# ViewComponentScopedCss
Provides per-component scoped scss for viewcomponent

By providing special prefixes as scss class names, you can describe closed styles for each component, so you don't have to worry about css design such as bem.


## Installation

Add this line to your application's Gemfile:

```ruby
gem 'view_component_scoped_css'
```

And then execute:

    $ bundle install

Or install it yourself as:
