@import with Sass not combining files

Question

I'm new to sass and I'm trying to import a parent theme's css in a Magento application.

I have it working to an extent but not with the result I was expecting.

In my styles.scss folder I have:

@import "../../../rwd/default/css/styles.css";

I have run the sass --watch styles.scss:styles.css in the terminal and the resulting styles.css file has:

@import url(../../../rwd/default/css/styles.css);

In the sass guide it says:

CSS has an import option that lets you split your CSS into smaller, more maintainable portions. The only drawback is that each time you use @import in CSS it creates another HTTP request. Sass builds on top of the current CSS @import but instead of requiring an HTTP request, Sass will take the file that you want to import and combine it with the file you're importing into so you can serve a single CSS file to the web browser.

So I was expecting SASS to import the css as plain old css rules rather than using the @import rule, so my styles.css would look something like:

/* ==========================================================================
   HTML5 display definitions
   ========================================================================== */
/*
 * Corrects `block` display not defined in IE 8/9.
 */
article,

  display: block;
}

audio,

  display: inline-block;
}

/*

audio:not([controls]) {

[hidden] {
  display: none;

 */
mark {
  background: #ff0;
  color: #000;
}

/*
 * Corrects font family set oddly in Safari 5 and Chrome.
 */
code,
kbd,
pre,
samp {
  font-family: monospace, serif;
  font-size: 1em;
}

/*
 * Improves readability of pre-formatted text in all browsers.
 */
pre {
  white-space: pre;
  white-space: pre-wrap;
  word-wrap: break-word;
}

/*
 * Sets consistent quote types.
 */
q {
  quotes: "\201C" "\201D" "\2018" "\2019";
}

/*
 * Addresses inconsistent and variable font size in all browsers.
 */
small {
  font-size: 80%;
}

/*
 * Prevents `sub` and `sup` affecting `line-height` in all browsers.
 */
sub,
sup {
  font-size: 75%;
  line-height: 0;
  position: relative;
  vertical-align: baseline;
}

That way I would have a styles.css on production which didn't use the @import rule.

Answer 1

I got it to work by following this article:

http://sass-lang.com/documentation/file.SASS_REFERENCE.html#import

@import by default looks for a Sass file to import directly, but if the is a .css file or if the filename is a url it will compile to a CSS @import rule. Both of which were the case for me.

So my solution was to copy the css file I wanted to import & rename it rwd_styles.scss & changed my scss import rule to @import "rwd_styles.scss"; and it worked as I had hoped.
