The following solution is very short and clean if you need to insert img tag into div tag:
.container, .container img
{
max-height: 300px;
max-width: 240px;
}
Try to open every image into another page you will notice that originals are all different sized but none is streched, just zoomed:
<p></p>
<div class="container"><img src="https://www.gentoo.org/assets/img/screenshots/surface.png" /></div>
<p></p>
<div class="container"><img src="https://cdn.pixabay.com/photo/2011/03/22/22/25/winter-5701_960_720.jpg" /></div>
<p></p>
<div class="container"><img src="https://cdn.arstechnica.net/wp-content/uploads/2009/11/Screenshot-gnome-shell-overview.png" /></div>
<p></p>
<div class="container"><img src="http://i.imgur.com/OwFSTIw.png" /></div>
<p></p>
<div class="container"><img src="https://www.gentoo.org/assets/img/screenshots/surface.png" /></div>
<p></p>
<div class="container"><img src="https://freebsd.kde.org/img/screenshots/uk_maximignatenko_kde420-1.png" /></div>
<p></p>
<div class="container"><img src="https://i.ytimg.com/vi/9mrOgkYje0s/maxresdefault.jpg" /></div>
<p></p>
<div class="container"><img src="https://upload.wikimedia.org/wikipedia/commons/5/59/Linux_screenshot.jpg" /></div>
<p></p>
Also, if you don't need to use a div you can just write an even shorter css:
img
{
max-height: 300px;
max-width: 240px;
}
