<blockquote>
See exactly how many columns appear on every device. Responsive Columns extends the core Columns block and the Query Loop (grid) template with precise controls for four breakpoints, X/Y gap management, and an optional Masonry layout.
</blockquote>
<h3>Key features</h3>
<ul>
<li>Four responsive breakpoints. Fine-tune Desktop, Tablet landscape, Tablet portrait, and Mobile column counts (1–6 columns).</li>
<li>Theme-aware gaps. Uses your theme’s block gap as a starting point and lets you override horizontal and vertical spacing independently.</li>
<li>One-click Masonry for Query Loop (Grid). No jQuery, automatically reflows posts as your content changes.</li>
<li>Native block experience. Works directly inside core/Columns and core/Post Template (grid) so patterns, reusable blocks, and theme.json continue to work.</li>
<li>Lightweight. Modern ES modules (~4 kB compressed) and CSS custom properties. Editor assets load only when needed.</li>
</ul>
<h3>How it works</h3>
The plugin adds a <code>has-s1-rc-columns</code> class and a handful of CSS custom properties:
<pre><code>--s1-rc-columns-mobile-portrait
--s1-rc-columns-mobile-landscape
--s1-rc-columns-tablet-portrait
--s1-rc-columns-tablet-landscape
--s1-rc-columns-desktop /* auto-added for Masonry /
--s1-rc-gap-x / horizontal /
--s1-rc-gap-y / vertical, falls back to X */
</code></pre>
Your theme’s layout styles stay in control — Responsive Columns only adjusts <code>grid-template-columns</code> and gap values inside media queries. Disable or uninstall the plugin and the columns fall back to WordPress defaults without leaving orphan styles behind.
<h3>Editor experience</h3>
<ul>
<li>Inspector panel with device icons, tooltips, and numeric inputs for precise values.</li>
<li>Theme gap detection with a reset button to restore defaults in one click.</li>
<li>Gap linking lets you mirror vertical spacing or split it into a custom row gap.</li>
<li>Masonry toggle explains prerequisites (Query Loop + Grid layout with a desktop column count).</li>
</ul>
<h3>Accessibility & localisation</h3>
<ul>
<li>All UI controls are keyboard accessible and include human-readable labels.</li>
<li>Strings are translation ready via the <code>responsive-columns</code> text domain and JSON translation support.</li>
</ul>

Responsive Columns

Adaptive column counts, gap controls, and Masonry layouts for core Columns and Query Loop blocks — no custom blocks required.

NOTE: This plugin was originally created to solve the issue of splitting classic editor content into divs, using shortcodes. On Sept 27th, 2022, I tested to see how this plugin works with Gutenberg and it actually still works fine (because the divs are rendered AFTER Gutenberg does it’s thing). But it’s worth mentioning that there is a Group block in Gutenberg that serves the same purpose, and might be more intuitive than working with shortcodes for some users. That said, if you’ve disabled Gutenberg in favour of the classic editor, this plugin is still useful. And although I’m not adding new features, I will fix any bugs people report.
Now on to how it actually works:
Separate your WordPress post or page content into divs with (optional) custom CSS classes and ids. Adding the shortcode [divup] in between some content will split the content into 2 separate divs.
You can enter as many [divup] shortcodes to a post or page as you like. Great for creating columns of content for magazine style websites while keeping shortcode markup to an absolute minimum. DivUp Content never uses inline styles, but it does automatically give divs fiendishly clever classes like first, last, div-1, div-2, div-3, and div-odd, div-even, mul-3, mul-4 (multiple of 1,2,3,4 etc). You can then create your own style rules for the divs in style.css or with <a href="http://themeover.com/" rel="nofollow ugc">Microthemer</a> (a visual design CSS plugin for customizing WordPress sites).
<h4>3 Column Example CSS</h4>
The CSS for a 3 column layout could be:
.divup-wrap { 
 display: grid; 
 grid-template-columns: repeat(3, 1fr); 
}
<h4>6 Column Example CSS</h4>
For a 6 column layout (with gaps), you would just change the CSS to:
.divup-wrap { 
 display: grid; 
 grid-template-columns: repeat(6, 1fr); 
 gap: 2rem; 
}
For more complex grid layouts with content spanning different numbers of columns and rows, you may find <a href="http://themeover.com/" rel="nofollow ugc">Microthemer</a>‘s visual controls for generating the CSS grid rules quite handy. Just select the .divup-wrap element when editing with Microthemer, and then position the grid items however you like using drag and drop.
<h3>Features added</h3>
NEWEST: 
Added support for adding custom HTML attributes to divs/spans. Use [startwrap custom=’title: read this’] or [divup custom=”data-src:image.jpg”] (the custom attribute can be applied to both [startwrap] and [divup] shortcodes. 
You can also do[startwrap custom=’title: read this|required:some value’] (seperate with a | pipe character for multiple) 
When using [divup], two divs will be created. To apply custom attributes to the first and second divs use a comma e.g.[divup custom=”data-src:image1.jpg, data-src:image2.jpg”]
NEWER: 
Added support for span elements. Use [startwrap type=’span’]. 
Added support for no superfluous child elements. Use [startwrap parent=0] or [startwrap parent=’false’].
NEW: You can also add multiple [startwrap] and [endwrap] shortcodes to control how the divs are wrapped in a wrapper div. This overrides the original auto-wrapper functionality if you choose to use it.**
The best way to understand how DivUp Content works (including the advanced aspects) is to **copy and paste the ONE of the following dummy content examples below into a post or page and then inspect the html with your browser (Right-click > Inpsect) ** – paying attention to the CSS classes it automatically applies to the divs.

DivUp Content

Simple and very useful. I initially had a minor issue with WP 4.4.1, but this was immediately fixed. Thanks to the author for being so reactive!



Perfect

Wrap divs around classic editor content using divup shortcodes. Also works for Gutenberg, but you may prefer to use the group block.
