SuttaCentral
According to Material Design Specs and Polymer Paper Styles.
Work in progress
Navbar: --shadow-elevation-16dp
Toolbar: --shadow-elevation-8dp
Dropdown menus: standard from paper-dropdown
Suttaplex card: standard from paper-card
Suttaplex card selected: --shadow-elevation-8dp
details summary popup: --shadow-elevation-3dp
@Sujato: I have used these elevations based on the specs. I noticed you had used the toolbar at 6dp instead.
Okay, use whatever the guidelines say. The overall depth can change depending on the amount of layers also. But anyway, just go with the standard and see if it works.
I’m nearly done with the suttaplex … have you installed git?
