What’s new in Gutenberg 15.1? (8 February)

“What’s new in GutenbergGutenberg The Gutenberg project is the new Editor Interface for WordPress.

(Not to be confused with post tags.)) are posted following every Gutenberg release on a biweekly basis, showcasing new features included in the release. As a reminder, here’s an overview of different ways to keep up with Gutenberg and the Site Editor project (formerly called Full Site Editing).

Gutenberg 15.1 has been released and is available for download!

This release sees the integration of Openverse through the Media tab, the addition of custom CSSCSS Cascading Style Sheets. per 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. via the styles sidebarSidebar A sidebar in WordPress is referred to a widget-ready area used by WordPress themes to display information that is not a part of the main content. It is not always a vertical column on the side. It can be a horizontal rectangle below or above the content area, footer, header, or any where in the theme. and theme.jsonJSON JSON, or JavaScript Object Notation, is a minimal, readable format for structuring data. It is used primarily to transmit data between a server and web application, as an alternative to XML., navigation menus in the browse mode sidebar, and the facility to add shadow presets in global styles.

Table of Contents

Openverse integration in the Inserter

Openverse is now integrated into the Inserter in the Editor. It is now possible to get access to an extensive library of free stock photos that are available for free use, directly from the Media tab.  (46251)

Global Styles now supports shadow presets

Access to shadow presets from the UIUI User interface of Global Styles has been added to Gutenberg 15.1. There are now four shadow presets (Natural, Crisp, Sharp and Soft) defined by default, but new and custom ones can be defined for the theme via ‘theme.json’. (46502)

Add custom CSS on a per-block basis

It is now possible to add custom CSS styles on a per-block basis. Custom CSS can be added via the Global Styles UI, which will be applied to all the block occurrences. Default CSS styles can also be defined for each block via theme.json.  (46571)

Gutenberg 15.1 introduces Navigation to the browse mode sidebar in the Site Editor. This enables the user to manage their site’s navigation menus from within, thereby providing a more integrated site editing experience. (46436). This navigation menuNavigation Menu A theme feature introduced with Version 3.0. WordPress includes an easy to use mechanism for giving various control options to get users to click from one place to another on a site. also includes the items of each menú so we can navigate through them directly from the Site Editor sidebar. (47387)

Other notable highlights

New menu options for copying and pasting styles between blocks

Applying the styling from one block to another can now be done more readily with the addition of a new group in the Options menu of the block’s toolbar. The new group contains the options to “Copy styles” and “Paste styles”. Previously only the “Copy styles” option was available, leaving it unclear how to paste them into the receiving block. The process is now clearer and more easily discoverable. (47430)

Featured images in templates can be sized

The release of Gutenberg 15.1 brings the ability to adjust the size of the featured imageFeatured image A featured image is the main image used on your blog archive page and is pulled when the post or page is shared on social media. The image can be used to display in widget areas on your site or in a summary list of posts. placeholder in the single post and single page templates from within the Site Editor UI.
