The October 2026 “What’s new for developers” update on developer.wordpress.org brings a welcome change: Gutenberg 24.1 made the viewport state helpers public. The @wordpress/block-editor package now exports getStyleForState() and setStyleForState(), with new getSelectedBlockStyleState() and hasSelectedBlockStyleState() selectors in the block editor store. In practice, custom blocks can now offer per-breakpoint settings the way Core blocks do — a minimum height for the mobile breakpoint only, or a header that’s sticky on mobile and static on desktop — without private-API hacks.

For site owners, this means richer responsive options coming to block plugins and themes, and cleaner mobile experiences with fewer custom-CSS workarounds. If your site feels clumsy on phones, ask your developer whether your blocks are taking advantage of these native controls.

We build and optimize WordPress sites for every screen — from custom Gutenberg blocks to full responsive redesigns. Learn more at https://qamardigitalventuresllc.com/
