When to use it

The em dash, roughly the width of a capital M, sets off a phrase or marks a break in a sentence. Chicago style sets it without spaces and AP style with them; British style often uses a spaced en dash (–) for the same job. It is longer than both the en dash and the hyphen on the keyboard.

The name dates from HTML 4, so it works in every browser and in old email clients.
