Hi there,
follow these steps:
1. Create a New Block Element, set the Element Type to Site Footer.
2. Set the Display Rules to Entire site.
3. Now build the footer.
3.1 Starting with a GB Container Block, in the blocks toolbar set the Text Align to Center.
In its Spacing settings add some Padding eg, 40px.
In its Color set the Background.
3.2 inside a GB Image Block and set its Width.
3.3 Add a Navigation Menu block.
3.4 Add a Headline Block for the Copyright
NOTE in the Site Footer Element you can add this {{current_year}} to the Headline to display the current year in your copyright.
The GB Image Block and Headline Block both have full style controls so you can use there Spacing > Margins to add space between them.
