January 23, 10 min read Even though all modern browsers support them, many developers write endless articles advising against using them. I believe that their bad reputation should not prevent you from relying on them.

They have many legitimate uses cases. To help you form your own opinion and sharpen your developer skills, we will cover all the essentials you should know about this controversial tag. You may have crossed paths with it when you had to include a third-party widget like the famous Facebook like button , a YouTube video, or an advertising section on your website.

What you must keep in mind when thinking about an iframe is that it lets you embed an independent HTML document with its browsing context. That is one of the valid purposes to use an iframe: to provide a measure of separation between your application and the iframe content. The iframe can still behave in annoying or malicious ways: triggering a popup or auto-playing videos for instance. In an application, the user could create emails and save them as templates.

On a particular page, I needed to list them to let him preview and choose one. But, to prevent the CSS of the current website from affecting the style of these templates, I figured out that using an iframe with the srcdoc attribute was the cleanest solution. But the thing with these editors is that you have to find a way to keep the focus and the selection when the user is clicking on all the buttons across the interface.

Because an iframe offers an isolated environment, this means that the focus or the selection is never lost when you are clicking outside of it. By using communication events between the iframe and the parent more on how to do so later in this article , I managed to design a powerful editor in a snap.

To this day, there are eight attributes we can use to customize the behavior or styling of an iframe. You may find more than the ones listed above, but keep in mind that they are not supported in HTML5 anymore: align , frameborder , longdesc , marginheight , marginwidth and scrolling. Note : By default, the iframe element has a border around it. To remove it, you can use the style attribute to set the border CSS property to none. Because an iframe is a document, you can use most global event handlers.

When you are initiating the iframe, two of them come in handy to improve the experience, like displaying a spinner or a specific message to assist the user:. You can listen to them with the onload and onerror attribute respectively:. It is quite easy to send messages between the parent and the iframe. You have to use the postMessage function, which is documented here.

Note : Keep in mind that you can end up in some tricky situations when you need to debug something as messages are fire-and-forget i. When you are using an iframe, you are mostly dealing with content coming from a third party over which you have no control. Thus, you are increasing the risk of having a potential vulnerability in your application or simply having to deal with a bad user experience like annoying video auto-play. You have to use the sandbox and allow the attributes we discussed earlier.

Keep in mind that a good rule of thumb is to always grant the minimum level of capability necessary to a resource to do its job.

For instance, if your iframe only needs to submit forms and to open new modal windows, here is how you will configure the sandbox attribute:. For a situation when the sandbox attribute is configured, and one feature is not working correctly within the resource, it might be because it lacks a specific flag. This means that the JavaScript inside the iframe will not be executed, and all the privileges listed above will be restricted like creating new windows or loading a plugin.

The empty sandbox attribute is mostly using for static content but will drastically reduce the capability required for other resources to work properly. This allow attribute is currently experimental and only supported by Chromium-based browsers. It lets you allow whitelist specific features like letting the iframe access to the accelerometer, the battery information, or the camera. There are more than 25 available flags, so I will not list them all here.

You can browse them on the Mozilla Feature Policy Documentation. I summarized the most popular in the table below:. Thus, you should always think about placing a warning message as a fallback for those poor users. How can you render the iframe like it is actually part of the parent document i. It is still experimental and poorly supported among browsers only Chromium-based understand it.

I did not know much about this, so I had to dig a little. There are many speculations around this subject. For a long time, crawlers could not understand them, but this is no longer the case. Since search engines consider the content in iframes to belong to another website, the best you can hope for is no effect.

Iframes tend to neither help nor hurt your search engine ranking. A workaround would be to make sure to provide additional text-based links to the content they display so that Googlebot can crawl and index this content. Every iframe on a page will increase the memory used as well as other computing resources like your bandwidth.

To avoid having your iframes slow down your pages, a good technique is to lazy load them i. Keep in mind that all modern Chromium-based browsers support this at the time of this writing.

As more people browse the web using their phones, it is essential to make sure every one of your interfaces is responsive. We could dedicate an entire guide regarding the myriad of ways to make your iframe responsive. Instead, I will just link to two excellent articles:. There is also the Iframe Resizer Library , but keep in mind that it comes with a lot of additional features you may not actually need.

Note : If you are using the bootstrap library in your project, there are the embed-responsive and embed-responsiveby9 that you can use straight out of the box to make your iframes responsive. Yes my friends, there is a solution for this. Easy peasy lemon squeezy! As you can access the window element of the iframe with contentWindow , you have to do this:.

Many will even enable you to navigate inside. If your iframe does not contain another webpage but instead contains external content like a video player or an ad, it is essential to add a title to the tag. However, for the same title to be read correctly across various screen readers, it remains good practice to provide both and to make sure they match each other. Another thing to keep in mind is that when your iframe includes non-readable content like, for instance, a video game built with JavaScript , you will have to hide its contents from screen reader users using the aria-hidden attribute.

We talked about this at the beginning of this guide, but make sure to include some content inside the iframe for all the older browsers that do not support them.

LogRocket is a frontend application monitoring solution that lets you replay problems as if they happened in your own browser. Instead of guessing why errors happen, or asking users for screenshots and log dumps, LogRocket lets you replay the session to quickly understand what went wrong. Try it for free. Conclusion I hope this guide has helped you to improve your knowledge of iframes. So you should not ban them entirely from your developing arsenal but only use them in relevant situations.

If you have anything to add to this article, you can reach me in the comments below or just ping me on Twitter RifkiNada. Thank you, Nada, for this informative article! A helpful addition would be addressing accessibility issues with iframes.

There is a lot to be said about WCAG conformance an iframes. Click the link to the file and it loads into the named iframe. However when I try to load the second video it will not load in the iframe, it loads in a new tab.

An inline frame "floating frame" is a construct which embeds a document into an HTML document so that embedded data is displayed inside a subwindow of the browser's window. This does not mean full inclusion; the two documents are independent, and both them are treated as complete documents, instead of treating one as part of the other. Support to inline frames is not universal, but with a properly designed "graceful degradation" , they can be used in authoring for the World Wide Web. However, there are serious problems with printing documents containing them. This document also discusses the legal side of the matter as well as the details of the iframe element as defined in the HTML specifications, on one hand, and as implemented on IE, on the other. Thus, the content matters , despite being ignored by some browsers. See below for notes on designing that content.

React components are chunks of isolated code that can easily be shared across your entire UI, and even across multiple projects. This post will go over how to create a PDF viewing component that you can use in your projects. We will also cover an abstraction technique that you can use to help future-proof your code. First of all, we need an environment to create our component in. For this example we will be using create-react-app to generate a project.

You can optionally use CSS to change the appearance of the containing element, such as height, width, border, margins, etc. In case you were wondering, your browser embedded PDFs. However, PDF embedding is not supported by certain browsers. If you insert markup without first checking for PDF support, you could wind up with missing content or a broken UI. This ensures your users always have access to your PDF, and is designed to help you write less code. The fallback link can be customized, or the option can be disabled if you prefer.


Here is another way to display PDF inside Div by using Iframe like 2) if u don't have many pdf and if u don't know then just upload that file on google docs and then just put the share link rnasystemsbiology.org then just use ajax or jquery.

Embedding hype documents as an iframe can be useful for quickly getting a Hype animation running in a pre-existing site. Using an iframe set at those exact dimensions, you would only need to include the full URL of your hosted Tumult Hype document:. The code above has various pieces of code which ensure that there is no border and no scroll bar appears. No error, just silence.

But I could instead open a local file by swapping out the URL for a file path e. This approach will work in all modern desktop and mobile versions of Chrome, Safari, Firefox, and Edge. It will not work in Internet Explorer. If you need to support Internet Explorer or customize the user interface, you should consider the next approach -- PDF. After downloading PDF.
