<!--{

Files referenced with the `@import` directive are inlined directly to save on http requests. Relative URL paths in the CSS are also updated if necessary.
If you specify a media designation following the import URL — as per the CSS standard — the imported file content is wrapped in a `@media` block.
```crush
/* Standard CSS @import statements */
@import "print.css" print;
@import url( "small-screen.css" ) screen and ( max-width: 500px );

<!--{
"title": "Rule inheritance"
}-->
By using the `@extend` directive and passing it a named ruleset or selector from any other rule you can share styles more effectively across a stylesheet.
[Abstract rules](#core--abstract) can be used if you just need to extend a generic set of declarations.
```crush
.negative-text {
overflow: hidden;
text-indent: -9999px;
}
.sidebar-headline {
@extend .negative-text;
background: url( headline.png ) no-repeat;
}
```
```css
.negative-text,
.sidebar-headline {
overflow: hidden;
text-indent: -9999px;
}
.sidebar-headline {
background: url( headline.png ) no-repeat;
}
```
Inheritance is recursive:
```crush
.one { color: pink; }
.two { @extend .one; }
.three { @extend .two; }
.four { @extend .three; }
```
```css
.one, .two, .three, .four { color: pink; }
```
## Referencing by name
If you want to reference a rule without being concerned about later changes to the identifying selector use the `@name` directive:
```crush
.foo123 {
@name foo;
text-decoration: underline;
}
.bar {
@include foo;
}
.baz {
@extend foo;
}
```
## Extending with pseudo classes/elements
`@extend` arguments can adopt pseudo classes/elements by appending an exclamation mark:
```crush
.link-base {
color: #bada55;
text-decoration: underline;
}
.link-base:hover,
.link-base:focus {
text-decoration: none;
}
.link-footer {
@extend .link-base, .link-base:hover!, .link-base:focus!;
color: blue;
}
```
```css
.link-base,
.link-footer {
color: #bada55;
text-decoration: underline;
}
.link-base:hover,
.link-base:focus,
.link-footer:hover,
.link-footer:focus {
text-decoration: none;
}
.link-footer {
color: blue;
}
```
The same outcome can also be achieved with an [Abstract rule](#core--abstract) wrapper to simplify repeated use:
```crush
.link-base {
color: #bada55;
text-decoration: underline;
}
.link-base:hover,
.link-base:focus {
text-decoration: none;
}
@abstract link-base {
@extend .link-base, .link-base:hover!, .link-base:focus!;
}
.link-footer {
@extend link-base;
color: blue;
}
```

<!--{
"title": "Mixins"
}-->
Mixins make reusing small snippets of CSS much simpler. You define them with the `@mixin` directive.
Positional arguments via the argument function `#()` extend the capability of mixins for repurposing in different contexts.
```crush
@mixin display-font {
font-family: "Arial Black", sans-serif;
font-size: #(0);
letter-spacing: #(1);
}
/* Another mixin with default arguments */
@mixin blue-theme {
color: #(0 navy);
background-image: url("images/#(1 cross-hatch).png");
}
/* Applying the mixins */
.foo {
@include display-font(100%, .1em), blue-theme;
}
```
```css
.foo {
font-family: "Arial Black", sans-serif;
font-size: 100%;
letter-spacing: .1em;
color: navy;
background-image: url("images/cross-hatch.png");
}
```
## Skipping arguments
Mixin arguments can be skipped by using the **default** keyword:
```crush
@mixin display-font {
font-size: #(0 100%);
letter-spacing: #(1);
}
/* Applying the mixin skipping the first argument so the
default value is used instead */
#foo {
@include display-font(default, .3em);
}
```
Sometimes you may need to use the same positional argument more than once. In this case the default value only needs to be specified once:
```crush
@mixin square {
width: #(0 10px);
height: #(0);
}
.foo {
@include square;
}
```
```css
#foo {
width: 10px;
height: 10px;
}
```
## Mixing-in from other sources
Normal rules and [abstract rules](#core--abstract) can also be used as static mixins without arguments:
```crush
@abstract negative-text {
text-indent: -9999px;
overflow: hidden;
}
#main-content .theme-border {
border: 1px solid maroon;
}
.foo {
@include negative-text, #main-content .theme-border;
}
```

<!--{
"title": "Selector aliases"
}-->
Selector aliases can be useful for grouping together common selector chains for reuse.
They're defined with the `@selector` directive, and can be used anywhere you might use a pseudo class.
```crush
@selector heading :any(h1, h2, h3, h4, h5, h6);
@selector radio input[type="radio"];
@selector hocus :any(:hover, :focus);
/* Selector aliases with arguments */
@selector class-prefix :any([class^="#(0)"], [class*=" #(0)"]);
@selector col :class-prefix(-col);
.sidebar :heading {
color: honeydew;
}
:radio {
margin-right: 4px;
}
:col {
float: left;
}
p a:hocus {
text-decoration: none;
}
```
```css
.sidebar h1, .sidebar h2,
.sidebar h3, .sidebar h4,
.sidebar h5, .sidebar h6 {
color: honeydew;
}
input[type="radio"] {
margin-right: 4px;
}
[class^="col-"],
[class*=" col-"] {
border: 1px solid rgba(0,0,0,.5);
}
p a:hover,
p a:focus {
text-decoration: none;
}
```
## Selector splatting
Selector splats are a special kind of selector alias that expand using passed arguments.
```crush
@selector-splat input input[type="#(text)"];
form :input(time, text, url, email, number) {
border: 1px solid;

Selector grouping with the `:any` pseudo class (modelled after CSS4 :matches) simplifies the creation of complex selector chains.
```crush
:any( .sidebar, .block ) a:any( :hover, :focus ) {
color: lemonchiffon;
}
```
```css
.block a:hover,
.block a:focus,
.sidebar a:hover,
.sidebar a:focus {

<!--{

Declare variables in your CSS with a `@set` directive and use them with the `$()` function.
Variables can also be injected at runtime with the [vars option](#api--options).
```crush
/* Defining variables */
@set {
dark: #333;
light: #F4F2E2;
smaller-screen: screen and (max-width: 800px);
}
/* Using variables */
@media $(smaller-screen) {
ul, p {
color: $(dark);
/* Using a fallback value with an undefined variable */
background-color: $(accent-color, #ff0);
}
}
```
*******
```css
/* Interpolation */
.username::before {
content: "$(greeting)";
}
```
## Conditionals
Sections of CSS can be included and excluded on the basis of variable existence with the `@ifset` directive:
```crush
@set foo #f00;
@set bar true;
@ifset foo {
p {
color: $(foo);
}
}
p {
font-size: 12px;
@ifset not foo {
line-height: 1.5;
}
@ifset bar(true) {
margin-bottom: 5px;
}
}

This preprocessor is written in PHP, so as prerequisite you will need to have PHP installed on your system to use the JS api.
```shell
npm install csscrush
```
All methods can take the standard options (camelCase) as the second argument.
```php
const csscrush = require('csscrush');
// Compile. Returns promise.
csscrush.file('./styles.css', {sourceMap: true});
// Compile string of CSS. Returns promise.
csscrush.string('* {box-sizing: border-box;}');
// Compile and watch file. Returns event emitter (triggers 'data' on compile).
csscrush.watch('./styles.css');

Functions for creating SVG gradients with a CSS gradient like syntax.
Primarily useful for supporting Internet Explorer 9.
## svg-linear-gradent()
Syntax is the same as [linear-gradient()](http://dev.w3.org/csswg/css3-images/#linear-gradient)
```syntax
svg-linear-gradent( [ <angle> | to <side-or-corner> ,]? <color-stop> [, <color-stop>]+ )
```
### Returns
A base64 encoded svg data-uri.
### Known issues
Color stops can only take percentage value offsets.
```css
background-image: svg-linear-gradient( to top left, #fff, rgba(255,255,255,0) 80% );
background-image: svg-linear-gradient( 35deg, red, gold 20%, powderblue );
```
## svg-radial-gradent()
Syntax is similar to but more limited than [radial-gradient()](http://dev.w3.org/csswg/css3-images/#radial-gradient)
```syntax
svg-radial-gradent( [ <origin> | at <position> ,]? <color-stop> [, <color-stop>]+ )
```
### Returns
A base64 encoded svg data-uri.
### Known issues
Color stops can only take percentage value offsets.
No control over shape - only circular gradients - however, the generated image can be stretched with background-size.
```css
background-image: svg-radial-gradient( at center, red, blue 50%, yellow );
background-image: svg-radial-gradient( 100% 50%, rgba(255,255,255,.5), rgba(255,255,255,0) );

drop-shadow: 2 2 0 rgba(0,0,0,1);
}

```crush
/* 8-sided polygon with an image fill.
Note: images usually have to be converted to data URIs, see known issues below. */
@svg pattern {
type: polygon;
sides: 8;
diameter: 180;
margin: 20;
fill: pattern(data-uri(kitten.jpg), scale(1) translate(-100 0));
fill-opacity: .8;
}
```
### Known issues
Firefox [does not allow linked images](https://bugzilla.mozilla.org/show_bug.cgi?id=628747#c0) (or other svg) when svg is in "svg as image" mode.
