An iframe is an HTML element wherein you can render an entirely different HTML document, potentially from an entirely different server. It's basically HTML inception. "iframe" is short for "inline frame"; it isn't an Apple product so I see no reason why you would capitalize the 'F'. And as you'd suspect, there is a non-inline
<frame>element, but it's been deprecated with HTML5.
An iframe takes the following form:
<iframe attr1="val1" attr2="val2" ... attrN="valN"></iframe>
attr is one of the following:
|height||pixels||Specifies the height|
|name||text||Specifies the name|
|sandbox||allow-forms, allow-pointer-lock, allow-popups, allow-same-origin, allow-scripts, allow-top-navigation||Enables an extra set of restrictions for the content|
|src||url||Specifies the address of the document to embed|
|srcdoc||html code||Specifies the HTML content of the page to show, as an alternative to src|
|width||pixels||Specifies the width|
For SSO embedding, we care mostly about the
src attribute, wherein you supply a specialized URL that automatically authenticates the viewer into the Looker instance and then retrieves some content to be displayed in the iframe.
