Have a variable in images path in Sass?

Question

I want to have one variable that contains the root path to all my images in my CSS file. I can't quite figure out if this is possible in pure Sass (the actual web project is not RoR, so can't use asset_pipeline or any of that fancy jazz).

Here's my example that doesn't work. On compile it balks at first instance of variable in the background url property saying ("Invalid CSS after "..site/background": expected ")").

Defining the function to return the path:

//Vars $assetPath : "/assets/images";  //Functions @function get-path-to-assets($assetPath){   @return $assetPath; } 

Using the function:

body {   margin: 0 auto;   background: url($get-path-to-assets/site/background.jpg) repeat-x fixed 0 0;   width: 100%; } 

Any help would be appreciated.

Answer 1

Have you tried the Interpolation syntax?

background: url(#{$get-path-to-assets}/site/background.jpg) repeat-x fixed 0 0; 

Answer 2

No need for a function:

$assetPath : "/assets/images";  ...  body {   margin: 0 auto;   background: url(#{$assetPath}/site/background.jpg) repeat-x fixed 0 0;   width: 100%; } 

See the interpolation docs for details.
