If you are using WordPress 4.7 or later then go to Appearance -> Customize -> Additional CSS and add the following:
.copyright{ padding: 30px !important; }
If you are using a lower version of WordPress than 4.7, we advise you install Advanced CSS Editor plugin and follow the instructions. In Appearance -> Customize -> Advanced CSS Editor add the same code to the Global CSS area.
