Top App Bar

Top App Bar acts as a container for items such as application title, navigation icon, and action items.

• Module @pmwcs/top-app-bar
• Import styles:
  • Using CSS Loader
    • import '@pmwcs/top-app-bar/styles';
  • Or include stylesheets
    • '@material/top-app-bar/dist/mdc.top-app-bar.css'
    • '@material/icon-button/dist/mdc.icon-button.css'
    • '@material/ripple/dist/mdc.ripple.css'
    • '@pmwcs/icon/icon.css'
• MDC Docs: https://material.io/develop/web/components/top-app-bar/

Whats the difference between the TopAppBar and Toolbar? Toolbar is technically deprecated (although it still works just fine). TopAppBar functionality continues to be worked on by the material-components-web team.
