# Bitters [](https://rubygems.org/gems/bitters) *** ## Scaffold styles, variables and structure for [Bourbon](http://bourbon.io) projects. Bitters helps designers start projects faster by defining a basic set of Sass variables, default element style and project structure. It’s been specifically designed for use within web applications. Bitters should live in your project’s root Sass directory and we *encourage* you to modify and extend it to meet your design and brand requirements. Bitters is made to work alongside a CSS reset and not replace it. Our suggested reset is [Normalize](http://necolas.github.io/normalize.css). ## Requirements - [Sass](https://github.com/sass/sass) 3.0+ - [Bourbon](https://github.com/thoughtbot/bourbon) 2.0+ - Ruby 1.9.3+ (required to install Bitters from the command line) ## Installation Bitters uses the [RubyGems](https://rubygems.org) package manager to easily generate a `base` directory with all of the necessary files. For command line help, use `bitters help` or visit the [Command Line Interface Wiki](https://github.com/thoughtbot/bitters/wiki/Command-Line-Interface). 1. Install the Bitters gem: ```bash gem install bitters ``` *If you use [rbenv](https://github.com/sstephenson/rbenv), be sure to run `rbenv rehash` without any errors.* 2. Install [Bourbon](https://github.com/thoughtbot/bourbon#installation) (required) and [Neat](https://github.com/thoughtbot/neat#installation) (optional). 3. Install the Bitters library into the current directory: ```bash bitters install ``` A `base` directory will be generated which contains all of the Bitters files. 4. Import Bitters after Bourbon in your `application.css.scss` or main manifest file. All additional stylesheets should be imported below Bitters. ```bash @import "bourbon"; @import "base/base"; ``` 5. When using Neat, uncomment the following line in `_base.scss`: ```scss @import "grid-settings"; ``` And import Neat after Bitters: ```scss @import "bourbon"; @import "base/base"; @import "neat"; // All other imports ``` If you want to use Neat functions in Bitters, you can `@import "grid-settings";` before Neat, remove `@import "grid-settings";` from `_base.scss` and import the rest of bitters after. For example: ```scss @import "bourbon"; @import "base/grid-settings"; @import "neat"; @import "base/base"; // All other imports ``` ## Using Bitters ### Sass structure & default style The Bitters directory should contain styles for all the basic elements used throughout the project. It also contains directories for custom mixins and extends for your site as well. Add code to the existing files or add new files to the directories. Customize Bitters for your site as you see fit. ### Variables This houses all variables that are used, or will be used, in more than one file in your site. Variable names in Bitters that are used outside of the variables file start with `$base` to indicate that they are the most basic variables. ### Grid settings Variables specifically created for [Neat](http://neat.bourbon.io) resets and breakpoints. To be used, these need to be imported separately from the rest of your base file above Neat in your main stylesheet. Otherwise just remove the file. ### Typography All type is based on `$base-font-size` which is set to 1em (16px) by default. The spacing around type is based on `$base-line-height` so as to keep a semi-baseline grid. All sizes are scaled up or down by a factor of `.25`. ### Lists All lists have stripped out styles. No bullets, no left padding. To add back the expected browser default styles add `@extend %default-ul;` or `@extend %default-ol;` to the `
