What is an iframe in html


The Applicability section explains the scope of the technique, and the presence of techniques for a specific technology does not imply that the technology can be used in all situations to create content that meets WCAG 2. Note: This technique must be combined with other techniques to meet SC 2. See Understanding SC 2.

The objective of this technique is to demonstrate the use of the title attribute of the frame or iframe element to describe the contents of each frame.

What is an HTML Iframe tag?

This provides a label for the frame so users can determine which frame to enter and explore in detail.

It does not label the individual page frame or inline frame iframe in the frameset. Note that the itol tutorial attribute labels frames, and is different from the title element which labels documents.

Both should be provided, since the first facilitates navigation among frames and the second clarifies the user's current location. The title attribute is not interchangeable with the name attribute. The title labels the frame for users; the name labels it for scripting and window targeting. The name is not presented to the user, only the title is. In HTML5 the frame element is marked as obsolete. The iframe element remains part of the HTML5 specification. This example shows how to use the title attribute with frame to describe the frames containing the navigation bar and the document.

This example shows how to use the title attribute with iframe to describe the contents of an inline frame. The example also includes an alternative link to the page included by the iframe element for older browsers, which may not understand the iframe element. HTML 4.

If this is a sufficient technique for a success criterion, failing this test procedure does not necessarily mean that the success criterion has not been satisfied in some other way, only that this technique has not been successfully implemented and can not be used to claim conformance. The entire document is also available as a single HTML file. W3C liabilitytrademark and document use rules apply.

Not supported in HTML5. Use CSS border property instead. Learn how in the CSS Borders tutorial. It specifies a document link that contains long description for the inline frame. It sets margin values for top and bottom of the content in an inline frame.

If a browser does not support the srcdoc attribute, it will fall back to the URL in the src attribute. 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. The value 1 the default draws a border around this frame. A URL of a long description of the frame's content. Due to widespread misuse, this is not helpful for non-visual browsers.

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

The title's value should concisely describe the embedded content:. Note: When the embedded document has the same origin as the embedding page, it is strongly discouraged to use both allow-scripts and allow-same-originas 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. Privacy, permissions, and information security.Sharing content is a fairly common practice.

Fortunately, iFrames provide a simple solution to these issues. An iFrame is a way to embed a web page into the content of another page.

In most cases, embedding content via an iFrame is not considered to be copyright infringement also see EU ruling. Additionally, the code within an iFrame cannot be directly accessed. The second reason you may want to incorporate iFrames is for sharing large files, such as video, audio, or even images. YouTube is the perfect example here.

This technique will help make you a more ethical member of the online community and keep your site fast and easy to use. Just as there are various scenarios in which you might want to use an iFrame, there are multiple methods for implementing one. The basic code for adding an iFrame to a page is fairly simple. There are a couple of limitations to note regarding the source URL. First, iFrames can only display content from sites that use the same Hypertext Transfer Protocol as yours.

Additionally, some popular websites — such as Facebook and YouTube — disable manual iFrame embedding. A few of the most common ones include:. There are other parameters you may consider using as well. However, the ones listed above should enable you to create basic iFrames for sharing YouTube videos or other content on your site. Some sites have restrictions on whether you can manually embed their content in iFrames.

This can make it difficult to feature certain types of content, such as Facebook posts or YouTube videos. Rather, you simply have to access the necessary embed codes in order to do so. Underneath the video player, you should see a Share button:.The iframe is often used to add content from other sources like an advertisement into a web page.

The solution for the above concern is, we must find the index of the iframe through which the element is being loaded and then we need to switch to the iframe through the index.

Below are the steps for finding the index of the Frame by which the element is being loaded by using below snippet. Step 3. Output: Browser navigates to the page consisting the above iframe and clicks on the iframe. In the case of nested frames. While exiting out of the frame, we must exit out in the same order as we entered into it from the inner frame first and then outer frame.

When loading an iframe, the browser sends it important information about who is loading it in the Referer header notice the single ra typo we must live with. The misspelling of referrer originated in the original proposal by computer scientist Phillip Hallam-Baker to incorporate the field into the HTTP specification. The misspelling was set in stone by the time of its incorporation into the Request for Comments standards document RFC The referrerpolicy attribute lets us set the referrer to send to the iframe when loading it.

The screenshot is taken from an iPhone in portrait mode pixels wideand the rest of the page has been shrunk so that the embedded content fits the screen.

Far from ideal! Screenshot taken from an iPhone in portrait mode px wide. Larger view. Fortunately, there is a way around this using CSS.

A popular plugin is FitVids. A more current solution is to use just a script — such as FluidVids.

It works not only for YouTube, but for Vimeo, too. Apart from videos and calendars, another common issue is the embedding of Google maps, responsively.

Basically, we again use the same intrinsic ratio technique, and when setting padding-bottom for the wrapper, we just divide the height by width and add the aspect ratio in CSS.

We just wrap a div around the iframe and apply the familiar CSS styling to it:. Again, we can just use EmbedResponsively to generate the copy-paste-code with one click.
