This is a simplified version of the Code Styleguide used at Seven West Media where we use Glamorous for styles on https://thewest.com.au and http://www.perthnow.com.au
All styled items should have a separate file in the componets folder named according to the component name e.g. heading.styled.tsx
Sub-components should exist in a separate folder with the components folder called component
If there is more than one component, components should be put into their own files
