This might be one of the more daft questions to ask,
but since
<iframe src="view-source:https://ry3yr.github.io/OSTR/Diarykeepers_Homepage/Daymusic.html" width="800" height="600"></iframe>
doesn't work:
Is it possible to display a page's source inside an iframe? (Or any other way really ??)
CLARIFICATION: I know about the browsers built in "view source" function. I want the page source being rendered without user interaction.
