# Layout

Structural blocks that arrange, group, and space out your content.

| Block                                                              | Description                                                                                                                                                                                                                         |
| ------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| [Group](/helix/theme-blocks/layout/group.md)                       | A container that holds other blocks and arranges them as a row or column. Groups are the foundation of custom layouts — nest blocks inside to align them, share a background, or turn a set of blocks into a single clickable card. |
| [Accordion](/helix/theme-blocks/layout/accordion.md)               | Collapsible rows built from the blocks you nest inside — ideal for FAQs, product details, or shipping information.                                                                                                                  |
| [Divider](/helix/theme-blocks/layout/divider.md)                   | A horizontal rule for separating content blocks.                                                                                                                                                                                    |
| [Spacer](/helix/theme-blocks/layout/spacer.md)                     | Adjustable empty space for precise vertical rhythm between blocks.                                                                                                                                                                  |
| [Marquee](/helix/theme-blocks/layout/marquee.md)                   | A continuously scrolling strip of content. Fill it with nested blocks and they scroll as one repeating band.                                                                                                                        |
| [Carousel](/helix/theme-blocks/layout/carousel.md)                 | A horizontal slider that shows its child **Slide** blocks a few at a time, with navigation, pagination, and autoplay.                                                                                                               |
| [Columns](/helix/theme-blocks/layout/columns.md)                   | A responsive grid of equal-width **Column** blocks, each holding its own content. Use it for feature rows, icon grids, or any side-by-side layout.                                                                                  |
| [Masonry](/helix/theme-blocks/layout/masonry.md)                   | An asymmetric grid of **Item** blocks that keeps each tile's natural height, so tiles of different sizes pack together. Optionally cap the height and reveal the rest behind a show-more button.                                    |
| [Comparison table](/helix/theme-blocks/layout/comparison-table.md) | A table that puts products, plans, or tiers side by side — for example "Basic vs Pro vs Premium". Built from a **Feature** block holding the row labels and one **Column** block per option.                                        |
