If you want to embed external content like video or audio on your website, inline frames (iframes) have proven extremely useful for that. The tags provide a simple and elegant solution to accommodate external content in a HTML document. Often, website visitors won’t even notice that they’re viewing external content. But how do you add an iframe?
Generally, a website is a single HTML document. To insert additional elements, one must use a frame which make it easy to embed documents, images or even videos. In the past, this was resolved by using normal HTML frames, but these are no longer in use nowadays. Instead, iframe tags have emerged as a popular choice to embed third-party content. The content inside an iframe is separated which means that it is loaded separately and can be navigated independently from the rest of a website.
That’s one of the reasons why inline frames are used to integrate content and components from other websites, such as YouTube videos or Google Maps. Even social media plug-ins or specific apps can be incorporated via iframes, as well as HTML documents.
Inline frames are created within the HTML code through the iframe tag.
<iframe>...</iframe>For the frame to be correctly filled out, you need to specify the following attributes:
There are some other attributes, many of which are outdated and haven’t been supported since HTML5. If you want to specify external content further, you should resort to CSS solutions for these functions.
The actual content of the iframe and part of its structure can only be arranged by using these attributes. There is generally no content inside the tag bracket. This space is used to accommodate alternative text. Where the browser doesn’t load an iframe, the text of the iframe will be displayed. However, that’s rarely the case nowadays. All popular browsers such as Chrome, Firefox and Safari can display iframe content.
A valid iframe typically looks like this:
<iframe src="http://example.org/demo.html" height="400" width="800" name="demo">
<p>Your browser does not support an iframe!</p>
</iframe>In this example, the code points to a HTML document on another website. HTML documents that are located on one’s webserver can be incorporated using an iframe tag. In this case, you just have to add the name of the file and possibly the path to the location of the desired document.
If you want to embed YouTube videos on your website, you can use inline frames. The video platform provides the appropriate code for this on the page of the relevant video.
In order to create the iframe in a way that is appealing, one must utilize CSS. In most cases, this would only create the frame itself. If the content originates from an external source, you can rarely customize the content to be displayed on your own website. With a few CSS tricks, an iframe can be integrated into a responsive web design.
Inline frames are useful if you want to embed elements from external sources into your own site. Instead of sending the user to another domain, they can continue to surf the website. As a result, user-friendliness increases considerably. In addition, the integration has some technical advantages. The iframe’s content is loaded independently from the rest of the website’s content. In this way, the content is available to the user, even when other page elements haven’t been loaded.
In reality, inline frames are becoming increasingly less important because there are drawbacks to the method. For example, it doesn’t handle embedded elements from search engines appropriately. This can affect search engine optimization and therefore the ranking of a website. The security risk associated with iframes is of greater concern. If you embed external content, it may harm your system. The content in an iframe could, for example, contain a harmful plug-in or the website owner could fall victim to a phishing attack without realizing it.
As data protection becomes a growing concern among website owners and users, iframes are hotly debated. Inline frames are often used in social media plug-ins which collect user data, even if the website visitor doesn’t interact with a ‘like’ or ‘share’ button or is a registered user.
Inline frames still have their merits when it comes to creating websites. In many cases, however, the desired effect can be achieved using alternative techniques such as CSS or JavaScript.
With HTML5, uploading video content onto your website is easier than ever. The most recent version of this popular markup language defines a new native element, video, and the associated programming interface. Website operators can also embed audio-visual content onto their online presences using video platforms such as YouTube or Vimeo.
The style sheet language CSS is one of the most important tools of modern web development. It makes it possible to separate a website’s content and layout from one another and is continuously being developed by the World Wide Web Consortium (W3C). CSS snippets facilitate the design of webpages significantly and can even take on functions of Photoshop and JavaScript. Here, we reveal some useful CSS...
