Heyya,
I've just started writing a website (I'm still pretty new to learning web dev) and I'm having issues with getting a background image to load on a website despite looking around and trying a bunch of different things.
.nav {
width: 100%;
background-image: url("../images/Shadex1.png");
background-repeat : repeat-x;
position : absolute ;
height: 50px;
left : 0;
top : 0;
}
The idea is to get the image to repeat and cover the nav bar and I've tried using both a png and svg files, but I just can't get it to work. I can load the images in the html file and that works fine so I know the file path is correct but CSS just isn't liking it so need a second pair of eyes to take a look.
Thank you for reading and any answers you might come up with.
Try to set width to 100vw and is the uri correct?
Make sure you are able to load the image background-image: url("../images/Shadex1.png"); property. I think there might be chances that url is wrong. if you are getting an image correctly than just see below example.
.nav {
width: 100%;
background-image: url("https://images.unsplash.com/photo-1657037031161-d126c02cce8c?ixlib=rb-1.2.1&ixid=MnwxMjA3fDB8MHxlZGl0b3JpYWwtZmVlZHw2fHx8ZW58MHx8fHw%3D&auto=format&fit=crop&w=500&q=60");
background-repeat: repeat-x;
position: absolute;
height: 100vh; /*I have added extra height for viewing image*/
left: 0;
top: 0;
}
<div class="nav"></div>

I am using html-pdf (https://www.npmjs.com/package/html-pdf) to generate PDFs based on HTML files.
I am now trying to add background images to these PDFs. One special/additional requirement is that the first page should have another background image than pages 2...n.
My attempt was to make use of the header feature, but the background images are never shown.
I added a header to the template, which is shown correctly, and tried to add a background image using the following CSS:
#pageHeader:after,
#pageHeader-first:after {
content: "";
display: block;
position: fixed;
bottom: 0;
right: 0;
top: 0;
left: 0;
height: 297mm;
width: 210mm;
background-image: url('/background-default.jpg');
background-repeat: no-repeat;
background-size: contain;
}
Just for reference, this is how I am adding the headers within the HTML file:
<div id="pageHeader">Test1</div>
<div id="pageHeader-first">Test2</div>
Any idea what I am doing wrong here?
Or is there a better way to achieve what I am looking for?
I found the solution for the problem:
Due to PhantomJS limitation, apparently I have to also add the images to the body and hide them using display: none;
Once that's done, the images will also show in the header/footer sections of html-pdf.

So for my website hostup I tried to add sprites since I had over 25 images and google pagespeed complained. I solved my sprire not displaying issue, but I am not sure why. Why is it that you have to load the image in each and everysprite, to waste bandwith and slow down pagespeed?
.sprite {
background-image: url(../img/spritesheet.png);
background-repeat: no-repeat;
display: block;
}
.sprite-backup_icon {
width: 60px;
height: 60px;
background-position: -5px -5px;
}
.sprite-cpanel_icon {
width: 60px;
height: 60px;
background-position: -75px -5px;
}
.sprite {
background-image: url(../img/spritesheet.png);
background-repeat: no-repeat;
display: block;
}
.sprite-backup_icon {
width: 60px;
height: 60px;
background: url(../img/spritesheet.png);
background-position: -5px -5px;
}
.sprite-cpanel_icon {
width: 60px;
height: 60px;
background: url(../img/spritesheet.png);
background-position: -75px -5px;
}
html code
<div class="sprite-backup_icon"></div>
So the 2nd. works just fine, but the 1st. does not display any image, Just a blank image with the defined width and height, why is this?
To answer your first question:
If the browser finds an image in a Style Sheet, it will download it and then store it in your browsers cache. The next time that same image is found/requested in a Style Sheet from the same URL (even during the same initial page load), it will be served from cache. NOT re-downloaded. So while you may have spritesheet.png 3 times in your Style Sheet, it is only downloaded once and not wasting bandwidth or page loading speed.
It is because of this caching feature that sprites are favoured in providing things like icons and other smaller images.
For your second question on why your first CSS example does not work, it could be any number of issues ranging from a simple typo, or all the elements you are wanting to use the sprite with not having the sprite class.
In order to properly help you with this problem, we need to see your HTML that goes along with the posted CSS. Please make an edit your question and add your HTML as a code snippet.
I have a background image of a paper airplane on the body tag of this page: http://cogo.goodfolk.co.nz. The very tip of it is being cut off - if you resize the browser window the full image pops back in.
It's only happening in Chrome, and isn't consistent, if you refresh sometimes, or even hover over sometimes it's fine. If I remove all the background styles (background position and no-repeat) then the whole image is there - but of course isn't positioned correctly. It's also happening on other pages of my website (eg http://cogo.goodfolk.co.nz/online-surveying).
After days of debugging/searching I can't find anything that refers to this issue and/or fixes it - is it possibly a Chrome bug with background-position?
Any ideas or workarounds? Thank you!
//EDITED//
The relevant code is pasted below, although obviously this is pretty standard so it must be something else in the site that's causing the problem:
.home {
background: url("../img/airplane.jpg") no-repeat center;
background-size: 70%;
background-position: 10% 98%;
}
The background image is set to center, so this is expected behaviour, depending on window size. You could change this CSS declaration from:
.home {
background: url("../img/airplane.jpg") no-repeat center;
background-size: 70%;
}
To:
.home {
background: url("../img/airplane.jpg") no-repeat center top;
background-size: 70%;
}
This would anchor the image to the top of the screen, meaning it would not clip, but this may not be the behaviour you are looking for.
To complicate matters, you also have this, which is probably contributing to the problem. I would suggest removing it entirely:
#media (min-width: 1200px)
.home {
background-position: 20% -10%;
}
Yay thanks to everyone who left suggestions, fortunately I've figured out a workaround! I managed to pretty much keep the background styles the same, and just placed everything in a :before pseudo element on the body tag. You can check out the updated code at cogo.goodfolk.co.nz if you're interested, or it's pasted here:
.home {
position: relative;
min-height: 860px;
}
.home:before {
content: "";
position: absolute;
width: 100%;
height: 100%;
background: url("../img/airplane.jpg") no-repeat center;
background-size: 70%;
background-position: 50% 15%;
}
Set the display to "inline-table".
I'm making a website with HTML5Boilerplate, but every time I use the css background or background-image property, the image doesn't show up.
Folders:
root/css/style.css
root/img_files/logo.png
My css code looks like this:
#logo {
position: absolute;
left: 20px;
top: 10px;
width: 164px;
height: 42px;
background: url(../img_files/logo.png);
background-repeat: none;
}
My stylesheet is properly added to the page:
I can't add a single background image to the objects on the page. HTML5Boilerplate has been installed, so maybe that't the problem, I'm not sure. Do you know why correct CSS and HTML doesn't display the images?
Change
background-repeat: none;
to
background-repeat: no-repeat;
Or just use
background: url(../img_files/logo.png) no-repeat;
I've just come to the same problem and discovered that in case you'll change ID from #logo to anything else (in HTML and CSS of course), then the same code will start to work. Can't say what has been "blocking" #logo to be used, but for now I don't have enough time to discover where the problem is.
Solution for now is to use anything else than #logo, eg. #logoTop or #siteLogo
Hope that helps.
EDIT: It was a selector typo problem which caused browser had ignored that. Weird was it had not happened when selector was changed to some other name than #logo. Please note that #logo:visible typo (instead of visited)
#logo, #logo:link, #logo:visited,
#logo:active, #logo:focus, #logo:hover
{
display: block;
width: 340px;
height: 150px;
background: url(../images/design-elements.png) 0 -300px no-repeat;
}
I had the same problem & found out that if without the width & height property, image will not display.
I'm creating my first Windows 8 app and I have a problem with CSS!
I have a folder images and background texture bg.png inside it. Also, stylesheet is in css folder.
CSS:
#contenthost {
height: 100%;
width: 100%;
background: url("../images/bg.png") repeat;
}
But nothing happen! I tried background: #999 which works. What should I do?
I tried your example with path to the image relative to the app root and it worked without any issues:
#contenthost {
height: 100%;
width: 100%;
background-image: url('/images/logo.png');
background-repeat: repeat;
}
In terms of your code this would be:
#contenthost {
height: 100%;
width: 100%;
background: url('/images/bg.png') repeat;
}
You can also save the image in your project folder.
And load it in the html page like this:
<img id="mainImg2" src="ms-appdata:///Local//bckgrnd.jpg" />
If it is not the path (using absolute vs. relative as above would fix that) you also need to make sure you have an element with an id = contenthost.
CSS let's you do both id and classes so if you start getting into styling page controls you will see a heavy use of classes like (.mypage .subsection).
Finally, you can always set the background in any individual html file directly on the body tag like:
<body style="background-image: url('/images/bg.png');">
