- Multi purpose can be a html element, attribute, class or all
- For element tags a ':' or '-' in the directive name will search for the camel case i.e.: light-a-fire will look for a directive named lightAFire
- For element tags a ':' or '-' in the directive name will search for the camel case i.e.: ```light-a-fire``` will look for a directive named lightAFire
- Don't use self-closing tag ```<light-a-fire/>``` use ```<light-a-fire></light-a-fire>``` instead
