CSS Zero

An opinionated CSS starter kit for your Ruby on Rails application. You can think of it like a "no build" Tailwind CSS.

Add this gem to your project.

bundle add css-zero

Run the install command.

bin/rails generate css_zero:install

Add the additional components you need. (Optional)

bin/rails generate css_zero:add --help

<h1 class="text-xl font-bold mb-4">
  Write most page content using utility classes.
</h1>

<div class="custom-component">
  Create components using CSS variables.
</div>

<div class="card">
  Optionally, copy pre-built components into your application.
</div>

.custom-component {
  background-color: var(--red-500);
  border-radius: var(--rounded);
  block-size: var(--size-4);
}

Check the CSS files in the repository to see the available variables and utility classes.

Some icons in the examples are not copied to the project. If you are looking for good ones, I recommend Lucide.

This gem implements custom templates for scaffolds and authentication.

To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
