How to reduce the height of the footer

Hi,

I would like to reduce the height of the footer. But I have already removed the padding, see the CSS scripts I added below:

#containerfooter {
padding-top: 0;
}
.footercredits {
padding-top: 0;
padding-bottom: 0;
}

The footer’s height was reduced. But I think it’s still not enough.

Thanks!
