dhtmlxScheduler calendar not work with "<!doctype html>"

I have a web page and use with dhtmlxScheduler calendar
Everything works perfectly in Google Chrome and other browsers.
Does not Work in Windows Explorer,

If you place the label: </ doctype html> calendar is not displayed,
please help!!!

Please provide any kind of sample where it can be checked.
The dhtmlxScheduler works correctly with IE8+ in standard mode
The above doctype is actually a recommended one, so it must work definitely.

Try to set fixed sizes in styles of the scheduler’s container ( if you are using percent based sizes, or not defining sizes at all, it is possible that scheduler’s container has a zero height )

Thanks, I solved the case!!! :slight_smile:
