I was wondering if using out of the box Apex, it was possible to let the end user change the theme of the application.
The users don't have access to the Apex console, only to the application.
Here is the idea : http://www.apex-themes.com/stock-themes/dynamic-theme-switching/
But based on stanard themes.
End users CAN'T change the themes dynamically. But we can mimic the same. If you search forum, you will find quite number of threads on this and approach is more or less same - Point to different CSS files dynamically
