Web/HTML/Element/iframe

The HTML Inline Frame element (<iframe>) represents a nested browsing context, embedding another HTML page into the current one.

The source for this interactive example is stored in a GitHub repository. If you'd like to contribute to the interactive examples project, please clone https://github.com/mdn/interactive-examples and send us a pull request.

Each embedded browsing context has its own session history and document. The browsing context that embeds the others is called the parent browsing context. The topmost browsing context — the one with no parent — is usually the browser window, represented by the Window object.

Because each browsing context is a complete document environment, every <iframe> in a page requires increased memory and other computing resources. While theoretically you can use as many <iframe>s as you like, check for performance problems.

Content categories	Flow content, phrasing content, embedded content, interactive content, palpable content.

Tag omission	None, both the starting and ending tag are mandatory.
Permitted parents	Any element that accepts embedded content.
Implicit ARIA role	No corresponding role
Permitted ARIA roles	application, document, img, none, presentation
DOM interface	HTMLIFrameElement

Attributes

This element includes the global attributes.

allow

Specifies a feature policy for the <iframe>. The policy defines what features are available to the <iframe> based on the origin of the request (e.g. access to the microphone, camera, battery, web-share API, etc.). For more information and examples see: Using Feature Policy > The iframe allow attribute.

allowfullscreen

Set to true if the <iframe> can activate fullscreen mode by calling the requestFullscreen() method.

This attribute is considered a legacy attribute and redefined as allow="fullscreen".

allowpaymentrequest

Set to true if a cross-origin <iframe> should be allowed to invoke the Payment Request API.

This attribute is considered a legacy attribute and redefined as allow="payment".

csp '

A Content Security Policy enforced for the embedded resource. See HTMLIFrameElement.csp for details.

height

The height of the frame in CSS pixels. Default is 150.

loading '

Indicates how the browser should load the iframe:

• eager: Load the iframe immediately, regardless if it is outside the visible viewport (this is the default value).
• lazy: Defer loading of the iframe until it reaches a calculated distance from the viewport, as defined by the browser.

name

A targetable name for the embedded browsing context. This can be used in the target attribute of the <a>, <form>, or <base> elements; the formtarget attribute of the <input> or <button> elements; or the windowName parameter in the window.open() method.

referrerpolicy

Indicates which referrer to send when fetching the frame's resource:

• no-referrer: The Referer header will not be sent.
• no-referrer-when-downgrade (default): The Referer header will not be sent to origins without TLS (HTTPS).
• origin: The sent referrer will be limited to the origin of the referring page: its scheme, host, and port.
• origin-when-cross-origin: The referrer sent to other origins will be limited to the scheme, the host, and the port. Navigations on the same origin will still include the path.
• same-origin: A referrer will be sent for same origin, but cross-origin requests will contain no referrer information.
• strict-origin: Only send the origin of the document as the referrer when the protocol security level stays the same (HTTPS→HTTPS), but don't send it to a less secure destination (HTTPS→HTTP).
• strict-origin-when-cross-origin: Send a full URL when performing a same-origin request, only send the origin when the protocol security level stays the same (HTTPS→HTTPS), and send no header to a less secure destination (HTTPS→HTTP).
• unsafe-url: The referrer will include the origin and the path (but not the fragment, password, or username). This value is unsafe, because it leaks origins and paths from TLS-protected resources to insecure origins.

sandbox

Applies extra restrictions to the content in the frame. The value of the attribute can either be empty to apply all restrictions, or space-separated tokens to lift particular restrictions:

• allow-downloads-without-user-activation ' : Allows for downloads to occur without a gesture from the user.
• allow-downloads: Allows for downloads to occur with a gesture from the user.
• allow-forms: Allows the resource to submit forms. If this keyword is not used, form submission is blocked.
• allow-modals: Lets the resource open modal windows.
• allow-orientation-lock: Lets the resource lock the screen orientation.
• allow-pointer-lock: Lets the resource use the Pointer Lock API.
• allow-popups: Allows popups (such as window.open(), target="_blank", or showModalDialog()). If this keyword is not used, the popup will silently fail to open.
• allow-popups-to-escape-sandbox: Lets the sandboxed document open new windows without those windows inheriting the sandboxing. For example, this can safely sandbox an advertisement without forcing the same restrictions upon the page the ad links to.
• allow-presentation: Lets the resource start a presentation session.
• allow-same-origin: If this token is not used, the resource is treated as being from a special origin that always fails the same-origin policy.
• allow-scripts: Lets the resource run scripts (but not create popup windows).
• allow-storage-access-by-user-activation ' : Lets the resource request access to the parent's storage capabilities with the Storage Access API.
• allow-top-navigation: Lets the resource navigate the top-level browsing context (the one named _top).
• allow-top-navigation-by-user-activation: Lets the resource navigate the top-level browsing context, but only if initiated by a user gesture.

Notes about sandboxing:

• When the embedded document has the same origin as the embedding page, it is strongly discouraged to use both allow-scripts and allow-same-origin, as that lets the embedded document remove the sandbox attribute — making it no more secure than not using the sandbox attribute at all.
• Sandboxing is useless if the attacker can display content outside a sandboxed iframe — such as if the viewer opens the frame in a new tab. Such content should be also served from a separate origin to limit potential damage.
• The sandbox attribute is unsupported in Internet Explorer 9 and earlier.

src

The URL of the page to embed. Use a value of about:blank to embed an empty page that conforms to the same-origin policy. Also note that programatically 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.

srcdoc

Inline HTML to embed, overriding the src attribute. If a browser does not support the srcdoc attribute, it will fall back to the URL in the src attribute.

width

The width of the frame in CSS pixels. Default is 300.

Deprecated attributes

These attributes are deprecated and may no longer be supported by all user agents. You should not use them in new content, and try to remove them from existing content.

align '

The alignment of this element with respect to the surrounding context.

frameborder '

The value 1 (the default) draws a border around this frame. The value 0 removes the border around this frame, but you should instead use the CSS property border to control <iframe> borders.

longdesc '

A URL of a long description of the frame's content. Due to widespread misuse, this is not helpful for non-visual browsers.

marginheight '

The amount of space in pixels between the frame's content and its top and bottom borders.

marginwidth '

The amount of space in pixels between the frame's content and its left and right borders.

scrolling '

Indicates when the browser should provide a scrollbar for the frame:

auto

• Only when the frame's content is larger than its dimensions.
• yes: Always show a scrollbar.
• no: Never show a scrollbar.

Non-standard attributes

mozbrowser '

See bug 1318532 for exposing this to WebExtensions in Firefox.

Makes the <iframe> act like a top-level browser window. See Browser API for details.

Available only to WebExtensions.

Scripting

Inline frames, like <frame> elements, are included in the window.frames pseudo-array.

With the DOM HTMLIFrameElement object, scripts can access the window object of the framed resource via the contentWindow property. The contentDocument property refers to the document inside the <iframe>, same as contentWindow.document.

From the inside of a frame, a script can get a reference to its parent window with window.parent.

Script access to a frame's content is subject to the same-origin policy. Scripts cannot access most properties in other window objects if the script was loaded from a different origin, including scripts inside a frame accessing the frame's parent. Cross-origin communication can be achieved using Window.postMessage().

Positioning and scaling

As a replaced element, the position, alignment, and scaling of the embedded document within the <iframe> element's box, can be adjusted with the object-position and object-fit properties.

Examples

A simple <iframe>

An <iframe> in action. After creating the frame, when the user clicks a button, its title is displayed in an alert.

HTML

<iframe src="https://mdn-samples.mozilla.org/snippets/html/iframe-simple-contents.html"
            title="iframe Example 1" width="400" height="300">
</iframe>

Accessibility concerns

People navigating with assistive technology such as a screen reader can use the title attribute on an <iframe> to label its content. The title's value should concisely describe the embedded content:

<iframe title="Wikipedia page for Avocados" src="https://en.wikipedia.org/wiki/Avocado"></iframe>

Without this title, they have to navigate into the <iframe> to determine what its embedded content is. This context shift can be confusing and time-consuming, especially for pages with multiple <iframe>s and/or if embeds contain interactive content like video or audio.
