| Do | Put secondary actions like "Back" on the left, and primary actions like "Save" on the right. |
| Do | Make temporary toolbars like bulk selection visually distinct so users can tell they're contextual, for example with a background color or border. |
| Do | Visually separate the toolbar from the content below it, with a divider, a background variant, or both. |
| Do | Use Toolbar as a card header when the header has interactive actions like filter or add; it gives you slot layout, keyboard navigation, and size cascading. If the header is just a title with no actions, a LayoutHeader or Section is enough. |
| Don't | Put too many actions in one toolbar; move less common items into a MoreMenu. |
| Don't | Set size on individual child buttons; set it once on the toolbar and it cascades automatically. |
| Don't | Use Toolbar for app-wide navigation like main menu links or sign out; use TopNav or LayoutHeader for that. |
