why I cannot change my background for a div - css

This is my coding, I want to change my background-image, but it seems not working.
I have tried this coding, it is not working, i don't know what's wrong.
<header style="background-image:url('C:/Documents and Settings/Administrator/desktop/images/navigationBackground.jpg')"></header>

Because you are using full path of file instead of URL.
Change url to http://localhost/images/navigationBackground.jpg, or better without server name, just relative url images/navigationBackground.jpg (and move image to web accessable location instead of desktop)

you have to specify the url of the image, instead of the filesystem path

You should restructure your webpage path. You can put all your resources in a single folder and just specify the url of your image, instead of using filesystem path.

Unable to add bgimage in CSS

The below is my piece of code, I am not able to add background-image in my web page, can anyone tell me where I am going wrong?
enter image description here
Create folder called 'images' near your class_id.html file are located and Copy "Aravind_Signature.jpg" image to the newly created image folder
and then change the css background-image property as below
background-image:url("images/Aravind_Signature.jpg");
Note : its bad approach for referring image files path starting from drive names like "c:\". Because when you share your code you need change image path always.
There is nothing wrong, you just need to look at referring to path this way...
either use '/' or '\' so that you will get the right path.

convert a jpeg into url for css

I am new to web design and I think I need to convert a jpeg into a url. I have an image saved locally on my computer. An example website that I am using as a reference has a one page for their html/source code and a different page for their css. All of the images are listed under the css page, however, they are typed in as a url. For example url(..green sea.jpeg) When I try to replace their css code with my image, it can't be found. I know I'm new, so I figure I must be making a simple simple mistake, but everytime I try and look it up online, I find directions on how to convert a jpeg into a url and it looks like you need another kind of software to do this, but I'm not exactly sure. Any help/direction would be very much appreciated!
Thanks!
When you replace your image name for the one you see in the CSS:
url(..green sea.jpeg)
...make sure that the image you are wanting to use is in the same location (folder / place) as the green sea image.
So if I want to replace it:
url(..myNewimage.jpeg)
I would make sure it was in the same place as the image I'm replacing it with.
ALSO, I just noticed that your path is wrong. You have ".." when it should probably be "../".
So try this:
url(../green sea.jpeg)
The url you need for your code is just wherever you have posted the image on your server in relationship to the css file. For example, if your directory is structured like this:
/CSS
-style.css
/JS
/images
-green-sea.jpg
index.html
Then your url would be (../images/green-sea.jpg)

DRUPAL broken images after enabling url rewriting

I turned on URL rewriting on Drupal, and some URL image are broken.
For example :
local/tw/sites/all/themes/tw/images/1-p1.jpg become
local/tw/content/sites/all/themes/tw/images/1-p1.jpg
or
local/tw/sites/all/themes/tw/images/2-p1.jpg become
local/tw/node/sites/all/themes/tw/images/2-p1.jpg
Any ideas?
If you used relative path, and you're talking about contents within nodes, it's perfectly normal, since "node/" is interpreted like a directory.
You could fix this problem adding a "/" before image src, or using module like Path Filter that provides a simple file:relative/path/to/file syntax.

CSS background-image won't show with short URL

I've done my searching and the topics haven't been of help.
I'm trying to have the background image of my header repeat across the X axis of the header div.
When I make CSS with a long URL such as
background-image:url('http://site.com/images/logo.png'); everything works fine
When I try to shorten the CSS to something such as ~/images/ or even having the CSS and site file already in the root folder and using /images/ I get nothing
background-image:url('~/images/logo.png')
background-image:url('/images/logo.png')
This is possibly because you're not shortening your URLs appropriately.
Assuming an absolute path of:
url('www.example.com/images/imageName.png');
A root-relative URL would be:
url('/images/imageName.png');
And a relative path (assuming your CSS file is in www.example.com/css/cssStylesheet.css) would be:
url('../images/imageName.png'); /* parent directory, then the images directory */
The ~ prefixed url format is unknown to me, though I suspect it's an ASP, or .NET, form? Though I'm unable to advise on that.
Questions that might be of use to you:
How do I turn a relative URL into a full URL?
Using relative URL in CSS file, what location is it relative to?
Absolute urls, relative urls, and...?
A URL containing "~" is something that's specific to ASP.NET, it's processed server-side and transformed into a "proper" URL such as http://mysite/my_virtual_directory/images/logo.png. Web Browsers don't have any way to do this as they don't know to what "~" refers.
You need to ensure that the URLs you use in your CSS file are "understandable" by the browser, so either have them "fully qualified" (http://mysite/my_virtual_directory/images/logo.png) or starting from the "beginning" (/my_virtual_directory/images/logo.png).

How do I set a CSS url to an absolute location?

I'm working on an HTML5 mobile app and I initially have the background of a DIV item set through the CSS as follows:
background-image: url('images/ClanSpider.png');
In my app, I have a method that changes the background DIV based on a selection made in a dropdown list from a previous method using jQuery:
function ResetMyHonor()
{
ClanImage = 'images/Clan' + MyClanName + '.png';
$("#MyClanName").html(MyClanName);
$("#MyHonorBox").css('backgroundImage', 'url(' + ClanImage + ')');
}
All of this works fine when I'm on the root of my page. However, I have some links within the app using hash tags to navigate the page (such as #MyHonor). When I've navigated to one of these tags and call my reset function above, the image breaks. When I pull up the Chrome Inspector to look at the DIV tag, it says that the image it is trying to load is "images/MyHonor/ClanSpider.png" which doesn't exist.
I know the CSS url will generate links in reference to its location within the application, but it doesn't matter where I move the CSS files in the application.
Is there a way for me to rewrite what comes out of the url processing or an alternate way of specifying the background image of the DIV without doing any kind of server side processing? Ideally this app will run through the manifest cache feature of HTML5, so I won't have access to any server based languages.
Try putting a leading slash on those paths to represent the root.
ie use:
url('/images/ClanSpider.png')
instead of
url('images/ClanSpider.png')
From reading through your comments on the other answers I think you're creating a problem for yourself that doesn't really exist. If url('/images/ClanSpider.png') is going to work when you upload to the web server then the trick is to make it work the same way when working locally. By far the easiest way to do this, especially if your focus is an offline app which has little in the way of server side requirements (which I'm assuming is true, as you mentioned file:/// URIs), is to run a local web server.
Python ships with a module SimpleHTTPServer, if you have Python installed then starting it is as simple as going to your L5RHonor project directory in a command prompt and issuing the following command:
python -m SimpleHTTPServer
Then instead of accessing your files with URIs like this:
file:///H:/Projects/L5RHonor/images/ClanSpider.png
You will access them like this:
http://localhost:8000/images/ClanSpider.png
All your root relative file paths will now work correctly, as an added bonus the offline caching will work correctly in Chrome and you'll be able to see from the log in the command prompt window that it is requesting and caching the correct files according to your manifest.
The simplest solution is obviously adding a slash to the URL to make it absolute. That will work fine, but it makes it impossible to move the application into a sub-directory, or to move static resources to a different server. If that is a problem, there are various alternative ways.
If the number of possible background images is finite, you could define every one in a class of its own:
.bgSpider { background-image: url('images/ClanSpider.png'); }
.bgFalcon { background-image: url('images/ClanFalcon.png'); }
...
and then do an .addClass() to set the correct image.
Other than that, as far as I know, there is no way to specify a path relative to the style sheet (rather than the current document) when setting a background image path in Javascript. You would have to work with absolute paths, or define a root path in JavaScript, and use that:
// in the script head
imageRoot = "http://www.example.com/mysite/images";
// later....
$("#MyHonorBox").css('backgroundImage', 'url(' + imageRoot + ClanImage + ')');
The location of the CSS file is irrelevant, you are modifying the .style property of an HTML element. This is the same as using the style attribute.
As this is CSS embedded in the document, all URIs are relative to the document.
You probably want to start the URL with a /, or if you really want the absolute location specified in your question: http://
Try adding a / at the start of the URL?
