Relative path to a stylesheet in Visual studio not working in preview

Question

Hi,

I'm assuming this is an easy question, but I'll be darned if I can find the answer.

I have a website in Visual Studio 2008. The paths to the stylesheets (and images) are in the following format /css/stylesheetname.css

At the root of the web project in Visual studio the folder exists as does the stylesheet. These paths work fine when running it in IIS.

If I use the inbuilt webserver in Visual Studio the paths fail because it puts the projectname in the path i.e. http://localhost:2020/projectname/default.aspx

In this case the / takes the path right back to http://localhost:2020

This is further compounded by the fact that if you click "design" the styles that import background images all fail although the stylesheet is imported correctly (becuase all other aspects of the stylesheet work i.e. .class{font-family:arial;} works but .class{background: url(/images/image.jpg)} does not).

I guess it's all to do with how Visual studio calculates its root path for the website, however I can't find a setting to change this.

Any ideas?? Update: as per Egil Hansen's answer I converted the paths in the CSS file to relative paths. However the background images still do not display in Design mode. I'll take a look at using Themes to get round this in due course.

Answer 1

it has been ages since I did anything in css, but maybe url(./images/image.jpg) will work?

Edit: Or rather ~/format /css/stylesheetname.css or ./format /css/stylesheetname.css as the url to the stylesheet.

Answer 2

I think the correct solution is to use relative urls in the style sheet instead of absolute urls as you use now.

Do note that relative urls in style sheets are relative to the location of the style sheet, not the current page being view by the browser.

If you use ASP.NET Themes, you can put all your website graphics in a /App_Themes/YourTheme/Images/ folder, and put your style sheet in the /App_Themes/YourTheme/ folder.

In your style sheet, you can then simply reference an image with url(Images/img.gif), and it will work both online and in development.

The you just need to assign your ASP.NET Theme to the page(s) you want, either through web.config's Pages section (<pages styleSheetTheme="Default">) that will assign a theme to all pages on the website or through the <%@ Page ... directive on each page.

In general, you can do some really neat things with ASP.NET Themes and Skins, just take a look at the ASP.NET Themes and Skins Overview over at msdn.microsoft.com.

There are a few issues to be aware of with Themes in ASP.NET, take a look at my post How to take control of style sheets in ASP.NET Themes with the StylePlaceHolder and Style control, which explains and solves the issues I have come across so far.

Answer 3

I had the same issue and it drove me crazy. Solution is to add an Apps_Theme folder and copy the images into there. When you publish the site the folder structure is preserved and the imnges display.

Answer 4

I had set path css url image by code { background:url(/images/xxx.jpg) no-repeat; } and running file at IIS, so must to point default website to your project

how to running testing preview type: http://localhost/default.aspx

this is correct path same running on server include file js or css can use "/" root path
