Hi Chris, I just finished the Mozilla Splash Page Assessment. I discovered the video I embedded from YouTube doesn’t play (disabled) anytime I use the sandbox attribute on the <iframe> element.

However, if I removed the sandbox attribute, it would play. I even tried using the allow-scripts value on the attribute; it still didn’t work.

It is probably something to do with the YouTube API not allowing its usage, for various reasons. I don’t know exactly why - something to do with security, and Google’s wish to regulate how the content is manipulated.

So I am learning here that solving the problems is the part of the creative work as a web developer or any occupation related to this world of internet where people Explore, Learn, Apply, Create and Contribute. Great !

Dear Mozilla,

First off, thank you for providing the excellent “Learn Web Development” tutorial and associated MDN resources. Phenomenal stuff.

I was wondering if you could provide some general feedback on my Mozilla-splash-page exercise. I noticed it doesn’t scale very well past < ~360px when inspected in responsive design mode (words / icons get truncated, go off screen) despite example solution picture being 321.5px and looking fine. Is that a default behavior or do I need to make some significant changes?

Any input appreciated.

Kind Regards
Martin P.
