When you are using the SiteKiosk Windows Chrome Browser you can activate the Chrome DevTools to debug web pages in SiteKiosk.
To activate this option, you need to create an empty text file with the file name debug.txt. This file must be placed in the folder ..\SiteKiosk\Chromium\.
When you start SiteKiosk with the Chrome Browser engine after that change, you can click on the browser pane of SiteKiosk and hit the F11 button to open up the Chrome DevTools window.
Remember to delete or rename the debug.txt file after you are done with debugging.
