Adds support for using Zurb’s Foundation grid-system via shortcodes in WordPress’ TinyMCE editor.
For more information about Foundation, please <a href="http://foundation.zurb.com/docs/" title="Zurb Foundation" rel="nofollow ugc">read the docs</a>.
This plugin is compatible with version 5 and version 6 of Foundation, and includes support for small, medium and large breakpoints.
Now also with support for block grids.
Modifying the grid
If your grid has more than the default 12 columns you can use the <code>foundation_columns_count</code> filter.
<pre><code>add_filter( 'foundation_columns_count', function($count) {
 $count = 16;
 return $count;
} );
</code></pre>
If you would like to contribute to this plugin. Please open a pull request on <a href="https://github.com/tormjens/foundation-columns" rel="nofollow ugc">Github</a>
Please note: This plugin does not install Foundation for you and therefore require that you use a theme built on Foundation.

You can add a gallery just as you normally would including setting up the number of columns.
The plugin supports up to 6 columns for any gallery, it will fall back to 4 column grid for invalid values.
MOBILE: Note that the foundation mobile classes have already been added for each gallery size. 
That said you can use the filters below to alter any foundation classes applied to the 
block grid.
There are also a number of filters devs can use to alter output.
