HTMLLinkElement: integrity property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The integrity property of the HTMLLinkElement interface is a string containing inline metadata that a browser can use to verify that a fetched resource has been delivered without unexpected manipulation.

It reflects the integrity attribute of the <link> element.
