Is there a alternative for that because Firefox and Internet Explorer are not supporting it...
Example:
I ran across this while looking for something to use instead of datetime-local
https://www.daterangepicker.com/
It has similar functionality to datetime-local
and some extra. The one thing you would have to account for is being able to limit users' changing the date values in the input box if you do it that way. datetime-local
automatically prevents say, putting letters into the time values.
Otherwise, Jonathan's answer still seems the best basic built-in option that works with FF/Chrome.
