# Group Group blocks are used to create nested collections of blocks; they may also be given a background colour, allowing you to break up the appearance of a page. Blocks may be moved within a group, or the block may be moved on the page, which will update move its contents too.
Adjusting a Group will adjust the blocks within it as well, e.g. reducing the width of the Group will make the blocks within it smaller, or changing the background colour of the Group will override the background colour of blocks within it.
To add a block to a Group, simply drag and drop it over the Group. ## Appearance [](https://bookstack.iconography.co.uk/uploads/images/gallery/2024-11/Y2wimage.png) ## Editing the Block ### SettingsField | Purpose |
