I generated a CSS Spritesheet with the help of a Texture packer and its looks like
.pirateSlotSprite {display:inline-block; overflow:hidden; background-repeat: no-repeat;background-image:url(../img/pirateSlotSprite.png);}
.backgroundps {width:800px; height:480px; background-position: -105px -304px}
.balanceBlockps {width:122px; height:61px; background-position: -0px -0px}
...more classes for each frame...
.lineControlps {width:113px; height:65px; background-position: -580px -0px}
.maxBetButtonps {width:115px; height:64px; background-position: -348px -0px}
Then I apply the classes pirateSlotSprite and backgroundps to a div (sav bgDiv) to display the background frame from the sprite sheet. Everything is fine upto this point.
bgDiv will get resized when the browser gets resized, but the background picture remained static without getting shrinked/enlarged to fit bgDiv.
So I added background-size:100% to pirateSlotSprite, but the sprite gets shifted to a different position. I guess the whole image gets shrinked first and then background-position:-105px -304px gets applied without the position values being scaled. If needed I will share the pictures to make the problem easier to understand.
Any ideas on how to fix this?
You misunderstand the way background images work. Positioning for background-images work with either pixels or percentages. But the images themselves are displayed in their true resolution and aspect ratio (unless altered by JavaScript). So they won't 'scale/stretch' when you resize the browser window.

I'm using a template from semantic-ui. This one: https://semantic-ui.com/examples/homepage.html. Essentially i'm trying to change the height of the background to match the height of my image. Right now my image (the one in background-image) shows up but the background (which I turned red simply to see it better) is larger then it so I have this dead space between my background-image and the beginning of the content.
The only way I seem to be able to manipulate the background is the color. Any other time i'm changing it's size (which i've experimented with quite a bit) it only seems to change the size of the image. Not the red background.
Perhaps i'm not understanding the relationship between the two? Any tips on how to change the background's height to match the background-image?
Any help is appreciated.
CSS below:
.ui.inverted.vertical.center.aligned.segment {
background: red;
background-image: url('./images/backgroundLogo.png');
background-repeat: no-repeat;
/* background-size: 100%; */
background-size: 100% 507px;;
width:100%;
}
I found it. There was a native min-height: property that was over riding my attempts to change. Simply put in
min-height: 500px !important;
and it worked.
I hope this is simple but here is the code I'm doing and it works perfectly except for one thing, the scale isn't kept. It gets wide and then looks silly.
.div1 {
background-image: url("images/headerbgimage2.jpg");
background-repeat: no-repeat;
background-size: 100% 100%;
background-position: center center;
}
The image scales when resized and on smaller sizes it looks normal but as it gets bigger (wider) it stretches and looks awkward. How can I make it so the image keeps its aspect and just "zooms" in on itself keeping the whole div covered and the image scaled.
An example of this working on a site is techhubdenver .com with their top div background image
Can this be done with CSS or will I need to get some Javascript coding going to do this.
I know how to make new images for responsive type pages but I was hoping to just use one image and have it work no matter the device. it only becomes a problem when the screen size is way off from the image size (too small or too wide).
if the image would just "shrink" but keep aspect ratio for smaller devices I think it would work and if the image would just "zoom in" staying on the center of the image when the screen size gets to large i think it would work good.
Keep aspect ratio and always fill the div (okay to zoom in) is my goal here.
You need background-size: cover;. That will scale your background such that it covers the element.
.div1 {
background-image: url("images/headerbgimage2.jpg");
background-repeat: no-repeat;
background-size: cover;
background-position: center center;
}
My website has the following CSS making an image stick to the bottom of the site.
#wrapper{
min-height:100%;
background:#fff url(grafikk/bg-footer.gif) no-repeat 50% 100%;
width:100%;
overflow:hidden;
}
It words great - the picture is centered and stick to the bottom of the page.
But I'd like to set the picture width to 50% of the original PNG. The PNG is 640px wide, so setting it to 320px is also ok.
How could I do that?
(I was unable to find what the different properties of the background-setting actually mean.)
You can actually use pixel values in background-size:
background-size: 320px 100%;
I believe the property you're looking for is the background-size. More info here: http://www.w3schools.com/cssref/css3_pr_background-size.asp
I have been using css for a few years but have never ventured past using fixed width layouts. I'm looking at using a fluid layout for my next site, or as much percentage as I can, but I have a question that worries me.
If I have an image with 1900px width set as a background, I understand that it simply shrinks when the browser calls for say 1600px.
What happens when the resolution calls for a 2000px width? I will be left with white space, correct? How can one avoid this? I feel like I should probably just throw out that its not an image that can be repeated horizontally.
A trick usually used is to have the image be "inner-glowed" with a color, then set the background color the same as well.
Suppose your image doesn't tile, and has black "inner-glow" or "feather" effect, then you can make the container's background color as such:
background-color: #000;
background-image: url(your_bgimage.jpg); /* image with black borders due to effect */
background-repeat: no-repeat;
background-position: center center;
So I have a div with a background image. I would like the background image to always be 100% on the screen no matter what the screen size is. I would like the image to grow in proportion but crop the height. I don't want the image to stretch. What I have so far is:
#banner {
background:url(../images/blurry.jpg) no-repeat;
width:100%;
height:520px;
background-size:100% 100%;
}
At the moment this is stretching the image to 100% and making the image look stretched.
Can anyone help me with this or point me in the right direction?
Use the CSS3 background-size property. Set it to cover. Like so:
background-size: cover;
Note that only IE9 and later supports this property value. IE8 will complain about an unsupported value. Chrome and Firefox supported cover since the past couple of years at least.
