Description

Responsive Columns extends the core Columns block and the Query Loop grid template with precise controls for desktop, tablet, and mobile breakpoints, flexible X/Y gap management with px / rem / em support, native Query Loop auto-fit support, advanced Custom widths controls for asymmetric core/Columns layouts, and an optional Masonry layout.

Key features

Five responsive breakpoints, including Desktop, tablet, and mobile layouts.
Shared breakpoint switching for column and gap controls.
Custom widths mode for core/Columns when equal-width responsive columns are not enough.
Per-column responsive Width controls for complex core/Columns layouts.
Simple per-breakpoint column order controls with Default, First, and Last.
Theme-aware gaps with separate column and row spacing controls.
px / rem / em support for Gap and Row gap.
Gap inheritance across smaller breakpoints with per-breakpoint overrides.
Native Query Loop Grid item position integration for Manual and Auto layouts.
Minimum column width support for Query Loop grids in Auto mode.
Safer Masonry rules with active-breakpoint validation for Query Loop grids.
Native block support for core/Columns and core/Post Template.
Lightweight output based on CSS custom properties and small front-end assets.

How it works

The plugin adds a has-s1-rc-columns class and a small set of CSS custom properties:

--s1-rc-columns-mobile-portrait
--s1-rc-columns-mobile-landscape
--s1-rc-columns-tablet-portrait
--s1-rc-columns-tablet-landscape
--s1-rc-columns-desktop
--s1-rc-gap-x
--s1-rc-gap-y

Your theme stays in control of the base layout. Responsive Columns only adjusts the number of columns and gaps at the configured breakpoints. If the plugin is removed, the blocks fall back to their normal WordPress behavior without leaving custom block markup behind.

Editor experience

Responsive controls live inside the block inspector with a shared breakpoint selector.
Core/Columns can switch between standard equal-width responsive columns and Custom widths for per-column overrides.
Query Loop auto-fit follows the native Grid item position setting instead of duplicating it.
Gap defaults are pulled from the active theme when possible.
Gap controls support px, rem, and em while keeping reset and inheritance behavior predictable.
Masonry availability is validated against the active breakpoint before it can be enabled.
Local reset actions restore responsive values back to the active theme defaults.

Accessibility and localization

Inspector controls are keyboard accessible and labeled for screen readers.
Strings are translation-ready via the responsive-columns text domain.

Installation

Upload the plugin folder to /wp-content/plugins/ or install Responsive Columns from the WordPress plugin directory.
Activate the plugin.
Select a Columns block or a Query Loop using the grid layout, then open the Responsive Columns panel in the sidebar.

FAQ

Does it work with reusable blocks and patterns?: Yes. Settings are stored as native block attributes, so they remain with reusable blocks, synced patterns, and template parts.
Will layouts break if I uninstall the plugin?: No. WordPress ignores the extra attributes after the plugin is removed, so content falls back to the default responsive behavior.
Can I use rem or em values for gap controls?: Yes. Gap and Row gap support px, rem, and em, while older saved px values remain fully compatible.
Does it depend on a specific theme?: No. The plugin extends native core blocks and keeps the active theme in charge of layout styles and spacing tokens.
