If you use <a href="https://codex.wordpress.org/Gallery_Shortcode" rel="nofollow ugc"><code>[gallery]</code></a> shortcode without setting the columns value, the default is set to 3. Some WordPress theme can either fit 3 or more column per row or less.
Imagine if you use <code>[gallery]</code> shortcode with default options regularly within your posts, you switch to a new theme and the theme could only fit gallery with 2 columns per row.
To overcome this issue, the plugin will force and overwrite the current number of gallery columns within any post that uses <code>[gallery]</code> shortcode with a new number of columns of your choice without altering or tampering its original options. It also includes feature to exclude post from being overwritten by this plugin and removing the default inline styles printed when the <code>[gallery]</code> shortcode is used.

Bamboo Manchester

This plugin provides several shortcodes for organising your content into multi-column layouts. It supports two, three and four column layouts and allows for content to span multiple columns if required.
Usage
Insert the required shortcodes into your content as follows:
2 column layout:
<pre><code> [column-half-1]
 First column of content
 [/column-half-1]
 [column-half-2]
 Second column of content
 [/column-half-2]
</code></pre>
3 column layout:
<pre><code> [column-third-1]
 First column of content
 [/column-third-1]
 [column-third-2]
 Second column of content
 [/column-third-2]
 [column-third-3]
 Third column of content
 [/column-third-3]
</code></pre>
4 Column layout:
<pre><code> [column-quarter-1]
 First column of content
 [/column-quarter-1]
 [column-quarter-2]
 Second column of content
 [/column-quarter-2]
 [column-quarter-3]
 Third column of content
 [/column-quarter-3]
 [column-quarter-4]
 Fourth column of content
 [/column-quarter-4]
</code></pre>
If you want content to span multiple columns you can combine the shortcodes to create a column spans multiple spaces, for example:
<pre><code> 1 Third / 2 Thirds

 [column-third-1]
 First column of content
 [/column-third-1]
 [column-third-2-3]
 Second column of content that spans the second and third columns
 [/column-third-2-3]

 1 Quarter / 2 Quarters / 1 Quarter

 [column-quarter-1]
 First column of content
 [/column-quarter-1]
 [column-quarter-2-3]
 Second column of content that spans the second and third columns
 [/column-quarter-2-3]
 [column-quarter-4]
 Third column of content that occupies the fourth quarter column
 [/column-quarter-4]
</code></pre>
If you need to embed a set of columns within a column, you can do so by adding ‘inner-‘ to the shortcode as follows:
<pre><code> [column-half-1]
 Some Text
 [inner-column-half-1]
 Some more text
 [/inner-column-half-1]
 [inner-column-half-2]
 Even more text
 [/inner-column-half-2]
 [/column half 1]
 [column-half-2]
 The final text
 [/column-half-2]
</code></pre>
You can also change the background colour of a colour by adding an attribute to the shortcode as follows:
<pre><code> [column-half-1 background="e8e8e8"]
</code></pre>
