Nadarei KSS

Nadarei KSS Styleguides lets you create pretty styleguides for your Rails 3.2 projects.


What is KSS?

It's a standard for documenting stylesheets. It's also a tool that parses these sheets, which nkss-rails uses.

See the KSS website at

What is nkss-rails?

A drop-in, easy-to-use, gorgeous-by-default Rails plugin you can put into your projects so you can instantly have cute docs.

It's a pre-configured distribution of KSS. I've already done the grunt work for you, like setting up the layouts, templates and CSS files for your styleguide. All you gotta worry about is documenting your styles!


Add me, and haml, to your Gemfile.

gem 'haml'
gem 'nkss-rails', github: 'nadarei/nkss-rails'

Then type bundle to update your bundle. Then, install the needed files into your project:

$ bundle exec rails generate nkss:install

Now move on to the next section.


This gives you the following things that you should customize:


A list of sections in your styleguide. Your mission: edit this file to add your own sections.


Your styleguides live here. Your mission: edit the first styleguide (1.html.haml) and later, add your own.


The layout for your styleguide. Your mission: make sure that this loads the right styles and scripts that your application uses.


Place any extra CSS definitions in here.

Viewing your sheets

Now visit http://localhost:8000/styleguides. It should work straight away. By default, it's only enabled in development mode.

This works because you have a new route added to your app that mounts the Nkss engine to that path:

Rails.application.routes.draw do
  mount Nkss::Engine => '/styleguides'  if Rails.env.development?

How to document your styles

When you do the process above, you should already have an example in app/assets/stylesheets/example-for-styleguides.css. But here's how to do it, anyway...

Document your CSS

In your CSS file, add a KSS document block. In this example, we'll define section 1.3. Refer to the KSS Syntax page for more info.

A button for doing things.

Styleguide 1.3.
.button {
  color: red

Add the markup

Add the markup in the corresponding section in app/views/styleguides/N.html.haml, where N is the main section number. In this case, we'll be editing 1.html.haml.

-# 1.html.haml
= kss_block '1.3' do
  %a.button{href: '#'} Do things

For new main sections

If you're adding a new main section, edit the file config/styleguides.yml to add it to the menu.

# config/styleguides.yml
title: My Site
  1: Buttons
  2: Forms
  3: Ratings
  4: ...

That's it!

You should see your newly-documented style in http://localhost:8000/styleguides/1.

Using in production

Just make sure to add styleguide.css and styleguide-extras.css to your precompilation list. Usually this is in config/environments/production.rb.

Our bias

We use this happily with our client projects, and our clients are happy with it, too. It has quite a bias with our process (for instance: HAML by default), sorry about that.

Our primary purpose of maintaining this package is to use it for our projects; as such, we can't always guarantee that all contributions will be merged in.

If you feel this is too limiting, you can always override the templates or CSS by copying them to your application.

Alternatively, simply copy the entire gem to your project and hack away at it yourself:

$ git clone ./vendor/nkss-rails

# In your gemfile:
gem 'nkss-rails', path: 'vendor/nkss-rails'
