Most of the Domino homepage is built with widgets. Manage them in Appearance → Widgets.
Widget areas
Homepage:
Right of Slider — the columns next to the slideshow (the demo’s Latest and Our Picks).
Below the Slider (full-width) — a full-width band under the featured area.
Featured Categories (Homepage) — the magazine sections; stack Featured Category widgets here, one per section, and add Custom HTML widgets between them for ad banners.
Video Area — the dark full-width section for video content.
Site-wide:
Sidebar — next to the content.
Header Social Icons — the top-bar icons; use the free Social Icons Widget by WPZOOM plugin with the Color Icon/No Background style.
Footer: Column 1–4 — the footer columns.
Theme widgets
Featured Category and Featured Categories (2 columns) — the homepage category sections.
WPZOOM: Carousel Slider — a scrollable posts carousel, great for the full-width band under the slider.
WPZOOM: Popular Posts — posts ranked by comments.
WPZOOM: Tabs — a tabbed box combining several post lists in one compact widget.
WPZOOM: Recent Posts — a compact recent-posts list with thumbnails.
