## Getting Started
You can either download a copy of the [source files](https://github.com/chrishumboldt/Rocket-Propel/archive/master.zip) or install via NPM.
```
npm install rocket-propel
```
## SASS Implementation
Start by importing the necessary file into your own SASS file and include the required mixins.
**SASS**
```scss
@import "rocket-propel/build/sass/import";
.example {
@include row();
.left, .middle, .right {
@include span(12); // 100% width
}
@include breakpoint($bpLarge) {
.left {
@include span-new(6); // 50% width
}
.middle {
@include span-new(4); // 33.33% width
}
.right {
@include span-new(2); // 16.66% width
}
}
}
```
**HTML**
```html
```
#### Browser Prefixes
Propel will apply all the necessary browser prefixes where needed but no longer supports the **-o-** prefix for older versions of Opera. Opera now uses the Blink engine from Chromium (Read More).

## CSS Implementation
Start by including the necessary files.
```html
```
Alternatively you can also build the SASS out if you wish to include all your CSS in one production file. See an example below.
```scss
@import "rocket-propel/build/sass/import";
@include rocket-propel-css;
```
Now class your HTML to manage your layout. For example:
```html
Span 2
Span 2
Span 2
Span 2
Span 2
Span 2
```
#### Classes as Modifiers
Because all classes are declared on the DOM elements themselves, Propel sees them as global modifiers and such uses the `_` prefix to reflect this. In the case of modules the module name would prefix the modifier but that only happens with extensions to Rocket Propel.
