Embed a mechanism to enable iframe resizing to host page #316

Open andrie opened 4 years ago

The iframeResizer JS library contains a two-part solution that posts messages between the host page and the iframe contents.

If learnr embeds the iframeResizer.contentWindow.min.js then the hosting page can embed the iframeResizer.min.js.

If we also get pkgdown to embed the iframeResizer.min.js component, then the resizing will happen out of the box for all pkgdown sites that embed tutorials.

I have a working prototype of this for the exercises at https://sys-admin-training.netlify.com/
