When in author Mode everytime if I am adding any component and removing it it is taking extra space at the bottom when I check in view as published or refresh the page it works fine is there any fix for this.
Try to use a cq:listener with "afterdelete","afterinsert" property to refresh the component/page, that should solve your problem
