An inline frame, also known as an iFrame, is an HTML element that enables the integration of another HTML document within a webpage. The embedded HTML document can include JavaScript and CSS, and is loaded when the user’s browser processes the iframe tag.

It allows web developers to include content from internal or external resources, such as a video player, a map, or a social media feed, within their web pages. The content within the iFrame is working as a separate document with its own HTML, CSS, and JavaScript, and you can style and manipulate it independently of the surrounding page.

How Does an iFrame Element Work?

It is an HTML element that is supported by all major web browsers and is included in the latest HTML5 specifications.

iFrame is used to embed content from internal ox external sources.

When a web browser encounters an iframe element, it generates a new HTML document environment to load the referenced content within. The code from the src or srcdoc is retrieved and presented as its own website, which is then embedded entirely within the parent browsing page. To the user, it appears as if the content is part of the same web page.

The child iframe operates as a complete browsing environment within the parent frame. It can load its own JavaScript and CSS independently of the parent. Additionally, it can be refreshed and loaded asynchronously from the parent site.

The parent site can define various aspects of the iframe, such as size, position, and security context. Administrators must be cautious when employing more than one inline frame element since they consume additional memory and processing power, which can degrade page performance.

The iFrame element itself does not inherently pose a security risk to your website or your audience. In fact, it was developed to assist content creators in incorporating visually appealing material for their readers. However, it’s essential to exercise caution when integrating an iFrame from an untrustworthy source.

This type of attack redirects visitors to a malicious website, which can then infect the visitors’ computers with a virus or attempt to steal sensitive information. As a result, it is not advisable to include iFrames as a fundamental component of your website.

If you suspect that a website is unsafe, refrain from linking to it and avoid utilizing its content within your website.

What Kind of Content Can You Add with iFrame?

  • Videos from video-sharing platforms like YouTube, Vimeo, etc.
  • Social media feeds from platforms like Facebook, Twitter, Instagram, etc.
