We have implemented a real-time dashboard in SharePoint Online. While the web part is updating [the screen refreshes every 5 minutes] we can see the underlying html (1st Screenshot) before it is fully rendered into a graphically representation (2nd Screenshot).
Questions: Is it possible to hide the web part until it is fully rendered by the browser so that we don’t see the source html, but only the final result (i.e. the graphics)? Can this be done via CSS/JavaScript embedded in the page as we have limited experience with SharePoint Designer?
Thanks in advance for your help,
Alex
