Yith Proteo Footer Widget Spacing

Dear Support,
I am using footer widget area1 and area2. In area1 I have text, in area2 I have images.
I would like the space between area 1 and area 2 to be less. I have used the following CSS, but it is not making the padding or margins decrease.

#main-footer div[class^=footer-sidebar] {
    padding-bottom: 0;
	  padding-top:0;
}

.footer-sidebar-2 .widget {
    margin-bottom: 10;
	  margin-top: 0;
}

Please could you help me?

Many thanx
Eunice
