You can style your site’s copyright area by going to Customize > Footer > Copyright area (Style tab). The styling options include colors, paddings, and dividers.
Colors
Add your own colors to the copyright footer by changing the background and text color.
Divider
The divider adds a border between the copyright area and the footer widgets that precede it. You can configure its thickness, color and you can also have it contained or fullwidth.
Paddings
The final set of styling options is the one for paddings. Take control of the copyright area’s spacing by using the top and bottom padding options.
