3 different backgrounds with CSS - html

I'm wondering if the following is possible with CSS.
I'd like there to be 3 horizontal bars running across the entire width of a background. Here's a rough mockup of what I would like the background to be
I've been toying with the following but I can't seem to be able to position any of the backgrounds.
#blog {
width: 1200px;
height: 100%;
background-image: url("bg1.png"),
url("bg2.png"),
url("bg3.png");
background-position: 10px 10px,
170px 10px,
750px 10px;
background-repeat:repeat-x;
}
Here's a fiddle: http://jsfiddle.net/5fo054L2/1/
Any idea what I'm doing wrong?

You almost have it. The issue is that you have the x and y position confused. Also, x position doesn't have any meaning if it repeats.
.blog {
width: 100%;
height: 100%;
background-image: url("http://i.imgur.com/L3F9slr.png"), url("http://i.imgur.com/rmPDxMq.png"), url("http://i.imgur.com/9MMzDMs.png");
background-position: 0px 170px, 0px 100px, 0px 10px;
background-repeat: repeat-x;
}
Here is an updated jsfiddle: http://jsfiddle.net/5fo054L2/3/
Note that the vertical height (of text in your example) will limit the amount of the background images you see.

You can also make three image files, place them below everything else, and set them using absolute positioning.

how to remove white border from sprite image

I just begun to learn how to use image sprites in order to optimize my site better. However, there is this white border on the right and bottom side of my image element. I searched for posts on here and google and cannot seem to figure out how to remove the border.
I did read it was caused by using the image element, however, I need to use this element for SEO purposes. By using a div it would cripple my SEO in regard to images (from what I have read anyways). Can anyone help me figure this out? It did this in both Chrome and Firefox. Thank you
[White border on right and bottom of image container][1]
<img class="image-sprite" src="">
.image-sprite {
background: url("../images/gallery-sprite.png");
background-color: #3a3a3a;
background-position: -17px -10px;
background-repeat: no-repeat;
width: 360px;
height: 470px;
}
Are you able to put the background URL directly into the img tag in HTML? Like this:
.image-sprite {
background-color: #3a3a3a;
background-position: -17px -10px;
background-repeat: no-repeat;
width: 360px;
height: 470px;
}
body{
background-color: gray;
}
<img class="image-sprite" src="https://w3schools.com/html/img_girl.jpg">
I've posted an example below, see can you find any white space on either side? The problem might be the 'image-size' you using and dimensions that you are placing your image with. If your image finishes by the time it reaches the right end or bottom end, obviously then and only then you'll see the white space, otherwise there is no issue in using sprites. Either increase your image in size, or decrease its width and height.
.image-sprite {
background: url("https://picsum.photos/200/300");
background-position: -10 -10px;
background-repeat: no-repeat;
width: 100px;
height: 100px;
}
<img class="image-sprite">

Is background: no-repeat; needed when you have a fixed sized image?

Is background: no-repeat; needed when you have a fixed image?
I read that, when put any background image, it's getting repeated by default.
Even when you don't see it on the screen, is it sill getting repeated then, even on a fixed image?
Do you need to specify no-repeat regardless?
The image size is 180 x 180.
<style>
#playButton4 {
border: 3px solid #0059dd;
width: 260px;
height: 194px;
cursor: pointer;
background-color: black;
}
.img2 {
background: url(https://i.imgur.com/4HJbzEq.png);
background-repeat: no-repeat;
width: 180px;
height: 180px;
margin: 7px 40px;
}
</style>
<div id="playButton4" onclick="">
<div class="img2"></div>
</div>
background-repeat property is relevant whenever the size of the element exceeds the size of background-image. If this never happens to your element, specifying background-repeat is dead code.
If, under any circumstance, your element might become larger than the background-image (on either direction) and you don't want the image repeated, you should leave it in.
As a side note, background is a shorthand property which includes background-repeat, thus:
background: url(https://i.imgur.com/4HJbzEq.png) no-repeat;
being an exact equivalent of
background-image: url(https://i.imgur.com/4HJbzEq.png);
background-repeat-x: no-repeat;
background-repeat-y: no-repeat;
, which reduces your "dead code" to only 10 characters.
I think you need it to avoid repeated image, Your image does not repeat because you set your with same with your image resolution, How if you set your width 100% and not using background-repeat: no-repeat;, You will get repeated image.
Yes, it's best to use ,no-repeat unless you want to tile your background images to make background patterns or make background responsive.
Refer: https://blogs.adobe.com/creativecloud/best-practices-for-background-images-your-getting-started-guide/
In your case, you need not use no-repeat as you have given a fixed dimension(same as the image dimension) to your container <div> . Later, If you wish to change(increase) the dimensions of the container dynamically to make it responsive, then you would definitely need no-repeat .

How to make background sprite responsive and only show half the height?

Probably one of the most documented subjects and yet I can't seem to find a proper answer for what I'm trying to get accomplished.
I have a sprite containing two images on top of each other. I only want to show the green one and have it be responsive at the same time. It is the background image of the whole page.
Please see: http://demo.chilipress.com/epic3/
I've given it a height: 900px because that's half of the height of the full img. I know it's not responsive as it is now.
HTML:
<div id="background_contact"></div>
CSS:
#background_contact{
background-image: url('bg_contact.jpg');
width:100%;
height: 900px;
background-position: 0 0;
background-size: 100%;
display: block;
}
An example is to have a hover effect on it, but you get the idea.
#background_contact:hover {
background-position: 0% 100%;
}
If you don't mind the stretch, you can adjust your CSS to cover everything.
#background_contact {
background-size: 100% 200%;
}
If you don't want it to stretch, you can use the following CSS, though you may want your own background color filler for the gaps:
#background_contact {
background-size: auto 200%;
background-position: 50% 0;
}
#background_contact:hover {
background-position: 50% 100%;
}

DIV background image being cut off when zoomed out in firefox

I have a DIV with height/width of 15px.
It has a background image also with height/width of 15px.
The problem is the background image is being cut off a few pixels on right and bottom when zoomed out some levels in firefox.
Here's a link and code below. Try viewing it in firefox.
<div id="custom-checkbox"></div>
#custom-checkbox
{
background: url('http://s16.postimg.org/5xacziapd/unchecked.png') no-repeat;
width: 15px;
height: 15px;
}
This is the best I can get it to display the rest is just firefoxes pixel rounding.
#custom-checkbox
{
background: url('http://s16.postimg.org/5xacziapd/unchecked.png') no-repeat;
width: 15px !important;
height: 15px !important;
display:table;
}
Hope this helps it's the best I could do.

CSS background image to fit width, height should auto-scale in proportion

I have
body {
background: url(images/background.svg);
}
The desired effect is that this background image will have width equal to that of the page, height changing to maintain the proportion. e.g. if the original image happens to be 100*200 (any units) and the body is 600px wide, the background image should end up being 1200px high. The height should change automatically if the window is resized. Is this possible?
At the moment, Firefox looks like it's making the height fit and then adjusting the width. Is this perhaps because the height is the longest dimension and it's trying to avoid cropping? I want to crop vertically, then scroll: no horizontal repeat.
Also, Chrome is placing the image in the centre, no repeat, even when background-repeat:repeat is given explicitly, which is the default anyway.
There is a CSS3 property for this, namely background-size (compatibility check). While one can set length values, it's usually used with the special values contain and cover. In your specific case, you should use cover:
body {
background-image: url(images/background.svg);
background-size: cover; /* <------ */
background-repeat: no-repeat;
background-position: center center; /* optional, center the image */
}
Eggsplanation for contain and cover
Sorry for the bad pun, but I'm going to use the picture of the day by Biswarup Ganguly for demonstration. Lets say that this is your screen, and the gray area is outside of your visible screen. For demonstration, I'm going to assume a 16x9 ratio.
We want to use the aforementioned picture of the day as a background. However, we cropped the image to 4x3 for some reason. We could set the background-size property to some fixed length, but we will focus on contain and cover. Note that I also assume that we didn't mangle the width and/or height of body.
contain
contain
Scale the image, while preserving its intrinsic aspect ratio (if any), to the largest size such that both its width and its height can fit inside the background positioning area.
This makes sure that the background image is always completely contained in the background positioning area, however, there could be some empty space filled with your background-color in this case:
cover
cover
Scale the image, while preserving its intrinsic aspect ratio (if any), to the smallest size such that both its width and its height can completely cover the background positioning area.
This makes sure that the background image is covering everything. There will be no visible background-color, however depending on the screen's ratio a great part of your image could be cut off:
Demonstration with actual code
div > div {
background-image: url(http://i.stack.imgur.com/r5CAq.jpg);
background-repeat: no-repeat;
background-position: center center;
background-color: #ccc;
border: 1px solid;
width: 20em;
height: 10em;
}
div.contain {
background-size: contain;
}
div.cover {
background-size: cover;
}

Based on tips from https://developer.mozilla.org/en-US/docs/CSS/background-size I end up with the following recipe that worked for me
body {
overflow-y: hidden ! important;
overflow-x: hidden ! important;
background-color: #f8f8f8;
background-image: url('index.png');
/*background-size: cover;*/
background-size: contain;
background-repeat: no-repeat;
background-position: right;
}
Background image is not Set Perfect then his css is problem create so his css file change to below code
html {
background-image: url("example.png");
background-repeat: no-repeat;
background-position: 0% 0%;
background-size: 100% 100%;
}
%; background-size: 100% 100%;"
I'm not sure what you're looking for exactly, but you really should check out these excellent blog posts written by Chris Coyier from CSS-Tricks:
http://css-tricks.com/how-to-resizeable-background-image/
http://css-tricks.com/perfect-full-page-background-image/
Read the descriptions for each of the articles and see if they're what you're looking for.
The first answers the following question:
Is there a way to make a background image resizeable? As in, fill the background of a web page edge-to-edge with an image, no matter the size of the browser window. Also, have it resize larger or smaller as the browser window changes. Also, make sure it retains its ratio (doesn't stretch weird). Also, doesn't cause scrollbars, just cuts off vertically if it needs to. Also, comes in on the page as an inline tag.
The second post's goal is to get the following, a "background image on a website that covers the entire browser window at all times. "
Hope this helps.
Just add this one line:
.your-class {
height: 100vh;
}
vh is viewport height.
This will automatically scale to fit the device' browser window.
Check more here: Make div 100% height of browser window
body{
background-image: url(../url/imageName.jpg);
background-attachment: fixed;
background-size: auto 100%;
background-position: center;
}
Try this,
element.style {
background: rgba(0, 0, 0, 0) url("img/shopping_bgImg.jpg") no-repeat scroll center center / cover;
}
I had the same issue, unable to resize the image when adjusting browser dimensions.
Bad Code:
html {
background-color: white;
background-image: url("example.png");
background-repeat: no-repeat;
background-attachment: scroll;
background-position: 0% 0%;
}
Good Code:
html {
background-color: white;
background-image: url("example.png");
background-repeat: no-repeat;
background-attachment: scroll;
background-position: 0% 0%;
background-size: contain;
}
The key here is the addition of this element -> background-size: contain;
Here's what worked for me:
background-size: auto 100%;
width: 100%;
height: 100vh;
background: url("../img/hero-bg.jpg") top center;
background-size: cover;
background-repeat: no-repeat;
background-position: 0% 0%;
background-size: 100% 100%;
if you set min-height, for example:
min-height: 100vh;
You can use the below code to fit your background easily
body {
background: url(images/background.svg);
min-height: 100vh;
background-repeat: no-repeat;
background-size: cover;
}
Setting background size does not help, the following solution worked for me:
.class {
background-image: url(blablabla.jpg);
/* Add this */
height: auto;
}
It basically crops the image and makes it fit in, background-size: contain/cover still didn't make it fit.
