When to use it
A space that never breaks a line, so the words on either side stay together: 10 km, Mr Smith, 9 am. Browsers also keep a run of them instead of collapsing it into one space, which is why rows of were once used for indentation; CSS margin or padding does that job properly. In most fonts it is exactly as wide as an ordinary space.
The name dates from HTML 4, so it works in every browser and in old email clients.
Browsers also accept the legacy form   without a semicolon, for compatibility with old pages; new HTML should always end the reference with a semicolon.
It has no visible shape of its own, which is why the box above shows it with a tinted background.
