Turn off notifications for one app

1. Open System Settings › Notifications.
2. Scroll to Application Notifications and click the app.
3. Turn off Allow notifications. Or keep them but untick Desktop and Lock Screen, so they only collect in Notification Center.

Silence everything for a while

1. Click Control Center in the menu bar, then Focus.
2. Click Do Not Disturb, and choose how long: for an hour, until this evening, or until you turn it off.

To let some people or apps through, set up a Focus in System Settings › Focus.

Hide notifications while presenting

In System Settings › Notifications, find when mirroring or sharing the display under Show Notifications and set it to Notifications Off, which is the default. Notifications stay quiet while you share your screen in a call or mirror to a TV.

Hide what notifications say

In System Settings › Notifications, set Show previews to When Unlocked or Never. Message text and email subjects then stay hidden on the lock screen.

Stop websites asking to send notifications

In Safari, open Settings › Websites › Notifications and untick Allow websites to ask for permission to send notifications. Chrome and Firefox have a similar setting under site permissions.
