HTML <iframe> tagS2C Home   « HTML <iframe> tag

Definition

The <iframe> tag is used to define nested browsing context such as an inline frame that holds another document.

Pre HTML5, some text could be added between the opening and closing <iframe> tags as a fallback for when the <iframe> tag wasn't supported in a browser, this is no longer allowed and will cause an error when validating a HTML5 document.

Example

The example below is embedded in the page so you can see an inline frame in real time and is a snapshot of the jQuery Reference - Attributes & Properties - .position() method taken from another of my tutorial sites.

The following html code is used to render an iframe inline in real time.


<iframe src="https://learnjavascript.co.uk/jq/reference/ap/position2.html" width="300" height="300">
</iframe>
