Can i iframe

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.

Also, the content inside an iframe exists entirely independent from the surrounding elements. The URL specified in the src attribute points to the location of an external object or a web page.

The height and width attributes are used to specify the height and width of the iframe. The default width of an iframe is pixels, whereas the default height is pixels.

The iframe has a border around it by default. CSP stands for content security policy and provides a set of HTTP Headers metadata sent along with your web pages when they are served from a web server designed to improve the security of your HTML document. This can prevent other websites from embedding your content in their web pages which would enable clickjacking and a host of other attacks , which is exactly what the MDN developers have done, as we saw earlier on.

Obviously, it's rather out of scope for a full explanation in this article. Note: A plugin , in this context, refers to software that provides access to content the browser cannot read natively. However, you are unlikely to use these elements very much — Applets haven't been used for years, Flash is no longer very popular, due to a number of reasons see The case against plugins , below , PDFs tend to be better linked to than embedded, and other content such as images and video have much better, easier elements to handle those.

Plugins and these embedding methods are really a legacy technology, and we are mainly mentioning them in case you come across them in certain circumstances like intranets, or enterprise projects. If you find yourself needing to embed plugin content, this is the kind of information you'll need, at a minimum:.

Pretty horrible, isn't it? Flash was even used successfully as fallback content for HTML5 video, for a time, but this is increasingly being seen as not necessary.

PDFs were a necessary stepping stone between paper and digital, but they pose many accessibility challenges and can be hard to read on small screens. They do still tend to be popular in some circles, but it is much better to link to them so they can be downloaded or read on a separate page, rather than embedding them in a webpage.

Once upon a time, plugins were indispensable on the Web. Remember the days when you had to install Adobe Flash Player just to watch a movie online?

And then you constantly got annoying alerts about updating Flash Player and your Java Runtime Environment. Web technologies have since grown much more robust, and those days are over.

For virtually all applications, it's time to stop delivering content that depends on plugins and start taking advantage of Web technologies instead.

Note: Due to its inherent issues and the lack of support for Flash, Adobe announced that they would stop supporting it at the end of As of January , most browsers block Flash content by default, and by December 31st of , all browsers will have completely removed all Flash functionality. Any existing Flash content will be inaccessible after that date.

So what should you do? Peter Elst was already writing some years ago that Adobe Flash is rarely the right tool for the job. As for ActiveX, even Microsoft's Edge browser no longer supports it. You've reached the end of this article, but can you remember the most important information? You can find some further tests to verify that you've retained this information before you move on — see Test your skills: Multimedia and embedding. The topic of embedding other content in web documents can quickly become very complex, so in this article, we've tried to introduce it in a simple, familiar way that will immediately seem relevant, while still hinting at some of the more advanced features of the involved technologies.
