Removing White Space from Storefront

Hi,

I would like to remive free space in footore between footer-widgets and site-info. I used following code but without success. I would like also decrease the width of this instagram feed widget. I’ll appreciate any help. Thank you.

.site-info {
    padding: 0.3em  !important;
	
}

.footer-widgets   {
  padding-top: 0;
	padding-bottom: 0;

	}
