If you’d like to change the column width for the footer widgets use this code in your child themes > functions.php, in the example below I’ve changed the width from 3 to 6 columns wide (note: span_6), keep in mind the theme was built on a 12 column grid.
add_action( 'after_setup_theme', 'ct_parent_sidebar_override' ); function ct_parent_sidebar_override() { unregister_sidebar('Footer'); register_sidebar(array( 'name' => 'Footer', 'id' => 'footer', 'description' => 'Widgets in this area will be shown in the footer.', 'before_widget' => '<aside id="%1$s" class="widget col span_6 %2$s">', 'after_widget' => '</aside>', 'before_title' => '<h5>', 'after_title' => '</h5>', )); }
