I want to adjust my height of every fieldset according to the length of fields present in it. how can i do this?

Answer 1

Fieldsets automatically adjust in height to contain the form elements contained within. No additional CSS is required.
The fieldsets must contain form fields obviously; not 100% sure why you've omitted them from your example code.
