main.css

/*
    Based on ITCSS structure (http://tinyurl.com/hgujuha)

    # Layers
    - Settings:     font, colors definitions, etc.
    - Tools:        globally used mixins and functions.
    - Generic:      reset/normalize styles, box-sizing definition, etc.
    - Elements:     styling for bare HTML elements.
    - Objects:      class-based selectors which define undecorated design patterns
    - Components:   specific UI components

    # Notes
    - No CSS should be outputted from the first 2 layers (settings & tools)
