The **`manifest`** attribute of the `<html>` element specifies a URL of an application cache manifest that is downloaded in the early stages of page load.

> **Note:** manifest-based caching mechanism has been deprecated. Use service workers instead.

The manifest attribute has only effect during early stages of page load, thus changing it via regular DOM interfaces has no effect, {{domxref("Window.applicationCache")}} interface instead.
