Color and typography presets in Global Styles

Color and typography presets that are defined in theme variations are now exposed within the color and typography sections of Global Styles. This new feature allows users to mix and match color presets or typography from different variations, offering greater flexibility for designs from a given theme. (56622)

Indenting List blockBlock Block is the abstract term used to describe units of markup that, composed together, form the content or layout of a webpage using the WordPress editor. The idea combines concepts of what in the past may have achieved with shortcodes, custom HTML, and embed discovery into a single consistent API and user experience. items via the tab key

The List block now supports indenting and outdenting when the selection is at the beginning of the List item. This improves the usability of the List block by allowing indenting via the keyboard, while still preserving existing tabbing behavior in the editor canvas when the selection is elsewhere within the block. (59199)

Shuffle option when choosing patterns

When a pattern is inserted and has categories defined, and where the pattern contains a single top-level block such as a Group block, a shuffle button is exposed in the block toolbar that allows a user to cycle through random patterns. This makes it easier to quickly browse through a variety of available patterns in specific scenarios. (59251)

Swap Template Parts in the Inspector

Screenshot of replace flow for template parts in the block inspector controls.

When selecting a Template Part in the site editor, the replace flow is now more discoverable with previews of alternate Template Parts available to select from the block inspector controls. This allows for a more at-a-glance approach to browsing different options for swapping out headers and footers. (55128)

Other Notable Highlights

  • Background images can now be set in the root of theme.json to provide site-wide background images (59354). There is currently no UIUI User interface for it in Global Styles, and this will be explored in future releases.
  • For container blocks that use allowedBlocks, insert before and after actions are now supported on child blocks (59162).
  • Use drag handles to set row and column span and see a dotted outline of block placement when the new “Grid interactivity” experiment is enabled (59052).
