Footer settings can be decided via theme options ( Theme Options -> Footer ), see image below.
You can disable the display of the footer, showing the colored gradient and you can decide how many columns to use for your footer.
To decide the content of your footer go to Appearance -> Widgets and use the appropriate Sidebar (Footer 1, Footer 2, Footer 3 and Footer 4). Enter your favorite widgets to customize the footer.
