MDN will switch to a new design later today, a sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

Secure context
This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The Coordinates.altitudeAccuracy read-only property is a strictly positive double representing the accuracy, with a 95% confidence level, of the altitude expressed in meters. This value is null if the implementation doesn't support measuring altitude.

Syntax

altAcc = coordinates.altitudeAccuracy
