Found a bugbugA bug is an error or unexpected result. Performance improvements, code optimization, and are considered enhancements, not defects. After feature freeze, only bugs are dealt with, with regressions (adverse changes from the previous version) being the highest priority.?Create a ticket in the bug tracker.
In addition to a number of improvements and features for the blockBlockBlock 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. editor, WordPress 5.3 comes with new Block-related APIs for developers.
Server-side block style variations APIAPIAn API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways.
It includes server-side helpers that simplify registering and unregistering block styles.
The register_block_style function receives the name of the block as the first argument and an array describing properties of the style as the second argument.
The properties of the style array must include name and label:
name: The identifier of the style used to compute a CSSCSSCascading Style Sheets. class.
label: A human-readable label for the style.
Besides the two mandatory properties, the styles properties array should also include an inline_style or a style_handle property:
inline_style: Contains inline CSS code that registers the CSS class required for the style.
style_handle: Contains the handle to an already registered style that should be enqueued in places where block styles are needed.
The following code sample registers a style for the quote block named “Blue Quote”, and provides an inline style that makes quote blocks with the “Blue Quote” style have blue color:
Alternatively, if a stylesheet was already registered containing the CSS for the style variation, it is possible to just pass the stylesheet’s handle so register_block_style function will make sure it is enqueued properly.
Important: The function unregister_block_style only unregisters styles that were registered on the server using register_block_style. The function does not unregister a style registered using client-side code.
Props to @jorgefilipecosta for helping with this dev notedev noteEach important change in WordPress Core is documented in a developers note, (usually called dev note). Good dev notes generally include a description of the change, the decision that led to this change, and a description of how developers are supposed to work with that change. Dev notes are published on Make/Core blog during the beta phase of WordPress release cycle. Publishing dev notes is particularly important when plugin/theme authors and WordPress developers need to be aware of those changes.In general, all dev notes are compiled into a Field Guide at the beginning of the release candidate phase..
