Can a shared image directory be established for LESS files?

Currently implementing the styling language known as LESS.

Take a look at the CSS below:

.side-bg
{
    background:url(../img/layout/side-bg.jpg) top no-repeat;    
}

At the moment, all images are stored in the directory ../img/. I wanted to set a variable for the image path and use it like this:

@image-path: ../img;

.side-bg
{
    background:url(@image-path/layout/side-bg.jpg) top no-repeat;   
}

Unfortunately, this method did not work. It's not a major issue, as I can always use find and replace if the image folder location changes. As someone new to LESS, I was curious if achieving something like this is possible.

Answer №1

Consider utilizing string interpolation when dealing with similar situations. Check out the documentation on "variable interpolation" at this link.

@main-url: "http://assets.example.com";
background-image: url("@{main-url}/images/background.png");

Answer №2

Here is the resolution:

.side-bg
{
    background : ~"url( '@{image-path}/layout/side-bg.jpg' )" top no-repeat;
}

Answer №3

After diligently searching for an answer to the same question, I stumbled upon this page and decided to share my solution in case it could help someone else...

@iconpath: '/myicons/';

.icon (@icon) {
    background: no-repeat url('@{iconpath}@{icon}');
}

.icon-foo { .icon('foo.png'); }
.icon-bar { .icon('bar.png'); }
.icon-spuds { .icon('spuds.png'); }

This code compiles to (using )

.icon-foo {
  background: no-repeat url('/myicons/foo.png');
}
.icon-bar {
  background: no-repeat url('/myicons/bar.png');
}
.icon-spuds {
  background: no-repeat url('/myicons/spuds.png');
}

Answer №4

Check out this refined method for managing image paths in LESS:

Begin by setting your variable:

@imagePath: ~"../resources/images/";

Then apply it like so:

.header-img { 
   background: url('@{imagePath}header-image.jpg') repeat scroll left top; 
}

Ensure that the @imagePath points to the images directory relative to where your CSS is compiled, not where the LESS files are located. It's also important to escape the address within the variable to prevent rewriting by less.js, as shown in the example above.

Answer №5

Anton Strogonoff's insightful response can be found here. However, it is crucial to take into consideration the potential Issue @294:

When using the code snippet provided in the documentation, you may encounter a situation where the URL path does not behave as expected. For instance, this setup functions correctly:

@base-url: "../../images/";
@background-image : url ("@{base-url}/bg.png");

On the other hand, the following configuration does not yield the desired outcome:

$base-url: "http://localhost/ns/assets/images/";
@background-image : url ("@{base-url}/bg.png";

The result of the latter example would lead to an incorrect source path:

http://localhost/ns/assets/css/libs/http://localhost/ns/assets/images/bg.png

Answer №6

Managing relative URLs through the command line compiler seems to be a viable option. It is likely that a similar setting can be configured in the file watcher as well.

UPDATE: A solution does exist. Check it out here: 

relativeUrls: true
