Creating a New Layout

Layouts are blocks of code that control the HTML structure of a particular section of the template rendering. By default, Gantry comes with several built-in layout files located in the wp-content/plugins/gantry/html/layouts/ folder:

Step 1: Purpose

The default layout that ships with Gantry Framework is designed to be flexible enough to handle the needs of 99% of the possible implementations. However, there are occasions when the default HTML structure does not contain all the blocks elements or class names required to realize a particular design.

In these rare cases, you can utilize the power of the Gantry framework to override the default layout with your own, template-provided one. Certain instances, such as widget layouts, are flexible enough to support your own custom layouts. You can even call them in the same way the default layouts are called.

Step 2: Create/Copy New Layout Files

The simplest way to do this is to copy an existing layout. In this example, we'll copy the body_mainbody.php layout and modify it after. The files are located under:

[YOUR_SITE]/wp-content/plugins/gantry/html/layouts/

However, you do not want to modify the core Gantry files. Instead, copy the new layout file to:

[YOUR_SITE]/wp-content/themes/YOUR_TEMPLATE/html/layouts/

You may have to create a layouts/ folder if one does not already exist.

In this case, copy body_mainbody.php from the core layouts location into the template layouts location.

Step 3: File Structure

After you have copied the body_mainbody.php file, you can open it up and edit it to fit your needs. By default, it looks like this:
