Modifying size of date-picker?

[MrClue]

I need a way to responsively modify the calender so that it takes up the entire availalbe width of its parent container, while making sure that the aspect ratio stays the same.

I am unable to find any documentation regarding sizing the calendar, but was able to override some css variables to change the width and height of cells. However it does not look "right", and was wondering if anyone else have had the same issue, and possibly have a solution?
