This plugin is currently aimed at developers so it doesn’t come with any CSS or JavaScript, it just ads the DIVs for the columns, the rest is up to the developer’s imagination. This will allow developers to easily add column functionality to custom WordPress implementations.
<h3>Usage</h3>
How do users use it?
To split the content into columns, you simply add the shortcode [columnbreak] where you want the one column to end and the next one to start.
It will add a container around the columns with the class ‘ninja_columns’ and the class ‘colsid_{post-id}’ that will allow you to target the post or page specifically.

Ninja Columns

With <a href="https://github.com/pixelgrade/pixcodes" rel="nofollow ugc">PixCodes</a> you can have a shortcode insert interface for the WordPress Classic Editor.
PixCodes is intended for Classic Editor and TinyMCE workflows. It does not add a block editor interface.
The awesome part is that you can filter any shortcode parameters or overwrite any shortcode template with your theme.
Note: this plugin does not add any style to the output of shortcodes.
We believe that shortcodes functionality should be offered by a plugin and the style should be provided by themes.
Here is a <a href="http://github.com/pixelgrade/pixcodes/blob/master/README.md" rel="nofollow ugc">detailed documentation</a> about how you can configure some plugin settings and output.
