| 32 ### Styling | |
| 33 | |
| 34 The following custom properties and mixins are available for styling: | |
| 35 | |
| 36 Custom property | Description | Default | |
| 37 ----------------|-------------|---------- | |
| 38 `--paper-menu-background-color` | Menu background color
| `--primary-background-color` | |
| 39 `-paper-menu-color` | Menu foreground color
| `--primary-text-color` | |
| 40 `--paper-menu-disabled-color` | Foreground color for a disabled item
| `--disabled-text-color` | |
| 41 `--paper-menu` | Mixin applied to the menu
| `{}` | |
| 42 `--paper-menu-selected-item` | Mixin applied to the selected item
| `{}` | |

| 46 ### Accessibility | |
| 47 | |
| 48 `<paper-menu>` has `role="menu"` by default. A multi-select menu will also have | |
| 49 `aria-multiselectable` set. It implements key bindings to navigate through the m
enu with the up and | |
| 50 down arrow keys, esc to exit the menu, and enter to activate a menu item. Typing
the first letter | |
| 51 of a menu item will also focus it. | |
