A button that displays a single icon, designed for compact, icon-only interactions such as toolbar actions, floating action buttons, or inline controls.

The icon is sourced from the icon registry via the name and collection attributes. Like the normal button, it can render as an anchor element when href is set and is fully form-associated.
Slots
default — Optional label rendered alongside the icon, useful for accessibility or augmented layouts.
CSS Parts
base — The wrapping element of the icon button.
icon — The icon element of the icon button.

Prompts the browser to download the linked resource rather than navigating to it. The optional value is used as the suggested file name. Only effective when href is set.

rel

Section titled "rel"

The relationship between the current document and the linked URL. Accepts a space-separated list of link types (e.g. 'noopener noreferrer'). Only effective when href is set. When target="_blank" is used, setting rel="noopener noreferrer" is strongly recommended for security.
