Create a column group with the <code>[column-group]</code> shortcode, then add columns to the group with the <code>[column]</code> shortcode, like this:
<pre><code>[column-group]
 [column]This is my first column[/column]
 [column]This is my second column[/column]
[/column-group]
</code></pre>
You can also span columns, like this:
<pre><code>[column-group]
 [column span="2"]This is my first column spanned across two columns.[/column]
 [column]This is my second column[/column]
 [column]This is my third column[/column]
[/column-group]
</code></pre>
The first column will be twice as large as the second or third.
Styles are in columns.css. If you’d like your own margins and stuff, dequeue the columns.css style during <code>wp_enqueue_scripts</code> with a priority of 11 or more.

Columns

This WordPress plugin boosts your website with... you guessed it, columns!

CWRUCAS

Code is adapted from the plugin ‘Columns’ by Konstantin Kovshenin.
Bootstrap is an HTML, CSS, and JS framework that is used to develop responsive, mobile websites. It employs a grid system that divides the viewport into twelve distinct columns. On desktops, the columns scale proportionally to the width of the viewing area while on mobile devices and tablets the columns stack on top of one another. This plugin takes advantage of that grid system to allow for WordPress content to be split up equally between the twelve columns.
To create a group of columns, use the [column-group] shortcode. To add columns to a group, use the [column] shortcode. For example:
<pre><code>[column-group]
 [column]This is the first column[/column]
 [column]This is the second column[/column]
[/column-group]
</code></pre>
The first column will occupy the first six columns of the Bootstrap grid while the second column will fill the remaining six.
<h4>Spanning Columns</h4>
The plugin’s columns can also be manually spanned across the Bootstrap grid. By adding the span attribute to the starting column shortcode, the number of Bootstrap columns that the WordPress columns take up can be assigned. For example:
<pre><code>[column-group]
 [column span=“4”]This is the first column.[/column]
 [column span=“6”]This is the second column.[/column]
 [column span=“2”]This is the third column.[/column]
[/column-group]
</code></pre>
The columns will take up four, six, and two of the Bootstrap columns respectively. Note: The span value is actually a ratio so if the total value of the spans in a column group does not equal twelve, then the plugin will assign the column sizes by means of percentage.
