Installation

Requires Rails 3.1 and higher.

gem 'grader'

Also you will need Bourbon installed.

Getting Started

At first configure Bourbon as it explained in official github page.

Then import grader after bourbon in application.css.scss. For example:

@import "bourbon";
@import "grader";

By default grader's grid have 12 columns with 60px height per column and 20px gutter. You can override it by creating variables.css.scss and import it to your application.css.scss file.

For example to create 16 columns grid with 30px height per column and 10px gutter:

$gw-column: 30px;
$gw-gutter: 10px;
$gw-count: 16;

Usage

Simple row with 3 columns:

<section class="container">
  <div class="row">
    <div class="span-3">
      Left column.
    </div>
    <div class="span-6">
      Middle column.
    </div>
    <div class="close-3">
      Right column without left padding.
    </div>
  </div>
</secton>

Offsetting columns:

<section class="container">
  <div class="row">
    <div class="span-4">
      Left column.
    </div>
    <div class="span-4 prefix-4">
      Right column with margin from left for 4 columns.
    </div>
  </div>
  <div class="row">
    <div class="span-4 suffix-4">
      Left column with margin from right for 4 columns..
    </div>
    <div class="span-4">
      Right column 
    </div>
  </div>
</secton>

Nesting columns:

<section class="container">
  <div class="row">
    <div class="span-12">
      Level 1 of column
      <div class="row">
        <div class="span-6">Level 2</div>
