The HTMLIFrameElement interface provides special properties and methods (beyond those of the HTMLElement interface it also has available to it by inheritance) for manipulating the layout and presentation of inline frame elements.

EventTarget Node Element HTMLElement HTMLIFrameElement


Inherits properties from its parent, HTMLElement.


A string that specifies the alignment of the frame with respect to the surrounding context.


A list of origins the frame is allowed to display content from. This attribute also accepts the values self and src which represent the origin in the iframe's src attribute. The default value is src.


A boolean value indicating whether the inline frame is willing to be placed into full screen mode. See Using full-screen mode for details.


A boolean value indicating whether the Payment Request API may be invoked inside a cross-origin iframe.

HTMLIFrameElement.contentDocument Read only

Returns a Document, the active document in the inline frame's nested browsing context.

HTMLIFrameElement.contentWindow Read only

Returns a WindowProxy, the window proxy for the nested browsing context.


Specifies the Content Security Policy that an embedded document must agree to enforce upon itself.


A string that indicates whether to create borders between frames.


A string that reflects the height HTML attribute, indicating the height of the frame.

A string that reflects the referrerpolicy HTML attribute indicating which referrer to use when fetching the linked resource.


A DOMTokenList that reflects the sandbox HTML attribute, indicating extra restrictions on the behavior of the nested content.


A string that indicates whether the browser should provide scrollbars for the frame.


A string that reflects the src HTML attribute, containing the address of the content to be embedded. Note that programmatically removing an <iframe>'s src attribute (e.g. via Element.removeAttribute()) causes about:blank to be loaded in the frame in Firefox (from version 65), Chromium-based browsers, and Safari/iOS.


A string that represents the content to display in the frame.
