Mastering SASS/CSS, how to set backgrond image?

[josser]

Hi, I'm trying to add custom css to my project.
app.json:

"css": [{
            "path": "resources/css/app.css",
            "update": "delta"
          }, {
          "path": "resources/css/styles.css",
          "update": "delta"
          }
    ],

resources/sass/styles.saas

.c-post-marker {
    position: relative;
    background-image: image-url('resources/images/post_marker.png');
    height: 61px;
    width: 50px;
}

sencha app build package:

[shellscript] WARNING: '''post_marker.png''' was not found (or cannot be read) in /Users/josser/Projects/project_name/resources/sass/Users/josser/Projects/project_name/resources/sass/../images/resources/images

So, for some reason path is realy wrong because it doubled.
I tried to set absolute path:

background-image: image-url('/resources/images/post_marker.png');

but no luck, image just didn't load. I checked what it tries to load in weinre and found this:

file:///resources/images/post_marker.png

So, what is correct way to set path for images?
Thanks!

a proper SASS file doesn't have extension .sass and the build process for Sencha Command shouldn't be compiling your SASS (the new Cmd does) so are you including post_marker.png somewhere else in app.json?

Oh, I'm very sorry, the correct filename is styles.scss instead of styles.saas
