CSS guidelines

Goals

• Maintainable OOCSS components
• Scalable code

Naming

• BEM - Block-element--modifier
• PascaleCase for component name
• camelCase for component childs
• Lowercase for modifiers
• Use is-* and has-* modifiers when needed

<div class="Component Component--modifier is-state">
  <div class="Component-child"></div>
  <div class="Component-otherChild"></div>
</div>

Spacing and indentation

• Two spaces indent
• Space after : property declaration
• Space before { rule declaration
• Closing braces on a new line

.Component {
  display: inline-block;
}

Else

• Never use IDs
• No magic number
• Only use !important on utility classes
• Max nesting level: 3

Development

Installation

npm install
npm install -g gulp pug-cli backstopjs

Run

gulp // starts server and watch files, available on localhost:3000
gulp icons // builds icons

Pre-commit and pre-push

Installation

Pre-commit hook ensures code has been linted.

npm run pre-commit

Bypass

To bypass the pre-commit, just add -n option.

git ci -n
git ci -nm "My commit message"

Release

npm run release // builds, commits, push, tags, publishes to Bower and NPM and deploys to GitHub Pages

Deploying

It can be run manually:

npm run deploy

Tests

Tests are run with Travis and have to be updated before branch merges. They can be run locally with these following commands.

npm run lint // linter
backstop reference // visual tests: builds references
backstop test // visual tests: compares references with actual HEAD
